[Palmoplantar epidermal cyst]
Summary
Epidermal cysts on the palms and soles are uncommon skin growths. These rare cysts result from the epidermis being pushed into deeper skin layers, often due to injury.
Area of Science:
- Dermatology
- Pathology
Context:
- Epidermal cysts are typically found on the face and trunk.
- Cysts on the palms and soles are exceptionally rare presentations.
Purpose:
- To report on three rare cases of epidermal cysts occurring on the palms and soles of the feet.
- To highlight the etiology and clinical presentation of these unusual lesions.
Summary:
- Three cases of epidermal cysts were documented: one on the palm and two on the sole of the feet.
- These cysts arose from traumatic implantation of epidermal elements into the dermis or subcutis.
Impact:
- This case series expands the known anatomical distribution of epidermal cysts.
- It may aid clinicians in recognizing and managing these rare presentations on the extremities.
