Stewart-Treves syndrome (STS) is defined as the development of cutaneous angiosarcoma in the presence of long-standing lymphedema and is a rare disease with only about 400 cases reported in world literature. We report a case of a 63-year-old morbidly obese woman with a long-standing history of lymphedema who developed angiosarcoma of the right lower extremity with metastasis and presented with acute respiratory distress. The patient underwent a thorough laboratory workup with a chest X-ray showing bilateral effusions. The hematology-oncology service was consulted and found the patient to have significant progression of angiosarcoma causing respiratory failure and cardiac instability. A decision to transition to hospice care was made and the patient eventually passed away in the intensive care unit. We present this case to raise awareness of STS in medical literature to understand its clinical manifestations better. Early detection is imperative as angiosarcoma is commonly an aggressive disease.
Swallow or deglutition syncope is an uncommon cause of syncope associated with bradyarrhythmia and hypotension during food swallowing. Early recognition of this condition is imperative but challenging. We report a case of a 60-year-old female who presented with a complaint of intermittent lightheadedness after swallowing food. An episode of presyncope was observed and a reduced pulse rate from baseline was noted when she was instructed to eat a candy bar in the clinic. Further workup revealed normal inoffice electrocardiogram, bilateral carotid ultrasound, transthoracic echocardiogram, and videofluoroscopic swallow study. Our goal in presenting this case is to raise awareness of the condition in medical literature and provide a good understanding of its clinical manifestation to prevent life-threatening events.
Giant bullous emphysema, also known as "vanishing lung syndrome", is a rare manifestation of chronic obstructive pulmonary disease (COPD) that is associated with high mortality. Cigarette smoking and alpha-1 antitrypsin deficiency (A1AD) are two main causes that result in permanent enlargement of airspaces, inefficient gas exchange, fibrosis of the airways, and collapse of the alveoli. A typical presentation can be found in a long-term smoker with dyspnea on exertion and progressive shortness of breath that may be associated with a productive cough. One of the clinical difficulties in diagnosing giant bullous emphysema is separating it from other etiologies like pneumothorax. It is paramount to differentiate giant bullous emphysema from pneumothorax as the management is completely different; both can, however, have similar clinical presentations and radiographic manifestations on initial assessment. In this report, we present the case of a 39-year-old African American male who presented with worsening shortness of breath and productive cough and was found to have bullous emphysema but was misdiagnosed and treated for pneumothorax in the initial encounter. The purpose of this case report is to raise awareness of this condition in the medical literature and discuss the similarity of bullous emphysema and pneumothorax in clinical presentation and radiographic findings, as well as the differences in treatment options.
Nivolumab is a checkpoint inhibitor approved to treat various solid organs malignancies. Although checkpoint inhibitors are very efficacious, these medications are also associated with a variety of side effects that could be life-threatening. We present a case of nivolumab-induced myasthenia gravis in a patient with stage IV esophageal cancer, who was found to have generalized weakness, blurry vision, diplopia, and later developed acute hypoxic respiratory failure with subsequent intubation. The patient was treated with intravenous immunoglobulin and plasmapheresis, and later started on pyridostigmine and high-dose steroids with minimal improvement. Goals of care were discussed with the patient and family, and the decision was made to discharge the patient home with hospice care. Nivolumab-induced myasthenia gravis is very aggressive with a poor prognosis if not appropriately managed in time. Hence we strongly recommend a multidisciplinary approach, including neurologists, to monitor patients on nivolumab therapy to reduce morbidity and mortality associated with it.
Chronic intestinal pseudo-obstruction (CIPO) is a rare, potentially debilitating gastrointestinal (GI) condition characterized by symptoms of intestinal obstruction with the absence of anatomic lesions. In this report, we present a case of an 86-year-old female who presented with severe abdominal discomfort, nausea, and vomiting for two weeks prior to presentation. Imaging studies revealed severe gastric distension with a lack of anatomic lesions. The patient was ultimately diagnosed with chronic idiopathic intestinal pseudo-obstruction (CIIP). The purpose of this case report is to raise awareness of this condition in the medical literature and discuss the epidemiology, pathophysiology, clinical manifestations, diagnostic workup, and treatment options of this disorder.
Renal cell carcinoma (RCC) is the most common neoplasm that arises from renal parenchyma. About onethird of patients with RCC develop metastatic spread, with common sites including the lung, liver, bone, adrenal gland, and brain. Distant metastases can be difficult to detect unless symptoms appear. We report a case of a 56-year-old female who presented to the emergency department with the unresponsiveness of unknown duration. She underwent a thorough laboratory workup, and the computed tomography (CT) scan revealed a retroperitoneal mass originating from the right kidney and a large hemorrhagic brain mass in the left frontal lobe. The patient underwent emergent full craniotomy for tumor removal, and histology confirmed metastatic RCC. Since several patients with RCC are asymptomatic, the slow growth of tumors leading to distant metastasis can be overlooked. Thus, this case demonstrates the importance of early detection of RCC to help prevent or delay further disease progression.
