Extra-adrenal pheochromocytoma is rare and presents variable symptoms. Its difficulty to diagnosis delays appropriate treatment. We would like to report an unusual case of extra-adrenal pheochromocytoma. The patient came to the emergency room with dyspnea, palpitation, and cyanosis. He had a history of hospitalization for Fontan operation due to congenital heart disease. Despite medication, his...

Phaeochromocytomas (PHEOs) and paragangliomas (PGLs) are catecholamine-secreting tumors, that arise from chromaffin cells of the adrenal medulla and extra-adrenal sites. Extra-adrenal phaeochromocytomas are called paragangliomas (Landers et al., 2005). The Prevalence of these tumors is 1:4500 and 1:1700 and an annual incidence of 3-8 cases per 1 million per year in the general population. PHEOs...

BACKGROUND Extra-adrenal myelolipomas are rare benign tumours. Other soft tissue tumours such as well-differentiated liposarcomas appear morphological almost identical. Preoperative imaging and especially biopsy are important tools to diagnose these lesions. CASE PRESENTATION We report a very seldom case of a simultaneous myelolipoma of the adrenal gland in association with an extra-adrenal m...

Extra-adrenal pheochromocytomas are rare tumors that originate from the chromaffin tissue of the sympathetic nervous system. Ovarian extra-adrenal pheochromocytoma is even more rare. The present study reports a rare case of an extra-adrenal pheochromocytoma that was localized to the right ovary, but was gynecologically asymptomatic. Computed tomography angiography (CTA) detected the tumor and i...

Myelolipoma of the adrenal gland is a rare, benign and biochemically inactive tumor comprising mature fat and hematopoietic elements. Most of these lesions are discovered incidentally. The vast majority occurs within the adrenal glands, but extra-adrenal myelolipomas have also been reported. The typical extra-adrenal myelolipoma is a solitary, well-defined mass with in abdomen. We present a 70 ...

Myelolipoma is an uncommon benign tumour composed of mature fat tissue and haematopoietic elements and is most commonly found in the adrenal gland. We report a case, which was discovered incidentally on chest X-ray, of a rare occurrence of multifocal extra-adrenal myelolipoma in the thoracic paravertebral region. This was further investigated with multi-detector computed tomography and magnetic...

The Paraganglioma is the most common extra-adrenal pheochromocytoma arising from neural crest (1) (It will better to write: The paraganglioma is an extra-adrenal pheocromocytoma arising from the neural crest. 10% of pheocromocytomas are extra-adrenal and can arise form chromaffin tissue derived from primitive neuroectoderm). Minimally invasive techniques allow surgeons to perform the procedure ...
