Epithelioid osteoblastoma of maxilla: A rare and aggressive variant of a benign neoplasm at an uncommon site
Osteoblastoma (OB) is an uncommon benign bone-forming tumor accounting for <1% of all bone neoplasms. Unlike conventional OB, its small subset variant “Epithelioid osteoblastoma (EO)” is characterized by its propensity for local invasion and recurrent behavior. This rare variant of an uncommon tu...

description | Osteoblastoma (OB) is an uncommon benign bone-forming tumor accounting for <1% of all bone neoplasms. Unlike conventional OB, its small subset variant “Epithelioid osteoblastoma (EO)” is characterized by its propensity for local invasion and recurrent behavior. This rare variant of an uncommon tumor when occurs in an atypical site can lead to diagnostic problems more so due to ambiguous clinico-radiologic presentation. This was what faced in the present case of 18-year-old female with a swelling in upper jaw. OB is usually more common in males and involves primarily the posterior element of the spine and the sacrum (40–55%). Less frequently, long bones of limbs are involved. Clinical, radiological and histopathological correlation in this case guided us to reach at right diagnosis of EO which helped the patient in getting correct treatment which involves surgical excision over conventional curettage. The purpose behind this case presentation is to improve the awareness about this recurrent tumor variant which has many close differentials including well-differentiated osteoblastic osteosarcoma. |
