A Case of Solitary Fibrous Tumor That Developed on the Scalp / 대한피부과학회지

ABSTRACT

Solitary fibrous tumor is an uncommon mesenchymal neoplasm that can arise in both pleura and extrapleural locations. This tumor is composed of spindled cells intimately admixed with collagen bundles that are arranged in a 'patternless pattern'. Immunohistochemically, the tumor cells strongly express CD34 and vimentin. This tumor can mimic a variety of benign and malignant mesenchymal tumors. Rare cases of primary cutaneous solitary fibrous tumor have recently been reported and they have been added to an increasing variety of mesenchymal tumors that may primarily arise in the skin. We present here a case of primary cutaneous solitary fibrous tumor and we briefly review the relevant literature.
