Objective: Clinically, the odontogenic keratocyst(OKC)is usually manifested by an asymptomatic growth.It appears as a welldefined uni-locular or multilocular lesion in mandible.The most common location is the posterior region, the angle or the ramus.
OKCs have a tendency to grow predominantly mesiodistally along the length of the bone because of their propensity to spread
along the intramedullary space “growing in the length of the bone” therefore lesions cause minimal buccolingual expansion. In
this case report , a clinically severe OKC in buccolingual direction is presented.
Case Report: A 57-year old man attended to our clinic with a complaint of severe swelling in the left side of the mandible for
2 months clearly seen at extraoral examination. Intraoral examination revealed displacement of the teeth (incisor,canine and
premolar ) adjacent to the lesion and a hard swelling. Orthopantomogram showed a unilocular radiolusent lesion with clear
contours with in the mandibular anterior region extending transversely from mandibular mesial root of left first molar to right
canine. CBCT scan revealed a severe buccolingual expansion (30 mm).Ameloblastoma was the initial diagnosis .Biopsy was
performed and the material was sent for histopathological examination. The definite diagnosis was odontogenic keratocyst.
Conclusion: Radiographically,OKCs demonstrate minimal expansion.Most frequently axial sections of CBCT scans showed
that OKCs tend to grow in an mediolaterally direction within the bone.However, in rare cases these lesions might show a severe
expansion in buccolingual direction.
