When the face is affected, the folds deepen to form a "lion face"

Introduction When the face is affected, the folds deepen to form the "lion face": more common in the primary skin T-cell lymphoma plaque stage, which progresses from the erythema stage, or occurs on normal skin, which is irregular and has a slightly higher boundary. Plaques, the color is dark red to purple, and the hardness is not equal. It can be self-resolving, or it can be fused to form large plaques. The edges are ring-shaped, bow-shaped or limp-like.

In the primary cutaneous cutaneous T-cell lymphoma plaque, most patients have diagnostic value for histopathology, which is characterized by epidermal epithelial phenomenon and Pautrier microabscess. Banded pleomorphic cell infiltration occurs in the upper part of the dermis, including normal lymphocytes, histiocytes, eosinophils, and plasma cells. The difference from the erythema phase is that some mononuclear cells are heterotypic T lymphocytes, which are large and deeply stained, have a characteristic cerebral gyrus, and the mononuclear cell infiltration can also be seen in the epithelium (especially the hair follicle). .
