Colloid Carcinoma of the Uterine Cervix and Its Immunohistochemical Analysis: A Case Report
Nermin Koc,Sevcan Arzu Arinkan,Nurver Ozel Ozbay,Selcuk Selcuk 대한병리학회 2018 Journal of Pathology and Translational Medicine Vol.52 No.1
Colloid carcinoma, which is a very rare tumor of the uterine cervix, is composed of an excessive amount of mucus and a relative paucity of tumoral glandular cells within them. Herein, we report a rare case of colloid carcinoma of the cervix with adenocarcinoma in situ (AIS), intestinal and usual types, and endocervical adenocarcinoma (usual type) components. We also discuss the morphological and immunohistochemical characteristics of this tumor. A 51-year-old woman was referred to our outpatient clinic with the symptom of genital bleeding lasting for 5 months. She had a cervix surrounded by an irregular tumor with a diameter of 5 cm. The colloid carcinoma cells were positive for MUC2, MUC5AC, and cytokeratin (CK) 7, focal positive for CDX2, and negative for MUC6 and CK20. Also, the intestinal type AIS showed a similar staining pattern. Colloid carcinoma cells producing mucin showed an intestinal phenotype and AIS. The intestinal type can be considered as a precursor lesion of colloid carcinoma.

Background: The objective of this study was to compare the classical method and Sectioning and Extensively Examining the Fimbriated End Protocol (SEE-FIM) in detecting microscopic lesions in fallopian tubes with gynecological lesions. Methods: From a total of 1,118 cases, 582 with various parts of both fallopian tubes sampled in three-ring-shape sections and 536 sampled with the SEE-FIM protocol were included in this study. Pathological findings of cases with endometrial carcinoma, non-uterine pelvic malignant tumor, ovarian borderline tumors, premalignancy, and benign lesions were compared. Results: We detected two tubal infiltrative carcinomas among 40 uterine endometrioid adenocarcinomas, 15 serous tubal intraepithelial carcinomas in 39 non-uterine pelvic serous high-grade carcinoma cases, seven papillary tubal hyperplasias in 13 serous borderline tumor cases, and 11 endometriotic foci and four adenomatoid tumors among all cases sampled with the SEE-FIM protocol. Using the classical method, we detected only one serous tubal intraepithelial carcinoma in 113 non-uterine pelvic serous high-grade carcinoma cases and two papillary tubal hyperplasia cases in 31 serous borderline tumors. We did not identify additional findings in 185 uterine endometrioid carcinoma cases, and neither endometriotic focus nor adenomatoid tumor was shown in other lesions by the classical method. Conclusions: Benign, premalignant, and malignant lesions can possibly be missed using the classical method. The SEE-FIM protocol should be considered especially in cases of endometrial carcinoma, nonuterine pelvic serous cancers, or serous borderline ovarian tumors. For other lesions, at least a detailed examination of the fimbrial end should be undertaken.

Body composition: A predictive factor of cycle fecundity

Objective: To study the effect of body composition on reproduction in women with unexplained infertility treated with a controlled ovarian hyperstimulation and intrauterine insemination programme. Methods: This prospective observational study was conducted on 308 unexplained infertile women who were scheduled for a controlled ovarian hyperstimulation and intrauterine insemination programme and were grouped as pregnant and non-pregnant. Anthropometric measurements were performed using TANITA-420MA before the treatment cycle. Body composition was determined using a bioelectrical impedance analysis system. Results: Body fat mass was significantly lower in pregnant women than in non-pregnant women ($15.61{\pm}3.65$ vs. $18.78{\pm}5.97$, respectively) (p=0.01). In a multiple regression analysis, body fat mass proved to have a stronger association with fecundity than the percentage of body fat, body mass index, or the waist/hip ratio (standardized regression coefficient${\geq}0.277$, t-value ${\geq}2.537$; p<0.05). The cut-off value of fat mass, which was evaluated using the receiver operating characteristics curve, was 16.65 with a sensitivity of 61.8% and a specificity of 70.2%. Below this cut-off value, the odds of the pregnancy occurrence was found to be 2.5 times more likely. Conclusion: Body fat mass can be predictive for pregnancy in patients with unexplained infertility scheduled for a controlled ovarian hyperstimulation and intrauterine insemination programme.
