Cutaneous metastasis from renal cell carcinoma is believed to be rare. We present our experience with 10 (3.3%) cases seen in the last 12 years among 306 cases of renal adenocarcinoma treated at our center. There were 9 males and 1 female. Age ranged from 30 to 65 years (average 45 years). 5 patients had skin metastases at the time of presentation (stage IV). In one of them the skin nodule, rather than urologic symptoms, was the presenting complaint. 5 patients presented with skin metastasis during follow-up after nephrectomy. The average time to skin metastasis was 51 months for patients in stage I and 13 months in stage IIIb. The scalp was the most common site of metastasis followed by chest and abdomen. 90% of patients had secondaries in at least one other site, most commonly in lungs (4 cases) and bones (5 cases). 4 patients were treated with interferon-α 6 MIU, subcutaneously, three times a week for varying periods from 3 to 4 months but there was no response. In conclusion, cutaneous secondaries from RCC, though uncommon, are not very rare. A few patients may present with a skin mass before detection of the renal tumor. Patients with low-stage disease at presentation may also develop cutaneous secondaries, therefore a prolonged follow-up is required. The commonest site for cutaneous metastasis from RCC is the scalp and face. Most patients had at least one other site of systemic metastasis, hence they were not candidates for curative therapy. Interferon therapy was not helpful. Mean survival after detection of cutaneous metastasis was 7 months.

Determination of the apparent diffusion coefficient (ADC) of the prostate in men (n = 60) with raised prostate-specific antigen (PSA) or an abnormal digital rectal examination (DRE) prior to transrectal ultrasound (TRUS) guided biopsy using endorectal DWI is reported. Patients were categorized into different groups based on their PSA levels. The mean ADC was calculated from a number of regions of interest (ROIs) for the whole of the peripheral zone (PZ) and the central gland (CG). A total of 1108 ROIs were analyzed from 60 patients. The mean ADC value of the PZ was higher than that of the CG in controls. A total of 23 out of 60 patients were positive for malignancy on biopsy, and the mean ADC of the PZ was lower in these patients compared with those who were negative. Moreover, the mean ADC obtained for the whole of the PZ of the prostate in different groups of patients and controls showed a decreasing trend. A plot between PSA and mean ADC for the PZ showed non-linear association with logarithmic decrease in ADC. The mean ADC of the CG was not significantly different in patients who were positive or negative for malignancy in biopsy. In addition, a cut-off value of 1.17 x 10(-3) mm2/s (sensitivity = 73% and specificity = 74%, area under the curve = 0.83) for the mean ADC for the whole of the PZ of patients was determined by using the receiver operating characteristic curve (ROC) to predict malignancy of the PZ.

Two cases of vesicouterine fistula, caused by lower-segment cesarean section, are presented. Both cases had classical symptoms of Youssef’s syndrome, i.e. cyclic hematuria, absence of vaginal bleeding and complete urinary continence. These patients were treated by the continuous administration of an estrogen-progestogen combination for 6 months. However, it failed in 1 case requiring transabdominal transperitoneal closure of the fistula with an interposition of omentum. We feel that hormonal treatment may be tried as first modality in the treatment of Youssef’s syndrome, before resorting to surgery.

Urinary leakage following obstetric or gynecologic surgery is a dreaded complication, most often caused by a urogenital fistula. Of these, uretero-uterine fistulae are relatively rare and pose a diagnostic and therapeutic dilemma. A 29-year-old woman presented with paradoxical incontinence of urine for 3 months. She had developed vaginal leakage of urine 2 weeks following an uneventful cesarean section. Conservative measures in the form of catheterization and bed rest did not relieve her symptoms. Subsequent examination and investigations revealed that she had a ureterouterine fistula. The case is discussed as well as the diagnostic modalities and treatment options.
