Nevus sebaceous and syringocystadenoma papilliferum

A 52-year-old patient was admitted to the hosptial for evaluation of hypertension. He had two skin lesions, one on the forehead and one in the postauricular area, which had been present since birth. The forehead lesion was a nevus sebaceous and the postauricular lesion was a syringocystadenoma papilliferum. Except for a few patients with widespread nevus sebaceous and syringocystadenoma papilliferum associated with neurologic abnormalities, most of the previously reported patients with these nevi have had solitary lesions of one or the other. An association of nevus sebaceous and syringocystadenoma papilliferum in the same lesion is not uncommon. Despite bleeding and crusting in one of the lesions and despite informing the patient that a malignant neoplasm may develop in these nevi, he refused excision of either of the lesions.
