Subcutaneous metastasis of prostate cancer.

OBJECTIVES: Prostate cancer tends to spread to regional lymph nodes and bone, and, to a lesser degree, to lung, liver, and brain. Metastases in other locations are exceptional. To review the frequency and clinical characteristics of metastasis to subcutaneous cellular tissue in adenocarcinoma of the prostate. METHODS: The case of a 71-year-old man diagnosed of adenocarcinoma of the prostate is reported. The patient underwent radical prostatectomy and artificial sphincter for stress urinary incontinence. RESULTS: During follow-up the patient showed biochemical progression, local recurrence, and bone metastasis. The disease metastasized in the subcutaneous tissue around the reservoir of the artificial sphincter. CONCLUSIONS: Prostate cancer is highly prevalent in our part of the world. The clinical finding of metastasis in organs other than bone or regional lymph nodes is accompanied by a short survival. Metastases in subcutaneous tissue may be underdiagnosed due to its indolent clinical course and possible absence of PSA elevation. In any case, subcutaneous metastases have an unfavorable prognosis.

[Adenomatoid tumor of the epididymis. Report of five cases]. / Tumor adenomatoide epididimario. Aportación de 5 casos.

OBJECTIVE: Adenomatoid tumor of the epididymis is unfrequent, benign, with no malignant outcomes described. METHODS: We report five cases, with patient's ages varying from 31 to 76 years, and tumor sizes from 6 to 30 mm. All patients underwent surgery with excision of the mass, some of them after several months of growing. In one of the cases the evolution reached six years. RESULTS: None of the cases presented recurrence or bad outcome after surgery. Pathology confirmed the benign adenomatoid character in all cases. CONCLUSIONS: Despite the clinical, ultrasound and physical examination findings suggest the localization in the epididymis and its benign character, surgical exploration is mandatory with surgical excision of the paratesticular mass.

[Sertoli cell malignant tumor]. / Tumor de células de Sertoli maligno.

OBJECTIVE: We report a new case of Sertoli cell testicular tumor with malignant characteristics. METHODS: 77 year-old male patient, suffering a general wasting syndrome presenting with a left solid testicular mass with the diagnosis of malignant Sertoli cell tumor after orchyectomy, without local, regional or distant dissemination, and a benign outcome after 18 months of follow-up. RESULTS: Sertoli cell tumor or androblastoma is classified as non-germ cell tumor derived from the stroma of the sexual cords. There are three types depending on its cellular composition: calcified big cell, sclerotic cell, and the most frequent of all, the classic type. CONCLUSIONS: Being the Sertoli cell testicular tumor rare, its malignant type is even rarer, accounting for not more than 10% of all. Despite the pathological characteristics related to malignancy, its posterior behaviour is unpredictable and not much known, the some than follow-up and treatment, because it is not sensible to cytostatic drugs. The existence of metastases continues to be the only valid parameter with prognostic value.

[Bladder metastasis of renal carcinoma]. / Metástasis vesical de carcinoma renal.

OBJECTIVES: We report the case of a patient who had underwent surgery for a clear cell renal carcinoma 2 years before presenting with metastasic extension to bladder on follow-up. METHODS: Radiological finding of a bladder mass during follow-up after nephrectomy. RESULTS: TURBT was carried out with the pathologic report of clear cell carcinoma, compatible with a primary renal origin. CONCLUSIONS: Bladder is a very rare place for metastasis from kidney tumors. Prognosis will depend on the time of appearance of such metastases.
