Abstract
We report a case of desmoplastic malignant melanoma. A 66-year-old man had a pigmented spot on his right cheek.
He had noticed a black nodule which grew gradually on the surface of the spot since April in 2004, the nodule was excised, and its histopathological examination showed proliferation of amelanotic spindle-shaped cells with desmoplasia. On immunohistological examination S-100 and Vimentin stains were positive, while HMB-45 stain was negative. Based on these findings, we diagnosed this tumor as desmoplastic malignant melanoma.
