Single cell sequencing delineates T-cell clonality and pathogenesis of the parapsoriasis disease group

Mycosis fungoides (MF), the most common cutaneous T-cell lymphoma, is often underdiagnosed in early stages due to similarities with benign dermatoses such as atopic dermatitis (AD). Furthermore, the delineation from so-called "parapsoriasis en plaque," a disease that can appear either in a small- or large-plaque form, is still controversial.
