- Adrenocortical carcinoma is a rare neoplasm and it has an invariably lethal prognosis. We report here on the fine needle aspiration cytologic findings of a solitary metastatic pulmonary adrenocortical carcinoma in a 24-year-old woman. The aspirate smears were very cellular and they were composed of a monomorphic population of large polyhedral cells with abundant granular or vacuolated cytoplasm, and the cells were predominantly singly scattered in a necrotic background. Multinucleated pleomorphic tumor cells were also found. Pleomorphic nuclei with thickened nuclear membranes were impinging on the cell membranes.
Mitotic activity was occasionally seen. The cytologic findings of pleomorphic cells with microvacuolated cytoplasm and the presence of vague gland-like sheets, as well as the patient's history of undergoing adrenalectomy for primary adrenocortical carcinoma helped the pathologist reach the diagnosis of metastatic adrenocortical carcinoma. Here, we focus on the cytologic differential points of metastastic pulmonary adrenocortical carcinoma and primary pulmonary carcinoma, especially large cell carcinoma.

- BACKGROUND
This study was performed to examine the significance of the circumferential resection margin (CRM) involvement by a tumor on the postoperative survival after esophageal cancer surgery.
METHODS
Fifty nine resected cases of esophageal cancers were retrospectively reviewed. The presence of a tumor either at, or within 1 mm of, the CRM was recorded. By an immunohistochemical study for Ki-67, the Ki-67 differential grades (Ki-67 DG) were defined according to the differences between the Ki-67 labeling indices of the central and of peripheral areas of the tumor nearest to the CRM: Ki-67 DG 0 (< or =10%) and Ki-67 DG 1 (>10%). The CRM involvement was correlated with the clinicopathological factors, Ki-67 DG and survival data.
RESULTS
CRM involvement was found in 26 (44.1%) of the 59 cases. There were significant differences in the cases, both with and without CRM involvement of tumor cells, in relation to lymph node metastasis, lymphovascular, perineural invasions and tumor stage (p<0.05). Ten (38.3%) of the 26 with, and 3 (9.1%) of 33 cases without, CRM involvement, showed Ki-67 DG 1 (p=0.007). The 3-year survivals of patients with and without CRM involvement were 26.8 and 61.8%, respectively (p=0.003).
CONCLUSIONS
These results show that the CRM involvement status may be used as a predictor of survival after esophageal cancer surgery, and CRM involvement is more an indicator of an advanced disease than of an incomplete resection.
