Abstract

Mature teratoma is the most common primary germ cell tumor in the mediastinum. On rare occasions, cystic teratomas rupture in adjacent structures, such as pleural space, pericardium, lung or tracheobronchial tree. We present a case of a mediastinal mature cystic teratoma in 16-year-old female with complex rupture into the lung, bronchus and skin. Mature mediastinal teratoma fistulized to the skin has not been previously described.

Highlights

Mature teratoma is the most common primary germ cell tumor in the mediastinum [1]
We report a case of mature mediastinal teratoma (MMT) with complex rupture into the lung, bronchus and skin with cysto-cutaneous fistula, which produced sebum and hair
Mediastinal teratomas are asymptomatic in up to 53% of cases and are frequently discovered incidentally on chest radiography performed for other reasons [2]

Summary

Introduction

Mature teratoma is the most common primary germ cell tumor in the mediastinum [1]. It is composed of ectodermal, mesodermal, and endodermal derivatives. These tumors rarely rupture into the adjacent structures, such as the pleural space, pericardium, lung parenchyma or tracheal tree. We report a case of mature mediastinal teratoma (MMT) with complex rupture into the lung, bronchus and skin with cysto-cutaneous fistula, which produced sebum and hair.
