Systematized keratotic nevus with finger contracture

Area of Science:

• Dermatology
• Plastic Surgery
• Medical Case Reports

Background:

• Epidermal nevi are benign congenital skin tumors.
• Systematized keratotic nevus is a rare variant characterized by warty or horny papules.
• Congenital anomalies affecting limb function are uncommon presentations of epidermal nevi.

Observation:

• A rare case of systematized keratotic nevus involving the upper limb is presented.
• The nevus extended from the fingers to the elbow, exhibiting mixed clinical and histological features.
• Significant dysfunction, specifically incomplete finger flexion, was observed due to the extensive nevus.

Findings:

• The case highlights a rare association between systematized keratotic nevus and functional impairment of the hand.
• Histopathological examination confirmed mixed epidermal changes consistent with this rare nevus subtype.
• Surgical management involved a full-thickness skin graft to address the affected area.

Implications:

• This case expands the understanding of the clinical spectrum and potential complications of systematized keratotic nevus.
• It underscores the importance of considering functional deficits in the management of extensive epidermal nevi.
• Successful surgical intervention demonstrates a viable treatment option for improving both cosmetic and functional outcomes.
