Biopsy never diagnostic. Always revisit diagnosis or consider additional pathologic processes when either clinical course or clinical manifestations deviate from the expected or the typical.Consider:Not sarcoidosis Sarcoidosis plus independent process-e.g. infection, PE, CHFSarcoidosis plus associated process- e.g. CVID, CTD, othersTreatment effectsRare manifestations of sarcoidosis do occur.

14. Sarcoidosis Associated Pulmonary Hypertension Pulmonary hypertension prevalence
6% unselected pulm sarcoidosis patients
50% patients with dyspnea disproportionate to PFTs
70-80% in advanced lung disease
Higher when measuring exercise induced pulm htn
Multiple potential mechanisms
Bronchovascular distribution of inflammation
Advanced fibrocystic lung disease (loss of pulmonary capillary bed)
Extrinsic compression of pulmonary arteries by LN, mediastinal fibrosis
Cardiac sarcoidosis with systolic, diastolic dysfunction
Hypoxic vasoconstriction
Primary pulmonary vascular involvement (granulomatous arteritis)
Veno-occlusive disease (rare)
16. Cardiac Sarcoidosis: Clinical Manifestations Common
Arrhythmias
Heart block/conduction defects
Congestive heart failure
Sudden death
