[Penile metastasis of renal cell carcinoma]. / Metástasis peneana de un carcinoma de células renales.

The tumour dissemination to penis from renal cell carcinoma is a rare occurrence; generally, it is seen in advanced stages of the disease, such that occurred in our patient that indicated a poor prognosis. A lesion node, high, painless, the size middle, located in the side right to penis, at long term free of symptoms associated was found. The histological examination of the specimen after cold biopsy demonstrated a metastasis from renal carcinoma.

Metástasis peneana de un carcinoma de células renales / Penile metastasis from renal cell carcinoma

La diseminación tumoral a pene por una neoplasia renal es un hecho poco habitual, ocurriendo generalmente en estadios muy avanzados, tal como sucedió en el enfermo comunicado, y lleva asociado un mal pronóstico. Se trata de una lesión nodular, elevada, indolora, de moderado tamaño, localizada en hemipene derecho, de larga evolución en ausencia de síntomas acompañantes; el estudio histológico después de biopsia fría demostró una metástasis por carcinoma renal.

[Squamous cell carcinoma of the prostate: a further case]. / Carcinoma de próstata de células escamosas. Un nuevo caso.

We report one rare case of squamous cells prostate tumor. This histological pattern accounts for the 0.5-1% of all prostatic malignancies with certain clinical and evolutive aspects that are from those of prostate adenocarcinoma. Review of the literature seems to have a very poor prognosis such that occurred in our patient who died after 2 month of diagnosis with a poor response to the habitual treatment, perhaps due to this different cell of origin.

[Oat cell carcinoma of the bladder]. / Carcinoma de células pequeñas oat cell de vejiga.

Small cell carcinoma (CCP) of the urinary bladder is an uncommon tumor, having usually an aggressive behavior. We report a new case of CCP seen at our centre and we communicate the applied therapeutic method. Although total cystectomy followed by chemo and radiotherapy seems to be the most effective treatment, we have carried out radical RTU of the bladder accompanied by chemo and radiotherapy as conservative therapy obtaining complete remission after 2 year of diagnosis, without local and distant evidence of the disease.

[Leydig cell tumor. Two new cases]. / Tumor de células de Leydig. Dos nuevos casos.

The Leydig's cell tumours are the most common of all non germ cell tumour of the testis, that clinical findings is different by age of presented. We report two new cases of Leydig cell tumour diagnosed in our centre having different presentation form, in old adults with feminizing features and occult tumour, and as a testicular nodule pain, respectively. The analytical, clinical, diagnostic aspects and therapeutic of the uncommon disease are discussed.

Carcinoma de próstata de células escamosas. Un nuevo caso / Squamous cell carcinoma of the prostate a new case

Se comunica un raro caso de carcinoma prostático de células escamosas. Esta variedad histológica supone el 0,5-1 per cent del total de cánceres malignos de la próstata, con ciertos rasgos sintomáticos y evolutivos que le difieren del adenocarcinoma de la glándula prostática. Revisada la literatura, parecen tener un peor pronóstico, tal como ocurrió en nuestro paciente quien falleció a los 2 meses del diagnóstico con una mala respuesta a los tratamientos habituales, quizás debido a su diferente origen celular (AU)

Carcinoma de células pequeñas oat cell de vejiga / Oat cell carcinoma of the bladder

El carcinoma de células pequeñas (CCP) de localización vesical es un tumor poco frecuente, teniendo por lo general una evolución agresiva. Presentamos un nuevo caso de CCP aparecido en nuestro servicio y comunicamos la actitud terapéutica aplicada. Si bien la exéresis total de vejiga seguida de quimio y radioterapia parece ser el tratamiento más efectivo, hemos realizado RTU radical de vejiga asociada a quimio y radioterapia como finalidad conservadora, consiguiendo remisión completa después de 2 años del diagnóstico, sin evidencia local y a distancia de la enfermedad (AU)

Tumor de células de Leydig. Dos nuevos casos / Leydig's cell of tumor. Two new cases

Los tumores de células de Leydig son las neoplasias más habituales de todos los cánceres de testículo no germinales, cuya clínica difiere según la edad de aparición. Comunicamos dos nuevos casos de tumores de células de Leydig observados en nuestro servicio teniendo distinta forma de presentación, en varones adultos con signos de feminización y tumor oculto, y como nódulo doloroso testicular, respectivamente. Se destacan los aspectos analíticos, clínico-diagnósticos y terapéuticos de esta infrecuente patología tumoral (AU)

[Syphilitic penile pseudotumor. Report of a case]. / Pseudotumor peneano luético. Presentación de un caso.

The syphilis is a venereal disease of sexual transmission that incidence is increasing in several groups populations. We report a case of a patient with secondary syphilis who consulted for an atypical solid mass to penile. The clinical evolution, histological examination and analytical tests confirmed the diagnosis of genital syphilis having a satisfactory response to specific antibiotic treatment. The epidemiological, clinical, diagnostic aspects and therapeutic of the genital ulcer disease are discussed.

[Subcutaneous supramammary metastasis of prostatic carcinoma]. / Metástasis subcutánea supramamaria de un carcinoma de próstata.

The subcutaneous dissemination at the prostate carcinoma is rare. Generally, but not frequently, it is seen in patients in advanced stages of the disease and in the terminal phase. We wish to communicate the case of a subcutaneous metastasis as the primary appearance of this neoplasm, whose existence was confirmed by immunohistological examination by means of PAAF, and with satisfactory response to testosterone deprivation.
