ABSTRACT
Pheochromocytoma is a rare endocrine tumor originating from chromaffin cells of the adrenal medulla, which leads to the overproduction of catecholamines. Most symptoms, ranging from simple headaches to life-threatening cardiac arrests, are due to excess catecholamines. Usually, patients present with persistent or paroxysmal hypertension, headaches, sweating, and palpitations. Here, we describe a case that initially presented as an acute coronary syndrome and was treated accordingly. However, she had a history of nocturnal awakenings and panic attacks, which she had ignored for a month. On further evaluation, it turned out to be pheochromocytoma. This case report will surely help physicians better diagnose and treat such cases.
ABSTRACT
Hemophagocytic lymphohistiocytosis (HLH) is a rare disease that is even rarer in the adult population. It requires a high degree of suspicion from the treating physician, and if diagnosed early, patients might have a survival benefit from this highly fatal condition. HLH is a disorder of immune regulation where the hyperactivity of cytokines attacks different cells, which leads to multiple organ dysfunctions. Varying presentations and similarities with other diseases make diagnosis difficult. Familial HLH is commonly seen in the pediatric population, while acquired or secondary HLH is seen in adults. Secondary HLH is commonly triggered by neoplasms, infections, rheumatological diseases, and other autoimmune diseases. Here is a case of HLH that presented as chronic undiagnosed fever. In this case report, we have discussed in detail this disease, its presentation, investigations, treatment, and other important information that will help practicing doctors better diagnose and treat HLH patients.
