We report a 48-year-old woman who presented with waxing and waning papulovesicles of 4 years' duration. Histologic examination revealed a folliculotropic, small cell dominant, T cell lymphocytic infiltrate unaccompanied by follicular mucin deposition and with scattered intrafollicular and perifollicular CD30+ cells. A diagnosis of type B follicular lymphomatoid papulosis (LyP), rather than mycosis fungoides (MF), was made on the basis of her clinical presentation, which included spontaneously resolving, waxing and waning papules that healed with scarring. Type B follicular LyP is a rare form of LyP.
