Few studies on how to diagnose pulmonary neuroendocrine tumors through morphometric analysis have been reported. In this study, we measured and analyzed the characteristic parameters of pulmonary neuroendocrine tumors using an image analyzer to aid in diagnosis.


Sixteen cases of typical carcinoid tumor, 5 cases of atypical carcinoid tumor, 15 cases of small cell carcinoma, and 51 cases of large cell neuroendocrine carcinoma were analyzed. Using an image analyzer, we measured the nuclear area, perimeter, and the major and minor axes.


The mean nuclear area was 0.318±0.101 µm2 in typical carcinoid tumors, 0.326±0.119 µm2 in atypical carcinoid tumors, 0.314±0.107 µm2 in small cell carcinomas, and 0.446±0.145 µm2 in large cell neuroendocrine carcinomas. The mean nuclear circumference was 2.268±0.600 µm in typical carcinoid tumors, 2.408±0.680 µm in atypical carcinoid tumors, 2.158±0.438 µm in small cell carcinomas, and 3.247±1.276 µm in large cell neuroendocrine carcinomas. All parameters were useful in distinguishing large cell neuroendocrine carcinoma from other tumors (p=0.001) and in particular, nuclear circumference was the most effective (p=0.001).


Pulmonary neuroendocrine tumors showed nuclear morphology differences by subtype. Therefore, evaluation of quantitative nuclear parameters improves the accuracy and reliability of diagnosis.

AbstractAbstract PDF
So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having predominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei. The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchiotoalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

AbstractAbstract PDF
Two cases of giant cell tumor of bone diagnosed by fine needle aspiration cytology are described. Case 1 was a 28-year -old male who had pain sense for one year at the right distal thigh. His radiologic finding revealed a destructive cortical lesion with soft tissue extension at medial side of epiphysis of the distal femur. Case 2 was a 21-year-old female complaining pain at left distal forearm for eight months and showed a well-demarcated expansile osteolytic lesion with multisepatation, and cortical destruction at epiphysis and metaphysis of the left distal radius on the X-ray. Fine needle aspiration of each lesion was performed. The aspirate of the case 1 reveated moderate cellularity, which was composed of scattered giant cells of osteoclastic type and small round to oval monotonous stromal cells in large areas. Giant cells were evenly distributed in single or small groups and had irregular but abundant cytoplasms with 10 to 20 nuclei in the center. The nuclei showed ovoid shape, fine granular chromatin, and a small but conspicuous nucleolus, Stromal cells were dispersed in isolated pattern or sometimes aggregated in clusters and showed the same nuclei as those of giant cells and scanty cytoplasms, Comparing to case 1, case 2 had a more translucent abundant cytoplasm in the giant cells and more spindled stromal cells, All two cases revealed neither nuclear atypism nor increased abnormal mitoses in both giant and stromal cells, suggesting no evidence of malignancy. Thereafter the lesions were treated with excision and curettage and histologically confirmed as giant cell tumors of the bone.
