INTRAMUSCULAR VARIANT OF LIPOMA IN THE TONGUE: A CASE REPORT

Abstract

Although 20% of lipomas occur in the head and neck, only 1% to 4% of these are in the oral cavity. Histologically, they are classified into simple lipomas, fibrolipomas, angiolipomas, pleomorphic lipomas, spindle cell lipomas, sialolipomas, atypical lipomas, and intramuscular or infiltrative lipomas. The objective of this work is to report a clinical case of intramuscular lipoma in the tongue, since it is an uncommon lesion and requires follow-up because of its greater potential for recurrence. Patient S.P.O.G. is 78 years old with a nodular lesion in the right border of tongue present for 5 years. The lesion had well-defined borders, soft consistency, mucosa-like staining, and absence of painful symptomatology. The treatment was performed as an excisional biopsy. The histopathologic examination reported intramuscular lipoma, presenting muscle fibers inside and at the periphery of the lesion. The patient continues in periodic follow-up.
