ABSTRACT
Of unknown aetiology, although a transmissable agent is postulated. Widely disseminated lesions are common; lungs, lymph nodes, skin, eyes, skeletal tissues and nervous system involvement are all described. Various immunological disturbances are described, but their contribution to the clinical course is unclear. Orofacial sarcoid is not very common. Cutaneous sarcoid affecting the face is more so. Labial biopsy may demonstrate granulomas. Kveim testing may provoke their formation and serum acetylcholinesterase (ACE) levels, although not very specific, may aid diagnosis. Corticosteroids may be inhibitory, particularly for lung disease and in uveoparotid fever. Intra-lesional steroid injections of triamcinolone are used with benefit.
