    Area of Science:

    • Dermatology
    • Oncology

    Background:

    • Keratoacanthoma is a common, benign skin tumor originating from hair follicles.
    • Predominantly affects sun-exposed skin in the elderly, with 80% occurring on the face.

    Observation:

    • Characterized by rapid growth of a painless, dome-shaped lesion with a central keratin plug.
    • Undergoes spontaneous involution over 6-12 months, leaving a scar.

    Findings:

    • Histologic features can mimic squamous cell carcinoma, necessitating careful evaluation.
    • While typically benign, complete regression is not guaranteed, and malignant transformation is reported.

    Implications:

    • Excisional biopsy is the recommended management for definitive diagnosis and optimal prognosis.
    • Surgical closure techniques like local flaps or grafts provide superior cosmetic results.
