Abstract
In last few years, we have experienced about 50 cases of mediastinal tumor in this clinic.
Nearly 30% of these mediastinal tumor belongs to teratoid, histologically.
The classification of teratoid seems to be very complicated according to their embriological picture. One of the rarest teratoid in the chest, intra-pulmonary teratoma, which we were unable to find a single case in literature in this country.
Recently, however, we came cross to a case who developed egg size mediastinal teratoma in the left upper mediastinum. One of the most striking picture was that, there was an existance of the fibrotic tissue band from mediastinal teratoma into deep inside the lingular where another tumor existed.
The tumor in the lingular was found to be a teratoid by pathlogist. We have named this teratoma in the lung which were connected with mediastinal teratoma “Atypical intra-pulmonary teratoma”.
