ILD with a granulomatous component
(Fr: PnP avec granulomes). Characteristically nonnecrotizing, noninfectious, sterile granulomas. Although this is a pathologic pattern, the condition is suspected on a miliary appearance on imaging. Hilar/mediastinal lymphadenopathy can be present. May mimic pulmonary and/or systemic sarcoidosis. Concomittant skin lesions may show granulomas. A confirmarptory lung biopsy may be required (See under Pathology XIV). Careful exclusion of mycobacterial, fungal and Pneumocystis infection is crucial (See PMID 10678649, 18054121, 17257125).
