Primary leiomyosarcomas arising in the penis are rare, with only 29 reported cases to date. We review the published records on this entity and describe an additional case of penile leiomyosarcoma occurring in a 53-year-old patient who underwent postectomy for a firm nodule in the prepuce. Four years later he experienced local recurrence which was successfully treated with partial penectomy.

Primary sarcomas of the kidney are rare, accounting for 1–3% of all renal malignancies. We describe an unusual case of renal leiomyosarcoma in a 41-year-old white woman who presented with a large smooth mass, which was mobile to the overlying structures and which occupied the right hypochondria and flank. Radical nephrectomy was carried out and the patient is well, without symptoms of relapse, 1 year after surgery. Leiomyosarcomas of the kidney have an aggressive and rapidly progressive natural history, with 5-year survival rates of 29–36%. Size <5 cm, low histological grade, absence of lymph node metastases and radical surgical treatment are all associated with a better prognosis. Irradiation and chemotherapy do not appear to alter the clinical course.

We describe a case of a monolateral duplex system and a ureterocele containing a gigantic stone in a 65-year-old woman who presented with pyelonephritis without any previous history of urinary tract infections or stone disease. Stone removal and double left ureteroneocystostomy with plastic widening of a narrowed obstructive side were performed. The ureteral stone measured 10.5 cm in greatest diameter, weighed 85 g and contained calcium oxalates and phosphates. Three months after surgery, radiology (intravenous urography and cystography) showed left unobstructed upper and lower urinary tracts and the absence of vesicoureteral reflux. Urine culture was negative 3, 6 and 9 months after surgery.

We report a case of non-functioning adrenal cortical carcinoma (ACC) presenting with metastatic disease to the tongue, which is an extremely uncommon onset for this neoplasm. Histologically, the lesion had the appearance of an anaplastic neoplasm, and a panel of immunohistochemical markers including vimentin, MART-1, S100 protein, HMB-45, smooth muscle actin, common muscle actin, desmin, CD31, CD34, CD68, EMA and cytokeratins, was helpful in excluding melanoma, as well as other mesenchymal and epithelial neoplasms.

The efficacy of weekly paclitaxel in androgen-independent prostate cancer and its addictive cytotoxicity with anthracycline derivatives led us to determine the safety and efficacy of a weekly schedule of paclitaxel and epirubicin. Between October 2000 and November 2002, 32 patients were enrolled in this study. Patients characteristics included a median age of 72 years (range 68-77), adequate hepatic, cardiac, renal and bone marrow functions, ECOG performance status of 1-2, and no prior chemotherapy. All patients had received hormonal manipulation and seven patients (22%) had received prior palliative radiation therapy. The regimen consisted of paclitaxel 70 mg/m2 i.v. infusion for 2 h and epirubicin 30 mg/m2 in bolus every week. Treatment was continued for 3 months or until disease progression or unacceptable toxicity were observed. During the study, prostate-specific antigen (PSA) was monitored and response was defined as a 50% reduction in PSA levels, to be confirmed 4 weeks later. Thirty-one patients were evaluable for toxicity and 21 for objective response. Seventeen patients (57%) had a decline above 50% in PSA level that lasted more than 4 weeks with a median time to PSA progression and a median duration of PSA response of approximately 5.5 months. Ten of the 21 patients with measurable disease (47%) had a confirmed objective response (one complete response and 20 partial responses). Thirteen of 25 symptomatic patients (56 %) had improvement in pain. The median time to disease progression was 7.6 months and the median survival was 12.9. The most prominent grade 3 toxicities were reversible myelosuppression and fatigue. Nausea, vomiting, diarrhea and peripheral edema were minimal. No evidence of cardiac toxicity was recorded. Alopecia was frequent, but reversible, in all patients. We conclude that despite the small sample size, this study demonstrates that the combination of weekly paclitaxel and epirubicin is a well-tolerated regimen for androgen-independent prostate cancer. The results imply that a combination of these agents in a weekly schedule may have clinical potential in prostate cancer treatment.
