[Follicular cystitis. Case report and bibliographic review].

OBJECTIVE: To report one case of chronic follicular cystitis and to perform a bibliographic review on this pathology.

CASE REPORT: We report a case of a 70-year-old woman with an irritative voiding syndrome over an eight-month period, with several previous episodes of urinary tract infection treated by her family doctor. Bullous lesions were found in the bladder mucosa on cystoscopy. Histological tests showed lymphoid follicles at the level of the bladder mucosa, leading to the diagnosis of follicular cystitis.

RESULTS: Medical treatment was carried out with ciprofloxacin, vitamin A, and prednisone, which led to symptom remission.

CONCLUSIONS: Follicular cystitis is an entity that belongs to the group of chronic cystopathies; it is a non-specific chronic inflammatory disease characterized by the presence of large number of plasmatic cells and lymphocytes in lymphoid follicles within the bladder mucosa and submucosa; pathologic study is necessary for the final diagnosis of this entity.
