We report here a case of a gastrointestinal stromal tumor (GIST) in the stomach that was diagnosed by endoscopic ultrasound-guided fine needle aspiration cytology (EUS-FNA). A 67 year old male patient underwent regular check-ups for five years due to the presence of a submucosal tumor that was found in the fundus of the stomach incidentally. EUS-FNA was performed to evaluate the tumor, which had increased in size from 1 cm to 2.8cm. A cytologic smear revealed cohesive sheets or clusters of spindle cells with elongated nuclei. Immunohistochemical staining revealed a strong positive reaction for c-kit and CD34, without any reaction for smooth muscle actin and Ki-67. Therefore, a diagnosis of GIST was made.

Parathyroid tumors may be difficult to distinguish from thyroid follicular lesions, especially when a tumor is nonfunctioning. We report here two cases of asymptomatic parathyroid carcinoma preoperatively misdiagnosed as thyroid follicular lesions, and one case of parathyroid adenoma showing hyperparathyroidism, and review the cytologic features favoring the diagnosis of parathyroid neoplasm. The cytologic findings that are characterized by clean background, monomorphic small cells, cohesive three-dimensional papillary clusters, small tight clusters with scattered naked nuclei, and well-defined clear cytoplasm favor a diagnosis for the parathyroid lesions. Cytologic findings such as macrofollicular structure, presence of colloid and macrophages, and presence of perivacuolar cytoplasmic granules on May-Grunwald-Giemsa stain support a diagnosis of a thyroid follicular lesion. The cytomorphology of parathyroid tumors is so variable that the distinction from a thyroid lesion cannot be based on the presence or absence of a single feature only but on the cytologic features as a whole.

Merkel cell carcinoma (MCC) is a rare primary cutaneous neuroendocrine carcinoma which commonly presents as a skin nodule, and can develop into regional lymph node metastases, as well as spread systematically. Here, we describe the cytological features of a touch imprint of MCC that arose on the face of a 62-year-old female. This touch imprint was acquired from an incisional biopsy specimen which had been submitted for frozen section. The touch preparation produced a highly cellular imprint of loosely cohesive groups of small- to medium-sized malignant cells exhibiting uniform round to oval nuclei, delicate nuclear membranes, fine chromatin, small nucleoli, and scanty cytoplasm, with occasional paranuclear button-like inclusions. We applied cytokeratin 20 to the touch imprint for immunochemistry, allowing us to visualize the tumor cells with paranuclear dot-like positivity. Both the cytological and immunocytological features were quite distinct.

Fibromatosis colli is a benign fibrous tissue proliferation of sternocleidomastoid muscle, which is usually observed during the first month of life, often associated with congenital torticollis. It should be differentiated from other neck masses in infants because the usual initial treatment of fibromatosis celli is conservative management and invasive therapy should be avoided. Fine needle aspiration cytology provides an excellent minimally invasive diagnostic way for evaluation of infantile neck masses. We describe three cases of fibromatosis colli diagnosed by fine needle aspiration cytology. All of them were younger than one month and presented as a neck mass. Clinical impressions were malignant tumors in two cases and fibromatosis colli in one case. Fine needle aspiration cytology revealed benign and mature fibroblasts and atrophic striated muscle fibers. The cytologic diagnosis was fibromatosis colli or benign fibous lesion.

Background : Anti-reflux procedures treat gastroesophageal reflux (GER) disease. It is known that gastroesophageal reflux is likelyrelated to the increased incidence of chronic rejection in lung transplantation recipients. Because experimental animal studies areto verify this, we have tried to make an animal model of GER in a rat. Material and Methods : Using the SD rats weighing 250-300 g, we surgically induced gastroesophageal reflux and measured the gastrostomy time under anesthesia. Of three groups, Group I was the control, Group II had lower esophageal and anterior myotomy, and Group III had lower esophageal and anterior myotomy plusdiaphragmatic crural myotomy.The animals were scarified, and lung biopsies and histological examinations were performed 1 week, 2 weeks, 4 weeks, 8 weeks and 3 months after gastroesophageal reflux surgery. Results : Baseline animals (n=5) had no GER after charcoal instillation through a gastrostomy tube in Group I. Charcoal-laden macrophages were observed in GroupsII and III. To determine evidence of GER evidence, charcoal was instillated through the gastrostomy tube in group III. In contrast, Group II demonstrated severe neurophil infiltration in the bronchioles and alveolar walls after procedure. After 12 weeks, we observed the disappearance of neurophil, lymphocyte and histiocyte infiltration, and also occasional focal bronchopneumonia and bronchitis. Group III demonstrated neurophil and basophil infiltration in the bronchioles and alveolar walls which was more severe than that in Group II. Interstitial fibrotic changes were observed in Group III.Conclusion : The purpose of our gastroesophageal reflux model was to find evidence of aspiration. There was more evidence of aspiration in Group II than in either of theother two groups.

