Cardiac Angiosarcoma With Pulmonary Metastasis: A Rare and Challenging Case.

Cardiac angiosarcoma is a rare and aggressive malignant tumor arising from the endothelial cells of the heart. It accounts for only a small fraction of all cardiac neoplasms and has a poor prognosis. We present a challenging case of a 20-year-old student who presented exertional dyspnea, palpitation, and occasional chest discomfort. Her clinical picture, radiological and pathological investigations confirm the diagnosis of cardiac angiosarcoma with pulmonary metastasis. This case highlights the importance of early diagnosis and multidisciplinary management for improved patient outcomes.

Takotsubo Cardiomyopathy: A Possible Rare Complication of Guillain-Barré Syndrome.

Dysautonomia is a common and severe complication of Guillain-Barré syndrome (GBS), which may manifest as cardiac arrhythmias, labile blood pressure, diaphoresis, and changes in gastrointestinal motility. Takotsubo cardiomyopathy (TCM) is a life-threatening manifestation of dysautonomia in patients with GBS, which is not widely underlined in the literature. The association between GBS and TCM has been well-documented in previous studies; however, there are few reported cases with GBS who developed TCM following their diagnosis with GBS. In this case report, we will discuss our experience treating a 59-year-old female patient who became hemodynamically unstable while recovering from an acute GBS infection. She was diagnosed with TCM after undergoing an echocardiogram and coronary angiogram ruling out thrombotic or obstructive coronary disease and myocarditis.

Dermoid Cyst Spillage Resulting in Chemical Peritonitis: A Case Report and Literature Review.

A dermoid cyst, also called a mature teratoma, is a benign tumor of the ovary derived from pluripotent germ cells. It is often asymptomatic; however, it can be expressed by several complications, including infection, adnexal torsion, and rupture. Rarely ovarian dermoid cysts can also transform into malignant degeneration. A ruptured teratoma is a rare and life-threatening complication and may arise spontaneously. However, cystic rupture is often secondary to surgical procedures such as ovarian cystectomy, leading to acute peritonitis and surgical emergency. Herein, we report a case of acute peritonitis in a female resulting from ovarian dermoid cyst spillage. Her clinical picture and radiological imaging were consistent with a ruptured ovarian cyst leading to chemical peritonitis, and a histopathological examination confirmed an ovarian dermoid cyst.

Immune Thrombocytopenia Induced by Helicobacter pylori Infection: A Case Report and Literature Review.

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by the production of autoantibodies against the platelet surface antigens. ITP is a diagnosis of exclusion and is further categorized into primary and secondary ITP. The etiology of primary ITP is idiopathic, and secondary ITP is caused by infections and autoimmune disorders. Among infectious etiology of ITP, human immunodeficiency virus, herpes virus, and hepatitis B and C virus are common. Helicobacter pylori (H. pylori) is a rare cause of ITP, and the relationship between ITP and H. pylori is highlighted in the literature. We report a case of ITP in an adult female who presented with hematemesis and petechial rash in the lower limbs. Her initial laboratory results demonstrated thrombocytopenia, and the results of her gastric biopsy and stool antigen were positive for H. pylori. She was diagnosed with ITP induced by H. pylori because additional causes of ITP were not identified. Her clinical improvement and platelet recovery after initiating H. pylori eradication therapy were consistent with H. pylori-induced ITP.

Clopidogrel-Associated Interstitial Lung Disease: A Case Report and Literature Review.

Clopidogrel is an antithrombotic agent widely used for the secondary prevention of cerebrovascular and cardiovascular complications. Clopidogrel can cause serious adverse events, including gastrointestinal bleeding. Pulmonary complications caused by clopidogrel are not widely described, and clopidogrel-induced interstitial lung disease (ILD) is rare. Here, we report a case of drug-induced ILD in a patient who presented with dyspnea, chest pain, and mild fever. The patient underwent percutaneous coronary intervention two months ago and was commenced on clopidogrel. He was diagnosed with clopidogrel-induced ILD based on clinical and imaging findings, history of drug exposure without any change, exclusion of other respiratory disorders, and clinical improvement after discontinuation of clopidogrel and steroid use.

Antineutrophil Cytoplasmic Antibody (ANCA)-Associated Renal Vasculitis After COVID-19 Infection: A Case Report.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a class of autoimmune diseases that can cause kidney failure because of mononuclear cell infiltration and the destruction of small and medium-sized blood vessels. Coronavirus disease 2019 (COVID-19) may trigger or exacerbate autoimmune diseases. We present a case of ANCA-associated vasculitis in a patient with rheumatoid arthritis after a COVID-19 infection, who presented with intermittent hemoptysis and dyspnea and was diagnosed with COVID-19 pneumonia three weeks ago. Her clinical, radiological, and serological picture was concerned with pulmonary-renal syndrome. Her serum was positive for antinuclear antibody and ANCAs, and renal biopsy showed pauci-immune crescentic glomerulonephritis. She was diagnosed clinicopathologically with pauci-immune glomerulonephritis in the setting of rheumatoid arthritis (RA) after a COVID-19 infection. Her condition improved after she was treated with rituximab and pulse dose methylprednisolone.
