Pleomorphic liposarcoma of the pterygomandibular space involving the maxilla.
Liposarcoma of the head and neck is rare. Because of its rarity, we report this case of pleomorphic liposarcoma of the left pterygomandibular space, involving the maxilla, maxillary sinus, left lateral maxillary wall, left maxillary gingiva with extension into the buccal space, retro-orbital region, left mandibular ramus, and left zygomatic process. To our knowledge, there are only two other reported cases of liposarcoma involving the maxilla, one of which was a pleomorphic liposarcoma. The pertinent literature is reviewed with an emphasis on the importance of histopathologic classification.
