Xanthoma disseminatum (XD) is one of cutaneous nonhistiocytosis X, and characterized by multiple, widely distributed red, brown, yellowish papules and nodules that tend to coalesce. We present a case of XD with characteristic clinical findings and treated with the combination therapy of COz laser vaporization and high dose steroid.

Juvenile xanthogranuloma is a congenital or perinatal tumor, 1 to 2 cm in diameter, usually located on the head. The extracutaneous lesions can occur on the eye, the lung, the epicardium, the oral cavity or the testicles. Subcutaneous form of juvenile xanthogranuloma has been reported very rarely in the literature. We report a unique case of a subcutaneous juvenile xanthogranuloma that showed 4 × 4 cm sized plaque and located on the extremity of 9-year-old girl.

BACKGROUND: Linear lichen planus (LLP) and Lichen striatus (LS) are rare disorder that can be confused because they can share similar clinical and histopathologic features. OBJECTIVE: The purpose of this study was to evaluate the characteristic differences and common features between the two disorders histopathologically. METHODS: We reviewed the clinical records of patients who had been diagnosed as LLP or LS in our dermatology clinic during the 15-year period between 1985 and 1999. We classified twenty seven cases, which were differentiated from other possible linear dermatoses, into LLP and LS on the basis of clinical features, and then compared them histopathologically, and appreciated the characteristic differences or common features of the two disorders. RESULTS: In cases diagnosed as LLP clinically, epidermal changes were mainly composed of hyperkeratosis (78%), acanthosis (78%), basal degeneration (78%), granular layer thickening (67%) and saw-toothed appearance of rete ridges (44%). In dermis, colloid bodies (78%), band-like inflammatory cell infiltration with pigmentary incontinence (78%) were strik-,ting findings. In cases with clinical features of LS, parakeratosis (50%), dyskeratotic cells scattered in the epidermis (61%) and intercellular edema (39%) were noted in the epidermis. Dermal cellular deposits were focally band-like infiltration(89%), more frequently perivascular in-filtration (83%) and often involved deep dermis (50%), hair follicles (44%) and eccrine glands (22%) in contrast to LLP. CONCLUSION: This study presents a comparative histopathologic features of LLP and LS. Three cases of LLP with overlapping histopathologic features suggest the possibility that there may be an intermediate form between either end of a spectrum, LLP and LS.

PURPOSE: To evaluate the clinical outcome of retreatment after refractive surgery. METHODS: Retrospective analysis of 38 eyes of 24 patients who received retreatment surgery after refractive surgery from August 2008 to May 2013 was performed. Pre-initial surgery characteristics and the reason for retreatment were investigated, and preand post-retreatment uncorrected visual acuity, best corrected visual acuity, safety index, efficacy index, predictability, and postoperative complication were also investigated. RESULTS: Age at initial refractive surgery and retreatment were 28.50 +/- 7.29 years (17-49 years) and 31.21 +/- 6.49 years (21-49 years). Reasons for retreatment were myopic regression in 36 eyes (94.7%) and overcorrection in two eyes (5.3%). Methods of retreatment were laser subepithelial keratomileusis (LASEK) in 31 eyes (81.6%) and laser-assisted in situ keratomileusis (LASIK) in seven eyes (18.4%). Safety index values for all were above 1.0 and efficacy index values were 0.92, 0.93, and 0.95 in postoperative examination at 1 month, 3 months, and 6 months, respectively. No eye showed a decrease in best corrected visual acuity. One eye had transient hyperopia after retreatment, and two eyes had postoperative corneal opacity, but no eye experienced significant alteration in visual prognosis. CONCLUSIONS: Retreatment after refractive surgery was an efficient and safe clinical course in our clinic. No long-term complications were observed, and uncorrected visual acuity and refractive errors significantly improved after retreatment. In particular, LASEK can be considered as a safe and efficient retreatment modality without risk of keratectasia.

PURPOSE: To evaluation the accuracy of the IOL power calculation formulae measured by IOL Master(R) and applanation ultrasonography for the Tecnis ZCB00 IOL. METHODS: We performed a retrospective study of 170 eyes in 121 patients who underwent cataract surgery in our hospital with AMO Tecnis ZCB00 IOL.s. The SRK/T formula was used to predict the patient's implanted IOL power. Differences in the predicted refractive errors between IOL Master(R) and ultrasonography were analyzed and factors attributed to the differences were also analyzed. Three months after cataract surgery, mean numeric error and mean absolute error were analyzed. RESULTS: SRK/II and SRK/T formulas calculated using ultrasonography showed differences compared to the same formulas calculated using IOL Master(R), in which hyperopic shift was also demonstrated. No definite factor was attributed to the differences between the 2 methods. Although the 3 formulas of IOL Master(R) showed no significant difference in refractive errors, the SRK/T formula calculated using IOL Master(R) showed the least mean absolute and numeric errors. CONCLUSIONS: IOL Master(R) is considered more suitable when determining proper AMO Tecnis ZCB00 IOL power in cataract surgery. The hyperopic shift should be considered when calculating the IOL power using only ultrasonography.

Epithelioid angiosarcoma has recently been described as a variant of angiosarcoma, based on its pathologic feature which is characterized by epithelioid or histiocytoid morphology of the malignant tumor cells. We report a case of epithelioid angiosarcoma on the lower back of a 65-year-old man. The patient had several, variable-sized, pedunculated, fungating masses. On histopathologic examination, the tumor was chiefly composed of solid sheets of atypical epithelioid cells with prominent eosinophilic cytoplasm, a large vesicular nuclei, and occasional intracytoplasmic vacuoles. Primitive vascular spaces, and a cleft with malignant cells and proliferating vessels were also found in some areas. The reticulum stain and immunohistochemical stain using factor VII-related antigen and CD 31 were focally positive in the tumor. He was treated by wide surgical excision.

A 77-year old man presented with a fungating mass on the oral mucosa and lip, which had an irregular margin. An incisional biopsy of the mass revealed an invasive squamous cell carcinoma. PCR analysis detected HPV DNA in the biopsy specimen. The HPV type was determined as HPV-53 by direct cycle sequencing. This is the first report of HPV-53 in an oral malignant tumor.

Folliculosebaceous cystic hamartoma (FSCH) is a recently-recognized cutaneous hamar- toma composed of follicular, sebaceous and mesenchymal elements. We describe an unusual case of FSCH in a 61-year-old male, who had a relatively large, 3x2.5cm sized, smooth subcutaneous nodule on the occipital area of the scalp, an uncommon location for FSCH.

Prurigo nodularis is a distressing, chronic disease, which is considered to be very resistant to therapy. Treatment choice is quite limited. Among them, opiate antagonist and phototherapy have been used with satisfactory results. We report a case of treatment-resistant prurigo nodularis. Narrow band-UVB phototherapy was performed twice weekly for 3 months. Naltrexone 50mg was also taken daily before sleep. Pruritus was midly reduced after 1 week, and had almost completely disappeared after 3 months of treatment.
