[Carcinoid papillomatosis].

Papilomatosis Carcinoides, presents clinical and histological characteristics that may be authentically described as a transition state between the benign papillomatous proliferations and spindle cell carcinoma. It involves a series of clinical conditions, that are described with different names that correspond to the condyloma accuminatum gigantum. [Buschke and Lowenstein) wartic carcinoma [Ackerman], Papillomatosis oral florid [Rock and Fisher], carcinomatoid [Gilbert] profuse conjuntival papillomatosis [Bazex], etc. These latter only refer to partial localizations or a special clinical form. That is why we believe the denonmination Papillomatosis Carcinoides, is preferable, which is its cutaneous, mucose or semimucose forms involves all of them. The treatments applied to the 18 cases presented have been very diverse: they vary from the elimination of the lesions by the application of topical podophylin to large surgical ablations. But most of them showed a regression or cure of their lesions by citostatics [methotrexate] not prevent the proliferative advance of the lessions. These therapeutic data can also contribute to its nosologic classification. In some cases they have an evolutive character with slow progression for years, still being curable with podophylin and in others that due to their chronic evolution with added supuration, and complications of the general health, make surgery necessary. In most cases, the antimetabolities are the therapy of choice the radiations seem inoperative. It may be noted that tumoral papillomatous lesions produced by virus, exist in veterinatian pathology (fibropapillomatosis in the bovine genitals, equine sarcoid, papilomatosis of goats, monkeys, etc.). Noteworthy are those of the oral mucosa of rabbits which are white greyish sesiles or pedunculated small nodules localized mostly on the inferior surface of tongue with a similar histology to the papilomatosis carcinoides. These observations would suggest a viral ethiology, even though all the efforts to isolate the virus of the lesions gave negative results. Our attention is drawn to case n. degrees 14. That began as a simple plantar wart. There have also been numerous cases in which from the beginning they were simple condylomas accuminatum, caused without any doubt by a virus. The carcinoid papillomatosis could be related to the spindle-cell carcinoma that developed in the areas of chronic infection with herpetic virus n. degrees 2, where the virus can be isolated from the lesions; the virus disappearing later with the development of the epithelial tumoral state [cases described previously by some authors as neophasias on vaccination scars and on recurrent genital herpes].
