Multiple primary malignant tumors (MPMTs) are rarely seen among the patients with malignant neoplasms. Moreover, the existence of five MPMTs in the same patient is an extremely rare phenomenon. In this case, a 42‐year‐old male patient developed five metachronous MPMTs within 16 years and the duration between each malignant tumor shortened with the progression of the disease. Multidisciplinary treatments were used on this patient and he fought against the cancers until the end of his life. Our report provides us with a new awareness of MPMTs, which should be considered when we come across with cancer patients who develop various unexplainable symptoms after the diagnosis of the first neoplasm.
