Extraskeletal chondrosarcoma (ECS) is a rare malignant neoplasm of bone or soft-tissue origin, characterized by the presence of spindle cells admixed with well-differentiated cartilage or chondroid stroma. A case of ECS is reported in a 102-year-old woman who presented with a painful swelling of 2 cm in the left buccal vestibular area....

Background: Ectomesenchymal chondromyxoid tumour (ECT) is a rare, benign neoplasm of uncertain histogenesis, which appears to exclusively involve the oral cavity, particularly the tongue. Case Report: We report the case of a 27-year-old woman with a 0.7 cm tumoral lesion of 3 months' duration on the dorsum of the tongue. Histologically, it...

Gingival metastases from embryonal carcinoma are very rare and often associated with widespread disease and poor prognosis. Because of their indistinct clinical appearance, they may be difficult to discriminate from more frequent gingival hyperplastic or reactive lesions. The case of a 35-year-old man who presented with a swelling in the left...

Nevus lipomatosus cutaneous superficialis (NLCS) is an extremely rare hamartomatous disorder comprising of ectopic mature adipose tissue. The lesions take the form of large, slow-growing, sessile or pedunculated tumors. We report the case of an 11-year-old boy with NLCS, dating back many months, that was growing as a cuff around the parotid...

The adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin, composed of odontogenic epithelium and characterized by slow but progressive growth. We report a rare case of AOT in an 18-year-old, who presented with a palpable bony-hard swelling in the anterior maxillary region. The tumor was radiographically well-defined,...

Hyalinizing clear cell carcinoma (HCCC) is very rare in the oral cavity, arising more frequently in the minor salivary glands. We present the case of a 57-year-old woman with a swelling on the anterior palatoglossal arch of 2x1 cm size. An incisional biopsy was taken and histological examination revealed typical clear cells arranged in...

The aim of this study was to analyse, in vitro, the chemical and mechanical properties of a new fibre retainer, Everstick, comparing its characteristics with the requirements for an orthodontic retainer. Chemical analysis was used to examine seven fibre bundles exposed to a photocuring lamp and then to different acids and resistance to...

AIM: The aim of this paper is to examine the clinical and histological feature of oral tumours of neural derivation and discuss their treatment. METHODS: Between 1999 and 2004, 11 patients (6 females, 5 males; age range 28-66 years) were treated for tumours classified as being of neural origin; they were all myoblastomas or granular cells...

Hemangiopericytoma/solitary fibrous tumor is a very rare tumor of uncertain malignant potential. About 300 such cases have been reported since 1942, when Stout and Murray described these tumors as "vascular tumors arising from Zimmerman's pericytes". Under the World Health Organization (WHO) classification, hemangiopericytomas and solitary...

Primary (extranodal) non-Hodgkin's lymphoma (NHL) of the oral cavity is relatively rare. We report a case of NHL involving the left anterior mandibular gingiva of a 56-year-old man. He was initially treated with antibiotics and root canal therapy of the lower lateral incisor as there was a history of trauma to this area. The adjacent lateral...

Liposarcoma is one of the commonest soft-tissue sarcomas, but very rare in the oral cavity. We present two cases of liposarcoma of the oral cavity, together with the related clinical, histopathological and immunohistochemical findings: one affecting the cheek of a 62-year-old man and the other the gingival maxillary tuber of a 41-year-old...

The term fibromatosis indicates a proliferation of well-differentiated fibroblasts and myofibroblasts that develops in the soft tissue. This tumor has been considered locally aggressive because of the infiltrative growth pattern, but does not metastasize. Its occurrence in the head and neck region is not common, and very sporadically it may...

Fibrosarcoma (FS) is a malignant mesenchymal neoplasm of the fibroblasts that rarely affects the oral cavity. Two cases of primary FS of the jaws with intraosseous growth (2 men, aged 53 and 71 years) are described. Microscopically, in one case the tumor showed an intense proliferation of spindle-shaped cells, varying little in size and shape...

Objective: Surgical management of salivary gland diseases has always been challenging because it carries a considerable risk of nerve damage. This study evaluates an innovative ambulatory laser-aided technique that may be an alternative to traditional treatment, and presents our 5-y experience of salivary gland excision. Materials and Methods:...

Ameloblastic carcinoma is a very rare malignant odontogenic neoplasm of the mandible and maxilla, accounting for some 66 reported cases. The case of a 68-year-old man who presented a fistula with orosinus communication of 14-year duration that, after anti-aggregant therapy, began bleeding is reported. The initial microscopic evaluation of the...

Objective: Red and near-infrared laser irradiation is reported to have a range of biological effects on cultured cells and different tissues, leading to the hypothesis that laser light can affect energy metabolism. Increased adenosine triphosphate (ATP) synthesis has been reported in cultured cells and rat brain tissue after irradiation at...

Mesenchymal chondrosarcoma (MCS) is a rare malignant neoplasm of bone or soft tissue origin, locally aggressive, rare in the oral cavity, of which fewer than 100 cases have been reported in the English literature. This is the first case described of this type of tumor affecting the coronoid process. The report describes a unique case of MCS in...
