We identified 4 well-described UCa variants, including those with rhabdoid (9 of 28; 32%; Figure 2, B), poorly differentiated squamous (8 of 28; 29%; Figure 2, C), chordoid
(3 of 28; 11%; Figure 2, D), and lymphoepithelioma-like (1 of 28; 4%) features.
meningiomas often contain regions that are histologically similar to chordoma, with cords or trabeculae of eosinophilic, vacuolated cells in a background of abundant mucoid matrix background.

pattern and small chondroid foci.

Rare pathological types, such as rhabdoid, osteoblastic and chordoid
types have been described (2,24,53).
The enigmatic cycliophoran chordoid
larva has one pair of FMRFamidergic and two pairs of serotonergic nerves (Wanninger, 2005; Fig.
Yet another type of larva, a chordoid
, emerges from the eggs, swims to another lobster, and dies, leaving a few bud cells that develop into a feeding-stage larva.

Finally, D2-40 staining has proved to be effective in distinguishing true chordoid
tumors from chondrosarcoma, but is not currently used.
No other variants (clear cell, chordoid
, or papillary) were identified in the high-grade meningiomas.
