Chronic Infection and Nodule Formation following Deoxycholate Injection

Area of Science:

• Aesthetics
• Dermatology
• Cosmetic Procedures

Background:

• Aqualyx is an European Union-approved injectable solution for localized fat reduction, composed of deoxycholate, saline, and buffering compounds.
• It is exclusively sold to healthcare professionals trained in intralipotherapy.
• Improper administration can lead to adverse events.

Purpose of the Study:

• To report a case of severe complications following the non-professional and superficial administration of Aqualyx.
• To highlight the importance of proper training and competence in cosmetic procedures.

Main Methods:

• A case report detailing patient presentation and clinical course.
• Diagnostic ultrasound to characterize the lesion.
• Clinical observation of treatment outcomes.

Main Results:

• The patient experienced severe pain, inability to sit, localized skin necrosis, and palpable collections post-injection.
• Ultrasound revealed a superficial hypoechoic lesion without deeper infection.
• Multiple painful nodules ruptured, causing purulent and bleeding lesions.

Conclusions:

• This case underscores the critical need for qualified healthcare professionals and appropriate technique when administering injectable fat-dissolving treatments like Aqualyx.
• Suboptimal administration can result in significant morbidity and necessitate further medical intervention.
