Doege–Potter syndrome in benign relapse of solitary fibrous tumour of the pleura: An exotic clinical setting

Solitary fibrous tumors are mesenchymal neoplasms that make up 2% of soft tissue tumors. Doege-Potter syndrome (DPS) occurs between 5-10% of patients with solitary fibrous tumor of the pleura (SFTP). Little is mentioned about DPS in the relapse setting, where malignant transformation should always be ruled out (until 12% of cases) according to tumor size, histopathologic aspects (including mitotic index) and immunohistochemical markers. This is the first case of Doege-Potter syndrome in the setting of a fibrous tumor relapse of the pleura without malignant transformation described in Colombia.
