Xeroderma pigmentosurn is a photosensitive hereditary disorder and especially rare in Korea. A 30-year old male patient had been suffered from walnut sized tumor and several ulcerated papules on the face, and scattered brownish macules on the sun-exposed area. Clinical features and histopathologic findings were consistent with malignant malanoma and basal cell epithelioma developing in a xeroderma pigmentosum respectively. Malignant melanoma was surgically excised.
