[Multiple cutaneous neoplasms following repeated fluoroscopic examinations. (A case of clear-cell malignant hidradenoma associated with intra-epidermal epitheliomas of the Bowen type)].

A case of some neoplastic lesions of the skin of the back, arisen on undamaged skin, in a patient who underwent therapeutic pneumothorax and was submitted to several fluoroscopic examinations for pulmonary tuberculosis many years ago, is reported and discussed. An attempt of evaluation of the exposure to the ionizing radiations received by the interscapular region of the patient is made. The malignant clear-cell hidradenoma is a very rarely observed carcinoma: nine cases have been so far described.
