[Intra-alveolar hemorrhage revealing pheochromocytoma].

We report a case of pheochromocytoma revealed by alveolar hemorrhage in a 51-year-old woman. Pheochromocytomas are rare tumors deriving from the chromaffin tissue, and which clinical manifestations are highly variable, mostly unspecific, and very rarely concern the lung. Therefore, the diagnosis is often missed or delayed. However, without correct diagnosis and subsequently adapted treatment, the disease may be fatal. Thus, clinicians should be aware of the possible diagnosis of pheochromocytoma in patients presenting hemoptysis of an unknown origin.
