XXXX : synchronous and metachronous occurrence with @entity5 other than @entity409 .

@entity1 @entity981 @entity96 @entity5 @entity409 @entity2875 @entity99
@entity409 (UELS) is a rare @entity5 that typically occurs in @entity1 . The association of UELS with @entity5 other than @entity409 is exceedingly rare. The aim of the study was to report 3 cases of UELS, 2 of them being interesting because of their association with another @entity5 , vaginal @entity2875 in a teenage @entity1 and @entity981 in a middle-aged @entity1 . Besides, one of our cases of UELS, in a 58-year-old @entity1 , is an extremely rare presentation of such a @entity5 in a middle-aged adult. The @entity1 's clinical features, therapy, and pathologic results were reviewed; immunohistochemical analysis and, in 2 cases, electron microscopy were performed. In this study, all 3 @entity1 were females aged 13, 13, and 58 years. Histopathologic evaluation of resected @entity96 confirmed the diagnosis of UELS in all of them. In 2 of the cases, metachronous occurrence of UELS with vaginal @entity2875 in a teenage @entity1 and @entity981 in a middle-aged @entity1 is described. Careful clinical analysis, histologic studies, and immunohistochemistry are mandatory to distinguish UELS from other @entity99 with similar or overlapping features and to exclude the possibility of other @entity5 that may be considered in the differential diagnosis. The association of UELS with another @entity5 is exceedingly rare.
