Area of Science:

  • Genetics
  • Dermatology
  • Epidemiology

Context:

  • Mal de Meleda is a rare autosomal recessive palmoplantar keratoderma.
  • Consanguinity in certain regions contributes to its higher prevalence.
  • Understanding its genetic basis and clinical spectrum is crucial for diagnosis.

Purpose:

  • To describe the epidemiological, clinical, and progressive aspects of Mal de Meleda.
  • To analyze the disease in 16 patients from a large consanguineous Tunisian family.
  • To differentiate Mal de Meleda from other inherited palmoplantar keratodermas.

Summary:

  • The study observed 16 patients (9 male, 7 female) aged 3-90 years with Mal de Meleda.
  • Onset in infancy featured palmar/plantar erythema and hyperkeratosis, progressing to dorsal involvement and finger contractures in adulthood.
  • Associated symptoms included hyperhidrosis, fetid odor, and conical distal phalanges.

Impact:

  • This research enhances the understanding of Mal de Meleda's clinical variability and progression.
  • It emphasizes the importance of considering consanguinity in disease prevalence.
  • Accurate differentiation from similar conditions like Papillon-Lefévre syndrome is vital for patient management.
