The case herein reported is interesting because of the rarity of cancerous metastases to the scalp and because of their striking similarity to turban tumors (figs. 1 and 2). The rapidity of the development of the condition, which was the most important factor in the clinical diagnosis, was overlooked because of the decided resemblance, and the correct diagnosis of metastases was made only at the autopsy table.
Turban tumors is a short clinical name which designates a variety of slow-growing nonkeratinizing or basal cell epithelioma. It is characterized by multiple tumors varying in size from that of a pinhead to that of a pigeon's egg or larger and numbering from a few to hundreds. The tumors are usually confined to the scalp and are grouped in bunches, sometimes covering the entire scalp like a turban. The condition may be considered as an ultimate stage of adenoma sebaceum and epithelioma adenoides
