This study reports a rare inherited skin condition, palmoplantar keratoderma with amyotrophy, observed in a South African family. The condition, characterized by thickened hand/foot skin and muscle wasting, appears to be autosomal dominant.

Area of Science:

  • Genetics
  • Dermatology
  • Neurology

Background:

  • Palmoplantar keratoderma is a group of inherited skin disorders characterized by thickening of the skin on the palms and soles.
  • Amyotrophy refers to muscle wasting or thinning.

Observation:

  • A South African Black family presented with palmoplantar keratoderma and amyotrophy.
  • Neuromuscular defects were absent; muscle thinning was attributed to disuse atrophy.
  • Additional features included volar hyperhidrosis, nail abnormalities, and knuckle pads in some individuals.

Findings:

  • The described syndrome, palmoplantar keratoderma with amyotrophy, appears to be inherited as an autosomal dominant trait.
  • This specific combination of symptoms and inheritance pattern has not been previously reported in medical literature.

Implications:

  • This report expands the known spectrum of inherited palmoplantar keratoderma syndromes.
  • Further research may elucidate the specific genetic mutation responsible for this unique condition.
  • Recognition of this syndrome is crucial for accurate diagnosis and genetic counseling.
