BACKGROUND: Trichloroacetic acid chemexfoliation has gained popularity and is widely used cosmetically. The depth of the wound caused by the various dilutions of TCA is paramount to the therapeutic efficacy. Therfore rational use of TCA chemexfoliation requires a clear understanding of the expected depth of destruction caused by a given dilution. OBJECTIVE: The purpose of this stuely is to quantitate the wound deptlw produced by varying concentrations of TCA. We have stirdied takie effects of consecutive applications, occlusion and tretinoin pretreatment on wound depth in TCA clinimical peeling. METHODS: Various concentrations of TCA and distilled water were aplied to two pairs of test sites of a guinea pigs back in a uniform fashion with cotton-tip applicators and then we have measured the mean depth of epidermal necrtsis mieroscopically by using Visual Imagc Data Analysis System. RESULTS: 1. Depths of wounds createdly threre consecutive applications of 20, 35% and 50% TCA were deeper than those of wounds by a single application of TCA. 2. Depths of wounds created by application of TCA with the occlusive method were deeper than those of the open method. Therefore the effect of occlusion is to enhance the penetration of TCA. 3. Depths of wounds pretreatwi with 0.05 % tretinoin daily for 7 days are deeper than those of the control in 50% TCA chemical peeling. Therefore the effect of 0.05% retinoin pretreatment is to enhance the penetration of TCA. CONCLUSION: This study showed that consecutive applications, oeclusion and tretinoin pretreatment in TCA chemexfoliation enhance the peietration of TCA.

We report a typical case of Hunters syndrr me in a 9 year old boy, who presented with firm skin colored nodules that coalesce to form a reticular pattern on a symmetrical rea between the angles of the scapulas, which is regarded as the pathognornonic cutaneous rnarker, for Hunters syndrome. He also showed growth retardation, clear corneas, hepatomegaly, attertich deficit and mild mental deterioration. The skin biopsy specimen taken frorn a typical nodule shows loosely arranged collagen fibers with massive mucinous material which stains positively with aliar blue at both pH 2.5 and 0.5, metachromatic granules within fibroblast stained with toluidine blue.

Basal cell carcinoma(BCC) is the most common human malignancy. It involves the face and neck most frequently. However, BCC can very rarely occur on external glenitalia such as scrotum and vulva. We report two cases of serotal and vulvar BCCs in a 67 year old imale and a 43 year old female. He suffered from well defineril erythematous to violet colored plaque with central erosion on the left scrotum for 5 years. She had a brown black colored plaque on the left vulva for 8 years. They did not show any metastatic foci from g!rimary cutaneous lesions, and underwent surgical excision and curettage respectively.

The radiologic and clinical findings of foreign bodies in the chest of children are well recognized. Foreign bodies in adults are infrequent, however, and the radiologic findings of these unusual circumstances have rarely been described. We classified various thoracic foreign bodies into three types according to their cause: Type I, Aspiration, Type II, Trauma or Accident; Type III, Iatrogenic. This pictorial essay will illustrate the radiologic findings and consequences of thoracic foreign bodies in adults, which have rarely been described in the radiologic literature. The clinical significance of thoracic foreign bodies will be also be discussed.
