We examined the current status of human T-cell leukemia virus type 1 (HTLV-1) carrier in Japanese pregnant women, according to the results of HTLV-1 screening and confirmation tests of women who gave birth in Japan in 2011. We requested 2642 obstetrical facilities to provide information of HTLV-1 tests and 71.3% of them responded. Considering the response rate and the rate of implementation of confirmation tests, the number of HTLV-1 carrier in Japanese pregnant women was estimated to be 1620 (0.16%) per year.

We report a woman with ascites, hydrothorax, pancreatic tumor, left cystic ovarian tumor, and an elevated serum cancer antigen 125 level.

Flow cytometry was used in the scoring of acrosome-reacted human sperm. Propidium iodide was used for detection of the nonviability of the sperm. Fluoresceinated pea lectin was used to detect acrosome-reacted sperm. The results obtained by flow cytometry and those obtained by fluorescence microscopy were compared to determine if flow cytometry can serve as a more accurate, faster, and simpler method. It was possible to detect human sperm by flow cytometry. The percentage of propidium iodide labeled sperm determined by flow cytometry was close to that obtained by fluorescence microscopy. Comparison of the percentage of acrosome-reacted sperm determined by flow cytometry and fluorescence microscopy showed that these methods gave very similar results (r = 0.98, p less than 0.001). Objective scoring of more sperm was possible by flow cytometry than by fluorescence microscopy, and flow cytometry was useful as a simple method for evaluation of acrosome-reacted human sperm.

There is a lack of evidence for a significant correlation between recently increasing CD rates and decreasing PM rates in Japan.

Peritoneal endometriosis presenting as a tumor is very rare. A case of peritoneal endometriosis in the broad ligament presenting as a large tumor is reported. A 39-year-old woman had a solid and cystic tumor with many microcysts, measuring 17 x 13 x 3.5 cm, mainly located in the right posterior broad ligament. Histologically, the tumor consisted of many endometrial glands associated with various amounts of endometrial stroma. Neither the glands nor the stromal cells had cellular atypia. We diagnosed peritoneal endometriosis presenting as a tumor. Among the six cases (five previously reported cases and our case) of tumor-like endometriosis in the peritoneum, two cases (33%) had received tamoxifen therapy and four cases (67%) had cystic or solid and cystic tumor. Among them, the tumor size ranged from 3 to 17 cm in diameter, and our case was the largest. In conclusion, this case is rare, but it is important for pathologists to be aware of the phenomenon (that extensive peritoneal endometriosis produces a large tumor) in the histological diagnosis of a tumor in the peritoneum.
