Case Report
fiogf49gjkf0d A female fetus, stillborn at 27 weeks’ gestation, who presented a generalized subcutaneous edema without other malformations.
MACROSCOPIC FINDINGS
In the macroscopic exam we found in the thoracic cavity a pleural effusion and a big growing expansive mediastinal neoplasm that measured 8 cm and weighted 56 g. The cut surface showed fleshy appearance and some cystic areas.
The lungs were small, weighted 10 g but had a correct lobulation.

DIAGNOSIS
fiogf49gjkf0d ANTERIOR MEDIASTINAL IMMATURE TERATOMA

Pathology
fiogf49gjkf0d MICROSCOPIC FINDINGS
The mediastinal neoplasm was composed of immature and mature tissues representing each of the three layers derived from the embryonic disk. We found dermal structures and neural, gastrointestinal, bronchial, muscular and fatty tissues with some cystic lesions. We observed some immature neuroectodermic areas with neuroepithelial cells forming tubules and rosettes. Surrounding the neoplasm atrophic thymic rests could be found.
DIAGNOSIS:
1. HYDROPS FETALIS.
2. ANTERIOR MEDIASTINAL IMMATURE TERATOMA
3. BILATERAL PULMONARY HYPOPLASIA CAUSED BY INTRATHORACIC COMPRESSION
