Abstract
PDF Background 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.
Methods 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.
Results 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).
Conclusions Pulmonary neuroendocrine tumors showed nuclear morphology differences by subtype. Therefore, evaluation of quantitative nuclear parameters improves the accuracy and reliability of diagnosis.

Abstract
PDF
- 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.

Abstract
PDF
- Large cell neuroendocrine carcinoma (LCNEC) of the uterine cervix is a rare and aggressive malignancy. We report a case of uterine cervical LCNEC concurrent with high grade squamous intraepithelial neoplasia (HG-SIN). The LCNEC expressed chromogranin A and thyroid transcription factor 1 (TTF1). The HG-SIN was negative for these markers. Human papillomavirus (HPV) type 18 was positive in LCNEC whereas both type 16 and 18 were positive in HG-SIN by nested polymerase chain reaction. This case showed TTF1 positivity nonetheless diagnosed as a primary uterine cervical LCNEC confirmed by the detection of HPV genome within the tumor. It is critical to recognize LCNEC of the uterine cervix even in the small biopsy specimen because it is a distinctive clinicopathological entity with highly aggressive behavior and unfavorable outcome.
