Mosaic acral keratosis
Clinical and Experimental Dermatology
|September 1, 1990
Summary
Two patients presented with a unique mosaic pattern of acral keratosis on their feet and legs. This condition also involved palmoplantar keratosis and specific joint lesions, prompting a discussion on differential diagnoses.
Area of Science:
- Dermatology
- Medical Genetics
Background:
- Acral keratoses encompass a spectrum of conditions affecting the distal extremities.
- Understanding rare presentations is crucial for accurate diagnosis and management.
Observation:
- Two patients exhibited a distinctive mosaic or jigsaw-puzzle pattern of keratotic papules on the dorsal feet and legs.
- Associated findings included diffuse palmoplantar keratosis, clavus-like lesions on toe joints, and in one case, hand papules and knee plaques.
Findings:
- The described acral keratosis presents with a unique patterned distribution.
- Clinical presentation varied slightly, including involvement of hands and knees in one patient.
Implications:
- This case highlights the importance of recognizing diverse patterns of acral keratosis.
- Further research into the etiology and specific subtypes of these patterned keratoses is warranted.
- Accurate differential diagnosis is essential for appropriate patient care.
