Özet
Feokromasitomalar sempatoadrenal sistemin kromafin hücrelerinden köken alan nadir tümörlerdir ve %85’i adrenal medullada lokalize olur. Malign feokromasitomalar tüm feokromasitomaların %10’unu oluşturur. Klinik, biyokimyasal ve histopatolojik yöntemlerin hiçbiri malign tümörleri benign tümörlerden ayıramadığından, malignite uzak metastaz varlığında tanımlanır. Her ne kadar bazı vakalarda metastazlar takip sırasında gelişebilirse de, vakaların büyük çoğunluğunda ilk tanı anında metastatik hastalık mevcuttur. Bu olgu sunumunda, malign feokromasitomalı bir hastada takip sırasında rekürens ve uzak metastazlarının 18-florodeoksiglukoz pozitron emisyon tomografi/ bilgisayarlı tomografi (FDG PET/BT ) ile saptanması sunulmuştur.

Pheochromocytomas are rare tumors arising from chromaffin cells of the sympathoadrenal system and 85% of them are located in the adrenal medulla. Malignant pheochromocytomas account for 10% of all pheochromocytomas. Since clinical, biochemical and histopathological features can not reliably distinguish malignant from benign tumors, malignancy is established in the presence of distant metastases. Although in some cases, metastases may develop during follow-up, most of these tumors have metastatic disease at initial presentation. In this case report, detection of distant metastases and recurrence developed during follow-up with 18-flouro-deoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in a patient with malignant pheochromocytoma was presented.
