• Melanocytic Tumours

  Melanocytes are cells that produce a pigment called melanin. They are found in many parts of the body where there is pigment, particularly skin, hair and eyes.

• Multicentric Squamous Cell Carcinoma in Situ ("Bowen-Like" Disease)

  Squamous cell carcinoma in situ is a disordered growth of the skin epidermis which may extend to include epithelium of the upper part of the hair follicles.

• Nasal Tumours

  Most cancers originate from the lining of the nose (epithelium). Benign tumours (adenomas) are rare but if they are surgically removable, they are curable. Malignant tumours (carcinomas) are more common with many different types.

• Necrosis of the Femoral Head

  The hip is a ball and socket joint of the hip and necrosis or death of the femoral head means that the ball part of the joint is no longer properly functioning. This is because during the growing phase the bone of the femoral head becomes deprived of its blood supply and dies.

• Neuroendocrine Tumours - Carcinoids

  Neuroendocrine cells produce rare tumours (carcinoids, Merkel cell tumours and neuroendocrine tumours). In general, the tumours are slow growing but will eventually spread (metastasize) to other parts of the body.

• Neuroendocrine/Chemoreceptor Tumours - Chemodectomas

  Chemodectomas are tumours of the chemoreceptors. They include both benign (non-spreading) adenomas and malignant carcinomas.

• Oral Tumours - Epuli, Basal Cell Carcinomas and Ameloblastomas

  An epulis (plural epuli) is the clinical name for a swelling on the gums. Several different tumours share this name, often of different origins including the tooth-socket lining and lining epithelium of the mouth.

• Oral Tumours - Fibrosarcomas and Related Tumours

  Oral fibrosarcomas are rapidly growing, malignant tumours originating from the fibrous connective tissue of the mouth. The tumours are rarely cured by surgical removal.

• Oral Tumours - Melanoma

  Oral melanoma (malignant melanoma or melanosarcoma) is a tumour of melanin pigment producing cells (melanocytes). The cancers are rapidly growing and unfortunately are rarely completely cured by surgical removal.

• Oral Tumours - Papillomas and Fibropapillomas ('Sarcoids')

  Oral papillomas are benign tumours of the epithelial lining of the mouth and throat caused by papillomaviruses. The viruses are specific for that species of animal and fairly site specific but can be transmitted to skin or eyes if the protective outer epithelium is damaged.
