Abstract :

Sebaceous nevus is an epidermal appendageal tumour, histologically composed of acanthosis, papillomatosis, and a hamartomatous conglomerate of large sebaceous glands. Defective hair structures consisting of dilated, keratin filled infundibula showing multiple buds of undifferentiated cells are a prominent feature. Sebaceous nevi are known to be associated with secondary benign adnexal tumours such as trichoblastoma, syringocystadenomapapilliferum, and eccrineporoma, but their association with malignant cutaneous neoplasms such as basal cell carcinoma and especially squamous cell carcinoma is rare. Here we report two such cases.
