Melasma (historically chloasma) remains a complex, recalcitrant pigmentary disorder affecting millions worldwide. This article elucidates the paradigm shift in management strategies observed in early 2026 for Fitzpatrick III-VI, its comparison with Fitzpatrick I–III, and the transition from aggressive mono-therapies to a multi-layered, synergistic approach. To locate, select, and extract relevant data, a comprehensive search of recent clinical protocols and emerging technological studies was conducted. This literature was systematically synthesized to evaluate novel therapeutic targets, specifically vascular modulation, basement membrane repair, and epigenetic modification in Fitzpatrick IV–VI. Key focus areas included the safety of "hydroquinone (HQ)-free" maintenance agents, systemic use of low-dose tranexamic acid (TXA), and athermal technologies. Findings revealed a definitive phototype-dependent divergence in clinical outcomes. In Fitzpatrick I–III, traditional cytotoxic agents (HQ) and photothermal devices yielded high clearance with minimal sequelae. Conversely, in Fitzpatrick IV–VI, these same aggressive modalities statistically correlated with severe adverse events, including exogenous ochronosis and post-inflammatory hyperpigmentation. For melanin-rich skin, synthesized data established biological modulators (5% stabilized cysteamine, Thiamidol) and systemic stabilizers (low-dose oral TXA) as superior alternatives, effectively suppressing vascular endothelial growth factor without melanocyte cytotoxicity. Furthermore, athermal devices (picosecond 1064 nm) and insulated radiofrequency (RF) micro-needling demonstrated significant efficacy in clearing dermal pigment and repairing basement membrane degradation without triggering thermal spread. These findings confirm that successful management of Fitzpatrick IV–VI requires a multi-layered strategy of cellular modulation, vascular suppression, and dermal-epidermal junction repair. Methods: To arrive at the synthesized data, a comprehensive search was conducted to locate, select, and extract relevant findings from recent clinical protocols and emerging technological studies. This literature was systematically reviewed to evaluate novel therapeutic targets, specifically tailored for Fitzpatrick IV–VI skin. The extraction process prioritized studies addressing epigenetic modification, basement membrane repair, and vascular modulation to ensure a robust comparison against traditional therapies.
Background: Vitiligo is an autoimmune disease characterized by depigmented macules and patches over the skin or mucosa and is of great aesthetic concern. It affects 2% of the world’s population with an average age of 20 years. Lip vitiligo is a distinct focal subtype of vitiligo accounting for 16% of total cases and has a significant impact on life, including lowered self-esteem. Though there are many topical and systemic agents available, it is often resistant to medical treatment, and there is an unmet medical need for novel therapeutic interventions. The aim of this study is to know the efficacy of microneedling with 5-fluorouracil in lip vitiligo. Methods: 25 patients with lip vitiligo were prospectively analyzed for the efficacy of microneedling with 5-fluorouracil, which is done at a 3-week interval for a maximum of six sessions with postprocedure follow-up of 12 weeks. Assessment was done at baseline and thereafter every month using clinical photographs and by subjective assessment score of repigmentation. Results: Out of 25 patients with lip vitiligo, 48% showed excellent response, followed by 24%, 16%, and 12% showing very good, good, and poor response, respectively. The most common side effect noted was pain (80%), followed by oozing and crusting (60%). Conclusion: The integration of microneedling with 5-fluorouracil has emerged as a promising and innovative approach, with reduced side effects and potentially transforming the management of this difficult condition.
Background: Vitiligo is considered the most common acquired pigmentation disorder affecting about 1%–2% of the world’s population; characterized by the development of well-defined depigmented macules on the skin that reflect the loss of epidermal melanocytes. The etiopathology of the disease has not been well defined, but multiple factors contribute to melanocyte loss: autoimmunity, genetic, oxidative stress, and neurological system dysfunction. The majority of diagnostic criteria are based on clinical findings of acquired, clearly defined white lesions on the skin that do not have any associated inflammation and tend to expand centrifugally. Depending on our observation, some hypopigmented and even depigmented lesions may not be easily recognizable or detectable by the naked eye but appear obviously upon examination using Wood’s light. Wood’s light examination becomes essential in such cases for better recognition and definition of the lesions. Aim: The aim of this study was to use Wood’s light for diagnosis of what is termed “Invisible, subclinical or unseen vitiligo” as early detection of such lesions could help in early diagnosis; hence, early intervention. Results: Wood’s light examination revealed areas of hypopigmentation within the area of actual vitiligo lesions which was not seen clinically. Even actual vitiligo lesions’ surface area, as perceived by the dermatologist lesions delineated under Wood’s lamp, were significantly larger than those seen by the naked eye due to the detection of new clinically invisible lesions and/or invisible extensions to clinically visible lesions. These lesions were discovered by the use of Wood’s light (unseen, invisible, or subclinical). Conclusion: Wood’s light should be used for every patient complaining of vitiligo in order to detect the presence of what is called “invisible, subclinical, or unseen vitiligo lesions.” Once we find these lesions, early intervention with proper treatment, especially systemic ones, stops progression and improves outcomes.
