A Case of Xeroderma Pigmentosum

Abstract

The role of the immune system in pathogenesis of skin cancer has been attracted increasing attention in recent years. Some limited studies and observations suggest that altered immune status may be a factor in the initiation and growth of cutaneous malignancies. Authors experienced a typical case of xeroderma pigmentosum in a 6 year-old girl, who has been suffered from hyper and hypopigmented macules on sun-exposed area, photophobia and also noted eroded lesion on the lower lip. The biopsy finding of the hyperpigmented macule showed that of freckle and the finding of actinic cheilitis was observed from the specimen of eroded 1esion on the lower lip. We performed immunologic test and obtained some evidences of immunologic defect; such as decreased numbers of total T cells, T-suppressor cell and B cell in our patient.
