INTRODUCTION: Hidrocystomas are skin-colored or translucent cysts, single or multiple, appearing on the face. They originate in the eccrine or apocrine sweat gland and are sometimes disfiguring. They can be excised by surgery, electrodissection, or by caustics, but are usually recurrent and the treatments can leave scars or dyschromia. Botulinum toxin A (BoNT-A) has been suggested as therapy in few cases in the literature.
OBJECTIVE: To analyze the effects of BoNT-A in cases of facial hidrocystomas.
METHODS: Retrospective observational study of case series. Patients with facial hidrocystomas treated with BoNT-A at the Cosmiatry Outpatient Dermatology Clinic of the Hospital do Servidor Público Municipal de São Paulo, were evaluated.
RESULTS: Of the 13 patients evaluated, 5 were included, the largest case series described so far. Of these, all lesions treated showed clinical improvement during the period evaluated. Four patients showed partial regression and one, total regression of the lesions.
CONCLUSION: In this series of cases, BoNT-A showed positive and long-lasting results in the treatment of facial hidrocytsomas, with no adverse effects.
