Abstract
The histopathology showed epithelial changes characterized by compact hyperkeratosis with parakeratosis, mild to moderate acanthosis, severe spongiosis and leukocyte exocytosis with a dense lymphohistiocytic inflammatory infiltrate of polymorphonuclear cells, some eosinophils and lymphoid follicles with germinal centers [Figure 2]a and [Figure 2]b.{Figure 2}{Figure 3} Answer Follicular cheilitis.[1],[2] Clinically, follicular cheilitis is a chronic disease characterized by dry scaly lips with acute relapses of pain, pruritus, edema, yellowish crusts, exudation, fissures and secondary ulceration of the lip, all worsened by sun exposure.[5] In addition, the lymphoid follicles with germinal centers observed on the histopathology of the patient are considered to be a pathognomonic finding of follicular cheilitis.Frictional contact cheilitis is associated with repeated trauma.With regard to the treatment of follicular cheilitis, the most important recommendations are the reduction of sun exposure and the use of sunscreen every 2 hrs and physical barriers.
