1/2. 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 = anaesthesia (Clic here for more details about this article) |
2/2. Extensive bleeding during surgical treatment for gingival overgrowth in a patient on haemodialysis--a case report and review of the literature.Before performing renal transplantation, a most important concern is to control any infection, including oral infections before transplantation. The bleeding diathesis of patients with uraemia is a significant clinical concern, especially when surgery is required. A 44-year-old female patient on haemodialysis was referred for evaluation of gingival overgrowth. The patient was planning a renal transplantation two months later. As the lesions were not considered successfully treatable before transplantation, a gingivectomy and teeth extraction was performed. In pre-operative examinations, an abnormal bleeding time was not detected and other coagulation tests were normal. Under general anaesthesia, 19 teeth were extracted and overgrown gingiva was removed. During the operation, extensive blood loss of 1650ml occurred and four units of concentrated red blood cells were transfused. This study suggests that patients with renal failure undergoing dental surgery require careful pre-surgical evaluation including assessment of their coagulation ability.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
