The Spectrum of Pigmented Purpuric Dermatosis and Mycosis Fungoides: Atypical T-Cell Dyscrasia

Conclusion

We propose that there is a spectrum of disease presenting as PPD or MF sitting at either end of that spectrum and an intermediate stage, where not all criteria for cutaneous lymphoma are met, characterized as cutaneous T-cell lymphoid dyscrasia. Until the potential for evolution of PPD to malignant disease is better understood, patients with unusual presentations of pigmented purpura should be further evaluated for MF.
