Abstract
Spindle cell lipoma is a benign lipomatous neoplasm, which rarely occurs in the oral cavity. The aims of this paper are to report a case of spindle cell lipoma located in buccal mucosa and discuss the main clinical, histological, and immunohistochemical findings of this entity. Thus, we report a 4-year history of an asymptomatic smooth surface nodule in an elderly Caucasian man with clinical hypothesis of fibroma. The histopathological examination showed spindle cells, mature adipose tissue, and many mast cells in a stroma of connective tissue presenting ropey collagen fibers bundles. After immunohistochemical analysis, the final diagnosis was spindle cell lipoma.
Highlights
Spindle cell lipoma (SCL) is a histological variant of lipoma that often occurs in the neck, back, and shoulder [1]
We report a case of a spindle cell lipoma located in the buccal mucosa and discuss important features of this rare oral lesion
SCL was first described by Enzinger and Harvey in 1975
Summary
Spindle cell lipoma (SCL) is a histological variant of lipoma that often occurs in the neck, back, and shoulder [1]. It is rare in the oral cavity [2] and only 35 well-documented cases were published between 1984 and 2012 in the oral region [3]. SCL is removed without imaging examination because it is usually found in superficial locations and is small in size [4]. We report a case of a spindle cell lipoma located in the buccal mucosa and discuss important features of this rare oral lesion
