The metaplastic breast carcinoma is a rare malignancy with an incidence of 5% of all breast tumors. Metaplastic carcinoma of the breast with mesenchymal differentiation (MCMD), previously known as carcinosarcoma, is a very rare and aggressive tumor that has been recently classified as a subtype of metaplastic breast carcinoma. It accounts for 0.08%–0.2% of all breast cancers, with only a few cases reported in the literature. Metaplastic breast carcinoma most often affects women over 50 years of age, with an average age between 55 and 60 years. We report three cases of metaplastic breast carcinoma with mesenchymal differentiation presented at our hospital. Patients were in their 4th decade. All patients presented with a fast-growing large mass and were treated surgically (mastectomy), with the final histopathological diagnosis of MCMD. [ABSTRACT FROM AUTHOR]

Introduction: In India, prostate carcinoma is the fifth most common cause of carcinoma in men, and the fourth in cancer mortality. Incidence of prostate malignancy is increasing in India by one percent every year. Prostate carcinoma is graded using the Gleason scoring system. The Gleason score is very useful for predicting the prognosis of prostate carcinoma. The collaborative use of clinical features, combined with the size of the prostate, prostate-specific antigen levels, and histopathological features helps in making an accurate and early diagnosis of the patients. Material and Method: This present prospective study included all histologically proven cases of prostate carcinoma in the Department of Pathology, Guru Gobind Singh Medical Hospital over a period of one year. A detailed histopathological examination of the H and E stained sections is carried out under light microscope including histological typing, Gleason scoring and grading. The Gleason grade was correlated with serum PSA levels. Results: Out of 80 cases, 28 (35%) were reported as Gleason grade group 3 with a Gleason score of 7 (4 + 3). 12 cases (15%) showed a Gleason grade group 2 with a Gleason score of 7 (3 + 4). Grade group 4 (Gleason score 8) and grade group 5 were observed in 22 cases (27.5%) and 18 cases (22.5%), respectively. Whereas, no case of Gleason grade group 1 with Gleason score of 6 (3 + 3) was seen. Conclusion: Gleason's Group Grade 3 outnumbered all the group grades, contributing 35% (28 cases) of the total cases of prostatic adenocarcinoma. Serum PSA levels were raised (>10 ng/ml) in 100% of cases. Henceforth, it signifies the importance of serum PSA levels in prostate carcinoma. Lymphovascular invasion was associated with higher group grade of prostatic adenocarcinoma. [ABSTRACT FROM AUTHOR]
