Olmsted syndrome

Olmsted syndrome

(ōlm'sted),
congenital palmar, plantar, and periorificial keratoderma leading to flexion contractures and digital spontaneous amputation.

Olmsted syndrome

A rare congenital disorder (OMIM:614594) characterised by bilateral mutilating palmoplantar keratoderma and periorificial keratotic plaques with severe pruritus, variably accompanied by diffuse alopecia, constriction of digits (which may progress to autoamputation of fingers and toes), onychodystrophy, infections, and squamous cell carcinomas arising on the keratotic areas.

Molecular pathology
Defects in TPRV3, which encodes a nonselective cation channels involved in vasoregulation and temperature sensation, cause Olmsted syndrome.
