Kimura disease (KD) is a chronic inflammatory disorder with a secondary vascular component. The aetiology is unknown. It is mostly reported in Asian populations and has a 6:1 male/female ratio. Clinical manifestation is often as a painless unilateral cervical lymphadenopathy or as subcutaneous masses in the head and neck region. KD is generally limited to the skin, lymph nodes and salivary glands.
Conventional management includes conservative, intra-lesional steroids, chemotherapeutic drugs, radiotherapy and surgical excision. Unfortunately none of which are curative as the lesion inevitably recurs.
Photodynamic therapy has previously been shown to reduce the bulk of vascular malformations.
