A 51-year-old man had multiple nonspecific subcutaneous nodules and small red hemorrhagic papules on his trunk. Histopathologically, the subcutaneous nodules were shown to be lobular capillary hemangiomas with edematous stroma throughout the entire subcutaneous fat. Multiple subcutaneous granuloma pyogenicum is a rare variant of granuloma pyogenicum. The addition of cherry angioma in the same patient also makes it a very unusual case.

BACKGROUND: Arterial blood gas analysis are highly susceptible to preanalytic error due to improper method of obtaining or handling the blood sample before analysis. The error in measurement of blood gas analysis are loss of CO2 by exposure to atmospheric air, effect of anticoagulant itself, temperature difference between the experimental subject and the measuring electrode and metabolic change which occur between blood sampling and measurement. METHOD: To study the effect of the delay in estimation of blood gas and drawn blood on values of blood gas partial pressure and pH. Blood sample were divided into 2 groups according to the method of storage, group I stored at 24~25degrees C(room temperature) under anaerobic condition. ;group II stored at 0~4degrees C(refrigerator) under anaerobic condition. The samples were analyzed by time interval through 180 minutes in each group. RESULTS: The result were as follows: 1) PaO2 decreased significantly after 10 mins in group I, whereas it decreased significantly after 20 mins in group II. 2) PaO2 increased significantly after 20 mins in group I, whereas it increased significantly after 120 mins in group II. 3) pH decreased significantly after 60 mins in group I, whereas it decreased significantly after 120 mins in group II. 4) No significant changes of bicarbonate and SaO2 were noted in each group CONCLUSION: From above results, it would be advisable to analyze the sample in a short period of time or to store in a refrigerator when the measuring will be delayed. So we highly recommend that blood gas analysis should be performed as soon as possible after sampling, especially within 10 minutes.

Generalized pustular psoriasis is a severe form of paoriasis and is frequently associated with arthritis and nail deformity. We present a case of generalized pustular psoriasis in a 40 year-old man, with nail change, arthritis of both knee and ankle joints, spondylitis, and glomerulonephritis. We found a positive results of HLA A-9, B-27 in this patient. Skin lesions, arthralgia and hematuria improved marked1y by plasmapheresis and application of topical corticostertoid.

BACKGROUND: The immunohistochemical detection of endothelial differentiation in skin tumors has been hindered by the relative paucity of reliable markers that are applicable to rou- tinely-processed specimens, which are both specific and sensitive as well. OBJECTIVE: This study was designed to evaluate the utility of CD31 and CD34, newly introduced vascular markers, in the immunohistochemical differentiation of vascular neoplasms from other mesenchymal tumors and to compare their sensitivity and specificity with factor VII-related antigen (FVIIIRA). METHODS: Paraffin-embedded specimens of 26 cases of benign and malignant vascular tumors and 25 cases of non-vascular mesenchymal neoplasms of the skin and subcutis were investigated for CD31, CD34, and FVIIIRA expression using immunohistochemical methods. RESULTS: CD31-immunoreactivity was observed in all of the 26 vascular lesions. CD34 and FVlllRA were labelled in 23 cases and 16 cases of vascular tumors, respectively. All of the 25 non-vascular mesenchymal tumors were negative for CD31 and FVIIIRA. In contrast, positive reactivity for CD34 was seen in 14 cases, among which dermatofibrosarcoma protuberans(2/2), neurofibroma(8/8), neuriilemmoma(2/2), and leiomyoma(2/3) were included. CONCLUSION: Our results indicate that CD31 is a more sensitive and specific vascular marker than CD34 and FVIIIRA. A small panel composed of these three antibodies will constitute a comprehensive and reliable method for identifying tumors of vascular origin.

Yellow nail syndrome is characterized by yellow discoloration of nails, chrnnic lymphedema and respiratory dieorders such as chronic bronehitis, bronchiectasis, pleural effusion and chronic sinusitis. Other changes of nail in this syndrome are the exaggerated lateral curvature and disappearance of lunula and cuticle. These nail changes are caused by greatly slow nail growth than in normal due to the defective lymphatic drainage. We report a case of yellow nail syndrome in a 55 year-old woman who has pulmanary edema, congestive heart failure for 3 years, and yellow naiIs of all fingers and toes for 1 year.

A case of foregut cyst communicated with esophagus and lined by bronchial mucosa is reviewed and its embryologic base of maldevelopment it discussed. It is not always easy to distinguish between digestive and respiratory cyst in mediastinum. There is whole range of intermediate between a cyst with ciliated and one with squamous or columnar mucosa. Origin of this dysembryoplasia is difficult to determine when on consider that the esophagus is covered with ciliated epithelium until the eleventh week of fetal life and that ciliated growth are found on its wall until the sixth month of the fetal life. And we concluded, general agreement is that cysts which have gastric epithelium in whole or in part, represent a distinct type and should be classified as (gastro) enteric cyst, mediastinal cyst containing cartilage were considered definitely as respiratory (bronchial or bronchogenic) cyst.

Ossifying fibroma is a benign tumor which arises typically within the jaw bone and rarely affect the long bone. The usual affected site in the long bone is tibia and fibula. Ossifying fibroma has a moderate tendency to progress during childhood and ceases to progress after puberty. So, surgery should be delayed as long as possible. But if the lesion is wide, which may cause pathologic fracture or severe deformity, it would be necessary to resect the lesion and restore the alignment. We have experienced 10 cases of ossifying fibroma which were treated at Department of Orthopaedic Surgery, Yonsei University College of Medicine, from Jan. 1984 to Nov. 1992. Results were.as follows: l. Among 10 cases, female was 5 cases and male was 5 cases. Age at operation was 9 years 1 month in average ranging from 1 year 7 months to 18 years 6 months. 2. The lesion site was 9 cases in the tibia, 1 case in the fibula. 3. Attended type of treatment was 3 cases of bone biopsy and observation, 1 case of curettage and bone graft, 1 case of curettage, external fixation with Ilizarov apparatus and internal transportation, 1 case of resection with curettage and free vascularized fibular graft, and 4 cases of wide resection and free vascularized fibula graft. 4. Second operation was needed in 2 cases due to recurrence which were performed incomplete wide resection. In conclusion, continuous observation is needed until puberty when the lesion ceases to progress in ossifying fibroma but radical surgery like wide resection and free vascularized fibula transfer is needed if there is a risk of pathologic fracture or severe bowing deformity due to its large size.

Fibrolipoma is an uncommon variant of lipomas which shows a distinct pathologic findings with both component of mature adipose cells and broad bands of dense fibrous connective tissue. A 30-year-old woman developed an 5×7cm sized, indurated, ill-defined, subcutaneous mass on the right axilla. Microscopically, the tumor contained broad bands of dense connective tissue with mature adipose tissue scattered throughout the mass, but it did not show encapsulation. The lesion was excised and she showed no evidence of recurrence after 6 months of follow-up.
