Primary Central Mec Case Studies

Primary central MEC has been reported in the first to seventh decade; however, cases occurring in the: fourth and fifth decades are most widespread. [6] In children, gender ratio and the mandible to maxilla ratio is 1:1, whereas in adults: MEC is slightly more common in women and the posterior mandible. [6] In this case the lesion was seen in 16 yr female patient.

The pathogenesis of intraosseous MEC is much debated. It may originate from, [7]
• Entrapment of retromolar mucus glands within the mandible which undergo neoplastic transformation
• Neoplastic transformation of mucus secreting cells found in the pleuripotent epithelial lining of dentigerous cysts associated with impacted third molars.
• Developmentally induced embryonic remnants of the submaxillary gland within the mandible.
• Neoplastic transformation and invasion from the lining of maxillary sinus …show more content…
Radiographic examination is important to know the diagnosis and to know the extent of the lesion particulary in case of maxillary lesions. The radiologic features are usually a well-circumscribed uni-or multilocular radiolucency with the periphery of the lesion is mostly well-defined, corticated and often crenated or undulating in nature, which is similar to a benign odontogenic lesion. [8] The multilocular lesion has an internal structure that resembles a soap bubble or honeycomb as in our
