Maxillary sinus hypoplasia is a relatively uncommon clinical condition that may be misdiagnosed as chronic sinusitis or neoplasm by otolaryngologist. We report an unilateral clinical case of this entity confirmed by CT and a short literature review is performed at this respect.
Mucosal melanomas of the nasal cavity and paranasal sinuses are rare and agresive neoplasms and carries a bad prognosis. The diagnosis may require confirmatory immunohistochemical stains (S-100 protein, HMB-45, vimentin and cytokeratine). The clinical records of 6 patients with the diagnosis of sinonasal melanomas between 1991 and 2005 were retrospectively reviewed. The mean age was 70 years (range 51 to 83 years), there were 2 men and 4 women. Surgery was performed in four patients, adjuvant radiation therapy was used in one patient after local recurrence and chemotherapy in three patients. Three of four patients (75%) had a recurrence after previous treatment (surgery). The actuarial disease-free survival for this group of 6 is 33.3% (2 of 6). Mucosal melanoma of the head and neck remains a difficult disease to treat, with high locoregional recurrence rates and poor prognosis.
Maxillary sinus hypoplasia is a common condition that may be misdiagnosed as chronic sinusitis. Although hypoplasia can usually be seen on conventional sinus films, computed tomography may be necessary, as in the cases described by the authors in this article.
We denominate otohematoma to the blood stock in the pinna. It occurs by the broke of pinna drilling vessels. Its origin is traumatic. It is usual after soft but continuous hits, less often after hard and unique ones, and more less often bilateral forms like the case we present.
Paragangliomas are tumours derived from cells in the neural crest that are normally benign, and have low incidence and slow growth rates. We report the clinical case of a 61 year-old female studied at the ENT's surgery suffering from a left side tinnitus with four years of evolution. Complementary explorations were carried out such as an audiogram, computerised axial tomography scans and angioresonance. In spite of the high diagnosis suspection, it is late confirmed, because it was not visible in the radiographic studies. We revised the literature referring this pathology.
