Abstract
Pheochromocytomas are rare catecholamine-secreting tumors arising from the adrenal medulla, often presenting with episodic hypertension, palpitations, and diaphoresis. Meanwhile, undifferentiated carcinoma of the uterine corpus is an aggressive and poorly differentiated endometrial malignancy with a high propensity for metastasis and poor prognosis. The incidental detection of such an aggressive malignancy in a patient undergoing evaluation for pheochromocytoma is exceedingly rare and poses significant diagnostic and therapeutic challenges. Here, we present a case of a 63-year-old woman who was being evaluated for right pheochromocytoma and underwent 131 I-MIBG scan for the same, which led to incidental detection of synchronous uterine carcinoma.
