ABSTRACT

BACKGROUND: Numerous modalities have been used to treat scars and wrinkles. Most of them are not satisfactory and always have some degrees of complications. OBJECTIVE: This study was performed to evaluate the effect of the combination therapy of superpulse CO2 laserbrasion and dermabrasion(laser-dermabrasion) in surgical treatment of scars and wrinkles and propose that it can be a effective method to improve cosmetic results. METHODS: Twenty-eight patients with scars and wrinkles were treated using superpulse CO2 laserbrasion followed by dermabrasion. Questionnaires were completed for clinical assessments by the patients and clinicians. RESULTS: The results are summarized as follows. 1. Excellent and good results were achieved in 83.3% of scars in clinician's assessments and in 79.2% of scars in patients' assessments. 2. Excellent and good results were achieved in 100% of wrinkles in both of clinician's and patients' assessments. 3. The degrees of satisfaction were highest during 6 to 12 months after laser-dermabrasion and maintained high over 12 months. 4. Minimal and tolerable complications developed in 9 patients such as focal hyperpigmentation, changes of skin texture, erythema, milium and acne flare-up. CONCLUSION: We propose that the laser-dermabrasion would augment the effects of both laserbrasion and dermabrasion to improve cosmetic results in treatment of scars and wrinkles with minimal risks and low costs.

ABSTRACT

Tufted angioma, a relatively rare, benign, slowly progressive angiomatous proliferation in children, was first described as a variant of hemangioma by Nakagawa in 1949. It occurs most commonly on the neck and upper trunk as red to purple coalescent papules or nodules. More than 50% of these cases occur during the first year of life. It appears to be benign despite the progressive spread of this tumor and no malignant changes have been reported. The characteristic histological feature is that multiple small well-circumscribed angiomatous tufts and lobules scatter in a cannonball arrangement through the dermis with peripheral dilated crescent-shaped lymphatic channels. We report two cases of tufted angioma developed in infants. Routine biopsy specimens and immunohistocheinical stainings showed typical features of tufted angioma.

ABSTRACT

Lichen striatus is an uncommon unilateral inflammatory linear papular dermatosis of uncertain etiology. It most commonly affects the extremities and has a self-limiting course. Nail involvement in lichen striatus is a very rare reported finding and is a cause of a deformity of the nail plate. It tends to have a more prolonged course for cutaneous eruptions than disease limited only to the skin. Characteristic histopathological features are important to differentiate this condition from other linear lesions that may interfere with nail growth. Three cases of lichen striatus with onychodystrophy are presented herein.
