Atypical lipomatous tumor/Well differentiated liposarcoma (ALT/WDLS) is a rare tumor of the tongue. ALT/WDLS is the most common subtype of liposarcoma arising usually in the retroperitoneum and thighs of middle-aged adults. Although recurrence of ALT/WDLS is thought to be unlikely after complete excision, close long-term follow-up is necessary due to its malignant potential when dedifferentiating. We present a very rare case of bilateral involvement of ALT of the tongue in 79-year-old Asian male presenting occasionally accidental biting and difficulty in mastication.
