A case of spindle cell lipoma of the tongue

Abstract

We reported a rare case of spindle cell lipoma of the tongue. A 56-year-old man was referred to 11 months since the operation.

Spindle Cell Lipoma of the Tongue: A Clinicopathologic Study of 8 Cases and Review of the Literature

“…Spindle cell lipomas are infrequently encountered in the oral region, with lingual examples of this entity in particular being distinctly rare. To our knowledge, only 24 cases of spindle cell lipoma involving the tongue have been reported in the English literature [3,5,[9][10][11][12][13][14][15][16][17][18][19][20][21]. The clinical and pathologic features of lingual spindle cell lipoma based on findings from the present series combined with previously published data are summarized in Table 3.…”

“…Lingual spindle cell lipomas are benign neoplasms managed adequately by local excision. The present series along with prior reports with known follow up information have shown no instances of tumor recurrence or aggressive biologic behavior [3,11,14,16,18,19,21]. On gross examination, spindle cell lipomas are well circumscribed neoplasms with a firmer consistency than ordinary lipomas.…”

“…While most ordinary lipomas of the oral cavity involve the buccal mucosa, tongue or lip [1][2][3][4][5][6][7][8], lingual examples of spindle cell lipoma remain rare. The reported literature pertaining to spindle cell lipoma of the tongue is relatively sparse and comprised predominantly of single case reports and limited descriptions of small numbers of cases among larger series of lipomas of the oral cavity [3,5,[9][10][11][12][13][14][15][16][17][18][19][20][21]. In this study, we analyzed eight new cases of lingual spindle cell lipoma in order to further characterize the clinicopathologic features of this uncommon type of intraoral lipomatous tumor.…”

Spindle cell/pleomorphic lipoma of the cheek: A case report

“…The primary treatment for SL/PL is surgery, and reoccurrence is considered rare. In Japan, Yamada et al reported on removing part of the fascia due to reported observations of adhesion of some tumors to the fascia of the masseter muscle, but in other reports all borders were clear and separation was simple, so the tumors were removed without establishing a safety margin . In this case, the borders were clear and separation was easily performed.…”

“…According to pathology and histology, SL/PL is composed of myxofibrous stroma and mature fat components, mixed adipocytes and spindle cells, with rope-shaped collagen fibers in the stroma. [6][7][8][9][10][11][12][13] This disease is clinically difficult to diagnose, and because of the diverse appearance of the tissue, attributable to structural component ratios, there are delays in distinguishing it from highly specialized types of liposarcoma. [14][15][16] For SL/PLs present in atypical locations, there are reports of wide-ranging ablation after being regarded as a highly specialized liposarcoma.…”
