We report a case of xeroderma pigmentosum in a 9-year-old back Cameroonian boy. The diagnosis was based on typical clinical presentation of the disease: cutaneous atrophy, hypepigmented macules, and areas of depigmentation on sun exposed regions of the skin. Multiple tumoral lesions were localized on the head. Ocular findings were also present: conjunctival hyperemia, peripheral corneal opacification. Excision of the tumors and potoprotection was proposed for this patient. The role of tribal black African marriage traditions in disease transmission is discussed.
