Abstract
A 5 l-year-old housewife was referred to our section for the evaluation of an abnormal chest roentgenogram showing a solitary round mass shadow in the left lower peripheral lung field. The mass was characterized as a well circumscribed 22-cm homogeneous nodule without notching. There were no malignant signs on chest tomography and computed tomographic scan. No abnormalities were revealed by physical and haematobiochemical examinations. Inspection of the airways by bronchoscopy yielded normal results. Under fluoroscopic guidance, transbronchial biopsy forceps and a bronchial brush could not pass into the mass. TBNA was performed using a retractable 21-gauge needle. Cytologic smears stained by the Papanicolaou technique revealed hyperplastic alveolar epithelial cells of a somewhat dysplastic nature showing glandular cell arrangement [Plate l(a)] and macrophages, some of which had haemosiderin pigments [Plate l(b)]. Polynucleated giant cells, fibroblasts and endothelial cells were also seen. Cytologic material obtained by TBNA did not show the full range of features of SH, however, we could make the diagnosis of this entity interpreting cytologic features combined with the chest radiograph in a middle-aged woman. As the patient had an operation for colon cancer last year, she underwent left lower
