So-called "turban tumors" of the scalp are exceedingly rare. Isolated case reports1-5 suggest the infrequency of occurrence of these lesions of the scalp. These tumors of the skin occur on the head and neck, but more frequently involve the scalp.6 Such benign epithelial tumors are observed more commonly in adult life than in childhood. There may be a family history of these tumefactions.7 They may become lobulated and may increase in number and size to such an extent as to cover the entire scalp, giving the appearance of a turban. Such a case was reported in 1951 by Goldman,8 who described the dermatological aspects of a massive turban tumor, which not only completely involved the scalp, but also portions of the face. Surgical treatment consisted of total excision of the scalp and the affected parts of the face and application of skin grafts for restoration.
