Plasma cell leukemia in a 34-year-old male: rare scenario case report.

Introduction: Plasma cell leukaemia is an uncommon plasma cell dyscrasia with a very poor prognosis. It is more common among males and usually presents between 55 and 65 years of age. Case presentation: A 34-year-old male presented to Al-Assad hospital with unremitting back pain. He was given analgesics but his pain was unresponsive to treatment, and due to the COVID-19 pandemic, he refused a computed tomography scan in the hospital. Later that year, he presented again with weight loss, nausea, abdominal pain, melena, and ascites. He was pale with a moderately distended abdomen. Laboratory tests revealed anaemia, thrombocytopenia, hypercalcemia, increased total proteins, and elevated lactate dehydrogenase. Flow cytometry findings of the bone marrow aspirate showed the presence of 30% of plasma cells, positive for CD38, CD56, and kappa light chains. He was diagnosed with secondary plasma cell leukaemia and started on chemotherapy; however, he could not continue his treatment due to myeloid inhibition. He passed away 5 months later. Clinical discussion: Multiple myeloma was not suspected in the patient due to his young age. The diagnosis was delayed even further due to the COVID-19 pandemic. His multiple myeloma progressed into secondary plasma cell leukaemia and had uncommon features like small intestinal polyps. Even though there has been groundbreaking advancements in chemotherapy, plasma cell leukaemia still possesses a fatal prognosis. Conclusion: This report showcases a rare age presentation with unique manifestations of secondary plasma cell leukaemia. Multiple myeloma should be a differential diagnosis for cases with unexplained back pain despite an unclassical age.

Gastric lipoma in the pyloric antrum: a rare case report.

Introduction and importance: Gastric lipoma (GI) is a rare benign tumor of the stomach that arises from adipose tissue. It is often asymptomatic and is incidentally diagnosed on endoscopy or imaging studies. Case presentation: A 66-year-old male presented with epigastric pain and acid reflux. Upper gastrointestinal endoscopy revealed a 3-cm submucosal lesion in the pyloric antrum. The patient underwent a subtotal gastrectomy. The specimen was sent to the pathology department. Based on the microscopic findings, the diagnosis was a submucosal GI. Discussion: The diagnosis of GIs is usually made incidentally during imaging studies. Treatment options include endoscopic or surgical resection; however, conservative management can be considered in asymptomatic patients. Periodic radiological surveillance is recommended to monitor growth and assess for any malignant transformation. Conclusion: GI is a rare tumor that is usually asymptomatic but can present with nonspecific gastrointestinal symptoms. The diagnosis is confirmed through histological examination, and imaging techniques such as computed tomography or MRI can be useful in preoperative evaluation. Surgical resection remains the primary treatment, while endoscopic resection may be considered in certain cases.

Whorling-sclerosing meningioma invading skull bone and subcutaneous tissue with an incidental toxoplasmosis: A case report.

Whorling-sclerosing meningioma (WSM) is a rare type of meningothelial tumor. Worldwide, only 31 cases have been reported. The diagnosis of this rare meningioma subtype is based principally on microscopic findings, wherein up to 70% of the tumor tissue should be formed by thick whorls of collagen. Notably, there is still disagreement about whether to consider this entity a benign meningioma (grade 1) or a meningioma with higher malignant potential (grade 2 or even grade 3). In fact, the paucity of reported WSM cases and, consequently, the lack of information about their follow up make their diagnosis and treatment challenging. Herein, we document the first case of WSM in Syria in a 75-year-old woman with an incidental finding of Toxoplasma gondii. Although WSM has not been mentioned in the recent World Health Organization classification of central nervous system tumors, it should be recognized to avoid incorrect diagnosis and spare the patients unnecessary radiotherapy and chemotherapy.

Diagnostic challenge of a cystic solid pseudopapillary tumor in pancreas: A case report.

A solid pseudopapillary tumor should be included in the differential diagnosis of every pancreatic cystic lesion. A constellation of microscopic morphology and immunohistochemistry, in addition to the clinical history, aids in reaching the correct diagnosis.

Mesenteric inflammatory myofibroblastic tumor as a rare cause of small intestinal intussusception.

Inflammatory myofibroblastic tumor (IMT) is an uncommon, usually benign, mesenchymal tumor. IMT affects people of all ages, but it more commonly occurs in children and adolescents. Also, it has the potential to arise in any part of the body, though, it frequently develops in the lungs and mesentery. In this report, we discuss a rare clinical manifestation of mesenteric IMT presented as intussusception of the small intestine in a 7-year-old child.
