Desmoplastic malignant melanoma is an unusual variant of cutaneous melanoma. Arising from either an occult or recognized superficial melanotic lesion, it evolves into an aggressive, locally recurrent and frequently metastasizing, deep, hard, fibrous tumefaction. A highly confusing clinical and histologic picture makes accurate diagnosis especially difficult. Appropriate treatment is often delayed until time of recurrence. Prognosis is invariably poor if the tumor is not adequately treated primarily. Close follow-up is essential. Since its original description by Conley et al. in 1971, in which 7 cases were presented, fewer than 150 additional cases have been cited. We provide a detailed report of 11 cases of this distinct histopathologic entity. Clinical course, histopathology, surgical management, and prognosis are discussed. It is our hope that this comprehensive review will instill a high index of suspicion among surgeon and pathologist alike, enabling earlier diagnosis and definitive therapy.

D008545	Melanoma	A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D009364	Neoplasm Recurrence, Local	The local recurrence of a neoplasm following treatment.

D009418	S100 Proteins	A family of highly acidic calcium-binding proteins found in large concentration in the brain and believed to be glial in origin. They are also found in other organs in the body. They have in common the EF-hand motif (EF HAND MOTIFS) found on a number of calcium binding proteins. The name of this family derives from the property of being soluble in a 100% saturated ammonium sulfate solution.
