Peripheral odontogenic myxoma of maxillary gingiva: A rare clinical entity
A 41-year-old female patient was referred to our department with history of a slowly enlarging gingival mass in the anterior maxilla of 6 months duration. There was no associated history of trauma, pain, or tooth extraction. Intraoral examination revealed a solitary, non-tender swelling on the labial gingiva of the left maxilla in relation to 21 and 22, measuring about 1 × 2 cm []. The lesion was firm in consistency and the mucosa covering the lesion was normal in color; no mobility of the regional teeth was seen. The rest of the clinical head and neck examination was unremarkable. No radiographic changes were seen associated with the lesion []. Based on the overall findings, provisional diagnosis of fibroma was made.\nThe lesion was surgically excised under local anesthesia and subjected to histological examination. Microscopic examination of Hematoxylin and Eosin stained section demonstrated atrophic, parakeratinized stratified squamous surface epithelium []. Underlying stroma showed abundant loose myxoid tissue containing few collagen fibrils. The tumor was composed of loosely arranged spindle- and stellate-shaped fibroblasts with small round nuclei suspended in a delicate network of collagen fibrils [Figures and ]. Small blood vessels were also present and no noticeable odontogenic islands were seen. A diagnosis of peripheral OM was made. Six months of follow-up showed no evidence of recurrence.
