Endometrioid-like variant of XXXX . A clinicopathological analysis of eight cases.

@entity43 @entity1 @entity5 @entity4 @entity2970 @entity160 @entity490 @entity3 @entity4348
The clinical and pathological features of eight @entity43 with glandular patterns resembling those of @entity4348 are described. The @entity1 ranged in age from 11 to 34 years (mean, 22 years) and presented with @entity490 or @entity4 . The serum @entity160 ( @entity160 ) level was elevated at the time of presentation or later in all seven @entity1 in whom it was measured. Seven @entity5 were unilateral, one was bilateral, and three had spread beyond the ovary. There was a contralateral streak gonad in two cases. The @entity5 were 6-35 cm in diameter; seven were solid and cystic, and one was a unilocular cyst with a small solid nodule in the wall. Microscopic examination revealed a prominent, and in two cases, pure endometrioid-like glandular pattern that often simulated that of an early secretory endometrium. @entity2970 were also present in five @entity5 ; minor teratomatous foci (squamous epithelium and cartilage) were present in one. Immunohistochemical staining revealed @entity160 , alpha-1-anti-trypsin (AAT), and carcinoembryonic antigen within the glandular epithelium; @entity160 and AAT were also present in areas showing the other patterns. Three @entity1 died of recurrent or @entity3 19-60 months postoperatively; in the remaining cases, there was a @entity5 -free follow-up of short duration. The endometrioid-like pattern reflects an unusual form of @entity2970 that should be distinguished from @entity4348 .
