Introduction: Malignant pheochromocytomas are rare catecholamine secreting tumors; there is no definitive strategy for the treatment of malignant pheochromocytomas, especially in cases with multiple tumors.
Case Presentation: A 72-year-old woman with diabetic ketoacidosis presented with multiple malignant pheochromocytomas 16 years after undergoing adrenalectomy. After three courses of systemic chemotherapy, there was no change in the size of tumor lesions or serum catecholamine levels; surgical removal of all lesions was carried out. Eighteen months after the operation, the patient has had no recurrences and her diabetes is controlled well by oral medication.
Conclusion: Our findings indicate that complete surgical resection should be considered, even in patients with multiple malignant pheochromocytomas.

Pheochromocytoma, a type of neuroendocrine tumor, can cause numerous symptoms and signs similar to those of other clinical conditions, with the classic triad being palpitations, headache, and diaphoresis. Patients with pheochromocytoma can present with various cardiac complications, including myocarditis, acute coronary syndromes, cardiomyopathy, heart failure, and arrhythmias. Here we report a case of pheochromocytoma that first presented with bidirectional ventricular tachycardia.

Background: Heterotaxy syndrome is a rare congenital condition characterized by abnormal arrangement of thoracoabdominal organs, often associated with complex cardiac and splenic anomalies. Pheochromocytoma is a rare neuroendocrine tumor that overproduces catecholamines, leading to various complications. The co-occurrence of heterotaxy syndrome and pheochromocytoma has not been previously reported.

Von Hippel-Lindau Syndrome (VHL) is a rare, hereditary disorder characterized by the development of multiple tumors and cysts in various parts of the body due to mutations in the VHL gene on chromosome 3p25-26. Patients with VHL are at increased risk for hemangioblastomas of the brain, spinal cord, and retina, renal cell carcinomas, pheochromocytomas, pancreatic neuroendocrine tumors, and endolymphatic sac tumors. Clinical manifestations vary widely, and early diagnosis through genetic testing and regular surveillance is crucial for effective management.

Background: Neuroendocrine neoplasms (NENs) comprise a group of rare tumors originating from neuroendocrine cells, which are present in both endocrine glands and scattered throughout the body. Due to their scarcity and absence of specific markers, diagnosing NENs remains a complex challenge. Therefore, new biomarkers are required, ideally, in easy-to-obtain blood samples.
