title: A variant of palpable migratory arciform erythema.
abstract: Palpable migratory arciform erythema is a T-cell pseudolymphoma with no well-established treatment. The disease is rarely reported in the literature, perhaps because it is difficult to diagnose. We present a case of a variant of PMAE in a 30-year-old healthy man with no history of medication use and erythematous to violaceous annular and arciform plaques on his face, scalp and trunk. This case is of particular significance because gene rearrangement studies and histopathologic findings are concerning for folliculotropic mycosis fungoides while the clinical course does not support this diagnosis. The authors' emphasize that clinical history is imperative for definitive diagnosis of palpable migratory arciform erythema as it can clinically and histopathologically resemble other cutaneous lymphocytic diseases.
