Metastatic pulmonary calcification with the coexistence of known esophageal carcinoma: Case report and literature review

Abstract

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.
