Neuroendocrine tumors of the urinary bladder - Report of two cases

Primary paraganglioma and small cell neuroendocrine carcinoma of the urinary bladder are rare tumors, comprising 0.05% of all bladder tumors and <1% of all malignant bladder tumors, respectively. These tumors can be the cause of a diagnostic dilemma or misdiagnosis on morphology. Paraganglioma is often mistaken for urothelial carcinoma and small cell carcinoma for poorly differentiated carcinoma or lymphoma. Herein, we report a case of primary paraganglioma and another of a small cell carcinoma of the urinary bladder and discuss their closest differential diagnoses. The diagnostic pitfalls should be kept in mind so that correct, timely diagnosis of these entities can be made due to implications in the management and prognosis.

46XX pure gonadal dysgenesis with dysgerminoma along with leydig cells: a unique presentation

Authors report a unique case of 46XX gonadal dysgenesis, with dysgerminoma in one ovary and other streak ovary with hilar nests of leydig cells. It is exceptionally rare to find dysgerminoma in a dysgenetic gonad with no Y chromosome and so is the presence of leydig cells in the contralateral streak ovary in a patient with 46XX pure gonadal dysgenesis.

A prospective study of cervical lesions diagnosed by liquid based cytology in Western Rajasthan, India population

Background: Carcinoma cervix is the second most common malignancy of women in India after breast cancer. The present study was conducted to determine the spectrum of cervical lesions by liquid-based cytology in Western Rajasthan population.Methods: It is a Prospective study on 1087 cervical samples carried over a period of 1 year. Cervical samples were taken and processed by SurePath™ LBC.Results: Of total 1087 cases 959 were negative for intraepithelial lesion or malignancy (88.22%). 88 cases (8.09%) were reported as unsatisfactory. Among the non- neoplastic cases- bacterial vaginosis was reported in 209 cases (21.8%), Candida in 77 cases (8.02%), both Candida and bacterial vaginosis in 12 cases (1.25%), reactive cellular changes in 193 cases (20.12%), and Trichomonas vaginalis in 01 case. Among pre-malignant and malignant lesions, 40 cases (4.17%) the distribution was as follows-atypical squamous cells of undetermined significance 16(1.67%), atypical squamous cell-cannot rule out high grade 08 cases (0.83%), Low grade squamous intraepithelial lesion 04 cases (0.42%), high grade squamous intraepithelial lesion 07 cases (0.73%), Atypical glandular cell favoring neoplastic 01 case (0.15%), and squamous cell carcinoma 04 cases (0.42%). Histopathological co-relation of premalignant and malignant lesions was further studied.Conclusions: Liquid based cytology is an effective screening and diagnostic procedure for cervical abnormalities. Among pre-malignant and malignant lesions, histo-pathological correlation increased with increased grade of severity of lesions. To the best of knowledge, this is the largest study of liquid based cytology in the Western Rajasthan.
