RESUMO
Background & objectives: Thymomas are rare, but most common anterior mediastinal lesions. The histomorphologic spectrum of thymic epithelial tumours (TETs) in Indian population has not been explored in depth. This study was aimed to assess the histomorphology of TETs in the Indian patients and correlate clinical parameters with pathological features. Methods: It was a retrospective study conducted in a tertiary referral hospital in north India. All morphologically confirmed cases of TETs since 2009 were included. Clinical details and histology slides were reviewed using the Modified Masaoka-Koga staging system and WHO 2015 classification. Clinicopathological correlation and survival analysis were done. A comparative review from other published Indian studies was performed. Results: A total of 219 cases of TETs (138 resections and 81 biopsies) were identified. The most common histomorphologic type was B2, and the most frequent stage was I. Types A/AB were common in older age (P<0.01). Clinically, higher stage tumours were found mostly in men (P<0.01), and these were Type B thymomas (P<0.01). Myasthenia gravis was more common in women (P<0.02) and in lower stages (P<0.05). Survival analysis revealed significant association between recurrence and tumour stage. Although thymic carcinoma was diagnosed on biopsy, no resectable case was identified. Interpretation & conclusions: Our findings showed that the thymomas in Indian patients were most commonly Stage I tumours of B2 and AB histotypes. Resected thymic carcinomas were conspicuously absent in our study. More studies need to be done to establish the frequency and biology of TETs from India.
RESUMO
Background: Ovarian tumours are a heterogeneous neoplasm with a varied clinical, morphological and histological feature. Increasing mortality rate due to ovarian cancers has been reported in recent years. Ovarian tumours in post-menopausal females have high risk of malignancy and it has a very poor outcome. The aim and objective of this study was to determine clinical and histopathological spectrum and the frequency and age distribution of various ovarian tumors.Methods: It is a retrospective observational study of patients with ovarian tumors in the department of obstetrics and gynecology, SGRRI of Medical Health & Sciences and Hospital from January 2016 to December 2017 in a total number of 86 patients. All specimens were sent to pathology department and categorised according to WHO hispathological classification.Results: Out of 86 cases examined, 64 cases were benign (74.4%), 3 cases were borderline (3.4%) and 19 cases were malignant (22.2%). Majority of the ovarian tumors (73.4%) were seen in the age group of 20 to 50 years. Most commonly encountered benign ovarian tumour was serous cystadenoma (58.1%). Surface epithelial tumors were the commonest tumors (64%) followed by germ cell tumors (29%).Conclusions: A variety of benign and malignant tumours of ovary were reported in this study. Early diagnosis and appropriate treatment of ovarian neoplasms favour the good prognosis. Most common benign tumour encountered in this study was serous cystadenoma.
