Calcifying fibrous tumor of the adrenal gland
Abstract
Calcifying fibrous tumor is an uncommon entity with distinctive pathologic features. Most calcifying fibrous tumors involve the peripheral soft tissues or serosal surfaces, with reports of visceral examples of this lesion being extremely limited. We report the clinical and pathologic features of an unusual case of calcifying fibrous tumor occurring in the adrenal gland of a 32-year-old woman. Microscopically, the lesion was well circumscribed and composed of dense, poorly cellular collagenous tissue, scattered spindle cells, an inflammatory infiltrate consisting of plasma cells and lymphocytes, and dystrophic calcifications. The morphologic diagnosis of calcifying fibrous tumor was supported by diffuse positive immunoreactivity for factor XIIIa and absence of reactivity for muscle specific actin, smooth muscle actin, and anaplastic lymphoma kinase. Although rare, awareness that calcifying fibrous tumor may occur at this particular site is important so as not to confuse this lesion with other mesenchymal neoplasms of the adrenal gland. © 2007 Elsevier Inc.
