Diffuse pleural metastasis from atypical meningioma.

Meningioma is the most common benign primary brain tumour and does not usually metastasise. We report the case of a 69-year-old male patient with a history of meningioma who presented respiratory symptoms. He was found to have diffuse pleural metastasis from meningioma, which occurred 10 years after surgical management of recurrent meningioma.

An interpretable decision-support model for breast cancer diagnosis using histopathology images.

Microscopic examination of biopsy tissue slides is perceived as the gold-standard methodology for the confirmation of presence of cancer cells. Manual analysis of an overwhelming inflow of tissue slides is highly susceptible to misreading of tissue slides by pathologists. A computerized framework for histopathology image analysis is conceived as a diagnostic tool that greatly benefits pathologists, augmenting definitive diagnosis of cancer.

Fall in Ki67 Index After Short-Term Preoperative Letrozole: a Gateway to Assess the Response in Hormone-Positive Early Breast Cancers.

Endocrine treatment for breast cancer acts largely by inhibiting tumor cell proliferation. The study aimed to explore the fall in proliferative marker Ki67 in patients receiving preoperative endocrine therapy and the factors associated with it. A prospective series of hormone receptor-positive postmenopausal women with early N0/N1 breast cancer were enrolled.

Unchartered waters: Significance of fall in Ki67 index after short-term preoperative endocrine therapy in early breast cancers.

Background: Endocrine treatment for breast cancer acts largely by inhibiting tumor cell proliferation. The biomarker Ki67 is linked to the proliferative index of the tumour.

Objective: To identify the factors affecting the fall in Ki67 value in early-stage hormone receptor (HR) positive breast cancer patients receiving short-term preoperative endocrine therapy in an Indian cohort.

Utility of Fluorine-18-Labeled Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in Diagnosis of Erdheim-Chester Disease with Multisystemic Involvement.

Erdheim‒Chester disease (ECD) is a rare non-Langerhans' cell histiocytic proliferative disorder of unknown origin with multisystemic predilection. It commonly affects adults in the fifth-seventh decades of life, with male preponderance, and has nonspecific clinical manifestations. Presence of characteristic radiological findings and demonstration of CD68 positive xanthogranulomatous infiltrates in histology clinches the diagnosis.

Recurrent DHA nephropathy in renal allograft-revisiting clinicopathological aspects of a rare entity.

Background: Adenine phosphoribosyltransferase (APRT) enzyme deficiency is a rare autosomal recessive disorder of purine metabolism affecting mainly the kidneys. It can present at any age with varying degrees of acute and chronic renal damage. Though xanthine dehydrogenase inhibitors offer effective control over the disease process, delay in diagnosis and treatment often lead to compromised function of native and even graft kidneys.

Disseminated gastric carcinoma in disguise-presentation as microangiopathic haemolytic anemia with bone marrow necrosis.

Cancer related microangiopathic hemolytic anemia (MAHA) and bone marrow necrosis (BMN) are two rare and distinct clinicopathological entities reported in patients with disseminated malignancy. When they emerge as initial findings in a previously undetected case of malignancy, the diagnosis is often missed resulting in inappropriate management. We report the extremely rare association of cancer related MAHA and BMN as the first presentation of unsuspected disseminated gastric carcinoma in a 63 years old male.

Primary granulosa cell tumor of retroperitoneal origin: A rare presentation with emphasis on cytomorphology.

The most frequently occurring retroperitoneal tumors are those of the kidneys, adrenal glands, and the pancreas. A primary retroperitoneal tumor composed of granulosa cells and developing far away from the normal location of the ovary is less frequently observed. A 69-year-old female patient presented with abdominal discomfort.

Primary cardiac sarcoma with metastases to thyroid and brain.

Primary cardiac sarcomas are extremely rare with only a few large case series and isolated case reports in the literature. In spite of their aggressive nature with high chances of local recurrence and distant metastases, these tumors and their treatment strategies remain incompletely defined. We report an unsuspected case of primary cardiac pleomorphic undifferentiated sarcoma in a 52-year-old female who presented with progressive dyspnea and palpitation.
