Odontogenic myxoma of maxilla: A review discussion with two case reports.

Limdiwala P, Shah J - Contemp Clin Dent (2015 Jan-Mar)

Bottom Line: Most common clinical variant is associated with the impacted tooth and shows local invasion with destruction of adjacent structures and displacement of teeth.Radiographically, common manifestations are multilocular radiolucent areas with well-defined borders and typical soap bubble or tennis racket appearances.This paper presents two rare case reports of OM of maxilla along with review discussion.

ABSTRACT
Odontogenic myxoma (OM) is a rare entity of slowly growing benign neoplasm of ectomesenchymal origin, comprising of 3-6% of all odontogenic tumors that histologically presenting spindle-shaped, stellate and round cells within loosely arranged myxomatous tissue stroma. OM originates from the dental papilla, follicle or periodontal ligament with an exclusive location in the tooth-bearing areas of the jaws, association with missing or unerupted teeth. Clinically and radiographically the reported incidence and demographic information of this tumor has wide variability. Most common clinical variant is associated with the impacted tooth and shows local invasion with destruction of adjacent structures and displacement of teeth. Radiographically, common manifestations are multilocular radiolucent areas with well-defined borders and typical soap bubble or tennis racket appearances. This paper presents two rare case reports of OM of maxilla along with review discussion.

Figure 3: Gross specimen of excised soft tissue mass of case 1

Mentions: The patient underwent radiographic investigations that suggested radiolucent area around 3 cm × 2 cm in size at interdental and periapical area of 22 and 23 region. A thin sclerotic bone reaction was seen at only superior border, rest of the area was blending to adjacent bone. Internal structure showed hazy radiolucency with one to two thin septa crossing lesion centrally. Mesial displacement of 22 was seen without any root resorption [Figure 2]. Clinico-radiographic features and history of recurrence was suggestive of either odontogenic keratocyst or lateral periodontal cyst. A routine hematological investigation was done before surgery. As negative aspiration was found, lesion was totally excised and specimen sent to the pathology department [Figure 3]. Histologically, section showed abundance of fusiform, stellate and round cells in myxoid tissue [Figure 4] and was diagnosed as myxoma.
