OBJECTIVE: To study the clinical and pathological characteristics of @entity2269 . METHODS: Three cases of @entity2269 were evaluated by light microscopy and immunohistochemistry. RESULTS: The @entity1 were all adults, 2 males and 1 female, age range 46 - 62 years (mean 53 years). Clinically, the @entity5 presented as slowly growing painless masses, which were located in the deep soft tissue of the lower extremity, the subcutaneous tissue of the forearm and the ankle respectively. Grossly, they were well-circumscribed @entity5 with a firm consistency. Histologically, the @entity5 were composed of paucicellular spindle or stellate-shaped fibroblastic cells embedded in a densely fibrous or fibromyxoid stroma. The neoplastic fibroblastic cells resembled the reactive fibroblasts by containing fine chromatin and small distinct nucleoli without cellular atypia or mitotic figures. Immunohistochemically, the neoplastic cells showed diffuse and strong immunoreactivity for @entity2277 , focal staining for alpha-SMA, @entity46574 and @entity2283 . CONCLUSION: @entity2269 is a benign fibroblastic @entity5 with distinctive clinical and pathological characteristics. It should be differentiated from a variety of reactive or low-grade fibroblastic lesions.
