Abstract
In a mature ovarian cystic teratoma (MOCT) in a 67-year-old woman we found associated invasive squamous cell carcinoma and nodular amelanotic malignant melanoma. The finding of foci of typical and atypical melanocytic proliferation at the junctional level of the dermal component together with the absence of other possible sources supports an ovarian origin of the melanoma. A comparative analysis of the reported MOCT-associated malignant melanomas emphasizes the singularity of our case in the amelanotic character of the melanoma, its lymphotropism and the coexistence of invasive squamous cell carcinoma.
