| cellulitis | <dermatology> An acute, diffuse, spreading, oedematous, suppurative inflammation of the deep subcutaneous tissues and sometimes muscle, which may be associated with abscess formation. It is usually caused by infection of an operative or traumatic wound, burn or other cutaneous lesion by various bacteria, but group A streptococci and Staphylococcus aureus are the most common aetiological agents. Cellulitis may also occur in immunocompromised hosts or it may follow erysipelas. It tends to spread to tissue spaces and cleavage planes owing to bacterial elaboration of large amounts of hyaluronidases that, break down polysaccharide ground substance, fibrinolysins that digest fibrin barriers and lecithinases that destroy cell membranes. Clinical manifestations include an area of oedema, warmth and tenderness with indistinct margins. Compare: erysipelas. (13 Nov 1997) |

| elbow, cellulitis of the | Inflammation of the skin around the elbow due to infection (cellulitis) commonly occurs as a result of abrasions or puncture wounds permitting bacteria on the surface of the skin to invade the deeper layers of the skin. This causes inflamed skin characterised by heat, redness, warmth, and swelling. The most common bacteria that cause cellulitis include Staphylococcus ( Staph ) and Streptococcus ( Streop ). One can have an associated low-grade fever. Cellulitis generally requires antibiotic treatment, either orally or intravenously. Heat application can help in the healing process. (12 Dec 1998) |
| eosinophilic cellulitis | <syndrome> Recurrent cellulitis followed by brawny edematous skin lesions, or a less acute presentation of papular, annular, or gyrate skin lesions which are sometimes urticarial; affected skin and subcutis are heavily infiltrated by eosinophils and histiocytes, with scattered small necrotic foci (flame figures) of varied aetiology; sometimes follows an arthropod bite. Synonym: eosinophilic cellulitis. (05 Mar 2000) |
| epizootic cellulitis | A highly contagious viral disease caused by equine arteritis virus, member of the family Togaviridae, and characterised by a high fever and respiratory and digestive tract signs; the essential lesions involve smaller arteries, with necrosis which may be followed by thrombosis, infarction, haemorrhages, and oedema; abortion is a common result. Synonym: epizootic cellulitis, equine typhoid. (05 Mar 2000) |
| accessory nerve trunk | Part of the accessory nerve formed within the cranial cavity by the union of the cranial and spinal roots, which then divides within the jugular foramen into internal and external branches, the former uniting with the vagus, the latter exiting the foramen as in independent branch which is commonly considered to be the accessory nerve.

| bathing trunk nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |
| bifurcation of pulmonary trunk | The division of the pulmonary trunk into right and left pulmonary arteries. Synonym: bifurcatio trunci pulmonalis. (05 Mar 2000) |
| brachiocephalic trunk | The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm. (12 Dec 1998) |
| bronchomediastinal trunk | A lymphatic vessel arising from the union of the efferent lymphatics from the tracheo-bronchial and mediastinal nodes on either side. On the left side, it may be largely replaced by direct drainage into the thoracic duct. Synonym: truncus bronchiomediastinalis. (05 Mar 2000) |
| vagal trunk | One of the two nerve bundles, anterior and posterior, into which the oesophageal plexus continues as it passes through the diaphragm. Synonym: truncus vagalis. (05 Mar 2000) |
