XXXX : a case report and review of the literature.

@entity43 @entity1 @entity249 @entity1420 @entity7 @entity5 @entity2931 @entity406 @entity730 @entity1463 @entity2277
@entity43 is an extremely rare @entity5 occurring predominantly in the second and third decades of life. It presents most often with non-specific symptoms. We describe a new case occurring in a young @entity1 presenting with @entity249 and irregular menses. Ultrasound examination showed a left heterogenous ovarian mass without focal @entity730 . Histological features included a pseudolobular pattern with focal areas of @entity1463 , prominent vascularity and a two-cell population of spindled and polygonal cells. Immunohistochemical analysis for actin, @entity2277 , laminin, @entity7 ( @entity7 ), @entity2931 and @entity1420 receptors using @entity406 -fixed and paraffin-embedded materials showed predominant positivity for a-smooth muscle actin and consistent positivity for laminin and @entity2277 . The epidermal @entity7 demonstrated @entity5 vascularity. @entity2931 and @entity1420 receptors were not expressed. suggesting hormonally independent development. Menstrual cycle disturbances, however, were corrected following extirpation of the @entity5 , indicating some endocrine involvement. In addition, the @entity1 became pregnant ten months after the operation. The differential diagnosis is discussed.
