Using Avidin-Biotin immunoperaxidase method, we investigate the distribution patterns of factor VIII related antigen in various areas of skin lesions of 14 granuloma pyogenicum. and in the skin lesions of 5 capillary hemangioma and 5 normal skin. The results are summarized as follows: 1. Factor VIII related antigen was detected in 9 of 14 cases of granuloma pyogenicum, in 4 of 5 cases of capillary hemangioma, and in 5 of 5 cases of normal skin. 2. In the lesions of granuloma pyogenicum the areas with prominent capillary endothelial cell proliferation had less positivity than the vascular areas. And the areas with relatively large vesels in the lesions of granuloma pyogenicum had similar positivity as capillary hemangioma. 3. The lesions of granuloma pyogenicum and capillary hemangioma had less positivity than the vessels of normal derrnis.

Reconstruction of extensive soft tissue defects of the lower extremity, especially when complicated by open fracture and bone loss, is usually a difficult problem for the plastic surgeon. Many methods have been devised to treat these conditions Musculocutaneous flaps add a valuable surgical alternative that bring vascularized cover to the defects, and the free microvascular transfer of these flaps gives the surgeon an added dimension of versatility. The latissimus dorsi is an extremly reliable musculocutaneous flap with a long, large-caliber vascular pedicle, so that dissection of the muscle can be performed with relative ease. The size of the latissimus dorsi muscle lends itself to coverage of large defects. While these characteristics appear to make the free latissimus dorsi musculocutaneous transfer ideal in many circumstances, it has some disadvantages. At the recipient site, the flap is ofter too bulky, and donor-site closure requires skin grafts if the flap is wider than 10cm. These skin grafts on the posterior thorax seriously detract from the final appearance of the donor site. The authors have experienced 12 cases of reconstruction of extensive lower extremity soft tissue defect in which the latissimus dorsi muscle alone was transferred and covered with a split-thickness skin graft. This method improves the recipient-site contour by decreasing the bulk of the flap and it also improves the donor-site appearance. We described technical considerations in each case and the advantages of free latissimus dorsi muscle flap and skin graft for the reconstruction of extensive soft tissue defect in the lower extremity.

We have experienced 2 cases of lichen planus. Case 1 was a. 76-year-old male who has suffered from discrete, scaly, round to polygonal papules on the trunk and the e:xtremiities for 3 months. The VDRL test for syphilis was reactive at a titer of 1:2 and the TPHA test was positive. The skin lesions were responded to 3 weekly injections of benzathine penicillin 2.4 million units, Case 2 was a 17-year-old male who has suffered from discrete, erythematous to violaceous colored, flat papules on the right shin for several months. He has treated with oral medication of griseofulvin. After 2 weeks of the medication, the skin ]esions showed improvement with gradual reduction of pruritus and flattening of the papules. About one month of the medication, all skin lesions cliappeared with dark brownish hue and hypopigmentation. And recurreci lesions after stopping medication are disappeared after 2 months of retreatment with griseofulvin.

The perichondrium has neochondrogenic potential. Many authors have published their study for the cartilage regeneration from perichondrium and the clinical uses of perichondrial graft. How is the difference of thickness of the regenerated cartilage after crushing the free perichondrial graft, compare with uncrushed graft? In this study, the perichondrium was obtained from rabbit, ears, and sectioned 10x10 mm slices. The uncrushed and crushed perichondriums were grafted into subcutaneous layer of back. After the 2,4 and 8 weeks, authors obtained regenerated cartilage from both crushed and uncrushed free perichondrial graft from rabbit back, examined the survival rate and thickness by histologic study.The results are as follows: 1. The survival rate was no difference between the uncrushed perichondrium & crushed perichondrium (p>0.05). 2. The cartilage from the uncrushed perichondrium was thicker than the crushed perichondrium, at only 8 weeks(p<0.01). 3. The thickness of regenerated cartilage was similar to the cartilage of the donor site of free perichondrial graft at 4 weeks(p>0.05).

A retrospective, multivariate statistical analysis of 394 patients who underwent cleft palate repair was performed to document the incidence of postoperative oronasal fistula formation, and to assess possible contributing factors. Fistulas of the secondary palate were included, but nasal-alveolar fistulas and intentionally unrepaired anterior palatal fistulas were excluded. Postoperative oronasal fistulas occurred in 25 of the 394 patients(6.35%). The mean age at repair was 16.4 months, and mean follow-up period was 2.5 years. Several variables that are included sex, age, extent of clefting(as estimated by the Veau classification), type of repair, and experience level of the operating surgeon were analyzed by means of the log-rank test to determine their significance in postoperative fistula formation. Sex (p=0.077), age(p=0.538), and experience level of the operating surgeon(p=0.094) did not significantly affect the rate of fistula formation. However, extent of clefting(p=0.005) and type of repair(p=0.001) are the strongest predictor of the occurrence of a cleft palate fistula.

Trichloroethylene is a very common chemical used principally as a solvent and a degreasing agent in industry, We have experienced a case of toxic erythema, toxic hepatitis, and subsequent exfoliative dermatitis possibly due to trichloroethylene in a 23-year-old male. He had dealed with a cleaning process with trichloroethylene in a factory of stainless steel materials. We report our case with the review of the toxicity of trichoroethylene.
