Sarcoidosis initially occurring as apical infiltrate and pleural reaction

A 21-year-old black man had pleuritic pain as the initial symptom of his sarcoidosis. Chest roentgenographic examination showed an infiltrate in the left upper lobe and a left pleural thickening. Sarcoidosis was diagnosed by pulmonary biopsy. Thus, sarcoidosis may closely mimic tuberculosis by initially occurring as predominantly apical infiltrates and pleural reaction.
