research Cutaneous Lymphadenoma Is a Distinct Trichoblastoma-like Lymphoepithelial Tumor With Diffuse Androgen Receptor Immunoreactivity, Notch1 Ligand in Reed-Sternberg–like Cells, and Common EGFR Somatic Mutations
This study suggests that cutaneous lymphadenoma is a distinct benign lymphoepithelial tumor characterized by androgen receptor expression, hair follicle stem cell markers, and common EGFR gene mutations.
