Abstract:
A 13-year-old female patient presented with itchy rashes on the right foot for 5 years. Skin examination revealed scattered flat, reddish-purple, slightly scaling papules on the inner side of the arch of the right foot, scattered light red papules on the outer side of the right great toe, and scattered domed reddish-purple papules on the right heel with collar-shaped keratinization around the base. Histopathological examination of the papule on the right heel revealed epidermal hyperkeratosis, marked hyperkeratosis around the papule, thickened granular layer and focal liquefaction degeneration of the basal layer with no obvious hyperplasia of the spinous layer; a large number of lymphocytes and plasma cells without atypia infiltrated the dermis, in which there were many small- and medium-sized dilated thick-walled blood vessels lined with prominent plump endothelial cells. The patient was diagnosed with acral pseudolymphomatous angiokeratoma of children, and treated with long-pulsed 1 064-nm Nd: YAG laser once every month. After 7 sessions of treatment, the rashes regressed and decreased in number.
