Neurofibromatosis(NF) is a disorder characterized by its relative commonness, variability, and heterogeneity. It is usually expressed as a generalized form, but is rarely localized in a limited part of the body as a segmental form. In 1981, Riccardi classified NF into 8 types and a segmental form (type V) was defined by limitation of cafe-au-lait spots and/or neurofibroma on a given unilateral segment of the body. Recently we came across two cases of typical segmental neurofibromatosis. The First case was a 53-year-old woman with localized neurofibromatosis on the right T8,9 dermatome. The Second case was a 34-year-old man with localized neurofibromatosis on the right T5,6 dermatome. There were no cafe-au-lait spots, axillary frecklings, Lisch nodules or a family history in both cases. We report these rare cases with a literature review.

A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.

Accessory tragi are rare congenital malformations of the external ear. They are present from birth and appear as solitary or multiple papules located between the pretragal and sternoclavicular regions. Accessory tragi may be multiple but are almost always unilateral and rarely bilateral. We report two cases of bilateral accessory tragus and a typical case of unilat,eral accessory tragus manifesting as skin-colored papules on the preauricular area.

PURPOSE: The purpose of this study was to evaluate the utility of two-phase dynamic CT, early and equilibrium pahse, in the preoperative staging of rectal cancers. MATERIALS AND METHODS: We performed incremental dynamic CT after rectal infusion of water in 34 patients with pathologically proved rectal cancers. Two-phase dynamic CT findings were prospectively analyzed and correlated with surgical and histopathologic findings. A total of 150ml of nonionic contrast medium was intravenously administered with a power injector at a flow rate of 5ml/sec for 30 sec, and two-phase images were obtained at 30 sec(early phase) and 2 min (equilibrium phase) after bolus injection. Local tumor staging and regional lymph node were classified by TNM staging. RESULTS: All 34 rectal cancers showed a moderate to marked enhancement in the early phase and a homogeneous and prolonged enhancement of the entire lesion in the equilibrium phase. T-staging of primary tumors were 85.3%(29/34) in early phase and 70.6%(24/34) in equilibrium phase. The accuracy in determining the perirectal fat invasion of rectal cancer was 92%(23/25) in early phase, and 72%(18/25) in equilibrium phase. The sensitivity & specificity of the regional lymph node metastasis were 63.6% and 79.1% in early phase, and 54.5% and 65.2% in equilibrium phase, respectively. CONCLUSION: Early phase dynamic CT was more accurate for the preoperative staging of rectal cancer than that at equilibrium phase.

A 51-year-old Korean woman presented with a non-tender, well-demarcated, reddish, edematous patch on the right anterior chest where a previous mastectomy and radiation therapy had been performed. She had been diagnosed as having infiltrating ductal carcinoma of the right breast about 1 year ago. Histopathological findings of the skin lesions were consistent with inflammatory metastatic carcinoma of the breast. Inflammatory carcinoma or carcinoma erysipeloides is a well-established entity most frequently associated with carcinoma of the breast. It is characterized by dermal lymphatic invasion by malignancy and clinically should be distinguished from erysipelas or cellulitis. We describe a case of inflammatory metastatic carcinoma derived from an infiltrating ductal carcinoma of the breast which can be clinically confused with radiation dermatitis.

BACKGROUND: Pyogenic granuloma(PG) is a common lesion of the skin and mucous membranes. The gingival lesion developed during pregnancy termed epulis gravidarum is identical to PG. Many articles have appeared in the literature pertaining to this lesion and its putative relationship to the hormonal changes of pregnancy. Several clinical features such as association with oral contraceptive use and regression after delivery, suggest that PG may be a hormone-sensitive lesion. OBJECTIVE: Our aim was to determine whether estrogen or progesterone might affect the development of PG. METHODS: We performed immunohistochemical staining by using a monoclonal antibodies to estrogen receptor(ER) and progesterone receptor(PR) in 15 PG(pregnant women; 4 cases, non-pregnant women; 5 cases, and men; 6 cases). RESULTS: All 15 PGs were negative for ER. However, for PR, the degree of staining was different according to the patient group; pregnant women(3 cases[75%]: weak positive, 1 case[25%]: strong positive), non-pregnant women(3 cases[60%]: weak positive), and men(6 cases[100%]: negative). CONCLUSION: Our results suggest that estrogen or progesterone may not directly involve in the formation of these lesions. Further studies are needed to determine whether the other factors are related to the pathogenesis of PG.