Vitiligo is a common depigmentary disorder and is of major social and cosmetic concern. It is an autoimmune disorder characterized by the development of depigmented macules secondary to chronic melanocytic disappearance in the epidermis and hair follicles. The nevus of Ota is a rare congenital dermal melanocytic disorder characterized by bluish-black to grayish-brown diffuse pigmentation of facial skin and mucous membranes in the distribution of the ophthalmic, maxillary, and occasionally the mandibular divisions of the facial nerve . The association of nevus of Ota with vitiligo is a rare amalgamation. Therefore, we report a rare coexistence of vitiligo vulgaris with overlying dermal melanocytosis in a 32-year-old female.
A 10-year-old boy presented with a congenital melanocytic naevus over the right face and neck showing gradual central lightening and surrounding depigmentation over one year. Examination revealed a 7 × 5 cm 2 hyperpigmented plaque with peripheral flat depigmenting areas, grey hair and perifollicular pigmentation. Dermoscopy demonstrated heterogeneous pigment with white structureless areas, while ultraviolet fluorescent dermoscopy highlighted sharp lesion margins. Findings suggested spontaneous regression of CMN with vitiligo-like depigmentation, likely due to immune-mediated melanocyte destruction. Recognition of this benign process is important to distinguish it from melanoma-associated regression and avoid unnecessary interventions, while ensuring appropriate clinical monitoring for atypical changes.
Back Ground: Eruptive hypomelanosis (EH), a novel paraviral exanthem is characterized by the acute onset of asymptomatic hypopigmented macules typically affecting the face and extremities often following a prodromal viral illness in paediatric age group. EH can mimic common hypopigmentary conditions such as pityriasis alba, pityriasis versicolor and progressive macular hypomelanosis leading to misdiagnosis and unnecessary management. Observations: This case series describes 14 paediatric patients with eruptive hypomelanosis, all of whom presented with characterstic uniform clinical presentation. The defining feature was the sudden eruption of multiple, asymptomatic, symmetrical ill-defined hypopigmented macules with fine minimal scaling following a recent febrile or respiratory illness. Three children showed eosinophilia, elevated IgE levels, atopy, and two children had transient lymphadenopathy respectively. In all the cases lesions resolved spontaneously within 2 weeks to 2 months with simple supportive care like emollients and multivitamins. Conclusion and Relevance: Eruptive hypomelanosis is a benign, self-limiting, postviral hypopigmentary eruption in children. Our series emphasizes a unique facial-predominant presentation, expanding the known clinical spectrum of this underrecognized paraviral entity. Awareness of this specific presentation is crucial for clinicians to ensure accurate diagnosis, avoid misidentification as other hypopigmentary disorders, and prevent unnecessary investigations and treatment
Extragenital lichen sclerosus et atrophicus (LSA) is rare in children. We report a 7-year-old girl with multiple whitish, wrinkled, bizarrely shaped plaques over the trunk and legs for two months. Dermoscopy revealed white structure-less areas, follicular plugging, and a comet-tail appearance, consistent with LSA. Topical fluticasone propionate 0.05% cream led to marked improvement. Pediatric extragenital LSA may mimic vitiligo, morphea, and pityriasis alba, often causing diagnostic delays. Early recognition and therapy are important to prevent progression and cosmetic sequelae.
Spitz naevus is a benign melanocytic lesion classically described in children and adolescents. Its occurrence in adults, particularly with atypical clinical features, poses a significant diagnostic challenge as it may closely mimic malignant melanoma. We report a case of a 38-year-old man presenting with a solitary, slowly enlarging hyperpigmented plaque on the forehead. Clinicopathological correlation was essential in establishing the diagnosis. This case highlights the importance of including Spitz naevus in the differential diagnosis of solitary pigmented plaques in the head and neck region of adults.
Lichen planus pigmentosus (LPP) is a chronic, acquired dermal melanosis characterized by slate-gray to brownish-black macules and patches, predominantly affecting individuals with darker skin phototypes. The condition often involves photo-exposed and flexural sites and is associated with significant cosmetic and psychosocial distress. Etiopathogenesis is multifactorial, implicating T-cell–mediated interface dermatitis, ultraviolet and visible light exposure, and contact allergens such as para-phenylenediamine. Management is challenging due to its recalcitrant nature, limited high-quality evidence, and the risk of post-treatment pigmentary alterations. This narrative review synthesizes prospective and interventional studies evaluating current and emerging therapies for LPP. Topical calcineurin inhibitors, particularly tacrolimus 0.03% ointment, have shown moderate to excellent improvement in over half of treated patients without significant adverse effects. Low-dose oral isotretinoin (20 mg/day) demonstrated moderate to good improvement in approximately 78% of cases, with manageable side effects. Oral tranexamic acid (250 mg/day) provided partial improvement and sustained remission in compliant patients, emphasizing the need for thromboembolic risk assessment. Energy-based therapies, notably Q-switched Nd:YAG laser, offer targeted pigment reduction, with high-fluence protocols yielding faster clearance but greater side-effect risk, and low-fluence “laser toning” showing more gradual improvement with better tolerability. Platelet-rich plasma therapy achieved ≥50% clearance in 41.7% of patients in pilot studies, with minimal adverse events. Emerging data suggest Janus kinase (JAK) inhibitors, such as oral tofacitinib, may hold promise in refractory generalized cases. A pragmatic approach involves strict photoprotection, allergen avoidance, and patient counseling, followed by topical therapy for localized disease and systemic agents for extensive or progressive cases. Procedural and regenerative modalities may be considered for refractory disease in experienced hands. Larger randomized controlled trials, standardized outcome measures, and longer follow-up are required to establish optimal treatment protocols for LPP.
