Acral Pseudolymphomatous Angiokeratoma

APACHE (acral pseudolymphomatous angiokeratoma of children) is a recently described benign cutaneous condition. Only a few cases have been documented to date. The disease has been previously reported in children between 2 and 13 years of age as unilateral eruptions of multiple angiomatous papules on acral sites of the hands and feet. We herein report two cases of APACHE, one occurring in a 16-year-old boy and the other in a 64-year-old woman. Unlike the previously reported cases, our female patient presented in adulthood with a single lesion on the back. Histopathologic and immunohistochemical investigations reveal characteristic features, allowing APACHE to be included among the group of cutaneous pseudolymphomas.
