Cutaneous granuloma fissuratum, also known as granuloma fissuratum and acanthoma fissuratum, is an uncommon skin lesion resulting from chronic low-grade trauma. It arises as a result of ill-fitting eyeglasses and classically involves one or both of the superior retroauricular areas where the bow of the frames rests on the area of the superior sulcus. It may alternatively involve the lateral bridge of the nose due to trauma from a nose pad.

Granuloma fissuratum manifests as a skin-colored or pink papule or nodule of rubbery to firm consistency. Auricular lesions commonly exhibit a central furrow or groove corresponding to the area of contact with the glasses' frame.
