[Florid oral papillomatosis. A contribution to cytostatic therapy].

Based on the recent clinical experience in treating florid oral papillomatosis (FOP), the only successful therapy appears to be the use of cytostatic agents. The case report of a patient with clinically and histologically confirmed FOP is described to emphasize the advantages of administering Bleomycin intra-arterially (external carotid artery) by means of a Holter catheter. This catheter is used to release pressure in the treatment of internal hydrocephalus and is designed to remain in place for a number of years. The successful treatment of FOP points out the possibility of employing a Holter catheter for administering cytostatic agents in the treatment of malignant neoplasms in the facial area. Cytophotometric examinations of the prickle cells within the FOP mass showed a diploid pattern of DNA distribution similar to that of benigh tumors. However, it is not possible to definitely establish the malignant or benign nature of FOP in this manner.
