Surgical treatment of micronodular thymoma with lymphoid stroma

Abstract

Abstract This case was about a 71‐year‐old man presented to our clinic for an anterior mediastinal mass found on routine chest computed tomography (CT). CT scan showed a lobulating contoured mass in the anterior mediastinum. A preliminary diagnosis was thymoma. The patient underwent subxiphoid uniportal video‐assisted thoracoscopic surgery for the extended thymectomy and complete excision of the tumour. The pathological examination showed a micronodular thymoma with lymphoid stroma (MTWLS). In conclusion, this report described an extremely rare tumour, MTWLS, and MTWLS might be considered in the differential diagnosis of mediastinal tumour, especially thymoma.
