XXXX with a prominent spindle-cell component, a source of diagnostic confusion. A report of 14 cases.

@entity1 @entity43 @entity5 @entity189 @entity2483 @entity4348
Fourteen @entity4348 of the ovary with a prominent component of spindle-shaped epithelial cells are reported. Eleven were initially misdiagnosed as sexcord @entity5 , malignant mesodermal mixed @entity5 , @entity5 of probable wolffian origin, or metastatic @entity189 . All of the @entity5 , however, had one or more features establishing them as @entity4348 , including (a) glands typical of @entity4348 , (b) foci of squamous differentiation, and (c) an @entity2483 . Six cases were examined immunohistochemically, and the epithelial nature of the spindle cells was supported by immunostaining for keratin and epithelial membrane antigen. The @entity1 ranged in age from 42 to 89 years (mean, 61). Four cases were stage I, five stage II, and three stage III. Follow-up information was available in seven cases. Five @entity1 were free of disease at 8, 11, 32, 56, and 103 months, and two @entity1 were alive with disease at 10 and 20 months. The age of the @entity1 , clinical presentation, @entity5 stage, and gross appearance were similar to those of typical @entity4348 . It is important that this @entity5 be distinguished from other @entity43 with a spindle-cell component because of differences in treatment and prognosis.
