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.

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.
