Multiple Pyogenic Granulomas in Port-wine Stain after Laser Therapy / 대한피부과학회지

Pyogenic granuloma (PG) and port-wine stain (PWS) are vascular lesions that rarely occur in association. While PWSs are congenital capillary vascular malformations, PGs are acquired benign vascular proliferations. Although the pathogenesis of PG is unknown, many authors feel that they represent reactive hyperplasias, especially as they are often seen in response to trauma. We report the multiple pyogenic granulomas developed in a port-wine stain following Nd-YAG laser therapy.

Etretinate Therapy of Epidermal Nevi

Two cases of epidermal nevi treated with systemic etretinate are presented. Case 1, a 21-year-old female, had been suffered from brownish verrucous papules and plaques on the left inguinal area, thigh, lower leg and dorsum of the foot since her first month of life; and case 2, a 4-year-old boy, had been suffered from brownish verrucous papular plaques on the left chest, axilla and back since birth. In both cases, there was no family history of similar disease. On histopathological examination, case 1 showed the findings of epidermolytic. hyperkeratosis but case 2 did not, with the exception of clumping of keratohyaline granules. In the treatment with systemic etretinate, we observed marked clinical improvement in case 1, but not in case 2. Any particular side effects of etretinate were not observed during treatment. We consider that etretinate therapy is useful in treating epidermal nevus with epidermolytic hyperkeratosis histopathologically.

Two Cases of Tattoo Reaction / 대한피부과학회지

Tattooing has been performed the for cosmetic purpose by many beautician in the beauty parlors without having been any medicalknowledge. This has resulted in various serious complications. One patient is a 56-year-old female, who had been developed pruritic erythernstous indurated plaques on the tattooing sites about 3 months after getting tattoo. Skin biopsy findings revealed granulomatous inflamrnation and patch test showed positive reaction to potsssiurn dichromate. The other patient is a 55-year-old female, who had been developed erythematous papules on the both lips of tattooing sites about 1 year after getting tattoo. Skin biopsy findings revealed lichenoid resction. Patch test showed positive reactions to reornycin eulfate and nickel sulfate. Patch test of as is revealed positive reactions to red color.

A Case of Paraffinoma / 대한피부과학회지

We experienced a 57-year-old male patient who have had multiple coin sized, erythematous, psinful, indurated ulcerations with purulent discharge on the right calf area since 10 years before. Previously he received injections of paraffin in the lesion site for correcting the thinning of right calf due to complication of pyoderma. Histopathologic examination showed "Swiss cheese" appearance of parsffinoma. Good result was obtained after treatment with surgical excision and split thickness skin graft.
