Epithelioid osteoblastoma or aggressive osteoblastoma of the astragalus. Presentation of a case and revision of clinical and pathological symptoms

Epithelioid osteoblastoma in the periapical region of maxillary molars: a rare case report

Osteoblastoma is a rare benign bone-forming neoplasm which rarely affects the jaws. Due to the rarity and wide range of clinical, radiographic, and histopathological findings, the diagnosis of gnathic osteoblastoma can be challenging. The authors report here an unusual case of osteoblastoma in the periapical region of maxillary molars. An 18-year-old woman presented with pain and swelling of th...

Epithelioid osteoblastoma: A histopathological dilemma between juvenile ossifying fibroma and low-grade osteosarcoma

Swelling of jaws with mixed opacity and lucency can have a spectrum of differential diagnosis, which includes odontogenic tumors, fibro‐osseous lesions and rarely the connective tissue neoplasms. With respect to the fibro‐osseous lesions, most of the time, histopathological features will be overlapping. In such cases, it is very important to arrive at a precise diagnosis for better treatment pl...

Aggressive osteoblastoma.

The clinical, radiological and pathological features of two cases of an osteogenic tumour with long survival are described. The tumours have the histological pattern of benign osteoblastoma with other more cellular and aggressive features suggestive of a low grade osteosarcoma. They are locally invasive but the absence of metastases indicates that separation from both entities is justified clin...

Malignant transformation of osteoblastoma.

A recurrent spinal tumor confidently diagnosed as osteoblastoma eventually terminated as a sclerosing osteoblastic which metastasised nine years after the onset of symptoms.
