Abstract
Solitary fibrous tumors (SFTs) are mesenchymal neoplasms uncommonly occurring in the salivary glands. In rare instances, SFTs can contain mature fat, atrophic fat, or vacuolated cells previously termed ‘pseudo-lipoblasts’, which may be misinterpreted as a feature of malignancy. We report an unusual tumor with pseudo-lipoblasts occurring in the sublingual gland. The tumor exhibited a prominent hemangiopericytic pattern, bland cytology, and immunohistochemical and morphologic features consistent with that of an SFT. A review of 15 cases of SFTs of the salivary glands is presented. Emphasis is laid upon the histologic differential diagnosis and the clinical features of these tumors.
