Concurrent Primary Gastric and Pulmonary Diffuse Large B-Cell Lymphoma: A Case Report and Literature Review.

The primary pulmonary diffuse large B-cell lymphoma (PPDLBCL), a kind of non-Hodgkin's lymphomas, itself is a rare entity. Its association with primary B-cell gastric lymphoma has not been established yet. Herein we present a case of PPDLBCL along with a literature review.

Nodular Esophageal Xanthoma: A Case Report and Review of the Literature.

Xanthomas are localized nonneoplastic lesions within tissues that may manifest as papules, plaques, or nodules. These lesions can be found anywhere along the gastrointestinal tract, commonly in the stomach and colon, and rarely in the small intestine and esophagus. Esophagogastroduodenoscopy (EGD) with biopsy is the gold standard tool for diagnosis.

Autopsy report with clinical and pathophysiologic discussion of autosomal dominant adult polycystic kidney disease.

The average weight of a kidney is approximately 135 gm, measuring on average 10 × 6 × 4 cm. In hereditary conditions, autosomal dominant and autosomal recessive polycystic kidney disease, the shape, size, and the weight can be significantly abnormal, causing progressive renal failure, often necessitating dialysis or renal transplant for survival. We report a case of adult polycystic kidney disease in a 50-year-old female without a family history, who died of complications of the disease which included accelerated hypertension, and renal and cardiac failure.

Esophageal plasmacytoma diagnosed in a patient presenting with cardiac symptoms: a novel case.

Extramedullary plasmacytoma is the uncommon phenomenon of a plasma cell neoplasm occurring outside of the bone marrow. Primary plasmacytoma is a rare occurrence in the gastrointestinal tract and exceptional to originate in the esophagus. We present a novel case of a 62-year-old man who presented to our emergency department with chest pain.

Angiosarcoma of small bowel presenting with obstruction: novel observations on a rare diagnostic entity with unique clinical presentation.

We present a case of angiosarcoma in small bowel, presenting with partial small bowel obstruction in a 79-year-old man with no history of radiation, chemotherapy, toxin exposure, or previous operative intervention. Angiosarcoma of small bowel is a rare entity which may present with nausea, abdominal pain, recurrent bleeding, and usually a history of prior radiation or exposure to specific toxins (polyvinyl chloride). Angiosarcoma of small bowel tends to spread rapidly and has a poor prognosis.

Renal pelviceal keratinizing squamous metaplasia with sparing of pyramidal zones.

Metaplastic changes in the urothelium of the upper urinary tract are relatively infrequent. Metaplasia may present as either squamous or less often glandular differentiation. The process may be associated with chronic inflammation or associated chronic infections.
