Morphea-like lesions after botulinum toxin A injections – JAAD Case Reports

https://www.jaadcasereports.org/article/S2352-5126(20)30632-9/fulltext

Clinically visible atrophy of the mimetic muscles after cosmetic BTXA injections has not yet been reported in the dermatologic literature. Yet, when assessed by magnetic resonance imaging, the volume of the mimetic procerus muscle decreases after a single BTXA injection for about 12 months.



We propose that the pathologic mechanism is either related to focal neurogenic atrophy of the injected muscle or to dislocation of minuscule amount of syringe lubricant into the injected drug. If the latter is the mechanism, flushing of the syringe, or avoiding of tapping on it, would likely minimize the risk of its occurrence.

5‐Aminolevulinic acid patch (Alacare) photodynamic therapy for actinic cheilitis

Data from a prospective 12‐month follow‐up study on 21 patients – Radakovic – 2020 – Journal of the European Academy of Dermatology and Venereology – Wiley Online Library

Actinic cheilitis (AC) is a variant of actinic keratosis (AK) affecting the lips and caused by chronic ultraviolet exposure.

The present prospective study on Alacare patch PDT for AC confirms its high clinical efficacy, good tolerability and favourable cosmetic effects.

Alacare patch PDT should be considered as a valid treatment option for patients with AC.
