Xeroderma pigmentosum is an uncommon inherited autosomal recessive disorder. Affected patients have a 2000-fold amplified risk of skin cancer. There is an inability to repair the damage to genetic material caused by ultraviolet light. Basal cell carcinoma is the most commonly associated carcinoma followed by squamous cell carcinoma and melanoma. It is a highly mutilating disorder where occurrence of multiple cancers and repeated surgical treatments result in serious psycho-social implications. We present a case of diagnosed xeroderma pigmentosum in a 25 year old male who presented with multiple lesions and non-healing ulcers on face. Four surgical specimens from left lower eyelid, chin, right cheek and upper lip were taken for histopathological diagnosis. Microscopic examination revealed five different tumors from biopsies of these sites - specimen from right cheek revealed two morphologically distinct tumors. The tumors include basosquamous carcinoma, nodular basal cell carcinoma, adenoid basal cell carcinoma, malignant melanoma and cavernous hemangioma.
