Orthokeratinizing odontogenic cyst of maxilla with complex odontoma.

Kulkarni M, Kheur S, Agrawal T, Ingle Y - J Oral Maxillofac Pathol (2013)

Bottom Line: We came across a case of a 26-year-old male with swelling on his face along with difficulty in breathing.However, there is no report in the English literature of the simultaneous occurrence of these two lesions and hence this case is very rare.It is unclear whether the two lesions were just coincidental or were actually related to each other.

ABSTRACT
The orthokeratinized odontogenic cyst (OOC) and odontoma are the odontogenic cyst and tumor respectively that are minimally invasive neoplasms of head and neck region. OOC is a rare variant of odontogenic cyst characterized by the presence of excessive orthokeratin covering the cystic lining. Odontoma is a benign neoplasm/hamartoma often discovered accidently on panoramic radiographs. We came across a case of a 26-year-old male with swelling on his face along with difficulty in breathing. On the basis of radiographic and histopathological findings the final diagnosis of OOC associated with odontoma was given. However, there is no report in the English literature of the simultaneous occurrence of these two lesions and hence this case is very rare. It is unclear whether the two lesions were just coincidental or were actually related to each other.

The photomicrograph shows cystic lumen lined by a continuous layer of orthokeratinized stratified squamous epithelium of 6-8 layer thickness with the absence of rete ridges. The lumen is extensively filled with orthokeratin (H&E stain, ×100)

Figure 3: The photomicrograph shows cystic lumen lined by a continuous layer of orthokeratinized stratified squamous epithelium of 6-8 layer thickness with the absence of rete ridges. The lumen is extensively filled with orthokeratin (H&E stain, ×100)

Mentions: The histopathological examination revealed the cystic space which was lined by a continuous layer of stratified epithelium of 6-8 cell layer thickness with prominent basal cell layer and the absence of rete ridges. The stratified epithelium was orthokeratinized in nature with prominent stratum granulosum layer. Abundance of orthokeratin was present in the cystic lumen. The connective tissue showed minimal or no inflammatory response. One portion of the lesion was hard and solid which was processed by decalcification. The decalcified section showed presence of dentine and pulp like tissue arranged in an irregular pattern. Enamel spaces were seen in some areas. On the basis of thorough histopathological examination, the final diagnosis of orthokeratinizing odontogenic cyst associated with complex odontoma was given [Figures 3 and 4].