에크린 한공암종은 흔하지 않으며, 전이성 에크린 한공암종은 매우 드문 암이다. 에크린 한공암종은 표피내 한관에서 기원하는 피부 부속기 악성 종양으로, 대부분 에크린 한공암종은 항암치료와 방사선치료에 효과가 없으며, 따라서 유일한 치료방법은 전이되기 전에 국소 및 광범위 절제술을 시행하여야 한다. 본 환자는 두피에 발생한 에크린 한공암종이 점점 진행하여 피부, 림프절, 폐 등으로 전이하였고, 다수의 광범위 절제술에 이어 항암치료와 방사선치료를 받았지만, 결국 폐전이가 악화되어 사망하였다. 본 저자들은 항암치료와 방사선치료에 불응한 에크린 한공암종 1예를 치료에 대한 문헌고찰과 더불어 보고하는 바이다.

Objective : To identify key cytologic features for diagnosis of adenocarcinoma and morphologic differentiation from reactive/reparative respiratory epithelium. Study Design : The cytomorphologic features of 145 pulmonary cytology specimens (sputum and bronchial washing), which included 117 histologically proven adenocarcinomas and 28 non-neoplastic lesions, cytologically diagnosed as atypia and suspicious for malignancy (adenocarcinoma) were reviewed retrospectively. We analyzed 11 morphologic criteria in pulmonary cytologic specimens. Results: Over 110 of 117 cases of adenocarcinomas revealed nuclear membrane irregularities, non-cohesive cells, single atypical cells, moderate to markedly enlarged nuclei and an increased nuclear/cytoplasmic (N/C) ratio. Chromatin clearing, chromatin heterogeneity and hyperchromasia were seen in 102, 99 and 97 cases, respectively. All 28 cases involving non-neoplastic lesions revealed hyperplastic reactive pneumocytes, hyperplastic reactive bronchial epithelium, or degenerating macrophages. The non-neoplastic lesions revealed a small number of atypical cell clusters and paucity or absence of atypical single cells. Conclusion : The most important morphologic features for diagnosis of adenocarcinoma are nuclear membrane irregularities, non-cohesive cells, single atypical cell, moderate to markedly enlarged nuclei and increased N/C ratio. Chromatin clearing, chromatin heterogeneity and hyperchromasia were also helpful features, while pleomorphism and prominent nucleoli were less valuable.

T-cell prolymphocytic leukemia (T-PLL) is a rare, mature T-cell lymphoproliferative disorder with a post-thymic mature T-cell phenotype. The disease is characterized by rapidly rising lymphocytosis, lym-phadenopathy, and splenomegaly. The clinical course is usually aggressive and progresses with frequent skin lesions and serous effusions. In 25% of cases, leukemic cells are small and tumor cells may not have a discrete nucleolus under light microscopy. Although the presence of characteristic cytoplasmic protrusions or blebs in tumor cells is a common morphologic finding in the peripheral blood film irrespective of the nuclear features, small cell variants lacking the typical nuclear features can cause diagnostic problems in clinical cytology. Furthermore, the small leukemic cells can share some cytologic findings with lymphocyte-rich serous effusions caused by non-neoplastic reactive lymphocytosis as well as other small lymphocytic lymphoproliferative disorders. Here, we describe the cytological findings of ascitic fluid complicated by small cell variant T-PLL in a 54-year-old man, the cytology of which was initially interpreted as small lymphocytic malignancy such as small lymphocytic lymphoma/chronic lymphocytic leukemia.
