International Journal of Dermatology
|March 1, 1984
Summary
This study identifies a rare genetic skin disorder, Vohwinkel syndrome, in a father and his two daughters. The patients exhibit severe palm and sole keratoderma and constrictions of the fifth toes.
Area of Science:
- Dermatology
- Medical Genetics
- Human Pathology
Background:
- Familial hyperkeratosis encompasses a group of inherited disorders characterized by abnormal thickening of the skin.
- Vohwinkel syndrome, a rare subtype, presents with distinct palmoplantar keratoderma and constrictions.
Observation:
- A 35-year-old African American male and his two daughters presented with severe keratoderma on palms and soles.
- Two of the three patients displayed ainhum-like constrictions affecting the fifth toes.
Findings:
- The clinical presentation in these patients aligns most closely with Vohwinkel's keratoma hereditarium mutilans.
- This diagnosis is supported by the characteristic dermatologic manifestations observed across affected family members.
Implications:
- Accurate diagnosis of Vohwinkel syndrome is crucial for appropriate patient management and genetic counseling.
- Further research into the genetic basis of this rare condition can improve understanding of keratinization disorders.
