Successful Treatment of Anogenital Wart with a Topical Vitamin D3 Derivative in an Infant

Anogenital warts are an infectious disorder of the anogenital lesion caused by one or more human papilloma viruses. Verruca is commonly treated with freezing with liquid nitrogen, laser therapy or application of imiquimod. Such ablative treatment may cause pain and scars on the anogenital lesion. We herein report an infant case of anogenital wart which was successfully treated with a topical vitamin D3 derivative. Topical application of a vitamin D3 derivative may be an alternative therapy for anogenital warts in infants

An Adolescent Patient with Scabies Mimicking Gottron Papules

Atypical features of scabies occur in infants and children and patients with prolonged use of corticosteroids or immunosuppression. We report a non-immunosuppressed 15-year-old female case of scabies showing scaly reddish papules over the proximal interphalangeal joints mimicking Gottron papules in classic dermatomyositis. Periungal erythema was also seen. Four months’ topical corticosteroids from previous clinics had been used. Dermoscopic findings were consistent with typical pictures of scabies. Scraping of hand crusts demonstrated scabies mites and ova. Skin lesions of the patient were cured with oral ivermectin and topical 10% crotamiton. This case suggests that a lesion resembling Gottron papules may be added to the panel of unusual presentations of scabies

Allergic Contact Dermatitis with Diffuse Erythematous Reaction from Diisopropanolamine in a Compress

Compresses containing a nonsteroidal antiinflammatory drug (NSAID) are commonly used in Japan. However, this treatment may induce both allergic and photoallergic contact dermatitis from the NSAIDs and their ingredients. Here, we describe a case of allergic contact dermatitis with diffuse erythematous reaction due to diisopropanolamine in the applied compress. The absorption of diisopropanolamine might have been enhanced by the occlusive condition

Dermoscopy for Tick Bite: Reconfirmation of the Usefulness for the Initial Diagnosis

Ticks transmit a variety of infectious diseases. Diagnosis requires verification of a tick's presence. Here, we describe a 61-year-old woman bitten by an eight-legged nymphal Amblyomma testudinarium. We re-emphasize the usefulness of dermoscopy for identifying signs of the bite and determining the species of the biting tick
