ABSTRACT
Aim and objectives: To show the incidence of triple negative breast carcinomas in the younger age group (20-40 years) in the study sample and to establish a correlation between expression patterns of estrogen receptor (ER), progesterone receptor (PR) and HER2 /neu with tumour histopathology of breast carcinoma. Material and methods: A 5 years study, 2 years restopective and 3 years prospective was conducted in Mahatama Gandhi Memorial hospital, Warangal, from 2009 to 2014 on triple negative breast carcinomas. All the mastectomy specimens, received in the pathology Department during this period were considered. Results: Total of 28 cases of carcinoma breast in females diagnosed histopathologically, were included in the study. In the present study, the patients were in the age group of 20-40 years Since most carcinomaS in this age group are triple negative. most of the tumours werte of size > 5 cm, 12 cases (43%), followed by 10 cases (36%) of size 2-5 cm. Total 20 (71.4%) were IDC (NOS), followed by 4 (14.2%) were Medullary carcinomas and 2 (7.1%) cases of ILC and each 1 (3.6%) case of tubular and Mucinous carcinomas. Histopathological grading was done according to Modified Bloom Richardson grading and found that 11 (39.3%) were of grade II followed by 5 (17.9%) cases were grede lll,4 cases were of grade I and 8 cases were inassessible. ER and PR were positive in 61% and 47% of tumors respectively. HER-2 over expression was seen in 36% of tumors and was negative in 64% of tumours. Triple negative carcinomas were 4 out of 28 cases, of which 3 were IDC (NOS) and 1 was medullary carcinoma. Triple negative carcinomas are associated with poor prognosis. Conclusion: ER, PR and HER-2 status correlates well with histopathological grading and other clinico-pathological parameters. Higher grade is associated with HER-2 positivity and ER/PR negativity,larger tumor size, lympho-vascular invasion, lymph node metastasis, and higher clinical stage.
ABSTRACT
Aim and objectives: To compare the conventional and the Bethesda system for reporting thyroid cytopathology (TBSRTC), to correlate the cases with histology wherever available and to determine the sensitivity, specificity and false positive rates of both the methods. Material and methods: A Total of 240 patients who presented with thyroid gland swelling were subjected to thyroid fine needle aspiration cytology (FNAC) and the smears were made followed by H&E staining and reporting was done The convential system used at our centre includes description of microscopic findings of the case along with an impression at the end. The categorization according to the Bethesda system of reporting thyroid cytology were done using criteria published in the atlas and related literature. The cytological diagnosis was correlated with the histological diagnosis wherever it was available. The sensitivity, specificity, false positive rates were calculated considering cytology as screening test for differentiating between neoplastic and non-neoplastic lesions. Results: When the results of the conventional system were compared with the Bethesda adapted method was found to be more superior. Sensitivity of Bethesda system was significantly high (100%) as compared to conventional system (77%). Specificity of Bethesda system was also significantly high (82.5%) as compared to conventional system (69%). Conclusion: Our findings were consistent with others who used the Bethesda cytopathology reporting system.
ABSTRACT
Aims and Objectives (1) To perform and interpret p53 immunostaining on the diagnosed malignant surface epithelial ovarian tumours. (2) To correlate expression of p53 with histological type of malignancy. Materials and Methods A 2-year prospective study was done i.e., from October 2011 to September 2013 on ‘A study on expression of p53 in surface epithelial ovarian tumours’ in MGM Hospital, Warangal. All the ovarian surface epithelial tumour specimens, received in the pathology department during this period were considered. Results A total of 121 cases were studied, out of which benign tumours were the most common (64.4%), followed by malignancy (25.6%) and 12 cases(10%) of borderline malignancy. Most of the benign tumours were unilateral; the cases that showed bilateral involvement were mostly malignant. The maximum number of cases in the present study was seen in the age group of 31–60 year. The youngest patient was 16 year old and the oldest was 68 year old. Serous cyst adenoma was the most common neoplasm found and accounted for 53 cases (43.8%), followed by mucinous cystadenoma, which accounted for 21 cases (17.3%). Nine cases of serous cystadenofibroma (7.43%), 3 borderline serous tumours (2.47%) and 11 serous cystadenocarcinoma (9%) were found in the present study. Out of the 44 mucinous tumours, 21 were benign (17.3%), 3 were of borderline malignancy (2.47%) and 20 were malignant (16.5%). One case of mucinous cystadenocarcinoma was found to be associated with adenocarcinoma of ascending colon. One case of benign Brenner tumour was also found in the present study. The rate of p53 abnormalities varies with histological type, grade and stage of the tumour. P53 expression was more in malignant serous tumours as compared to the malignant mucinous tumours.
ABSTRACT
Limbal squamous cell carcinoma is uncommon worldwide. Its early stages of presentation may look like the commoner limbal mass, pterygium or actinic keratosis. We report a case of invasive squamous cell carcinoma of limbusin a 45-year female patient. A high index of suspicion is required to prevent delay in the diagnosis of an invasive condition that can destroy the eye completely[1]. A rare case of squamous cell carcinoma of the conjunctiva is presented here. This highlights the significance of aggressive management of such cases surgically and the use of adjuants per operatively to prevent recurrence.
