CUTANEOUS EPITHELIOID HEMANGIOENDOTHELIOMA, EPITHELIOID CELL HISTIOCYTOMA AND SPITZ NEVUS - 3 SEPARATE EPITHELIOID TUMORS IN ONE PATIENT

We report the unusual history of a young lady who, over a period of 9 years, developed 3 epithelioid neoplasms of different histiogenetic or igin: a cutaneous epithelioid hemangioendothelioma, an epithelioid cel l histiocytoma, and a Spitz nevus. To the best of our knowledge, such an unusual combination of neoplasms has not been reported previously a nd raises the question of an underlying ''epithelioid'' reaction patte rn responsible for the epithelioid appearance in all 3 tumors; the lik elihood of such a combination of tumors occurring in a single patient would be less than 1 in 1 billion.
