Abstract

Organoid (hypermature) teratomas are highly specialized teratomas showing organ formation, most frequently from the digestive tract or bronchial wall.

We present four cases of ovarian organoid teratomas, one with a distinguishable mandible with teeth, one with small intestine, one with large intestine containing a well differentiated neuroendocrine tumor and another with both large intestine and bronchial wall.

These tumors have a distribution similar to conventional teratomas and usually behave benignly, although cases of malignancy have been reported.

Resumen

Los teratomas hipermaduros u organoides son teratomas altamente especializados en los que existe formación de órganos. Los más comunes son del tracto digestivo y de la pared bronquial. Presentamos cuatro casos de teratomas organoides del ovario: uno con formación de mandíbula con estructuras dentales, otro con intestino delgado, otro con intestino grueso con un tumor neuroendocrino bien diferenciado, y otro intestino grueso y pared bronquial. Estos tumores son de comportamiento benigno, aunque se han descrito casos con malignización. Pueden ocurrir en cualquier lugar donde se localicen los teratomas convencionales.
