Desmoplastic ameloblastoma (DA) is one of the 6 histopathological subtypes of ameloblastoma. Hybrid lesions in which histopathologically conventional ameloblastoma coexists with areas of DA are rare. A 40-year-old male was referred to our hospital complaining of a swelling in the right premolar region of the mandible. A panoramic radiograph showed an area of radiolucency with a well-defined cor...

Desmoplastic ameloblastoma is a relatively rare subtype of ameloblastoma. Tumor resection with curettage is considered the most reliable treatment for desmoplasticameloblastoma because of its aggressive behavior with bone invasion. A 43-year-old Japanese man presented with a swelling on the left side of his anterior maxilla. A painless, bone-like hard swelling was observed in the anterior maxil...

Collagenous fibromas are rare fibrous soft tissue tumours that usually arise in subcutaneous tissue or skeletal muscle at a variety of anatomical sites. These lesions commonly present as painless, slow-growing mobile masses. We describe a unique case of a 41-year-old woman presenting with a posterior neck swelling and longstanding history of severe ongoing pain in the right scapular region, sho...

BACKGROUND Giant cell fibroma is a type of fibrous tumour of the oral mucosa which rarely affects children under the age of 10. The purpose of this paper was to contribute two clinically and histologically documented cases of giant cell fibroma in the free gingiva of a 7 and 6 year old boys. METHODS Both nodules were presented in the mandibular anterior region. In the differential diagnosis s...

Case Description: This tumour appeared in the anterior region of the left upper jaw of a 24year-old female, between left lateral incisor and canine. The lesion was painless and only a slight swelling of the hard palate mucosa was noted. Radiographically, a well-delimited peaklike radiolucent area promoting root divergence was observed. The lateral incisor failed in responding positively to the ...

http://dx.doi.org/10.1590/0100-3984.2014.0134 is the most common symptom, usually occurring as a result from inflammation or ileal volvulus. Meckel’s diverticulum rupture is rarely found in neonates, occurring in less than 10% and manifesting at radiography as pneumoperitoneum. In such situations, the differential diagnosis should be made with necrotizing enterocolitis, since this disease is re...
