A multilocular thymic cyst associated with mediastinal seminoma: evidence for its medullary epithelial origin highlighted by POU2F3-positive thymic tuft cells and concomitant myoid cell proliferation

Mediastinal seminoma associated with multilocular thymic cyst

An asymptomatic 26-year-old man received an annual medical check-up, and chest X-ray showed a protrusion of the aortopulmonary window. Chest computed tomography (CT) revealed an anterior mediastinal tumor and cysts with thin wall and septum enhancement. The preoperative diagnosis was cystic thymoma or malignant lymphoma. We performed total resection of the tumor through a median sternotomy. The...

Multilocular Thymic Cyst Associated with Mediastinal Teratoma: A Case Report

Congenital cysts are typically unilocular and thin-walled to the point of translucency; careful histopathologic examination shows no evidence of inflammation. In contrast, acquired thymic cysts are usually multilocular, hence the commonly used term “multilocular thymic cyst (MTC).” These cysts have thick, fibrous walls, and histopathologic examination typically reveals significant inflammation ...

Calcified multilocular thymic cyst associated with thymoma: a case report

INTRODUCTION There are few case reports of thymoma with a thymic cyst. Such an association renders it difficult for any pathologist to differentiate from other neoplasms, such as a cystic thymoma. CASE PRESENTATION A 50-year-old Berber woman from Morocco was admitted with a chronic cough of more than 10 years duration. Her medical history and physical examination were normal. Anterior chest r...

Mediastinal Thymic Cyst: A Rare Case Report

Mediastinal thymic cyst after open heart surgery.

A benign thymic cyst seen six years after valvular heart surgery is described, and the question of the possible role of previous surgical trauma in the development of the cyst is raised.
