“…Although local excision has commonly been employed in the treatment of solitary adnexal tumors of the face, head, and neck, alternative treatments, including electrosurgery, cryosurgery, and ablation with neodymium-doped YAG and carbon dioxide (CO 2 ) laser therapy have also been described. [7][8][9][10][11] Rallan and Harland reported the treatment of multiple facial trichoepitheliomata, tumors with similar histologic characteristics to trichblastomas, using a combination of Er:YAG and CO 2 laser ablation. 12 To our knowledge, this is the first documented case of the use of Er:YAG laser ablation and PDT to treat trichoblastomas and the first comparative study of Er:YAG resurfacing, imiquimod, and PDT in the treatment of these neoplasms.…”
