Аннотация
INTRODUCTION: Composite pheochromocytoma is a rare tumor of the adrenal medulla composed of pheochromocytoma and neuroblastic tumor. We report the case of a composite pheochromocytoma detected in a patient with neurofibromatosis type 1.
CASE REPORT: A 61-year-old male patient presented occasional sweats with palpitation and moderate high blood pressure. Urinary catecholamine level was increased. CT scan showed a heterogeneous tumor limited to the adrenal gland. Histologically, the tumor showed two components: pheochromocytoma and ganglioneuroma and was diagnosed as a composite pheochromocytoma. This tumor is particularly associated with neurofibromatosis type 1, the NF1 germline gene mutation may be involved in its physiopathology.
CONCLUSION: Composite pheochromocytoma is a rare tumor whose pheochromocytoma component is suspected clinically but the final diagnosis is assessed by pathological examination. Prognosis is still difficult to establish due to the rarity of these tumors.
