Exacerbation of the lesions during treatment with topical corticosteroids prompted a search for an infectious cause, which proved to be syphilis in the tertiary stage. The clinician should maintain(More)

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(More)
