Pyogenic granuloma (PG) and port-wine stain (PWS) are vascular lesions that rarely occur in association. While PWSs are congenital capillary vascular malformations, PGs are acquired benign vascular proliferations. Although the pathogenesis of PG is unknown, many authors feel that they represent reactive hyperplasias, especially as they are often seen in response to trauma. We report the multiple pyogenic granulomas developed in a port-wine stain following Nd-YAG laser therapy.

Two cases of epidermal nevi treated with systemic etretinate are presented. Case 1, a 21-year-old female, had been suffered from brownish verrucous papules and plaques on the left inguinal area, thigh, lower leg and dorsum of the foot since her first month of life; and case 2, a 4-year-old boy, had been suffered from brownish verrucous papular plaques on the left chest, axilla and back since birth. In both cases, there was no family history of similar disease. On histopathological examination, case 1 showed the findings of epidermolytic. hyperkeratosis but case 2 did not, with the exception of clumping of keratohyaline granules. In the treatment with systemic etretinate, we observed marked clinical improvement in case 1, but not in case 2. Any particular side effects of etretinate were not observed during treatment. We consider that etretinate therapy is useful in treating epidermal nevus with epidermolytic hyperkeratosis histopathologically.

PURPOSE: To investigate the preoperative characteristics and postoperative change of the higher-order wavefront aberrations (HOAs) in myopic photorefractive keratectomy (PRK). METHODS: Standard PRK was performed in 39 eyes (spherical equivalent -4.71+/-1.56D) using the VISX(R) STAR S4(TM) excimer laser system. Wavefront analysis was performed preoperatively and 6 months postoperatively using the VISX(R) WaveScan(TM) aberrometer. Statistical analysis was performed to assess the preoperative characteristics of the HOAs and the PRK-induced aberrations. RESULTS: The preoperative root mean square (RMS) value of the total HOAs was 0.291 micrometer: coma 0.159 micrometer, trefoil 0.157 micrometer, spherical aberration 0.093 micrometer. Among the 3 HOAs, only the spherical aberration showed moderate magnitude negative correlation with the spherical equivalent (p=0.012) and sphere (p=0.005). The magnitude of all of the HOAs, except trefoil, were significantly increased at postoperative 6 months: total HOAs 183% (0.533 micrometer, p<0.001), spherical aberration 341% (0.317 micrometer, p<0.001), coma 185% (0.294 micrometer, p<0.001), trefoil 104% (0.163 micrometer, p=0.681). In the postoperative correlation analysis, only the PRK-induced spherical aberration showed the increase of magnitude with increasing preoperative spherical equivalent (p=0.036) and sphere (p=0.019). CONCLUSIONS: The HOAs, especially spherical aberration and coma, were increased after PRK. Among the 3 HOAs, the spherical aberration showed the greatest increase of magnitude and percent change; it also showed a positive correlation with increasing preoperative spherical equivalent and sphere. Further software improvements in the wavefront-guided surface ablations need to have a diminution of PRK-induced spherical aberration.

CT findings of 19 kidneys in 12 patients with renal and perirenal non-Hodgkin's lymphoma were retrospectively reviewed to determine distinguishing characteristic and specific findings. CT manifestation of the renal and perirenal lymphoma included multiple nodules in five kidneys(26.3%), trans-capsular infiltration in three kidneys(15.8%). trans-sinus infiltration in nine kidneys(47.4%) and diffuse infiltration in two kidneys(10.5%0. Perirenal changes were thickening of the renal fascia in ten kidneys(52.6%) and crescentic lesion of low attenuation in the subcapsular area in five kidney(26.3%). Retroperitoneal lymphadenopathy was evident in eleven patient(57.9%). Renal calyceal dilatation without renal pelvic dilatation(selective calcelal dilatation) was noted in three kidneys. Familiarity with these CT findings of renal and perirenal lymphoma may be helpful in the diagnosis and management of patient with non-Hodgkin's lymphoma.

