Objective: To assess the choroidal structural characteristics in the first and third trimesters in pregnant women using enhanced depth imaging optical coherence tomography and binarization method.

Design: Prospective study.

Participants: Twenty-five eyes of 25 pregnant women in the first trimester (group 1) and 25 eyes of 25 pregnant women in the third trimester (group 2) were examined. Healthy age-matched 25 participants were enrolled as a control group (group 3).

Methods: The choroidal thickness (CT) was measured at 3 points; subfoveal, 1500 μm nasal to the fovea, and 1500 μm temporal to the fovea. Total choroidal area, luminal area, stromal area, stroma/lumen ratio, and choroidal vascularity index (CVI) were measured by Image-J software.

Results: The mean subfoveal and nasal CT were statistically significantly increased in group 1 compared with controls (p = 0.005 and p = 0.004, respectively). The mean temporal CT was statistically significantly increased in group 1 compared with groups 2 and 3 (group 1 vs group 2, p = 0.043; group 1 vs group 3, p = 0.011). The mean total choroidal area, stromal area, and luminal area were significantly increased in groups 1 and 2 compared with control group (p < 0.001, p < 0.001, p < 0.001, and p < 0.001, p = 0.002, p = 0.002, respectively). There were no statistically significant differences among groups in terms of mean stroma/lumen ratio and CVI (p = 0.148 and p = 0.312, respectively).

Conclusions: There was a significant increase in subfoveal, temporal, and nasal CT in the first trimester. Total choroidal, stromal, and luminal areas were significantly increased in the first and third trimesters.

Primary Benign Phyllodes Tumor of The Vulva: Case Report and Review of Literature.

Eur J Breast Health 2019 Jul 1;15(3):196-199. Epub 2019 Jul 1.

Department of Gynecology and Obstetrics, Ahi Evran University Training and Research Hospital, Kırşehir, Turkey.

Phyllodes tumor (PT) of the vulva is very rarely seen and has been reported in only 17 cases in English literature. It is still uncertain that proliferative mammary gland lesions including PT in the anogenital region originate from ectopic breast tissue or from local adnexal structures. We report a case of primary benign PT of the vulva in a 41-year-old female patient. Microscopic examination revealed biphasic tumoral formation with typically extensive leaf-like papillary structures growing toward slit-like spaces under the skin. In immunohistochemical examination, more than 50% of epithelial cells showed a positive reaction with ER, PR, and panCK and a focal positive reaction with GCDFP-15. Myoepithelial cells showed a positive reaction with SMA, CD10, and WT-1. In this report, we underline the clinicopathologic features of PT localized to an unusual site, and also discuss its etiology, differential diagnosis in the light of the current literature.
