Tek Merkez Deneyimi: Feokromasitoma Olgularının Retrospektif Değerlendirilmesi.

Aim: Pheochromocytomas are neuroendocrine tumors originating from chromaffin cells. The aim of the current study is to review the clinical, laboratory, and imaging findings of pheochromocytoma. Material and Method: Clinical, laboratory, and radiological data of a total of 19 patients diagnosed with pheochromocytoma between 2009-2019 were evaluated retrospectively. Results: Of the 19 patients diagnosed with pheochromocytoma, 13 were female, and 6 were male, and the mean age of 44.1±11.3 years. Hypertension was present in 18 patients, of which 8 were newly diagnosed. It was found that thyroid pathologies were most common after hypertension in patients with pheochromocytoma. The most common symptom after high blood pressure was sweating and headache. All patients had vitamin D deficiency or insufficiency. In 94.1% of patients, the level of normetanephrine observed was found to be elevated. 11 were right-sided, 5 were left-sided, and the remaining 3 were bilateral. The lesion size was less than 4 cm in 36.8%, between 4-6 cm in 42.1%, and greater than 6 cm in 21.1%. Conclusion: In the current study showed that pheochromocytoma has a nonspecific and variable clinic feature. In patients with suspected pheochromocytoma, 24-hour urine normetanephrine and metanephrine levels should be requested as a screening test, especially during attacks, and surgical treatment should be performed after the mass is localized with imaging methods.
