Authors present a case of giant adrenal myelolipoma, where the tumor was hormonally inactive but caused abdominal and flank pain. The huge tumor, a 20x18x10 cm mass, was surgically removed. The ipsilateral kidney was preserved.
Two cases of spontaneous pelvic rupture are presented. In Case 1 (female, 49 years) and Case 2 (male, 63 years) the rupture was due to obstruction and tumorous compression of the ureter, respectively. Authors deal with the diagnostic difficulties and the possibility of a cure without open surgery. Conservative therapy (double-J ureteral catheter and pigtail catheter) was successful in both cases. The pertinent literature is briefly reviewed.
This is a case of a 56-year-old male patient suffering from a combination of prostate carcinoma and malacoplakia. A 56-year-old male patient was admitted in our Department because ischuria due to the enlargement of the prostate. Perineal needle biopsy was done resulting carcinoma of prostate. Radical prostatectomy was performed. Histology proved carcinoma and a great part of the enlarged prostate consisted of malacoplakia. Questions related to the morphology, tissue structure as well as diagnosis are briefly surveyed. This is the first report on the rarely occurring combination of prostate carcinoma and malacoplakia treated by radical retropubic prostatectomy.
21 human renal cell carcinomas (RCC) were xenotransplanted into artificially immunosuppressed mice. 4 tumors grew successfully retaining some characteristics of the primary tumors (according to morphology and karyotype analysis), but losing metastatic capacity. One of the serially transplantable tumors (HT 40) with hyperdiploid cellular DNA content and estrogen receptor positivity failed to respond to the single maximally tolerated dose of several cytotoxic agents.
Authors review the case history and follow-up of a rare malignant fibrous histiocytoma patient, based on the relevant literary data. The tumour filled the retroperitoneum on the right side, in front of the right kidney. Intravenous urography and computer tomography revealed a 10 x 15 cm sized mass, suspect of being a kidney tumour. Upon surgery, the tumour was found to be a retroperitoneal malignant fibrous histiocytoma. In connection with the case, a brief review is given of the storiform type of malignant fibrous histiocytoma, regarding its aetiological, clinical and pathological aspects, the difficulties in diagnosis, as well as the therapeutic possibilities. Authors regard their case worthy of publication because of the retroperitoneal location and significant size of the tumour, and because of the unproven diagnosis prior to surgery. Even after 4 years the patient is symptom- and complaint-free, and CT has revealed no metastases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
