This is demonstrated by a case history of a patient with this lesion on the lower lid, which has not been previously described in the British ophthalmological literature. The lesion often presents considerable problems of histological diagnosis.

متن کاملDesmoplastic melanoma: comparison of expression of differentiation antigens and cancer testis antigens.
Desmoplastic melanoma is a diagnostic and therapeutic challenge. Immunohistochemical analysis with antibodies to melanoma antigens can complement morphologic evaluation. Although staining for S100 protein is generally positive, staining for other melanoma differentiation antigens, particularly gp100, Melan-A/MART1 and tyrosinase, is often negative despite being commonly positive in other melano...
