Lichenoid mycosis fungoides: Report of a case with lichen planus ‐like histopathologic features

We report a 61-year-old patient with 5-year history of generalized violaceous patches and plaques. His biopsy revealed a marked lichenoid band-like infiltrate of inflammatory cells along the basal layer with basal layer vacuolar changes; the diagnosis of lichen planus was first made histopathologically. Several biopsy specimens, clinicopathologic correlation, and immunohistochemistry findings confirmed the diagnosis of lichenoid MF. Awareness of peculiar histopathologic findings of MF is essential to avoid a potential misdiagnosis. When in doubt, multiple biopsies with other diagnostic methods should be employed.
