A case of liposarcoma in the face.

Liposarcoma in the face region is extremely rare. We reported a case of recurrent liposarcoma of the right cheek of a 54-year-old man. He received first tumor excision in another hospital in May, 1994. In the histologic examination, the tumor mass consisit of lipoblast, uniformly shaped, small round microvacuolated cells containing atypical hyperchromatic vesicular nuclei were present from lower dermis to subctaneous tissue. The histopathologic classification was round cell type. Partially, transitions toward the myxoid type and screlosing type were present. One year later, local recurrence occured, but there was no metastasis. Second wide local excision was performed in June, 1995. Few changes occured in the histological findings of the second excision and it revealed round cell type.
