Case Report: Diffuse Large B-Cell Lymphoma in the Wall of a Thymic Cyst
Abstract
Thymic cysts are rare lesions (1–5% of all mediastinal masses) and, most of the times, are incidental findings. The coexistence of a lymphoma and a thymic cyst is rare. In the case reported herein, microscopic foci of a diffuse large B-cell lymphoma were identified in the wall of a resected thymic cyst. This case report adds to the current knowledge of this rare entity and highlights the necessity of early surgical resection of mediastinal cysts over watchful waiting.
