    Area of Science:

    • Dermatology
    • Pathology

    Background:

    • Subungual lesions can present with diverse etiologies, necessitating accurate diagnosis.
    • Epidermal cysts are common benign skin tumors, but their occurrence under the nail is less frequent.

    Observation:

    • A patient presented with a painful lesion beneath the fingernail (subungual).
    • Biopsy confirmed the subungual lesion to be an epidermal cyst.

    Findings:

    • Subungual epidermal cysts are typically asymptomatic.
    • The pathogenesis and incidence of these cysts are reviewed in the literature.

    Implications:

    • Clinicians should include epidermal cysts in the differential diagnosis for painful subungual lesions.
    • Recognition of this entity can prevent misdiagnosis and guide appropriate management.
