Abstract
|
|
|
Sebaceous carcinoma (SC) is a slow-growing, locally aggressive tumor with the high potency of metastatic spread.
This neoplasm frequently arises from the sebaceous glands of the eyelid and exceptionally from extraocular sites.
Approximately one-quarter of all reported cases of SC are extraocular. We observed a 42-year-old woman with an
crusted erythematous to brownish plaque on her scalp. The biopsy specimen showed that multiple lobules were
composed of foamy-cytoplasmic cells and sebocytes which show pleomorphism and atypia. For the immunohistochemistry, abundant tumor cells (with the expressions of epithelial membrane antigens and cytokeratin) were found within the masses. We present here a case of SC of the scalp arising from a previous lesion clinically compatible
with a nevus sebaceous
