Abstract

— Giant cell dermatosisis is reported in six cats with evidence of concurrent feline leukemia virus (FeLV) infection. Scaling, crusting and alopecia, accompanied by pruritus, affected the head and/or face predominantly in most cats; generalized skin disease developed in one cat. Histologically, giant keratinocytes resembling syncytial cells were found in the epidermis and superficial hair follicles, and were accompanied by dyskeratosis, pustules and ulcers. Immunohistochemical staining revealed FeLV antigen in the giant cells and adjacent keratinocytes. FeLV infection may have led to neoplastic alteration of the keratinocytes through recombination with host oncogenes Resumen Este articulo se basa en seis gatos con dermatosis de las celulas gigantes infectados con el virus FeLV. Estos animales presentaban escamas y costras, asi como perdida de pelo y picor en las regiones de la cabera y cara, predominantemente. Tan solo uno de los gatos desarrollo una dermatosis generalizada. En el examen histologico se demostro la presencia de keratinocitos gigantes con semejonza a las celulas sinticiales localizados en la epidermis y foliculos pilosos superficiales, acompanados de disqueratosis, pustulas y ulceras. Las finturas histo-inmunologicas demostraron el antigeno FeLV en las celulas gigantes y keratinocitos adyacentes. La injeccion con el virus FeLV pudo haber conducido a la alteracion neoplastica de los keratinocitos a traves de la recombinacion con los oncogenes del hospedador.
