Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms that arise most commonly in the pleura but have been increasingly reported in extrapleural sites. The authors report the case of an SFT of the scalp that manifested as an enlarging scalp mass in a 2-year-old boy. The mass was surgically excised. Histological examination showed it to be composed of fusiform cells of variable cellularity with a central hyalinization zone. Immunohistochemical staining was positive for CD34 and negative for smooth muscle actin, S100 protein, desmin, and h-caldesmon. On 1-year follow-up, there was no recurrence of the mass. This case presented some diagnostic difficulty because of the wide range of possible diagnoses for a pediatric scalp mass; however, the distinct immunohistochemical profile helped to eliminate other more frequent fibrous tumors of the scalp. The behavior of scalp SFTs is usually benign, but their course can be unpredictable, and recognition of these lesions is essential.

ABSTRACT: Fibroblastic and myofibroblastic tumors of the head and neck are a heterogeneous group of disorders characterized by the proliferation of fibroblasts, myofibroblasts, or both. These tumors may be further subclassified on the basis of their behavior as benign, intermediate with malignant potential, or malignant. There are different types of fibroblastic and myofibroblastic tumors that can involve the head and neck including desmoid-type fibromatosis, solitary fibrous tumor, myofibroma/myofibromatosis, nodular fasciitis, nasopharyngeal angiofibroma, fibrosarcoma, dermatofibrosarcoma protuberans, fibromatosis coli, inflammatory myofibroblastic tumor, ossifying fibroma, fibrous histiocytoma, nodular fasciitis, fibromyxoma, hyaline fibromatosis and fibrous hamartoma. Although the imaging characteristics of fibroblastic and myofibroblastic tumors of the head and neck are nonspecific, imaging plays a pivotal role in the noninvasive diagnosis and characterization of these tumors, providing information about the constitution of tumors, their extension and invasion of adjacent structures. Correlation with the clinical history may help limit the differential diagnosis and radiologists should be familiar with the imaging appearance of these tumors to reach an accurate diagnosis.European Journal of Radiology 11/2014; 84(2).
