RESUMEN
We report a case of scrotal squamous cell carcinoma in a 67-year-old man that presented as a recurrent nonhealing scrotal abscess. Radical scrotectomy and bilateral simple orchiectomy were performed. A pudendal thigh flap was used for wound closure. To our knowledge, this is the first report of its use after radical surgery for scrotal cancer. The clinical features, staging, and treatment of scrotal squamous cell carcinoma are reviewed. In this report, we highlight the importance of including scrotal cancer in the differential diagnosis when evaluating a scrotal abscess.
RESUMEN
BACKGROUND: The endoscopic injection of dextranomer-hyaluronic acid has become a popular treatment for childhood vesicoureteral reflux. Treated children are predominantly girls, and many are now entering adulthood. It has been reported in children that the radiographic appearance of implants may lead to misdiagnoses and unnecessary, invasive diagnostic procedures. CASE: We report the case of a woman treated with dextranomer-hyaluronic acid for childhood vesicoureteral reflux misdiagnosed with a bladder tumor on transvaginal ultrasonography. Renal ultrasound examination and urinalysis results were normal. Invasive testing was avoided given the history and characteristic ultrasonographic appearance of retained implants. CONCLUSION: It is important for health care providers to be aware of the radiographic appearance of dextranomer-hyaluronic acid implants in adults and to elicit an appropriate past medical history to avoid misdiagnosis and invasive diagnostic procedures.

Tubulocystic carcinoma (TC) is a rare primary renal tumor that has been recently described in the pathology literature. Formerly termed low-grade collecting duct carcinoma, further molecular analysis has shown TC to be a distinct entity that is separate from the more aggressive collecting duct carcinoma. Previous series have described the microscopic and immunohistochemical features of this tumor. We describe the natural history of this tumor in a patient who was followed with active surveillance for several years and then underwent partial nephrectomy. Long-term follow-up has shown no evidence of disease. A review of the pertinent literature is performed.

BACKGROUND: The upward trend in industrial nations in the incidence of male genitourinary (GU) conditions may be attributed to increased exposure to endocrine disruptors. Polybrominated biphenyl (PBB), a brominated flame retardant, is one such suspected endocrine disruptor. OBJECTIVE: We investigated the relationship between maternal serum levels of PBBs and GU conditions among male offspring exposed in utero. METHODS: In this cohort study of sons born to women accidentally exposed to PBBs during 1973-1974, we examined self-reported data on GU conditions among male offspring in relation to maternal serum PBB levels. We used generalized estimating equations to calculate odds ratios (ORs), controlling for gestational age at birth. RESULTS: Of 464 sons, 33 reported any GU condition (13 hernias, 10 hydroceles, 9 cryptorchidism, 5 hypospadias, and 1 varicocele). Four reported both hernia and hydrocele, and one both hernia and cryptorchidism. After adjustment for gestational age at birth, sons of highly exposed women (> 5 ppb) were twice as likely to report any GU condition compared with sons of the least exposed women [< or =1 ppb; OR = 2.0; 95% confidence interval (CI), 0.8-5.1]. This risk was increased when we excluded sons born after the exposure but before the mother's serum PBB measurement (OR = 3.1; 95% CI, 1.0-9.1). We found evidence of a 3-fold increase in reported hernia or hydrocele among sons with higher PBB exposure (test of trend p-value = 0.04). Neither hypospadias nor cryptorchidism was individually associated with PBB exposure. CONCLUSIONS: Although cryptorchidism and hypospadias were not associated with in utero PBB exposure, this study suggests that other GU conditions may be associated with exposure to endocrine-disrupting chemicals during development.
