A patient with folliculitis dissecans who did not respond to antibiotic therapy received four monthly sessions of intradermal administration of 100 IU of botulinum toxin A. Four months after the treatment, a complete recovery of the affected area of the patient's scalp was observed. A biopsy taken from the lesional area showed the presence of Staphylococcus lugdunensis and Staphylococcus aureus, both of which were found to be resistant to erythromycin. It was observed that the toxin had no effect on the viability or biofilm production of the Staphylococcus strains. This indicates that the healing effect of the toxin was associated with the host response alone.
