A Case of Multiple Tiny Osteolipomas on Face.

male population should be distinguished from primary histiocytoid (apocrine) carcinoma of the skin, a rare neoplasm that generally affects elderly men, typically occurring on the eyelid or on the axilla.9,10 Primary cutaneous histiocytoid carcinoma exhibits histiocytoid or signet-ring cell cytology with apocrine differentiation, similar to LBC.9 Notwithstanding, most cases of histiocytoid carcinoma of the skin will stain positive with p63, supporting a primary cutaneous origin; in addition, expression of E-cadherin is usually retained in histiocytoid carcinoma of the skin, as well as in other apocrine carcinomas.9,10 PLBC should be also distinguished from metastases of signet-ring carcinomas from other primary sites (including the stomach), sclerosing epithelioid fibrosarcoma, myeloid sarcoma, and plasma cell dyscrasias.11 Ascertainment of the CK-7(+) CK20(2) ER (+) immunophenotype will be decisive in rendering a diagnosis of PLBC. In sum, we reported the exceptional occurrence of cutaneous involvement by PLBC in a male patient; IHC staining for E-cadherin is essential for proper diagnostic framing.
