With demonstration of these two cases and references of few other reported cases we raise the possibility of existence of trichoblastic carcinoma that is distinct from basal cell carcinoma.

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 differentiation. Philadelphia: Lee and Febiger, 1994: 401-425) illustrated many examples of sebaceoma, two of which had a reticulated and cribriform pattern. We report a case of sebaceoma from the scalp of a 52-year-old white female. Histologically, it displayed reticulated and cribriform basaloid epithelial islands. This is the third reported case of sebaceoma, to our knowledge, with these unusual features.
