Killing Two Birds With One Stone: Successful Management With Rituximab in the Coexistence of Myasthenia Gravis and Marginal Zone Lymphoma.

Myasthenia gravis (MG) is an autoimmune neuromuscular disorder characterized by motor weakness affecting various muscle groups. The simultaneous or sequential occurrence of lymphoma and MG, often seen in patients, could be influenced by common genetic and biological factors that drive unregulated lymphocyte growth, leading to autoimmunity and lymphoma. This case report describes a 72-year-old male with coexisting marginal zone lymphoma and MG, who exhibited a positive response to rituximab treatment intended for the lymphoma, but surprisingly effective for both conditions.

Failure to Confirm Typical Echocardiographic Findings of Cardiac Amyloidosis in an Unresolved Nonischemic Cardiomyopathy Associated With Smoldering Multiple Myeloma: A Case Report.

Amyloidosis is a leading cause of infiltrative cardiomyopathy and in turn heart failure with preserved ejection fraction. Amyloidosis is mainly classified into amyloid light chain (AL) or primary amyloidosis and transthyretin amyloidosis (ATTR) that is subdivided into wild-type ATTR (ATTRwt) and hereditary or familial transthyretin-related amyloidosis (hATTR). Moreover, strain preservation pattern in the left ventricular apex in echocardiography suggests cardiac amyloidosis and cardiac magnetic resonance (CMR) could identify an infiltrative process.

Pembrolizumab-Induced Hypothyroidism: A Case Report.

Pembrolizumab is a monoclonal antibody frequently used as immunotherapy for lung cell carcinoma that has been reported to cause hypothyroidism and myasthenia gravis among other, unwanted side effects. Here, we present an interesting case of a 77-year-old male previously diagnosed with lung adenocarcinoma managed with pembrolizumab. Initially, he was admitted after a mechanical fall sustaining a facial laceration and subacute fracture in the nasal bone.

Chest Pain Caused by Thoracic Spine Plasmacytoma: A Case Report.

We present a case of a thoracic mass causing chest pain that was initially attributed to coronary artery disease due to his comorbidities. However, during the Lexiscan stress test, a thoracic spinal mass was incidentally found. This case showed the importance of being cognizant of other causes of chest pain and a rare presentation of multiple myeloma.

Renal Infarction From Over-the-Counter Testosterone Booster Pills: A Case Report.

Renal infarction is a challenging diagnosis that usually requires a high level of clinical suspicion because its clinical presentation is often attributed to more frequent causes. Here, we present the case of a young male with right flank pain. A computed tomography (CT) of the abdomen ruled out nephrolithiasis; hence, a CT urogram was performed, which revealed an acute right kidney infarction.

Portal Vein Thrombosis Extending to the Superior Mesenteric and Splenic Veins Secondary to a Hypercoagulable State Due to Prior Abdominal Surgery, Hormonal Replacement Therapy, and Flaxseed Consumption.

Herein is a case of a 50-year-old male diagnosed with a non-cirrhotic acute portal vein thrombosis (PVT). Acute PVT is a rare condition usually presenting in cirrhotic patients. This patient had no past medical history of cirrhosis or hypercoagulable status and no past family history of a hypercoagulable disorder.
