Recurrent benign adrenal pheochromocytomas associated with hemihypertrophy
UNLABELLED We report a case of a female with hemihypertrophy, who developed five recurrences of pheochromocytomas until the age of 35. Timely follow-up of the patient's blood pressure assisted in early diagnosis and treatment of recurrent tumors. LEARNING POINTS Recurrent benign pheochromocytomas should raise suspicion of a genetic syndrome.A pheochromocytoma at a young age has a high propens...
متن کاملIntra-tumoral molecular heterogeneity in benign and malignant pheochromocytomas and extra-adrenal sympathetic paragangliomas.
Pheochromocytomas (PCCs) and extra-adrenal sympathetic paragangliomas (sPGLs) are catecholamine-producing tumors occurring in the context of hereditary tumor syndromes, with known germline mutations, and as sporadic tumors. The pathogenesis of sporadic PCC and sPGL is poorly understood, and little is known about intra-tumoral heterogeneity with respect to molecular aberrations. Since knowledge ...

Physiol. 2 18(4) : 995-998. 1970.-The adrenal catecholamine content of guinea pigs and rats exposed to 7.5 y0 oxygen in nitrogen for periods of 4, 8, and 12 hr decreased significantly ( -40% after 12 hr). With more prolonged exposure, adrenal catecholamine content inc...
متن کاملAdrenal and extra-adrenal myelolipomas - a comparative case report.
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...
متن کاملCytokeratin expression in adrenal phaeochromocytomas and extra-adrenal paragangliomas.
AIM To examine whether adrenal phaeochromocytomas and extra-adrenal paragangliomas are immunoreactive for commercially available and routinely used cytokeratin antibodies. METHODS 18 extra-adrenal paragangliomas and seven adrenal phaeochromocytomas were stained with CAM 5.2, AE1/3, and 34 beta E12 following microwave antigen retrieval of formalin fixed tissue. RESULTS A single case from the...
