Clinicopathologic and immunohistochemical profile of ovarian metastases from colorectal carcinoma
Metastasis of colorectal adenocarcinoma of the ovary is not an uncommon occurrence and ovarian metastases from colorectal carcinoma frequently mimic endometrioid and mucinous primary ovarian carcinoma. The clinical and pathologic features of metastatic colorectal adenocarcinoma involving the ovary is reviewed with particular focus on the diagnostic challenge of distinguishing these secondary ovarian tumors from primary ovarian neoplasm. Immunohistochemical stains that may be useful in the differential diagnosis of metastatic colorectal tumors to the ovary and primary ovarian tumors are detailed
Cytodiagnosis of primary thyroid lymphoma coincident with unnoticed papillary thyroid carcinoma: A case report and review of the literature
Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, whereas primary thyroid lymphoma is very rare. Here, we report a case in which a right-sided nodule measuring 4.3 × 2.2 cm was examined using fine-needle aspiration biopsy. This revealed abundant monomorphic non-cohesive large lymphoid cells without thyroid follicular cells, on which basis acytodiagnosis of lymphoma coincident with lymphocytic thyroiditis was made. Subsequent histologic examination revealed CD45−, CD20+, and Bcl-6 + and cytokeratin-, CD3-, CD5-, and CD30-negative tumor cells arranged diffusely in the whole thyroid coexisting with a separate PTC nodule sized 1.3 × 1.0 cm in the right lobe. The key point exemplified by this case is that a cytodiagnosis of this extremely rare coexistence of PTC and lymphoma can be made by adequate sampling of both nodules preoperatively. In our case, only one nodule formation was sampled, and therefore the coexisting PTC was not detected with cytology preoperatively
A rare case of ovarian yolk sac tumour arising from mucinous adenocarcinoma in a 67-year-old woman
Expression of androgen, estrogen, and progesterone hormone receptors in the penile tissues of children with different types of hypospadias
OBJECTIVE: Androgen (AR), Estrogen (ER) and Progesterone (PR) hormones play an important role in the prenatal and postnatal development of urogenital tract and especially the penis. The expressions of AR, ER and PR receptors in penile tissues in children with hypospadiases had also been shown previously. In this leading study, to demonstrate of the sex hormone receptor expression in cases with different types of hypospadias were aimed

The cribriform morphology impairs Gleason 7 prostate cancer lesion detection on multiparametric magnetic resonance imaging
© 2022 Wiley Periodicals LLC.Background: Prostate multiparametric magnetic resonance imaging (mpMRI) is a useful tool for the detection of tumor lesions however, some clinically significant lesions are still missed. We determined whether the cribriform pattern has an effect on lesion detection in mpMRI. Methods: We reviewed the single-institution database of the patients who underwent mpMRI before radical prostatectomy. We included the patients only with the Gleason 7 final pathology of open radical prostatectomy with curative intent between 2016 and 2021. Prostatectomy mappings according to the 16-sector map and cribriform patterns were re-evaluated by two genitourinary pathologists. Prostate mpMRIs were read by two genitourinary radiologists. If the index and nonindex lesions in pathology mapping were matched with mpMRI as Prostate Imaging Reporting and Data System-3 or higher, it was defined as detectable. We compared the detection rates of lesions with and without cribriform morphology. In regression analysis, we also assessed the factors affecting the detectability of prostate cancer lesions. Results: A total of 120 patients and 157 lesions were included in our study. While 52 of 83 cribriform pattern positive lesions could be detected in mpMRI, 59 of 74 cribriform pattern negative lesions could be detected (62.7% vs. 79.7%, respectively, p = 0.019). The lesions were also distributed homogeneously according to diameters and analyzed separately. All lesions between 21 and 30 mm with the negative cribriform pattern were detected on mpMRI. However, only 77.8% of cribriform pattern positive lesions between 21 and 30 mm could be detected (p = 0.034). The Higher D'Amico risk group and the absence of cribriform morphology were independent predictors for the lesion detection on mpMRI. Conclusion: The presence of cribriform pattern in Gleason 7 prostate cancer lesions decreases the lesion detection rate of mpMRI
Clinical significance of benign endometrial cells found in papanicolaou tests of Turkish women aged 40 years and older
Background: Spontaneously exfoliated benign-appearing endometrial cells (BEC) on a Papanicolaou smear might indicate endometrial pathology in postmenopausal women, necessitating further investigation. A cut-off age of 40 years was included in the Bethesda System 2001 based on studies of clinical significance of endometrial cells in Pap smears in Western countries.
Aims: The purpose of this study was to determine the significance of age subgroup for women with a cytological diagnosis of BEC, regardless of menopausal status, in a retrospective cohort of Turkish women.
Materials and Methods: Between October 2006 and November 2011, 41 patients with a BEC diagnosis and 64 patients with a cytological diagnosis of normal smear (NS) were enrolled; regardless of menopausal status, these women were
40 years and older and for whom follow-up endometrial biopsies had been performed.
Results: On subsequent histopathologic evaluation, no malignant lesion was detected in women aged 40-50 years compared to three endometrioid-type adenocarcinomas in women older than 50 years with cytological diagnosis of BEC. There was a significant difference between women older than 50 years with cytologic diagnosis of BEC and NS in relation to premalignant lesions on histopathologic evaluation; however, this was not the case for women aged 40-50 years.
Conclusions: According to our study, reporting BEC for women aged between 40 and 50 years has minor clinical significance but is significant for women older than 50 years, regardless of menopausal status. Larger sample size would be appropriate to confirm the results of the current study
Determining the cut-off values of tumor diameter, degree of extraprostatic extension, and extent of surgical margin positivity with regard to biochemical recurrence of prostate cancer after radical prostatectomy
Background: The pre-biopsy (bx) prostate-specific antigen (PSA) level, tumor volume/diameter, degree of extraprostatic extension (EPE), and extent of surgical margin positivity have been shown to be significant prognostic parameters of biochemical recurrence (BCR) after radical prostatectomy. The present study assessed the cut-off values of the pre-bx PSA level, maximum tumor diameter, radial and circumferential distances of EPE, and circumferential length of surgical margin (SM) positivity with regard to BCR
