Chemotherapy-induced oral mucositis in a patient with acute lymphoblastic leukaemia.

BACKGROUND: Oral mucositis is the main complication of chemotherapy and radiotherapy used in the treatment of cancer. Phototherapy has proven effective in the treatment of mucositis, as it accelerates the tissue healing process and has both analgesic and anti-inflammatory properties. CASE REPORT: This paper reports the case of a paediatric patient with oral mucositis stemming from chemotherapy employed for the treatment of acute lymphoblastic leukaemia. TREATMENT: The lesions were treated daily with a light-emitting diode (LED). FOLLOWUP: Remission of the lesions occurred after 10 days of treatment. CONCLUSIONS: LED was effective in the treatment of mucositis, as it diminished pain symptoms and accelerated the tissue repair process.
