  • A hepatic angiomyolipoma is a rare benign tumor mainly composed of blood vessels, smooth muscle cells and fat cells in varying proportion. Hepatic angiomyolipoma is often misdiagnosed as a hepatocellular carcinoma in preoperative imaging work-up. To date, there has been little published data describing PET findings of hepatic angiomyolipoma. We report one case of hepatic angiomyolipoma that showed a high acetate and relatively low FDG uptake on PET images.

  • Angiomyolipoma(AML) of the liver is a rare benign tumor; about 50 cases, almost solitary, have been reported. We present here a extremely rare case of multiple AML in the liver diagnosed by fine needle aspiration cytology(FNAC). Two large masses were found in a 51 year-old woman complaining of abdominal discomfort by computed tomography and several smaller masses are scattered in the liver. FNAC was performed, showing bundles of spindle shaped smooth muscle cells intermingled with mature fat cells. FNAC may be a valuable method for definitive diagnosis of hepatic AML. The diagnosis was further confirmed by histologic examination with immunohistochemical studies.

  • Leiomyomas are common in the myometrial layer of the uterus, though they are rarely found in other reproductive organs. Leiomyomas are benign, hormone-sensitive smooth muscle tumors. They develop during the reproductive years and regress after menopause. Preoperative diagnosis is difficult to make. We present a case of a 54-year-old woman with a vaginal wall tumor. The management in this case included surgical excision. Histologic examination definitively confirmed the diagnosis of a vaginal leiomyoma. We report the details of this case along with a brief review of the literature.

  • 혈관평활근종은 주로 팔다리에 발생하는 양성 종양으로 비강에 발생하는 경우는 매우 드물다. 저자들은 코중격에 발생한 혈관평활근종 1예를 경험하였기에 문헌 고찰과 함께 보고한다. 51세 여자가 잦은 코피를 주소로 내원하였다. 왼쪽 코중격에 경계가 좋은 종괴가 관찰되었다. 종괴에 대한 절제를 시행하였다. 절제된 종괴는 $0.7{\times}0.5{\times}0.4cm$ 크기였으며 회백색을 띠었다. 조직학적으로 종괴는 두꺼운 혈관벽을 가진 혈관과 민무늬근육세포의 증식으로 구성되어 있었다. 민무늬근육세포는 방추형으로 시가형태의 핵을 가졌으며 세포질은 호산성이었다.

  • Intravenous leiomyomatosis of the uterus is a rare tumor that presents with benign histological features. It is characterized by intravenous proliferation of smooth muscle cells originating from the uterus that sometimes extends to the inferior vena cava and the right heart. It may spread elsewhere, usually to the lung. The first case of intravenous leiomyomatosis was described in 1896 by Birsh-Hirshfeld, and only a few cases have been reported since then. Its pathogenesis and optimal treatment have not yet been established. We report a case of metastasizing leiomyomatosis found to have multiple nodular densities in both lower lung fields seven months after myomectomy. In another case the leiomyomatosis was confined to the pelvis after a laparoscopy assisted vaginal hysterectomy, the patient is alive without evidence of disease. Here we provide a detailed report of two cases of intravenous leiomyomatosis of the uterus with a brief review of the literature.

  • 정맥내 평활근종증은 자궁근육이나 혈관벽에서 발생한 평활근종이 정맥로를 통해 확장되어, 조직학적으로는 양성이나 임상적으로는 악성 경과를 취하는 매우 드문 질환이다. 종양은 대부분 정맥을 통로로 하공정맥, 우심방, 우심실, 심지어 폐동맥까지 확장되어 우심장의 폐쇄를 일으키면서 증상을 나타내는 것으로 되어 있으나, 매우 드물게 폐전이도 일으키는 것으로 보고되고 있다. 자궁에서 발생한 정맥내 평활근종이 우심실까지 확장되어 우심 폐쇄의 증상과 폐전이를 일으킨 53세의 여자 환자를 수술 치험하였기에 문헌고찰과 함께 보고한다.

  • Masses of the uterine cervix were detected from two dogs, being a 2-year-old female Yorkshire tarrier and a 12-year-old female Basset Hound. Grossly, the masses measuring 3.O$\times$3.O$\times$4.0 cm and 12.O$\times$l2.O$\times$10.07m were prominent, sharply circumscribed, fleshy tumors in the uterine cervix. Histologically, the masses consisted of smooth muscle cells interwoven in bundles, some of which were cut longitudinally (elongated nuclei) and others transversely. Tumor cell nuclei were ordinarily cigar shaped and had rounded blunt ends in the longitudinal plane. There were low mitotic figures without abnormal ones. From these results, these cases were diagnosed as leiomyoma of the uterine cervix. To our Knowledge, no similar tumors have been reported in the uterine cervix.

  • A 15-year-old intact female poodle dog was referred to a local animal clinic showing signs of dyspnea. A radiographic examination revealed multiple nodules in the lung. The following day, the animal died and a necropsy examination revealed multiple nodular masses of varying sizes in the lung. Microscopically, the tumor cells were composed of round to polygonal cells resembling adipocytes with little or no collagenous stroma. Most of the cells contained clear cytoplasmic vacuoles with the nucleus at the periphery while the other cells contained varying numbers of smaller vacuoles. The immunohisto-chemical evaluation yielded a positive reaction to S-100 and vimentin. Negative results were obtained for pancytokeratin, smooth muscle actin, desmin, epithelial membrane antigen and CD68. This case was diagnosed as a well-differentiated liposarcoma.

  • Esophageal duplication constitute about 10% of all the mediastinal tumor and relatively rare condition. We have experienced one case of esophageal duplication which was found 2 years previously by radiologic study of chest, as mediastinal mass, in 37 years old male. He had neither clinical manifestations nor physical findings leading to the surgical discovery of the duplication. During the last 2 years, the size k location of the mass were stationary in character. Operative therapy of complete excision performed without surgical complication. On microscopic study, the lining cell of inner wall of cyst. Noted pseudostratified ciliated columnar epithelium with smooth muscle.

  • Green tea contains several antioxidants including polyphenols of the catechin. which have been shown to act in vitro and in vivo as anti-inflammatory. anti-viral and anti-tumor drugs. Prostaglandins (PGs) are a family of intercellular and intracellular messengers derived from arachidonic acid(AA) by phospholipase(PL) and cyclooxygenase(COX). These mediators exert a wide range of effects on processes such as smooth muscle tone. vascular permeability, cellular proliferation. and inflammatory/immune function. (omitted)
