A Case of Sebaceous Adenoma

ABSTRACT

We report an uncommon case of sebaceous adenoma in a 36-year-old male who had a solitary, well-de6ned, 0.5×0.8cm sized, round, erythematous nodule on the right side of his forehead. Microscopically, the nodule was composed of poorly developed sebaceous lobules that were irregular in size and shape in the deep reticular dermis. The lobules were composed of mature sebaceous cells in the center and undifferentiated basaloid cells at the periphery. In most lobules, the two types of cells occured in approximately equal proportions. We excised the lesion completely and no evidence of recurrence was observed for 2 years.
