title: Digitate dermatosis (small-plaque parapsoriasis).
abstract: We report a 79-year-old man with a 15-year history of elongated, finger-like, erythematous patches that are symmetrically distributed on his flanks and of small, <5 cm, erythematous, slightly scaly, round-oval patches on the upper and lower extremities. The lesions were occasionally pruritic and waxed and waned over the years. His clinical and histopathologic data indicated small-plaque parapsoriasis, which is a benign entity that has been the center of controversy over the years, owing to its similarities to large-plaque parapsoriasis, which is on a spectrum with mycosis fungoides.
