Key Words: Hamartoma • Mediastinal mass
A 42-year-old man was admitted with chest discomfort lasting 4 months. Thorax magnetic resonance imaging showed a round mass in the visceral compartment of the mediastinum (Fig. 1). It was encapsulated and removed easily during exploratory thoracotomy. Pathologic examination revealed hamartoma (Fig. 2). This case showed us that ‘hamartomas’ could be as big as 6 cm, encapsulated and placed extra-pulmonary in the hilus.

Fig. 2. Photomicrograph of the specimen showed ciliated respiratory epithelium (A) possibly implying that it originates from the mediastinal aspect of the lung. Mature hyaline chondral islands beneath the epithelium and calcification around this region can be seen (B); also, bone marrow cells and calcified bone lamellae with lipoid tissue are shown (C) (H&E, x25).
