Giant cell tumor of tendon sheath is the second most common tumor involving the hands. It usually presents as a slowly growing, lobulated, painless subcutaneous mass. Histologically, the tumor is composed, in variable proportion, of histiocytoid mononuclear cells, multinucleated giant cells, xanthoma cells, and collagenized stroma. Although numerous characteristic multinucleated giant cells are usually noticeable in the tumor, they may be difficult to find, or be entirely absent. We present two cases of giant cell tumor of tendon sheath in which giant cells was not and rarely found respectively.

4.A Case of Proliferating epidermoid cyst.

Proliferating cutaneous epithelial cyst is classified into two subtypes, proliferating trichilemmal cyst and proliferating epidermoid cyst, depending on the mode of keratinization or the origin of the tumors. Proliferating epidermoid cyst is a subepidermal cystic tumor showing, at least in focal areas, a cystic wall lined by epithelium typically seen in epidermoid cyst. We report a case of proliferating epidermoid cyst in a 58-year old man who had a 3x4 cm sized egg shaped cystic tumor on the occipital area of the scalp. Histopathologic examination revealed the tumor was a large epidermoid cyst and a portion of epithelial proliferation projected from the cyst wall into the dermis. The epithelial proliferation was surrounded by paucicellular fibrous stroma.

Various epidermal changes may be present in the overlying epidermis of dermatofibroma. Follicular basal cell hyperplasia is a relatively rare epidermal change found in 2-23% of dermatofibroma and it should be differentiated from basal cell carcinoma. We report a case of dermatofibroma associated with focal basal cell hyperplasia and a review of the literature.

BACKGROUND: The purpose of this study was to examine the effects of a single administration of vascular endothelial growth factor (VEGF) in promoting the angiogenesis and thereby reducing the formation of capsular contracture. METHODS: We treated 24 female Sprague-Dawley rats with (1) 5 mM Tris Buffer and 150 mM NaCl 0.1 cc, (2) VEGF 15 µg/0.1 cc, (3) VEGF 150 µg/0.1 cc during placement of the implant, or (4) VEGF 150 µg/0.1 cc and VEGF 300 µg/0.2 cc. We histopathologically measured the thickness of the capsule and the number of blood vessels. RESULTS: All experimental groups had a significant difference in the thickness of the capsule compared to the control group (P<0.001). There was no significant difference between experimental group 2 and experimental group 3. The number of blood vessels formed around the capsule was significantly greater in all the experimental groups compared with the control group (P<0.05). There was no significant difference between the experimental groups. There was a significant negative correlation between the thickness of the capsule and the number of blood vessels (Spearman's correlation coefficient, 0.2732; P<0.0001). CONCLUSIONS: A single administration of VEGF reduced formation of the capsule and increased the vascularity around the implant, supporting the hypothesis that prevention of tissue ischemia can be a treatment strategy for capsular contracture.

BACKGROUND: Photodynamic therapy (PDT) has been reported to be useful in treating nonmelanoma skin cancers and a variety of benign skin conditions including warts. However, only one case of condyloma acuminata treated with PDT has been reported in Korea. OBJECTIVE: The purpose of this study was to evaluate the complete response rate and side effect of PDT, using light emitting diode (LED) device and 20% 5-aminolevulinic acid (ALA) to treat recalcitrant verruca. METHODS: We treated 8 cases of recalcitrant verruca (3 cases of verruca vulgaris, 3 cases of verruca plana, 2 cases of condyloma acuminata) with PDT, using ALA and a 630+/-50nm LED device. The light intensity was 30-50mW/cm2 and the light dose was 50-120J/cm2. RESULTS: After treatment, two cases of verruca plana showed complete response, and one case of verruca plana, two cases of verruca vulgaris, and two cases of condyloma acuminata showed partial response. However, one case of verruca vulgaris showed no response. There was only burning sensation and/or wheals during treatments. CONCLUSION: Topical PDT may be an alternative therapy in the treatment of verruca, especially of verruca plana.

Obstetrical procedures such as prolonged obstructed labour are responsible for the majority of vesicovaginal fistula(VVF) in developing countries, while gynecological procedures are more common causes in developed countries with hysterectomy accounting for 75% of fistulae. Other less common causes of VVF include uterine cancer, pelvic irradiation, gastrointestinal pelvic surgery, tuberculosis, intra-uterine device or Bechet's disease. Although radiation techniques are being advanced, several recent studies have shown the incidence of VVF after pelvic radiation therapy for cervical cancer to range from 0.6~2%. We report, a case of 47-year-old female with VVF after pelvic radiation therapy, which was treated by neurovascular pudendal-thigh flap.
