A Case of Impetigo Herpetiformis Treated with Isotretinoin / 대한피부과학회지

Impetigo herpetiformis is a rare and severe pustular disorder which primarily occurs in pregnancy. Etretinate and acitretin are effective in impetigo herpetiformis with systemic steroid. A major concern with the use of systemic retinoids is their high teratogenic potential. Isotretinoin is another retinoid but its teratogenic potential lasts only for two months. Hence, isotretinoin may be used to treat women of childbearing years with impetigo herpetiformis. We report a case of impetigo herpetiformis in a 26-year-old woman whose condition was improved with isotretinoin.

The Utility of Dermoscopy for in vivo Detection and Treatment of Pediculosis Palpebrarum / 대한피부과학회지

Pthiriasis palpebrarum is a rare disease in which crab lice infest the eyelashes. It can cause pruritic lid margins, and it is difficult to diagnose and treat. We diagnosed and managed a case of pthiriasis palpebrarum in the right upper eyelid of a 35 month-old male child. We removed the lice and nits by pulling with fine forceps using dermoscopy. After treatment, all lice and nits had been eradicated without recurrence. We suggest that this is an effective, safe method for diagnosis and treatment of pthiriasis palpebrarum.

A Case of Malignant Glomus Tumor / 대한피부과학회지

Malignant glomus tumor, or glomangiosarcoma, is a very rare neoplasm that typically arises from a benign glomus tumor. Despite having the histological features of malignancy, these tumors usually do not metastasize. We report a case of malignant glomus tumor on the finger of an 18-year-old man. By histology, round to ovoid tumor cells showed a uniform appearance of round nuclei. Many mitotic figures and nuclear atypia were observed. Immunohistochemically, vimentin and alpha-smooth muscle actin showed intense staining. This case was considered to be a malignant glomus tumor. Thus, it was a glomangiosarcoma arising de novo.
