A rare case of mediastinal nonseminomatous germ cell tumor with acute Megakaryocytic Leukemia

Abstract

The most common extragonadal site of Nonseminomatous Germ Cell Tumours is the mediastinum. These are similar to their gonadal counterparts in histology but have a poorer prognosis. The association of mediastinal germ cell tumours with blood borne malignancies has been established in many case reports. However, the association of concomitant mediastinal non seminomatous germ cell tumours with Acute Megakaryocytic Leukemia is very rare with only 26 cases reported in the last 07 Decades. These patients have a very poor prognosis with only one survivor being reported till present date. AML (M7), a rare variant of Primary AML , has been more commonly associated with non seminomatous germ cell tumours. Here, we report such a rare case of dual malignancy, Non Seminomatous Germ Cell Tumour with AML (M7) which was managed at our centre.
