Klinefelter's syndrome is characterized by hypergonadotropic hypogonadism, 47,XXY karyotype, gynecomastia, azoospermia and testicular atrophy with hyalinization of seminiferous tubules and hyperplasia of Leydig cells. Some cases of Klinefelter's syndrome with unexplainably low levels of gonadotropins have been reported in the literature. Two additional cases of Klinefelter's syndrome with hypogonadotropic hypogonadism and absence of Leydig cells are described.
OBJECTIVES: The present study discusses both primary and secondary malignant lymphoreticular proliferative tumors of the urinary tract. METHODS: Two patients with urinary tract involvement are described: one female and one male with bladder and prostate involvement, respectively. RESULTS: Both cases presented clinical features that were not distinct from those of other tumors of the urinary tract. CONCLUSIONS: The anatomopathological study is essential to the differential diagnosis of urinary tract involvement from non-Hodgkin lymphoma and discards other extralymphatic conditions.
