Abstract

Lamia Ouafi, Elizabeth Longchampt, Edouard Sage and Catherine Daniel

Aims: Pulmonary sclerosing pneumocytoma is a rare benign neoplastic tumour. It is often discovered incidentally
in chest X-ray or chest CT scan performed for others reasons. We present here a case of pulmonary sclerosing
pneumocytoma and discuss the clinical, histopathological features and treatment of this tumour in light of the data
of the literature.
Methods and Results: We report the case of pulmonary sclerosing pneumocytoma found in 66-year-old woman
on chest CT scan performed for staging of a breast cancer. The patient underwent a left lower lobectomy and ipsilateral
médiastinal lymph node dissection because frozen section examination suggested papillary adenocarcinoma.
Conclusion: Most occurrences of pulmonary sclerosing pneumocytoma is often discovered incidentally. It is a
rare benign tumour that frozen section examination is unable to diagnosis them in 25 to 56% of cases. The prognosis
after surgical resection is excellent.
