Basel - Dermatology Abstract 155, Vol. Histologic examination revealed a basal cell carcinoma, a syringocystadenoma papilliferum and a proliferating trichilemmal cyst.
Sebaceous nevus has a well-documented neoplastic potential.
Multiple tumors may occasionally arise, but the coexistence of 3 or more tumors is extremely rare. Close monitoring and early complete surgical excision of sebaceous nevi are warranted, in order to ensure a favorable prognosis.
