RESUMO
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.

Extramedullary plasmocytoma (EMP) is a rare cell neoplasm most frequently localised in the upper respiratory tract. We report the case of a 43 year-old-man, with an unusual presentation of EMP developing in the mediastinum, two years after a diagnosis of solitary plasmocytoma of the bone which was successfully treated by local irradiation. In this aggressive presentation, we decided to perform an autologous hematopoietic stem cell transplantation. Two months after transplantation, CT scan showed disappearance of the mediastinal mass and immunofixation of the serum was normal. Selected cases of diffuse EMP, could benefit from intensive treatment followed by autologous hematopoietic stem cell transplantation.
