Abstract:
Primary amelanotic melanoma is an infrequent occurrence in the oral cavity. Owing to the high rate of local invasion and distant metastasis, oral amelanotic melanoma (OAM) carries a very poor prognosis. The absence of pathognomonic clinical and routine histological features in OAM is the reason for diagnosticdelay, which further worsens the prognosis. This case report discusses the masquerading nature of OAM that was clinically and histologically mimicking several malignant neoplasms. This case also demonstrates the poor prognosis of OAM. The objective of presenting this case is that the diagnostic delay of OAM can be avoided through enhanced clinical awareness and subsequent appropriate immunohistochemical investigations, in addition to the routine H&E-stained histopathological evaluation.
