Abstract

Background: Clear cell tumor of the lung is a rare and very unusual benign pulmonary tumor. This tumor is called sugar tumor because of the abundance of glycogen on its cells.
Aim: To report a case of sugar tumor and discuss clinical, evolutive features and diagnosis difficulties of this tumor.
Case report: A case of 75 years old woman presenting as a round pulmonary opacity. Computed tomography (CT) scans showed in the left lower lobe a solitary pulmonary solid tumor with central calcifications. The patient underwent tumor resection. Pathologic examination, including immunohistochemical studies, revealed a benign clear cell tumor, so-called “sugar tumor”.
Conclusion: It’s the second case reported in Tunisia. This very rare tumor of the lung is characterized by some immunohistological features. Its evolution is favourable after surgery.

Keywords:
