1/3. Rare benign tumours of oral cavity--capillary haemangioma of palatal mucosa: a case report.Haemangiomas are benign tumours composed of blood vessels, they are probably developmental rather than neoplastic in origin. Haemangiomas are often present at birth but may become more apparent during life. The tumours appear as a flat or raised reddish-blue lesions and are generally solitary. They are occasionally seen on the palatal mucosa. Haemangiomas are classified on the basis of their histological appearance as capillary, mixed, cavernous or a sclerosing variety that tends to undergo fibrosis. Their differential clinical diagnosis is based on appearance. The tumours may be slowly progressive, involving extensive portions of the superficial and deep blood vessels. Function may be affected where development of the lesion is extra-invasive. Colour change on pressure is a common finding with return to the original colour on withdrawal of pressure. The case presented here was referred because of swelling and recurrent periodontal bleeding. The lesion was diagnosed as a capillary haemangioma through histopathology. Although different therapeutic procedures have been reported, in this case surgical excision was carried out under general anaesthesia following hospitalization. Despite their benign origins and behaviour, haemangiomas in the region of oral cavity are always of clinical importance to the dental profession and require appropriate clinical management. Dental practitioners and oral surgeons need to be aware of these lesions because they may pose serious bleeding risks.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/3. Facial swelling and gingival enlargement in a patient with sickle cell disease.Sickle cell anemia is a frequent hemoglobinopathy in the Caribbean. While vaso-occlusion induced tissue injury in sickle cell anemia is common in various organs, orofacial lesions are rare. A 14-year-old Afro-Trinidadian boy suffering from sickle cell anemia developed an acute facial swelling, mimicking facial cellulitis of dental origin, which was caused by sickle cell-related hemorrhage. He also exhibited gingival enlargement, considered to be an outcome of repeated hemorrhagic episodes and fibrous repair. A new finding is the presence of erythrocyte-filled intraepithelial blood vessels in the gingival epithelium. We hypothesize this phenomena is a tissue response to hypoxia that occurs in sickle cell disease.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
3/3. Arteriovenous malformation of the mandible: report of a case with a note on the differential diagnosis.arteriovenous malformations are extremely rare conditions that can result from congenital or acquired abnormalities in the structure of blood vessels; they are potentially fatal. arteriovenous malformations may be asymptomatic or may show various signs and symptoms including soft tissue swelling, pain, changes in skin and mucosal color, erythematous and bleeding gingiva, bruit, and paresthesia. Radiographically, there are no pathognomonic features. The present case illustrates an arteriovenous malformation in a 16-year-old Hispanic female. The case report is unique because the malformation was previously interpreted as a pathosis of pulpal origin and was initially treated as such, although the tooth showed no gross or radiographic dental caries. A broad view of the diagnostic imaging, radiographic differential diagnosis, treatment, and histopathologic description is also presented.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
