Epidermolytic Acanthoma on Fingers, Mimicking Flat Warts

Area of Science:

• Dermatology
• Histopathology

Background:

• Epidermolytic acanthoma (EA) is a benign skin condition characterized by specific histological features.
• It commonly affects the trunk, face, and genitoscrotal regions.

Observation:

• A novel case of epidermolytic acanthoma was observed.
• The presentation involved the palmar area and fingers, which is an unusual location for this condition.

Findings:

• Histological examination confirmed epidermolytic hyperkeratosis, consistent with EA.
• The clinical presentation and location were atypical for previously reported cases.

Implications:

• This case expands the known clinical spectrum of epidermolytic acanthoma.
• It highlights the importance of considering EA in the differential diagnosis of palmar lesions.
