BUERO, Agustín et al. PEComa of the lung. Medicina (B. Aires) [online]. 2022, vol.82, n.6, pp.963-966. ISSN 0025-7680.

Clear cell ‘‘sugar’’ tumor of the lung is a rare benign tumor arising from perivascular epithelioid cells (PECs). They belong to a group of mesenchymal neoplasms called PEComas. Although widely presumed as benign, due to their rich vascular stroma they are usually avid for the different types of contrast agents used in imaging studies, mimicking a malignant lesion. We report the case of a 66-year-old man in whom a solitary pul monary nodule was discovered during oncological staging for an adenocarcinoma of the prostate who underwent an anatomical pulmonary segmentectomy. The final pathology result was a perivascular epithelioid cell tumor (pulmonary PEComa or clear “sugar” cell tumor).

Keywords : Pulmonary nodule; PEcoma; Clear cell ‘‘sugar’’ tumor.
