A pigmented calcifying cystic odontogenic tumor associated with odontoma: A case report
Abstract
Introdution: Pigmented intraosseous odontogenic lesions are rare, with only 47 reported cases inthe English literature. Among them, pigmented calcifying cystic odontogenic tumor, formerly knownas calcifying odontogenic cyst, is the most common lesion with 20 reported cases.Case Report: The patient was a 19-year-old man. He had a bony, tender expansion in anteriorright maxillary region extended to orbital rim with visual complaints and unilateral headache.Considering radiographic appearance, microscopic study, special and immunohistochemicalstaining, a diagnosis of pigmented calcifiying cystic odontogenic tumor associated with odontomawas rendered.Conclusion: Due to the same neural crest origin for melanocytes and dental lamina, the presenceof melanocytes and melanin in this lesion is accountable. However, till now, no biologic behavioraland prognostic role has been considered for it. This case will add to rare reported cases ofpigmented odontogenic lesions.Key words: Pigmented calcifying cystic odontogenic tumor, Odontoma, Melanocyte
