Rare Benign Tumour (rare + benign_tumour)
Selected AbstractsRare benign tumours of oral cavity , capillary haemangioma of palatal mucosa: a case reportINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 2 2000Aydan Açikgözsurname 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. [source] Oral myofibromatosis: an unusual cause of gingival overgrowthJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 11 2002Case report, review of the literature Abstract Background:, This case report describes a rare benign tumour, which presented as discrete areas of gingival hyperplasia affecting both the mandible and the maxilla. Method:, Surgical excision of the lesions was carried out under local anaesthetic. Histopathological examination confirmed the diagnosis of oral myofibromatosis. Results: The condition responded to surgical excision and appears to have limited growth potential. It affects a wide spectrum of ages and can be alarming due to rapid enlargement and ulceration, so careful diagnosis is important to avoid unnecessary aggressive treatment. Zusammenfassung Orale Myofibromatose: eine ungewöhnliche Ursache einer gingivalen HyperplasieFallbericht und Literaturüberblick Hintergründe: In dem vorliegenden Fallbericht wird ein seltener benigner Tumor, der sich als klar abgegrenzte Bereiche einer gingivalen Hyperplasie darstellte und durch den sowohl Mandibula als auch Maxilla betroffen waren, beschrieben. Methodik: Unter lokaler Betäubung wurde eine operative Exzision der Läsionen vorgenommen. Eine histopathologische Untersuchung bestätigte die Diagnose einer oralen Myofibromatose. Ergebnisse: Die Erkrankung sprach auf die operative Exzision an und scheint lediglich über begrenztes Wachstumspotential zu verfügen. Eine breites Spektrum an Altergruppen ist betroffen und die Störung kann aufgrund einer rapiden Vergrösserung und Ulzerierung alarmierend sein. Um unnötige aggressive Therapien zu vermeiden ist eine sorgfältige Diagnose erforderlich. Résumé Myofibromatose buccale : une cause inhabituelle d'hypertrophie gingivale. Rapport d'un cas et revue de la littérature Les myofibromatoses sont des néoplasmes bénins rares qui peuvent se présenter soit de maničre solitaire soit en lésions multiples. Un diagnostic attentif de cette tumeur bénigne est important pour éviter une thérapie aggressive non-nécessaire. Avec un traitement chirurgical conservateur, le pronostic est excellent. [source] Hamartoma of the breastJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 2007A Murat SUMMARY Breast hamartoma is a rare benign tumour that leads to unilateral breast enlargement without a palpable localized mass lesion. Histologically, a hamartoma consists of varying amounts of adipose, gland, fibre and smooth muscle tissue. The characteristic mammographic appearance of hamartoma of breast has distinct mammographic features with circumscription and fat and soft-tissue density surrounded by a thin radiopaque capsule or pseudocapsule. Ultrasonographic findings include a well-defined mass lesion consisting of echogenic and sonolucent areas. We present histopathological and radiological findings of a 42-year-old female patient with breast hamartoma who has no complaint.

Clinically, clear cell acanthoma is characterized by a ,stuck on' appearance of a nodule or dome-shaped plaque that usually occurs on the legs of middle-aged or elderly persons. We observed an unusual case of polypoid clear cell acanthoma on the right thigh of a 58-year-old male. [source] Hepatic myelolipoma incarcerated in a peritoneopericardial diaphragmatic hernia in a catAUSTRALIAN VETERINARY JOURNAL, Issue 6 2010RM Wouda Hepatic myelolipoma incarcerated in a peritoneopericardial diaphragmatic hernia was diagnosed in an 11-year-old, desexed female Persian cat. The cat was initially referred for investigation of tachypnoea and dyspnoea. Peritoneopericardial diaphragmatic hernia is a common incidental finding in cats and is usually asymptomatic. Myelolipoma is an extremely rare benign tumour, composed of extramedullary haematopoietic cells and adipose tissue. Myelolipomas are hypothesised to result from metaplastic alteration, rather than a neoplastic process, although this theory cannot be substantiated. The present case is only the fourth report of such an unusual occurrence in cats and displays significant differences to previous reports. Hepatic entrapment and burgeoning of the mass within the pericardial sac resulted in cardiac tamponade and overt signs of right-sided cardiac failure. Surgical intervention was successful and despite concerns regarding the cat's clinical presentation and the gross appearance of the lesion(s), a good long-term outcome is anticipated. [source] Type 1 segmental cutaneous leiomyomatosisCLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 8 2002K. Lang Summary Cutaneous leiomyomas are rare benign tumours of the skin, which present in multiple disseminated, segmental or solitary forms. The pathogenesis of segmental cutaneous leiomyomatosis is not yet fully known. Most recently two types of segmental manifestation of autosomal dominant inherited diseases were postulated. Type 1 reflects heterozygosity for the underlying mutation with a clinical picture similar to that in a non-mosaic phenotype. In type 2, loss of heterozygosity leads to homo- or hemizygosity with a pronounced segmental manifestation of lesions in the affected segment. In our patient the lesions were restricted to one segment and therefore she most probably has a type 1 segmental cutaneous leiomyomatosis. [source] | ||||||||||
