RESUMO
BACKGROUND: There exists a treatment challenge with periungual warts. Topical immunotherapy with diphenylcyclopropenone (DPCP) has recently been reported to be an effective treatment for recalcitrant warts, including periungual types. OBJECTIVE: We aimed to evaluate the effectiveness and preference of topical immunotherapy with DPCP in treating periungual warts. METHODS: Twenty-seven patients with periungual warts who were treated with DPCP immunotherapy (2007 through 2010; Dongguk University Ilsan Hospital, Goyang, Korea) were retrospectively recruited. Other treatment modalities were also used in some patients. Lesions were grouped into the types according to the following locations: proximal nail fold, lateral nail fold and hyponychium. Total and group clearance rates as well as treatment periods according to location and disease duration were evaluated. A patient questionnaire was performed to assess the satisfaction for the treatments in those who received multiple therapies. RESULTS: Total success rates were 85% (by subjects) and 91% (by individual lesions). Success rate and treatment period for proximal nail fold type seemed more desirable than other locations. Success rate decreased and treatment period increased as disease duration increased. The questionnaire revealed a significantly higher satisfaction rate for DPCP immunotherapy than for cryotherapy and pulsed-dye laser. CONCLUSION: Topical immunotherapy with DPCP is an effective and preferred method in the treatment of periungual warts.

Vitiligo is an acquired cutaneous disorder of pigmentation with no definite etiology. Although there are a number of treatment modalities including phototherapy, topical corticosteroids and topical immunomodulators, few studies on the effect of systemic cyclosporine for the treatment of vitiligo have been conducted. We have experienced the improvement of vitiligo lesions after 8 months of systemic administration of cyclosporine (2.5~3.3 mg/kg/day) in a patient with vitiligo and atopic dermatitis. We believe this case report warrants further investigations of cyclosporine for the treatment of vitiligo in terms of mechanisms and clinical outcomes as well.

Papular elastorrhexis is a rare cutaneous disorder that occurs predominantly during adolescence. The disorder is characterized by asymptomatic indurated white or flesh papules showing decreased and fragmented elastic fibers in the dermis. We herein report on a 12-year-old girl with multiple asymptomatic white, nonfollicular, firm papules scattered on the extremities and trunk. Histological examination revealed focal areas showing increased layers of collagen fibers and decreased and fragmented elastic fibers in the upper dermis.

Fixed drug eruption is a distinctive and clinically recognizable entity that is characterized by well-demarcated erythematous plaques recurring in exactly the same sites as on previous occasions. Unlike the pigmenting form of fixed drug eruption, nonpigmenting fixed drug eruption leaves no pigmentation when it resolves. We now report the case of a 44-year-old man who presented with diffuse ill-defined erythematous patches on both hands, feet and lower legs with a burning sensation, which is considered an atypical manifestation for fixed drug eruption. The patient had a history of similar skin lesions developing after medications on the corresponding regions. The patch test with suspected drugs showed negative reactions on both lesions and unaffected sites. The lesions were reproduced on the oral provocation test with codeine and resolved without pigmentation. The patient was diagnosed with nonpigmenting fixed drug eruption due to codeine.

Atypical fibroxanthoma is an uncommon spindle cell tumor that has a clinically benign course despite the presence of bizarre xanthoma cells. A 90-year-old female presented with a 2-month history of an ulcerative plaque on the right cheek. The initial punch biopsy revealed a benign histological appearance with prominent xanthomatous cells, but the specimen excised afterwards showed malignant features with a spindle and epithelioid cell proliferation with pleomorphism and atypia. The tumor cells stained positively for vimentin and CD68, they were partially positive for CD99 and CD10 and they were negative for CD34, S100, p63, desmin and actin. We report here on a case of atypical fibroxanthoma masquerading as xanthogranuloma.

Pacinian neuroma, also known as hyperplasia and/or hypertrophy of pacinian corpuscles is a rare skin condition usually occurring in the hand. Although it is known to cause pain and tenderness on the affected skin, asymptomatic cases have also been reported. We report a 46-year-old male monk who presented with asymptomatic skin lesions of paler color than the adjacent normal skin on the tips of the fingers of both hands. The 3 mm punch biopsy conducted on the lesion showed an increased number of onion bulb-like structures with a nerve fiber in each center. The patient was diagnosed with pacinian neuroma and has been under regular follow up without treatment.
