title: Plexiform fibrohistiocytic tumor in three children.
abstract: Plexiform fibrohistiocytic tumor is a very rare fibrohistiocytic tumor of intermediate malignancy. It can occur at any age but is more prevalent in children and in young adults. Here we present the clinicopathologic findings of three girls with this tumor. The patients were 8 months, 14 months, and 7 years of age. They each presented with a solitary, nontender, subcutaneous nodule or plaque. Light microscopy and immunohistochemical study findings were compatible with plexiform fibrohistiocytic tumor. We also review the previously published cases in the English-language literature.
