Hemoptysis, a common sign of diffuse alveolar hemorrhage, can be caused by multiple factors, both infectious and noninfectious. A 45-year-old male with hypertension, obstructive sleep apnea, and stage IV pulmonary sarcoidosis with cardiac involvement, presented with a two-month history of cough and acute nonmassive hemoptysis with hypoxia. A chest CT showed ground glass consolidation and interlobular septal thickening, concerning for diffuse alveolar hemorrhage. Flexible bronchoscopy confirmed diffuse alveolar hemorrhage; microbiological analyses of bronchoalveolar washings did not reveal a causative organism. Mycoplasma pneumoniae-specific IgM in serum studies was consistent with mycoplasma pneumonia as the most likely etiology of this patient's diffuse alveolar hemorrhage and resultant hemoptysis. This report points to the need to consider atypical mycoplasma pneumonia as a possible etiology of hemoptysis in patients with underlying sarcoidosis.
