Pheochromocytoma is a chromaffin cell neoplasm that typically causes symptoms and signs of episodic catecholamine release. Pheochromocytoma can be divided into two types: familial and sporadic. The molecular mechanisms involved in familial pheochromocytoma have been unraveled, but the detailed molecular mechanism of sporadic pheochromocytoma remains unknown. The present study thus aimed at char...

Patient: Female, 36 Final Diagnosis: Pheochromocytoma Symptoms: Anxiety • depression Medication: - Clinical Procedure: - Specialty: Oncology • endocrinology. OBJECTIVE Unusual clinical course, Mistake in diagnosis. BACKGROUND Pheochromocytoma is a rare catecholamine-producing neuroendocrine tumour...

Pheochromocytoma of the urinary bladder is often misdiagnosed as it is a rare tumor. In this report, we described a case with primary pheochromocytoma of the urinary bladder. We specifically conversed the diagnostic role of X-ray computed tomography and sonography to identify the location of tumor within urinary bladder compared to other malignant or benign tumors in the bladder, and exclude ot...

Pheochromocytoma is a rare tumour which is usually suggested by sustained or paroxysmal hypertension however the spectrum of the presentation of pheochromocytoma continues to expand and hypertension may be absent despite excess catecholamine secretion. The normotensive pheochromocytoma is a distinct entity and as in the case we report the presentation was quite unique as well as the intraoperat...

We report two cases of pheochromocytoma combined with tetralogy of Fallot who showed different clinical courses. Case 1 was a 45-year-old woman with a history of radical operation for tetralogy of Fallot at 20 years of age. She presented with sudden hypertensive attack, and was diagnosed with pheochromocytoma of the left adrenal gland. She was treated surgically, and her high plasma noradrenali...

BACKGROUND Composite pheochromocytoma/paragangliomas are very rare tumors composed of ordinary pheochromocytoma paragangliomas associated with neurogenic tumors. Several hereditary susceptibility disorders are known to be associated with pheochromocytoma/paragangliomas such as multiple endocrine neoplasia type 2 (2A or B). To the best of our knowledge, only four cases of composite pheochromocyt...

Pheochromocytoma and Ganglioneuroblastoma are separate diseases and a rare combination in which the diagnosis can only be confirmed by pathological examination after tumor excision. We reported here a case of ganglioneuroblastoma encapsulated in pheochromocytoma. The patient is a woman, 73 years old, hypertensive, with hypothyroidism, associated for 15 years with hypercholesterolemia and hypert...

The dramatic presentation of pheochromocytoma in crisis is uncommon and is classically associated with a state of hemodynamic and sympathetic hyperactivity. The case of a 35-year-old man with an occult pheochromocytoma presenting with hypotension and cardiogenic shock shortly after beginning imipramine therapy is presented. Retrospectively, there was a history of emergency department, inpatient...

Pheochromocytoma is a neuroendocrine tumor, characterized by an excess of catecholamine production, which results in paroxysmal or sustained hypertension, even hypertensive crisis. The classic triad of pheochromocytoma is paroxysmal headache, sweating and palpitation. Myocarditis is a rare manifestation of pheochromocytoma. We report 2 middle-aged women with a long history of hypertension and h...

A 63-year-old man, who was diagnosed with sudden sensorineural hearing loss (SSHL), showed severe hypertension 10 hours after prednisolone administration. Subsequently, the patient suddenly died due to pulmonary edema. The autopsy indicated a pheochromocytoma in the right adrenal gland, and the cause of death was determined to be a pheochromocytoma crisis induced by systemic administration of p...
