[Multiple filiform hyperkeratoses].

We report on a 41-year-old female patient who presented with a 3-year history of multiple filiform hyperkeratoses on the trunk. The family history revealed that her uncle had similar skin lesions. Another patient presented with filiform hyperkeratoses only on the palms of the hands and soles of the feet. This condition, referred to in English as multiple minute digitate hyperkeratoses, is a rare, mostly hereditary, disorder of cornification. As yet there is no official name for this dermatosis in German; we propose "multiple filiforme Hyperkeratosen".
