Linear acral pseudolymphomatous angiokeratoma of children with associated nail dystrophy


Acral pseudolymphomatous angiokeratoma of children (APACHE) is a rare entity that typically occurs on the extremities of young females. Although linear arrangement of cutaneous lesions has been rarely reported, accompanying nail dystrophy has not been linked with this condition to our knowledge. We describe a case of linearly-oriented infiltrative papules and nodules on the index finger of a young female with associated onychodystrophy. Histology demonstrated a heavy lymphocytic infiltrate with plasma cells and proliferation of blood vessels consistent with APACHE. Our case is unique given the linear array of cutaneous lesions and associated nail dystrophy.
