Ameloblastoma is a slow-growing locally aggressive, benign
odontogenic epithelium with a greater tendency for recurrence and involves
aggressive bone loss and teeth. It is believed to be derived from cell rests of
the enamel organ, either remnants of the dental lamina or Hertwig's sheath, the
epithelial rest of Malassez. An Unicystic Ameloblastoma (UA) represents an
ameloblastoma variant, that's a cyst. They are often related to an unerupted
third molar, with a peak incidence within the third and fourth decade of life.
The most common site of preference is the mandibular molar
and ramus area than the anterior and premolar region. The article presents two
case series of unicystic ameloblastoma of a 25-year-old female who had a
localized swelling in the left side of the mandible which resembled a
keratocystic odontogenic tumor clinically and radiographically. Based on
histopathological examination the final diagnosis was unicystic ameloblastoma
with the mural pattern. The second case report presented a 32-year-old female
with a diffuse swelling in the left lower jaw which histopathologically
revealed ameloblastoma with the plexiform variant. An incisional biopsy was
done to get a definitive diagnosis for both cases. A postoperative panoramic
radiograph was taken and was found to be satisfactory in both cases. The case
series presented certain unique features of female predilection and a
multilocular variant with mural and plexiform pattern unicystic ameloblastoma.
Both patients were surgically managed more conservatively with enucleation and
cauterization as cystic types are found to be less aggressive compared to solid
variants of ameloblastoma. They were on a regular follow period
postoperatively. It can be concluded that unicystic ameloblastoma with a mural growth
pattern has a tendency for recurrence if inadequately managed surgically.
Proper management avoids the propensity of recurrence rate.
