Two cases of intrapulmonary teratoma

We encountered two unusual cases of intrapulmonary teratoma, one in a 31-year-old female and the other in a 15-year-old female. The chief complaint of both patients was fever, and in both a consolidation was detected in the left upper lobe using routine radiography. We performed left upper lobectomy for the former patient and segmentectomy of the left lingual segment for the latter. Neither tumor communicated with the mediastinum. Histological examination revealed a pulmonary teratoma containing no thymic tissue in both. Intrapulmonary teratoma has been reported to be extremely rare, and only 27 cases including these two have been reported in the literature.
