SEBACEOUS NEOPLASM WITH RETICULATED AND CRIBRIFORM FEATURES - A RARE VARIANT OF SEBACEOMA

Troy and Ackerman defined the term sebaceoma (Am J Dermatopathol 1984: 6: 7-13) as benign neoplasm of basaloid cells with varying numbers of mature sebocytes. Steffen and Ackerman (Neoplasms with sebaceous diff erentiation. Philadelphia: Lee and Febiger, 1994: 401-425) illustrated many examples of sebaceoma, two of which had a reticulated and cribri form pattern. We report a case of sebaceoma from the scalp of a 52-yea r-old white female. Histologically, it displayed reticulated and cribr iform basaloid epithelial islands. This is the third reported case of sebaceoma, to our knowledge, with these unusual features. (C) Munksgaa rd 1998.
