A Case of Parotid Spindle Cell Lipoma

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.…”

[5][6][7][8][9][10][11][12][13]23 In this case, the borders were clear and separation was easily performed. Considering that good results were achieved in previous cases, we excised the tumor without establishing safety margins.…”
