Abstract
Composite pheochromocytoma (CP) is a rare adrenal tumor, composed of ordinary pheochromocytoma and neuroblastic components. There is a paucity of information in the literature regarding this entity. We report the case of a 56-year-old woman with a CP of the left adrenal gland with a ganglioneuroma component. A review of the published literature found 110 cases of CP. The median age was 51.5 (5.86) years, and 59/110 (53.6%) were female. Association with genetic predisposition syndromes was found in 22/110 (20%), the most common of which was neurofibromatosis type 1, in 15/110 (13.6%). The most common histologic type of the neuroblastic component was ganglioneuroma in 83/110 (75.5%). Twenty-seven cases reported SDHB immunohistochemistry results; none of which was positive. Nine patients (8.2%) presented/developed metastatic disease, and 9 patients (8.2%) died from disease. To our knowledge, this is the largest review describing clinical, histopathological, molecular, and prognostic features of CP.
