[High grade transitional cell carcinoma with signet ring cell pattern. Case report].

OBJECTIVE: The presence of signet ring cells within a transitional cell carcinoma is a factor of poor prognosis. METHODS: We report the case of a 69-year-old male patient with the diagnosis of high grade transitional cell carcinoma with signet ring cell pattern, the presence of which could have been foreseen in serial cytological tests performed after the clinical debut. RESULTS: To achieve such a diagnosis, it is necessary to rule out the possibility of metastasis or infiltration of a neoplasia from other organ. CONCLUSION: Both the presence of an in situ neoplasia or the coexistence of infiltrative transitional cell tumor can help to determine primary origin of these neoplasias.

[Study of urethritis in males using Papanicolaou smear].

Sexual pathogens, cell types and morphologic alterations of urethral epithelial cells were investigated by means of the Papanicolaou smear in 110 heterosexual men. Seventy-five patients with urethritis were included: 17 (22.6%) with gonococcal urethritis (GU) and 58 (77.3%) with non-gonococcal urethritis (NGU). Thirty-five males without symptoms or signs of urethritis comprised the control group. An increase in epithelial cell dissociation was observed in patients with urethritis. Non-specific inflammatory changes were statistically more common in patients with urethritis than in controls, and more severe in GU (65%) than in NGU (15.5%). Nuclear atypia was a common finding (43.5%) in infections due to C. trachomatis. Mucus was associated with the presence of urethritis although no differences regarding etiology were found. No polimorphonuclear neutrophils were observed in the exudate of three patients (5%) with NGU. There was a statistically significant presence of lymphocytes in patients with urethritis, particularly in GU (45%), more frequent than in NGU (15.5%). Erythrocytes were also significantly more frequent in urethritis, with a greater proportion in GU (94%) than in NGU (64%). Plasma cells, eosinophils, and histiocytes were only observed in a few patients with urethritis. The Papanicolaou smear had a sensitivity of 47% and a specificity of 90% in Chlamydia trachomatis infections.
