P. Oliveira et al., MITOCHONDRIA ROUGH ENDOPLASMIC-RETICULUM COMPLEXES IN A MALIGNANT FIBROUS HISTIOCYTOMA, Ultrastructural pathology, 18(4), 1994, pp. 433-436
Mitochondria-rough endoplasmic reticulum complexes identical to the on
es usually found in chordoma were frequently observed in tumors cells
of a malignant fibrous histiocytoma arising in the left thigh of a 48-
year-old woman. Although the significance of these structures is unkno
wn, this finding is consistent with the known transformation of chordo
ma into malignant fibrous histiocytoma.