Davener’s dermatosis, a rare and often underreported condition, primarily affects individuals who engage in prolonged periods of repetitive motion or pressure against the skin. It usually presents with hyperpigmented patches but can appear as lichenified plaques due to chronic friction. We report a case with frictional hypermelanosis along the spinous processes in a thin-built woman.
Nonpathologic patterns of cutaneous pigmentation are a common concern among individuals with skin of color (SOC). However, many healthcare providers, particularly dermatologists, report having inadequate training in how to recognize and treat the unique cutaneous pigmentation concerns of their patients with SOC. Although variations in physiologic pigmentation are usually benign differences in skin tone arising from increased melanin production, many individuals—particularly those with SOC—may be concerned about the cosmetic appearance of pigmentation variations or feel that they indicate disease. Therefore, the ability to recognize and differentiate benign versus pathologic physiologic pigmentation is crucial for dermatologists to avoid unnecessary diagnostic tests and treatments and to provide accurate, equitable, and patient-centered care to patients with SOC. In this narrative review, we summarize the most common patterns of benign physiologic pigmentation seen in the skin, nails, and oral and genital mucosa that may be of particular concern for patients with SOC. Our aim is to provide clinicians with a comprehensive overview of benign physiologic pigmentation patterns to prevent misinterpretation of these normal findings as pathologic.
Melanoma represents a malignant tumor that arises from melanocytes. Due to its metastatic potential, melanoma leads to >90% of skin cancer-related deaths. It develops primarily in Caucasian populations, with its incidence remaining very low among darkly pigmented populations of African, Asian, and Hispanic origin. We report a case of melanoma presenting as a chronic nonhealing ulcer in an elderly diabetic female.
Background:Topical steroid-dependent face (TSDF) is a concerning issue in India, due to the unrestricted availability of topical steroid-containing products over-the-counter. The prevalence of TSDF in India may be indicative of an unspoken obsession with fairness that is still rampant in our society. Managing this condition is a significant challenge for dermatologists. Aims: The aim of the study was to evaluate patients who misused topical steroids to achieve fairer skin, clinically as well as by dermoscopy, And to characterize the dermoscopic features of TSDF and to correlate them with clinical findings. Methods: A cross-sectional, observational study was conducted among 50 patients presenting with TSDF, who attended the dermatology outpatient department of our institute, after obtaining approval from the institutional ethics committee. Patients aged 11 years and above, of either gender, were included. Patients using topical corticosteroids for a known disease where it is indicated and with comorbidities with cutaneous changes that could mimic TSDF were excluded. Results: Out of 50 patients, 13 were males and 37 females. Erythema was the most common morphology (88%). The most common dermoscopic feature was diffuse red areas (98%) followed by telangiectasia (96%). Limitations: Lack of histopathological correlation is the limitation of our study. Conclusion: Obsession with fairness prevalent in our society leads to the use of unscrupulous means to attain it, like irrational use of topical corticosteroids. This can lead to an alarming entity known as TSDF. Dermoscopy can act as a contemporary instrument for the early detection of TSDF and is helpful for patient education.
Context: Lip hyperpigmentation poses a significant concern for many patients due to its impact on aesthetics and cosmetic appearance. It remains a challenging condition to address, with limited treatment options available, each varying in efficacy. Aims: The aim of this study was to assess the effectiveness of diode laser technology in treating lip hyperpigmentation. Methods and Material: Patients with physiological lip hyperpigmentation, who had previously shown no response to other treatment modalities, were recruited for the study. Statistical Analysis Used: The Statistical Package for the Social Sciences (SPSS) software program was used. The grades of pigmentation before and after treatment were subjected to the Wilcoxon signed ranks test. A value of p < 0.05 was considered statistically significant. Results: Twelve patients participated in the study. A diode laser session was planned at baseline and then at every 2-month interval. Monthly follow-ups through serial photography were done, and the response was evaluated by a reduction in darkness and pigmentation by a special grading system at baseline and at the end of 6 months. More than 90% of the patients had a good to excellent response at the end of 6 months with a significant p-value (<0.05). Conclusions: Diode laser therapy can be considered a safe and efficacious option for managing lip hyperpigmentation, which is unresponsive to traditional treatments.
