OBJECTIVE: To study the clinicopathologic features and differential diagnosis of @entity13904 ( @entity13904 ). METHODS: The clinical, radiologic and pathologic features of three cases of @entity13904 were analyzed. RESULTS: All the 3 cases occurred in male adults. The age ranged from 44 to 53 years. The presentations included left neck mass, @entity158 and bilateral shoulder masses. Histologically, @entity13904 was composed of a mixture of spindle and epithelioid @entity5 cells. Transition between the two cell types was demonstrated. The @entity5 cells were arranged in compact sheets, vague nodules or intersecting fascicles, amongst a collagenous stroma. Central @entity39 was identified in one case, reminiscent the morphology that seen in @entity242 . There was no evidence of angiogenesis, though focal presence of intracytoplasmic vacuoles was seen in one case, as in classic examples of @entity13904 . Immunohistochemical study showed that the @entity5 cells expressed both epithelial ( @entity1325 / @entity1326 , CAM5.2 and epithelial membrane antigen) and endothelial ( @entity2279 , @entity21468 ) markers. Two of the cases were also positive for @entity2280 . All of the @entity1 were treated by surgical resection. Two @entity1 remain well at 14-month and 9-month follow up, respectively. The remaining @entity1 had repeated local recurrences during a 6-year period. CONCLUSIONS: @entity13904 represents a rare morphologic type of @entity8146 . It has some overlapping histologic features with @entity242 and @entity13904 . The endothelial nature of @entity13904 is difficult to be verified on the basis of morphologic examination alone. Confirmation of the diagnosis with immunohistochemistry is necessary. @entity13904 is likely related to @entity13904 and may represent a cellular spindle cell variant of @entity13904 .
