The Spectrum of Central Nervous System Tumors at a Tertiary Care Center Primarily Serving a Rural Population.

Background Central nervous system (CNS) tumors cause significant mortality and morbidity in all age groups. There was no data about the histological spectrum of all CNS tumors in the tertiary care center serving primarily the rural population of Uttar Pradesh. Aims and objectives The present study aimed to describe the histopathological spectrum of all CNS tumors reported in a rural tertiary care center at Saifai, Uttar Pradesh. It also aimed to provide an overview of the descriptive epidemiology of CNS tumors. Material and methods This was a retrospective, cross-sectional study. The study duration was three years. A total of 115 cases of CNS tumors were studied during that period. Cases were classified according to their histological types, and results were analyzed. Results The most common histological group was neuroepithelial tumors, with 53 cases (46.08%). This group had 36 cases of astrocytic tumors (31.3%), three cases of oligodendroglial tumors (2.6%), five cases of oligoastrocytic tumors (4.34%), five cases of ependymal tumors (4.34%), and four cases of embryonal tumors (3.47%). The second most common tumor was meningeal tumors, with 32 cases (27.82%). The male/female ratio (M/F) ratio was 0.7. Females were found to be more affected by almost all histologic categories. Most meningiomas (89.6%) were of World Health Organization (WHO) grade I (26 cases out of 29). Astrocytic tumors showed WHO grade I, II, III, and IV tumors in two cases (5.5%), twelve cases (33.3%), four cases (11.1%), and eighteen cases (50%), respectively. In the younger age group (0-20 years), ependymoma and medulloblastoma were most common, followed by pilocytic astrocytoma and schwannoma. Conclusion In this region, neuroepithelial tumors were seen more commonly than meningioma. Females were found to be more affected by CNS tumors. This study has provided relevant data, which can be used for research and better patient management. Further studies with the incorporation of advanced radiological investigation and immunohistochemistry have been recommended.

Fine-needle aspiration cytology of a cesarean scar endometriosis.

Endometriosis is the presence of functioning endometrium outside the basement membrane of the uterine endometrium. It affects women of reproductive age and usually presents as a painful nodule over a period of 3 months to 10 years after surgery. Extrapelvic endometriosis is uncommon and more difficult to diagnose due to its variable presentation and is often confused with other surgical conditions. Fine-needle aspiration cytology (FNAC) is a rapid, cost-effective, and accurate diagnostic tool when making this diagnosis. Wide excision is the treatment of choice for scar endometriosis as well as for recurrent lesions. We present a case of scar endometriosis in a 30-year-old female who had undergone a cesarean section 2 years previously and was diagnosed by FNAC. A later histopathological examination confirmed the cytological diagnosis of scar endometriosis.

Cytohistopathological study of salivary gland lesions in bundelkhand region, uttar pradesh, India.

Background. FNAC is a useful method for evaluating suspicious salivary glands lesions due to its low cost, minimum morbidity, rapid turnaround time, high specificity, and sensitivity. Aim. To know the frequency of the salivary gland lesions and cytohistological correlation in the Jhansi region, Uttar Pradesh, India. Material and Methods. In present study 124 cases were included and cytohistological correlation was made in 86 cases only. FNA was performed by using a 23/24-gauge needle without local anaesthesia. Air dried and 95% ethyl alcohol fixed wet smears were stained with Giemsa stain and Papanicolaou stain, respectively. Paraffin embedded tissue sections were stained with Haematoxylin and Eosin. Results. Parotid gland was the most commonly involved salivary gland. The commonest age group was 20 to 29 years, 30 to 39 years, and 60 to 69 years for nonneoplastic lesions, benign tumours, and malignant tumours, respectively. The overall male to female ratio was 1.17 : 1. The diagnostic accuracy of FNAC was 100%, 93.3%, and 88.2% for nonneoplastic lesions, benign tumours, and malignant tumours, respectively. Conclusion. The high accuracy, sensitivity, and specificity of FNAC confirm that preoperative cytology is a useful, quick, reliable diagnostic technique for rapid diagnosis and suitable for developing countries.

Histopathological study of skin adnexal tumours-institutional study in South India.

Objective. The aim of this study was correlation of skin adnexal tumors with age, sex, and location and determining its incidence in the Department of Pathology at Dr. D. Y. Patil Medical College and Hospital, Kolhapur, Maharashtra. Material and Methods. 56 cases were included in this study from Jan 2004 to June 2010 with respect to incidence of adnexal tumors, age, and sex distribution. All slides were stained with haematoxylin and eosin and then findings were corroborated with special stains like PAS and reticulin wherever required. Results. 80.36% (45/56) were benign and 19.64% (11/56) were malignant adnexal tumors. The sweat gland tumors constituted the largest group (42.86% 24/56) cases followed by the hair follicle tumors (35.71%, 20/56) of cases and sebaceous gland tumors (21.43%, 12/56) cases. Overall male : female ratio was 1.07 : 1. The commonest age group was 51-60 years and the commonest affected body part was head and neck region (64.28%, 36/56) followed by trunk (14.28%, 8/56). Clear cell hidradenoma and pilomatricoma were commonest benign tumors and sebaceous carcinoma was the only malignant tumor seen. Conclusion. The incidence of benign skin adnexal tumors was more as compared to the malignant tumors. Malignant tumors were seen in older age group, usually over 50 years of age.

Comparative Study of Cytomorphological Robinson's Grading for Breast Carcinoma with Modified Bloom-Richardson Histopathological Grading.

Objective. To study the correlation of cytomorphological Robinson's grading for breast cancers with a modified Bloom-Richardson histopathological grading. Materials and Methods. One hundred sixteen cytologically malignant breast tumour cases were included in this study and correlated with paraffin embedded sections. Breast lumps were varied from less than 1 cm to 11 cm in greatest dimension. FNA was performed from different sites of the breast lump, and smears were stained with Giemsa and H&E stain and evaluated for cytological grading according to Robinson's grading system. Paraffin embedded tissue sections were stained with hematoxylin and eosin stain and graded according to modified Bloom-Richardson grading system. Comparison between these two grading systems was done. Results. Cytologically grade I, grade II, and grade III cases were 13.8%, 64.65%, and 21.55%, respectively. Histologically 25%, 54.31%, and 20.69% cases were grade I, grade II, and grade III, respectively. Concordance rate between cytology and histology of grade I, grade II, and grade III tumors was 75%, 70.67%, and 60% respectively. The absolute concordance rate was 68.97%. Conclusion. In the era of multiple treatment modalities and neoadjuvant therapy, cytological grading can be used as a prognostic factor for better management of patients.
