A Case of Amelanotic Malignant Melanoma of the Maxillary Sinus Presented with Intraoral Extension
Singhvi, Abhishek & Joshi, Ashish
Abstract
Melanoma of the sinonasal cavity has a high incidence of amelanotic presentation. Its
diagnosis is difficult for clinicians and pathologists because of its hidden location and lack of
pigmentation at the microscopic level. We reported a case of amelanotic melanoma of the maxillary
sinus that showed aggressive extension to the oral cavity after extraction of the maxillary tooth.
Histologically, the lesion resembled a plasmacytoid tumour. Diagnosis was made through the
positive immunohistochemical staining for S100 and HMB-45.
