Nevus sebaceus of Jadassohn
Pronunciation: NEE-vəs sə-BAY-shəs of jah-DAH-sohn
Congenital hairless, yellow-orange plaque typically on the scalp that may develop secondary neoplasms during adolescence.
Full Definition
Nevus sebaceus of Jadassohn is a congenital organoid nevus composed of malformed hair follicles, sebaceous glands, and apocrine glands. It appears as a well-demarcated, hairless, yellow to orange plaque most commonly on the scalp or face. The lesion undergoes characteristic changes at puberty due to hormonal stimulation and has a risk of developing secondary benign and malignant neoplasms, particularly trichoblastoma and basal cell carcinoma.
