Island flaps have been widely used for the management of soft tissue defects in reconstructive surgery. The necrosis of the flap has been a catastrophe in clinical fields. It is well known that revascularization to the flap after ligation of its pedicle comes from the recipient bed and flap margins. The authors investigated the effects of the ischemic recipient bed on island flap survival after the ligation of its pedicle in the rats. One hundred and thirty inferior epigastric island flaps were divided into three groups (Group I, Group II, and Group III) according to the degree (0%,20%, and 60%) of interruption of contact of flap with the recipient bed, respectively. In Group I,the vascular pedicles were ligated before and on the 0, 2nd, 3rd, 4th and 5th days after flap elevation, and in Group II & III, the vascular pedicles were ligated on the 2nd, 3rd, 4th and 5th days after flap elevation. Flap survival was assessed on the 3rd day after pedicle ligation. Microangiographic studies were also performed on the 3rd day after pedicle ligation to study revascularization within the flap and the change of blood vessels around the flap margins. The results were as follows: 1. Flap survival was increased significantly in the flaps with pedicle ligation on the 4th and 5th postoperative days compared to those at the 2nd and 3rd postoperative days. 2. From the 3rd postoperative day, flap survival was not influenced significantly by the degree of limited bed contact and the date of pedicle ligation. 3. In spite of limited bed contact, the flap will likely survive with abundant revascularization from the flap margins. In conclusion, the flaps with limited bed contact were revascularized significantly from the flap margin by the 3rd postoperative day.

We report a case of familial benign chroinic pemphigus in a 47 year old man. We had tried various treatments but no effect had been noted with systemic steroids, tetracycline, cephalosporin, rifampin, dapsone, and local application with antibiotic ar..d eteroid ointment. Thus the patient was started on 50mg of etretinate(Tigason) daily and almost complete resolution of the skin lesions was noted two moths after treatment. He was maintained on 15mg of etretinate daily and follow up evaluations for six months revealed no recurrence and no exacerbation of the lesions.

Necrolytic migratory erythema is a rare, distinctive, necrotizing cutaneous eruption usually associated with glucagonoma, an alpha-cell tumor of the pancreas. Other clinical features include ane- mia, diabetes mellitus and weight loss. However, it also occurrs without the pancreatic glucagonoma. So this rare condition is called pseudoglucagonoma syndrome, and has been described in association with chronic hepatic diseases, malabsorption with villous atrophy, chronic pancreatitis, celiac sprue, hypoproteinemia and odontogenic infection. We report a case of pseudoglucagonoma syndrome induced by malnutrition without glucagonoma. A 28-year-old Korean female was referred to our department complaining of multiple erythematous, desquamative, crusted and erosive patches on the extremities, and diffuse scalp alopecia for 5 years. She also had perianal erosion, angular cheilitis without glossitis, amenorrhea, axillary and pubic hair loss, and weight loss. Six years previously she had had Whipples operation for a pancreatic solid and papillary neoplasm. The laboratory data showed hypoalbuminemia, essential fatty acid deficiency, diabetes mellitus and slightly high levels of zinc and glucagon. A skin biopsy showed irregular acanthosis, epidermal edema and pallor, dyskeratosis, areas of superficial epidermal necrosis and vascular dilatation of the papillary dermis. The patient improved dramatically after intravenous hyperalimentation and oral intake of mediurn chain triglyceride. For 2.5 years she has taken medium-chain triglycerides without any other treatment, and no side effects on recurrence has been observed.

Letterer-Siwe disease is one of Langerhans cell histiocytosis, with Hand-Schuller-Christian disease and eosinophilic granuloma, characterized by proliferation of Langevha is cell. The clinical course of Letterer-Siwe disease is acute fulmunant of casionally fatal, involving skin and many other internal organs, such as the lymph node, liver, spleen, ung and bone. We present 3 cases of Letterer-Siwe disease with characteristic cutaneous findings and revealed Langerhans granules by imrriunohistochemical stain and electronmicrc scopic examination. All patients died in spite of combined chernotherapy.

A 51-year-old female had disseminated, symmetrically distributed, brownish black pigmentation and papillary hypertrophy on the intertriginous and flexural areas for 6 months, and gastric adenocarcinoma was confirmed during the evaluation of internal malignancy, The cutaneous finding of acanthosis nigricans was a significant cutaneous marker of internal malignancy in this case.

Great difficulty may be encountered in the differentiation of basal cell carcinoma from trichoepithelioma snd, in some cases, it may even be irnpossible. Immunohistochemical methods using peanut agglutinin(PNA) which is glycoprotein of non-immune origin selectively binding to galactose-N-acetyl-galactosa-mine are increasingly used in dermatopathology to improve the diagnosis and differential diagnosis. Using PNA, anti-PNA antibody, and peroxidase antiperoxi-dase(PAP) technique, normal skin specimens, basal cell carcinomas, trichoepitheliiomas, and a variety of different skin tumors were studied, and different PNA Ibinding sites between basal cell carcinomas and trichoepitheliomas were observed. The results were as follows : l. In normal skin, except the basement membrane, epidermis and hair follicle epithelium showed a cell membrane staining of PNA, which stained weakly in the Ibssal cell layer. Sebaceous glands revealed membranous and cytoplasmic staining of PNA, but sweat ducts and duct coi1s were mostly negative. 2. 34 of 36(94.4%) basal cell carcinoma sections demonstrated peritumorous PNA-positive bands, and none of 5 trichoepithelioma sections showed peritumorous PNA-binding. 3. Peritumorous PNA-positive bands were strongly positive in solid and keratotic basal cell carcinomas, but decreased or absent in the vicinity of the ulceration or the dense inflammatory infiltration. 4. None of the other skin tumors(squamous cell carcinoms, keratoscanthoma, Bowens disesse and actinic keratosis} showed a periturnorous PNA-positive band. Therefore, we believe that the PNA staining on paraffin-embedded sections using PAP technique can be a useful probe for the differentiation of basal cell carcinoma from trichoepithelioma.

Acute appendicitis is the most common operative disease in general surgery, but it is not also rate disease to see in other clinical department such as Internal Medicine and Obstetric and Gynecology, because it reqnires to differenciate from many other diseases which have similar symptoms. Expecially, because the clipical aymptoms of acute appendicitis are not typieal in children, elderly, and women, it is hard to be diagnosed as acute appendicitis and it is often misdiagnosed as other disease. We performed colonoscopy due to be interpretated aa one of the colon diseases rather than acute appendicitis. But in colonoscopic findings, there were hyperemie and edematous change on the appendiceal orifice of cecum(cherry or acorn shape). So we report 5 cases of acute appendicitis diagnosed br colonoscopy.

Korean Journal of Dermatology 1997;35(1):169-173
It has been generally assum d that eccrine poroma arises from acrosyringium, the epidermal sweat duct unit. Eccrine poroma mainly involves the non hairy surfaces of the skin, but it has also been found on hair-bearing areas. One of the characteristics of this structure is absence of melanocytes and melanin granules arnong its cells. However a complete absence of melanocytes and melanin granules in eccrine poroma is not invariable and a few reports of such an occurrence have been presented. The authors report herein a case of unusual and rare eccrine poroma. The eccrine poroma had melanin pigment and melanocytes, was pedunculated and occurred on the parietal scalp which was the unusual site of involvement. The eccrine poroma was also combined with a pedunculated congenital melanocytic nevus on the supraauricular scalp.
