Papular mycosis fungoides: A new clinical variant of early mycosis fungoides

Background: Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma. In early stages of the disease many different clinicopathologic variants have been observed. Observation: We report 6 patients with early manifestations of MF characterized by the sole presence of papules which, unlike the papules of lymphomatoid papulosis, did not show a tendency for spontaneous resolution. Histologic examination confirmed the diagnosis of MF in all cases. Immunohistochemical staining for CD30 was negative in all cases. Follow-Lip data showed the nonaggressive behaviour of the disease, confirming that the lesions were not manifestations of advanced MF. Conclusion: Papular MF is a new variant of early MF characterized by the presence of papules in the absence of more conventional early lesions (patches) of the disease. This variant should be added to the Ion list of clinicopathologic subtypes of MF.
