Olmsted Syndrome—Palmoplantar and Periorificial Keratodermas: Association with Malignant Melanoma

Background:

Olmsted syndrome is a rare congenital disorder with mutilating palmoplantar keratoderma, periorificial keratotic plaques, and other variable features.

Objective:

We describe a 65-year-old woman with Olmsted syndrome complicated by the occurrence of a malignant melanoma inside the plantar keratoderma. To our knowledge, this is the first reported case of such an occurrence in Olmsted syndrome. The published cases of this rare disorder are reviewed.

Conclusion:

An association between malignant epithelial tumors and Olmsted syndrome has already been reported. The association of malignant melanoma with other types of palmoplantar keratodermas has been reported. This may suggest a predisposition to melanocytic as well as squamous cell malignancies in congenital keratodermas. Oral retinoids appear to be the most promising treatment for Olmsted syndrome and for other symptomatic keratodermas.

Olmsted syndrome: report of a new case with unusual features

Olmsted syndrome is a rare disorder characterized by the combination of periorificial keratotic plaques and bilateral palmoplantar keratoderma. New associated features continue to be reported. Olmsted syndrome in a female patient is particularly rare, and we report such a case having a haemangioma in addition to other features of the syndrome.

Olmsted syndrome: the clinical spectrum of mutilating palmoplantar keratoderma

Olmsted syndrome is a rare variety of transgredient palmoplantar keratoderma with an undefined inheritance pattern. It starts in the neonatal period or in childhood and has a progressive and extremely disabling course. We report two new, unrelated patients with Olmsted syndrome, one with the early signs and symptoms of the disorder, the other showing the full-blown spectrum of the syndrome during a 30-year follow-up period.
