Metastatic Pulmonary Calcification with the Coexistence of known Esophageal Carcinoma: Case Report and Literature Review.

Metastatic pulmonary calcification, also called MPC, is a metabolic abnormality resulting in pulmonary calcium deposition. Our patient is a known biopsy-proven SCC of the mid-esophagus with extensive widespread alveolar calcifications on a background of renal and ureteric stones. It is important to note that, although the disease is known as metastatic, it is a rather benign lung illness with an excellent long-term prognosis. To our knowledge, this kind of cohabitation has never been documented before.
