Apparently Primitive Caecal Malignant Melanoma: A Diagnostic and Histogenetic Challenge: A Case Report and Literature Review

Abstract

Marcello Filotico* and Giuseppe Albonico

Extracutaneous melanomas are in the majority of cases reported in the literature as secondary lesions of a primary skin tumor. Far more rarely do they present themselves as primitive. Extracutaneous melanomas can be grouped into three categories: Ocular; Mucosal, Metastatic. Obviously, the greatest number of lesions is represented by metastatic forms. The Mucosal Melanomas preferably arise in peripheral districts of the gastrointestinal tract (mouth, pharynx, esophagus, anorectal mucosa), respiratory (nose, larynx) and urogenital (Vulva, vagina, cervix).
