A giant intrapulmonary malignant teratoma - a rare case presentation

Abstract

Germ cell tumors such as teratomas are unusual and most commonly occur in the gonads. Extra-gonadal teratomas are rare, and the thorax, especially the mediastinum, is the commonly involved extra-gonadal site. Teratoma of the intrapulmonary region is rare and often involves the left upper lobe of the lung. In this report, we describe a case of a 20-year-old male diagnosed with an intrapulmonary malignant teratoma arising from the left lower lobe. Teratomas emerging from the lungs present with vague symptoms like breathing difficulty, cough, and hemoptysis. We report this rare appearance of malignant intrapulmonary teratoma that originated from the left lower zone of the lung.
