title: Multiple eccrine hidrocystomas: a new therapeutic option with botulinum toxin.
abstract: BACKGROUND
  Multiple eccrine hidrocystomas are benign cystic lesions that are associated with a chronic course and seasonal variability. Even though in the literature it is presented as a very infrequent pathology, we think this is more a lack of knowledge of the existence of said pathology and the fact that patients confuse it with comedo.
  
  
  OBJECTIVE
  To treat multiple eccrine hidrocystomas of the face.
  
  
  RESULTS
  We present a case of multiple eccrine hidrocystomas of the face in a cook man. Hidrocystoma is a benign cystic tumor of the sweat glands eccrine or apocrine. Multiple eccrine hidrocystomas are benign cystic lesions that are associated with a chronic course and seasonal variability. They appear like multiple shining small papule. Although a solitary eccrine hidrocystoma can be treated easily with surgical excision, the elimination of multiple lesions is problematic because of their number and location.
  
  
  CONCLUSIONS
  The benefits of BTX-A treatment for multiple eccrine hidrocystomas include ease of application, no risk of scarring, and a good postoperative course. Because of the blockage produced by BTX-A on cholinergic terminals of the parasympathetic system that governs sweat glands secretion, it is suggested that periodic doses of BTX-A are injected in the superficial epidermis in order to treat multiple eccrine hidrocystomas.
