Abstract
- Nevus sebaceus is a congenital cutaneous hamartoma which has a potential to develop both benign and malignant neoplasms in late life. One of the benign neoplasms is sebaceous epithelioma that is developed secondarily in lesions of nevus sebaceus. We have experienced a case of sebaceous epithelioma associated with nevus sebaceus in a 54-year-old male. Two nodular tumors developed on the verrucous surfaced yellowish plaque on the scalp. Histopathologic examination revealed mature sebaceous glands in the upper dermis and ectopic apocrine glands in the lower dermis on the verrucous surfaced yellowish plaque, and undifferentiated basaloid cells which were arranged in a palisading pattern at the periphery and groups of mature sebaceous cells on the two nodular tumors. We report a case of sebaceous epithelioma arising from nevus sebaceus.
