Pityriasis rotunda, a rare skin condition, presents as circular, scaling patches. This study identifies three cases in a Sardinian family, suggesting a potential ethnic predisposition and association with favism.

Area of Science:

  • Dermatology
  • Clinical Genetics

Background:

  • Pityriasis rotunda is a rare dermatosis typically observed in individuals of Japanese and Black descent.
  • Characterized by asymptomatic, circular, dusty scaling and dyschromic patches.

Observation:

  • Three cases of pityriasis rotunda were identified within a Sardinian family.
  • The affected individuals were in good health.
  • A notable association with favism was observed in the family.

Findings:

  • The familial occurrence suggests a potential genetic component or ethnic predisposition in Sardinia.
  • The co-occurrence with favism warrants further investigation into shared genetic or environmental factors.

Implications:

  • This report expands the known demographic distribution of pityriasis rotunda.

  • Sardinia may represent an ethnic center for this condition, possibly linked to favism.
  • Further research is needed to elucidate the etiology and genetic underpinnings of pityriasis rotunda.
