LOCAL RECURRENCE OF TUBULOCYSTIC CARCINOMA 4 YEARS AFTER RENAL RESECTION (A CLINICAL OBSERVATION)

The paper describes a clinical case of a local recurrence of tubulocystic carcinoma (TCC) in a 46-year-old man, a relatively good course (the relapse occurred after 4 years), who has been successfully operated on and is being followed up. This disease is a rare renal malignancy and, until recently, it has been referred to as collecting tubular carcinoma. However, this disease has come to be regarded as an independent nosological entity, by taking into account its certain morphological, immunohistohemical, and cytogenetic characteristics, as well as the nature of its course. About 80 TCC cases have been described to date. Further study of this disease and other rare renal malignancies will allow the more accurate elaboration of management tactics for such patients in terms of certain prognostic factors, which calls for a larger number of cases of this disease.
