Acupuncture-exacerbated Pyoderma Gangrenosum Associated With IgG Multiple Myeloma br

Introduction. PG is an uncommon, noninfectious neutrophilic dermatosis. Very few cases of bullous PG as the first manifestation of IgG myeloma have been reported. HE4, a novel marker for human cancers, may be a promising marker of bone destruction and disease progression in patients with hematologic malignancies and PG lesions. Case Report. The authors report a case of a 49-year-old female who presented with painful patches located on the lower extremities for the past 5 months, and then had lesions that rapidly progressed to necrotic ulcers after unregulated acupuncture therapy. During the treatment procedure, underlying IgG Kappa-type myeloma was diagnosed. After the diagnosis was confirmed, the patient underwent chemotherapy, and the lesions started to heal and gradually showed scarring. The current report also discusses the potential value of HE4 as applied to malignancies that present with PG and bone destruction. Conclusions.Once the diagnosis of the underlying systemic disease is confirmed, patients with PG should simultaneously receive aggressive treatment for the primary disease. More emphasis should be put on HE4 regarding the progression of monoclonal gammopathy-related PG with bone destruction to provide new ideas to understand the pathogenesis of this disease.
