Repurposing anticancer drugs for COVID-19-induced inflammation, immune dysfunction, and coagulopathy.

Three cardinal manifestations of neoplasia, namely inflammation, immune dysfunction, and coagulopathy are also seen in patients with severe SARS-CoV-2 infection, providing a biological rationale for testing selected anticancer drugs for their ability to control the symptoms and/or modify the course of COVID-19.

An Appraisal of Proliferation and Apoptotic Markers in Papillary Thyroid Carcinoma: An Automated Analysis.

Introduction: Proliferation and apoptosis are opposing processes by which the cell numbers are kept in a delicate balance, essential for tissue homeostasis, whereas uncontrolled growth of cells is a hallmark of cancer. Papillary thyroid cancer (PTC) is the commonest type of thyroid cancer, with some PTC following an indolent course, whereas the other ones are more aggressive.

Aim: To evaluate respective contribution of proliferation and apoptosis in the tumorigenesis of PTC by automated analysis.

Cyclin D1 in well differentiated thyroid tumour of uncertain malignant potential.

Background: Encapsulated follicular tumours with equivocal papillary thyroid carcinoma (PTC) type nuclear features continue to remain a challenge despite the recent attempts to classify these borderline lesions. The term 'well differentiated tumour of uncertain malignant potential (WDT-UMP)' was introduced to classify these tumours. The present study aimed to evaluate the role of a cell cycle regulator like cyclin D1 in these tumours along with assessment of other well established PTC markers like galectin-3, HBME-1, CK19.

Malignant myoepithelioma of the breast: case report with review of literature.

Myoepithelial lesions of the breast are extremely rare and can present with a diverse morphology. We report a case of malignant myoepithelioma characterized by proliferation of atypical oval to polygonal cells expressing typical myoepithelial markers. A 45-year-old lady presented with a mass in the left breast.

Primary leiomyosarcoma of the kidney.

Primary leiomyosarcoma of the kidney is a rare tumor with an aggressive behaviour. A 55-year-old woman presented with a left sided abdominal mass in our outpatient department. Radiologic investigations revealed the mass to be renal in origin with colonic adhesions for which radical nephrectomy and hemicolectomy were done.
