Abstract
Introduction
Sarcoidosis is a multisystem granulomatous disorder
of unknown aetiology most co~nonly affecting young adults
and presenting most frequently with bilateral hilar lymphadenopathy,
pulmonary infiltration, and skin or eye lesions.
The diagnosis is established most securely when clinicoradiographic
findings are supported by histologic evidence
of widespread noncaseating epithelioid cell granulomas in
more than one o~gan or a positive kveim. Siltzbach skin test
(James et al., 1976 ). Sarcoidosis appears to be much less
frequent in tropical than in temperate areas. It has been
thought to be rare among chinese (Presentand Siltzbach,l967J.
Sarcoidosis is mainly a disease of young adults; of newly
diagnosed cases, 70 per cent are between 20 and 40 years
of age. There is a slight female predominance (Douglas,
1961) •
Patients with sarcoidosis may present with a wide
variety of symptoms and signs involving many organs and
tissues (Longcope and Freiman, 1952) .
