is a condition that involves inflammation of the tissues under the surface. This may cause rigid tissues and difficulty opening the mouth. Benign soft tissue neoplasms 1. Peripheral nerve sheath tumours most commonly are traumatic neuromas, a reactive response to trauma (1), neurilemmoma and neurofibroma which are large growing painless tumours usually found on the tongue (3). Neurofibroma may occur as a benign solitary lesion but can present as multiple lesions associated with (Von Reckllinghausen’s Disease) neurofibromatosis (4). They can be preceded by café au lait pigmentation spots on the skin, and as they grow can become very disfiguring (4). Malignant change can occur in neurofibromatosis but very rarely in single lesion presentation. Mucosal neuromas can be associated with other conditions such as Multiple Endocrine Neoplasia (MEN) Syndrome and may precede thyroid cancer. (1, 4) 2. Lipoma and fibrolipoma, are tumour of adipose tissue, or fat, giving them a yellow appearance which varies according to fat content (1, 4). They are usually soft, mobile, slow growing painless and occur mostly in middle age or the elderly. 3. Granular Cell Tumour is also a tumour arising from neural cells, though it was incorrectly thought to arise from muscle cells and therefore previously called Granular Cell Myoblastoma (4), It also is slow growing large painless and occurs mostly in the tongue (1, 3). 4. Congenital Epulis, also known as Congenital Granular Cell Tumour (but not related to Granular Cell Tumour) occur mostly on the upper gum, the maxillary alveolar ridge, of newborns, predominantly females (4). Rarely, they occur elsewhere, usually the tongue. They are usually self-resolving (1). 5. Angiomas – vascular tumours: haemangioma, lymphangioma, venus varix (2). Angiomas are difficult to classify as previously they were considered hamartomas, benign tumour-like malformations (6) but there is debate if they are developmental abnormality, true benign tumour or hamartoma, or can be either (1, 4, 5). Haemangiomas are common in the oral mucosa but can occur in other structures such as salivary glands (4), and can be congenital (from birth) or develop in childhood. Congenital lesions can resolve spontaneously (involute) but those that develop later usually continue to slowly grow. They are usually dark red-purple or blue, soft, sometimes fluctuant (5) and painless. They commonly blanch on pressure. Usually solitary, they can occur as part of syndromes such as Sturge-weber Syndrome affecting the trigeminal nerve. They are at risk of trauma with subsequent excessive bleeding,