We experienced a 57-year-old male patient who have had multiple coin sized, erythematous, psinful, indurated ulcerations with purulent discharge on the right calf area since 10 years before. Previously he received injections of paraffin in the lesion site for correcting the thinning of right calf due to complication of pyoderma. Histopathologic examination showed "Swiss cheese" appearance of parsffinoma. Good result was obtained after treatment with surgical excision and split thickness skin graft.

PURPOSE: Superior sulcus deformity is the main cosmetic problem in anophthalmic patients. Many methods of correcting enophthalmos have been reported, especially in patients with orbital wall fracture. The purpose of this study is to review the long term results of effectiveness in superior sulcus deformity correction by subperiosteal Medpor (R) sheet implantation in anophthalmic patients. METHODS: Subperiosteal Medpor (R) sheets were used in 11 eyes of 11 anophthalmic patients. To estimate the effectiveness, photographs were taken and exophthalmometric value with their own prosthesis using Hertel exophthalmometer was measured in all patients before and after surgery. RESULTS: The overall cosmetic results in superior sulcus deformity were 'excellent' in 3 (27.3%), 'good' in 6 (54.5%), 'fair' in 2 (18.2%). The overall results in enophthalmos were 'excellent' in 3 (27.2%), 'markedly improved' in 4 (36.4%), 'slightly improved' in 4 (36.4%). Most patients had a marked increase in orbital volume, except two patients. They received irradiation treatment in early childhood so showed unsatisfactory results in both superior sulcus deformity and enophthalmos. CONCLUSIONS: Subperiosteal Medpor (R) sheet implantation is considered to be a reliable and safe procedure without serious complication and with an excellent cosmetic results.

Tattooing has been performed the for cosmetic purpose by many beautician in the beauty parlors without having been any medicalknowledge. This has resulted in various serious complications. One patient is a 56-year-old female, who had been developed pruritic erythernstous indurated plaques on the tattooing sites about 3 months after getting tattoo. Skin biopsy findings revealed granulomatous inflamrnation and patch test showed positive reaction to potsssiurn dichromate. The other patient is a 55-year-old female, who had been developed erythematous papules on the both lips of tattooing sites about 1 year after getting tattoo. Skin biopsy findings revealed lichenoid resction. Patch test showed positive reactions to reornycin eulfate and nickel sulfate. Patch test of as is revealed positive reactions to red color.

PURPOSE: The prognosis of stage IV stomach cancer patients is very poor and the effectiveness of radical surgery including extended lymphadenectomy and combined resection in these patients is still controversial. The purposes of this retrospective study were to identify the prognostic factors and to evaluate the effectiveness of extended lymphadenectomy and combined resection in stage IV stomach cancer paients. MATERIALS AND METHODS: Of 585 patients who were operated for stomach cancer at the NMC from Jan. 1987 to Oct. 1993, 154 patients of stage IV stomach cancer (121 patients who had distant metastasis and 33 patients who had not) were identified. We analyzed data of these 154 patients to find the characteristic clinicopathological features, the prognostic factors and the proper extent of surgical treatment. RESULTS: Comparing with stage I, II and III groups, larger tumor size, higher proportions of Borrmann type IV and undifferentiated carcinoma and higher rates of lymph node metastasis and combined resection were noticed in stage IV stomach cancer group. In combined resection, pancreas tail was mainly resected due to tumor invasion but spleen was mainly resected for the completeness of lymph node dissection. In multivariate analyses, peritoneal metastasis and postoperative residual tumor were independent prognostic factors. The overall 5-year survival rate was 14.6%. Stage IV stomach cancer patients without distant metastasis had better 5-year survival rate than that of those who had distant metastasis (34.3% vs 7.9%, p=0.00001). CONCLUSIONS: Radical procedures including extended lymphadenectomy and combined resection of the invaded organs should be considered in the stage IV stomach cancer patients without distant metastasis.
