title: [Pre-auricular angiomyxoma in a child].
abstract: Myxomas are rare benign tumours in adolescents and adults with a predominant manifestation in the region of the maxillary and mandibular bone. A case of a cystic, slowly growing tumour in the right preauricular region is presented. During operation the tumour was completely encapsulated by connective tissue and showed a lobular shape on the cut surface with small cystic cavities. Histologically a myxomatous tissue was seen with a prominent and reticular capillary system like an angiomyxoma. The pathogenesis remains unclear. The definite diagnosis is established by histology. Histological and immunohistochemical differentiation between different benign mixed tumours should include myxomatous neurinomas and lipomas as well as myxomatous transformed histiocytomas. Surgery is the treatment of choice. After a follow-up for more than two years the patient is free from clinical symptoms.
