1.Mucous Gland Adenoma of the Bronchus: A case report.
Korean Journal of Pathology 1985;19(3):368-373
Mucous gland adenoma, one type of bronchial adenoma, is first introduced by Rosenblum and Klein2) in 1935 and very rare. Only twenty-one cases had been reported in english literature. This tumor must be differentiated from other types of bronchial adenoma because of completely benign clinical course. A case of mucous gland adenoma is presented which showed marked secondary calcification.

We describe cytologic findings of two cases of pilomatrixoma which had been cytologically misdiagnosed as suspicious malignant and malignant lesions in 35 year-old and 22 year-old females who presented a palpable neck mass. The cytologic smears showed many basaloid cells with a high nuclear-cytoplasmic ratio, nuclear hyperchromatism and prominent nucleoli, keratinized squamous cells with pyknotic nuclei, foreign body giant cells, and chronic inflammatory cells in necrotic background. Retrospective view of this aspiration smear revealed that these findings were characteristic features of pilomatrixoma, and the evenly distributed chromatin pattern as well as the lack of nuclear pleomorphism were considered to be the differential points from malignant neoplasm. Pilomatrixoma is a benign neoplasm which should be included in differential diagnosis if the fine needle aspiration cytologic smear of a neck mass or subcutaneous mass of any site showed these features.

The spotted grouped pigmented nevi is one of special forms of non-giant congenital melanocytic nevi. Histologically the nevus cells tend to proliferate around the skin appendages. We have experienced a case of spotted ground pigmented nevi in a 11 year old girl who had a pigmented plaque consisting of grouped brown black regularly distributed papules on the left inguinal region since birth. Histology revealed intradermal nevus. The skin appendages, especially the hair follicles and eccrine sweet ducts were enveloped by the neuvs cells. Electron microscopic study revealed that this nevus cells were mostly of type B cells. We would like to consider that the spotted grouped nevi are closely related pathogenically with the skin appendages.

Peutz-Jeghers syndrome is an autosomal dominant disease characterized by gastrointestinal ployposis and mucocutaneous melanin pigmentation involving the lip, oral mucosa, digits, palms and soles. The polyps are almost hamartomatous. The relationship of gastrointestinal carcinoma and the Peutz-Jeghers syndrome has been discussed for many years. The question is unsettled whether gastrointestinal carcinoma arise in hamartomatous polyps itself. Recently, there are a few reports that adenomatous and carcinomatous changes were superimposed upon the background of the hamartoma. Occasionally epithelial misplacement of the epithelium is found in the small intestinal polyps. Since the epithelial misplacement may involve submucosa, muscularis propria and serosa, a difficulty of histopathologic differential diagnosis between the epithelial misplacement and invasive adenocarcinoma cause overdiagnosis of cancer in the gastrointestinal polyps of Peutz-Jeghers syndrome. We present a case of Peutz-Jeghers syndrome of 39-year-old woman with multiple gastrointestinal polyps, two of which showed extensive epithelial misplacement even into the pancreas and another one at the colon showed carcinomatous change at the tip portion. Areas of hamartoma, adenoma and in situ carcinoma were noted in this colonic hamartomatous polyp. This case support that adenoma and carcinomatous changes may evolve directly within a hamartomaous polyp itself.

9.Recent Update of Pathology of the Pancreatic Neuroendocrine Tumor.
Korean Journal of Medicine 2011;80(4):371-377
Pancreas is an endocrine organ as well as an exocrine one. The pancreatic neuroendocrine tumor (PNET) is an epithelial tumor with features of endocrine differentiation. Its incidence is progressively increasing now. Because the prognosis of PNET is much better than that of ductal adenocarcinoma, the precise diagnosis and proper treatment is more important than ever. Recently World Health Organization (WHO) and American Joint Committee on Cancer (AJCC) published the new WHO 2010 classification and the unified staging system of the PNET unlike the other gastrointestinal tract. Here, recent update of pathology of PNET will be discussed with their basic morphologic characteristics and essential points in the pathology report.

BACKGROUND: Recently, clinical use of fresh frozen plasma(FFP) has increased in all blood transfusion activity. But inappropriate uses of FFP may be serious problem due to adverse transfusion reactions, viral transmission, and economic aspects. The aim of this study is to justify clinical indication of FFP by receiving the inappropriate use of them. METHODS: Analyzing hospital records of 115 patients transfused with FFP at Kyung Hee Medical Center from January to April 1998, retrospectively, we investigated the purpose of transfusions, the volume of transfused FFP, and the results of pre- and post-coagulation tests. RESULTS: The most common purpose of transfusions of FFP was plasma volume replacement after surgical operation. Coagulation tests of pre- and post-transfusion were performed 85% and 47%, respectively. Fifty-seven patients(88%) transfused FFP have shown normal results in pre-coagulation tests, and the volume replacement with FFP was done inadequately in 62 cases(54%). CONCLUSION: We conclude that, in order to eliminate side effects due to inappropriate use of FFP, and protect patients, it is necessary to make guidelines of FFP transfusion, educate hospital staffs regularly, and perform pre- and post-coagulation tests routinely for the patients who need FFP transfusion.
