Recognize the patterns of sarcoidosis presentation.

Explanation:

Lofgren's syndrome(Triad) is diagnostic of Sarcoidosis and needs no tissue confirmation. It consists of Bilateral hilar adenopathy, Erythema nodosum and polyarthritis.

90% of patients have pulmonary involvement and commonest presentation being BILATERAL HILAR ADENOPATHY.

For tissue diagnosis biopsy lesions other than erythema nodosum.

Steroid therapy (>6 months therapy)is indicated if patient has any of the following:

CNS or CARDIAC involvement, uveitis, Cosmetic disfigurement, hypercalcemia or hypercalciuria significant enough to cause renal impairment.

Pulmonary sarcoidosis should only be treated if there are respiratory symptoms or extensive involvement as per CXR or PFT.

Cough due to endobronchial lesions can be treated with inhaled corticosteroids.
