An incidental finding ‒ Solitary fibrous tumor of the pleura

Abstract

A 46-year-old female, with no previous history of respiratory complaints, was found to have a lesion in the left lower zone on chest X-ray during preoperative evaluation for undergoing hysterectomy in view of vaginal prolapse. Computed tomography (CT) of the chest showed a well-defined lobulated pleural-based lesion with smooth margins in the left lower lobe measuring 9.3 cm × 5.3 cm. She underwent CT-guided lung biopsy which showed a mesenchymal neoplasm. Hence, uniportal Video assisted thoracoscopic surgery (VATS) was done and a biopsy Histo-pathological examination (HPE) sent showed pleomorphic spindle cells with little cytoplasm and immunohistochemistry showed vimentin, CD34, STAT 6 positivity, and pan-cytokeratin negativity, consistent with solitary fibrous tumor of the pleura.
