Pheochromocytoma is one of the surgically curable hypertensive diseases and can arise wherever chromaffin cells are located. Herein, a case of extra-adrenal pheochromocytoma developed in a 51 year-old male is presented with brief review of literatures.

Pheochromocytoma is one of the surgically curable hypertensive syndrome and may arise wherever chromaffin cells are located. A case of a left large adrenal pheochromocytoma developed in a 49 year old male is presented with brief review of literatures.

Pheochromocytoma stems from the chromaffin cell and mostly is located in the adrenal medulla. It is an important cause of secondary hypertension due to correction of hypertension by a resection of the tumor. Because it produces and secretes catecholamine, it bothers anesthesiologists with excessive hypertension, tachycardia and arrhythmia during the anesthetic period. Therefore, anesthetic management is directed to avoid these conditions. We report a case of bilateral pheochromocytoma successfully managed intraoperatively with an infusion of nicardipine and an intermittent esmolol injection.

Pheochromcytomas are comparatively rare and arise wherever chromaffin cells are located Approximately 10-15% have been found outside the adrenal gland. A case of extra-adrenal pheochromocytoma which occurred in a 38-year-old woman is presented with review of the literature.

Paraganglioma is an extraadrenal pheochromocytoma originating from chromaffin cells distributed in the sympathetic nervous systems. Functioning extraadrenal paragangliomas represent more than 10% of all pheochromocytomas, and seems to be highly malignant tumor in comparison to intraadrenal pheochromocytomas. Recently, we experienced a case of a paraganglioma in the posterior mediastinum. A 32-year-old woman was admitted to hospital due to dyspnea on exertion, and intractable hypertension. A chest X-ray showed a well-defined mass density on the right cardiac border, and biochemical studies showed characteristic findings of pheochromocytoma. A solitary pheochromocytoma was located in the posterior mediastinum using 131I-MIBG scintigraphy. The clinical manifestations, including hypertension and dyspnea were improved after operation.

Pheochromocytomas are neoplasms of the adrenal gland that are derived from chromaffin cells. One of the most important features of this tumor is that it can synthesize and release catecholamines such as norepinephrine and epinephrine. Due to this, arterial hypertension is one of the most common manifestations of the tumor. Although arterial hypertension is a substantial risk factor for aortic dissection, aortic dissection is actually a rare manifestation of pheochromocytoma. Here, we report a patient with pheochromocytoma who presented with acute type B aortic dissection.

Pheochromocytomas are neuroendocrine tumors of chromaffin cell that originate in the paraganglia of the adrenal medulla. Approximately 10% of pheochromocytomas are found in the extra-adrenal paraganglia and are called paragangliomas. However, cases of middle mediastinal paragangliomas are very rare. In this case, the patient presented with a voice change and a headache. A middle mediastinal soft tissue mass with marked enhancement was detected on computed tomography of the chest. The 24-hour urine catecholamine level was markedly elevated. The middle mediastinal mass was biopsied via mediastinoscopy and the resulting immunohistochemical staining was compatible with a diagnosis of middle mediastinal paraganglioma. The mass was resected surgically and the symptoms were relieved.

Pheochromocytomas can arise wherever chromaffin cells are found, and most of them(90%) are in one or both adrenal glands. But they may be located anywhere along the sympathetic chain and rarely in aberrant sites. One of the common extra-adrenal sites from which these tumors can arise is a collection of para-aortic and para-ganglion cells around the origin of the inferior mesenteric artery. We experienced a case of extra-adrenal pheochromocytoma located at the organ of Zukerkandl in a 21-year-old female patient with abdominal colic and paroxysmal hypertension, whose symptoms and blood pressure returned to normal after successful surgical excision of the tumor.

Paragangliomas are rare tumors that arise from the extra-adrenal chromaffin cells, and malignancy is defined by the presence of metastases to sites that normally lack chromaffin tissue. The main therapeutic targets are tumor reduction and control of excessive catecholamine secretion. Currently, the adjuvant therapy to surgery is radiotherapy treatment using high-dose MIBG; chemotherapy is currently evolving. We report herein a case of malignant paraganglioma with lung and spine metastasis that occurred 16 years after primary tumor excision and was treated with high dose MIBG radiotherapy and chemotherapy.

A pheochromocytoma is a neuroectodermal tumor that originates from the chromaffin cells of the sympathetic system. Typical symptoms or signs are periodic attacks of paroxysmal hypertension, spell, palpitation, headache and sweating. However, the clinical presentation is quite variable. Therefore, an atypical clinical presentation sometimes makes a diagnosis difficult. Hemoptysis as a presenting symptom is very rare in pheochromocytoma. We recently experienced a patient with diffuse alveolar hemorrhage due to pheochromocytoma. A chest PA showed diffuse consolidation and ground glass opacities in both lungs. A chest CT showed diffuse consolidation and ground glass opacities in the central, middle and lower portion predominance of the lungs, sparing the costophrenic angles and apices of the lungs. In Korea, a case of pheochromocytoma that presented initially as massive hemoptysis due to diffuse alveolar hemorrhage has not been previously reported. We report the case with a review of the literature.
