Rare case of bizarre parosteal osteochondromatous proliferation presenting in the zygoma.
Bizarre parosteal osteochondromatous proliferation is a rare benign lesion that tends to occur within the bones of the hands and feet. To our knowledge this is the third published case of its occurrence in the head region. We report the case of a 31-year-old man with an eight-month history of an asymptomatic, slowly enlarging lump on the right zygomatic area diagnosed as bizarre parosteal osteochondromatous proliferation. Diagnosis depends on specific radiological and histopathological features. Treatment is by complete excision, and recurrence has been reported in up to 50% of cases. Awareness of the condition will expedite its correct diagnosis and management.
