Introducing a New Term: Metastasoptysis- A Case Report

Abstract

Pulmonary metastasis is not uncommon in the follow-up of patients with primary malignancy, but the expectoration of metastatic tumor is extremely rare. Metastases from renal and breast malignities may rarely lead to tumor expectoration with less common colorectal carcinomas. In this case report, expectoration of a metastatic tumor in a patient who had diagnosed with colon adenocarcinoma and pulmonary metastasis was presented. We named this quite rare condition as “metastasoptysis”.
