Expansile radiolucent lesion of the Temporomandibular Joint—A diagnostic enigma

Expansile Lesion of the Petrous Apex

Radiolucent lesion of the anterior mandible.

CLINICAL PRESENTATION A 22-year-old white female presented with a solitary, well circumscribed, round radiolucency 15 mm in diameter, with a largely sclerotic border in the mandibular midline, seen on Panorex (Fig 1) and occlusal films.

Mandibular destructive radiolucent lesion: The first sign of multiple myeloma

The occurrence of a mandibular lesion as the first sign of multiple myeloma (MM) is uncommon. This report describes a case of MM diagnosed because of a mandibular lesion. A 62-year-old woman presented a destructive radiolucent lesion in the right mandibular ramus. The lesion caused rupture of the anterior cortical bone and extended from the retromolar area to the coronoid process. An incisional...

Palatal Swelling: A Diagnostic Enigma

Giant cell tumor (GCT) of bone is a giant-cell-rich bony lesion associated with abundant multinucleated osteoclast-type giant cells. It is a primary neoplasm of bone with characteristic clinical, radiological, and pathological features. It is an expansive and lytic lesion without periosteal reaction and prominent peripheral sclerosis. Giant cells are also seen in other diseases like giant cell ...

The hypereosinophilic syndrome--a diagnostic enigma.

The hypereosinophilic syndrome groups together a number of conditions in which eosinophilia occurs for no apparently identifiable cause. Initial reports indicated a uniformly grave prognosis but recent observations suggest a more favourable outcome in certain cases. Two patients with hypereosinophilic syndrome are described whose course of disease and outcome have been completely different.
