Ovotesticular disorder of sex development with a prostatic gland and review of literature.

Ovotesticular disorder of sex development (OTDSD) is a rare condition and defined as the presence of ovarian and testicular tissue in the same individual. Most of patients with OTDSD have female internal genital organs. In this report, we present a case in which, we demonstrated prostate tissue using endoscopic and radiologic methods in a 46-XX, sex determining region of the Y chromosome negative male phenotypic patient, with no female internal genitalia. Existence of prostate in an XX male without SRY is rarely seen and reveals a complete male phenotype. This finding is critical to figure out what happens in embryonal period.

Antioxidant system activation in prostate cancer.

The activities of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) and the levels of copper, zinc, and malondialdehyde were determined in 21 age-, sex-, and body-mass-index-matched prostate cancer patients; 50 patients diagnosed with benign prostatic obstruction (BPO) were compared to 50 healthy male subjects acting as controls. The patients were divided into two groups depending on the stage of the disease (group 1 [organ-confined] and group II [advanced disease]) and into three subgroups according to differentiation criteria: subgroup A (n = 5, Gleason sum 2-4, well differentiated); subgroup B (n = 9, Gleason sum 5-7, moderately differentiated), and subgroup C (n = 7, Gleason sum 8-10, poorly differentiated). The MDA levels were higher and the antioxidant activity and Zn levels lower in the prostate cancer groups than in the healthy control and BPO groups. These results confirm the value of therapies aimed at increasing the antioxidant capacity and encourage the use of plasma and erythrocyte Zn levels in the differential diagnosis of BPO and prostate cancer. The MDA levels can be used in the diagnosis and follow-up of prostate cancer.
