Atypical Thymic Carcinoid Presenting as a Mediastinal Mass: A Case Report

Thymic neuroendocrine tumors are extremely rare and have generally been reported in the literature as individual case reports. Unlike their counterparts in other organs, thymic atypical carcinoid tumors usually exhibit aggressive behavior. Complete surgical resection is the recommended treatment. Herein, we present the case of a 70-year-old male patient who underwent surgery with a preliminary diagnosis of thymoma due to an anterior mediastinal mass and whose pathology was reported as a thymic atypical carcinoid tumor.
