Three clinically oriented cosmetic/aesthetic studies stood out today: a large outpatient cohort shows ultrasound-guided vacuum-assisted excision (VAE) of benign breast lesions delivers excellent cosmetic and psychological outcomes with low complications; a descriptive ultrasound mapping study of gluteal fillers proposes a practical imaging framework to enhance safety; and a case series warns of severe adverse reactions after off-label intradermal exosome injections, underscoring regulatory needs.
Research Themes
- Minimally invasive aesthetic procedures with quantified cosmetic and psychological outcomes
- Imaging-guided safety frameworks for soft-tissue fillers
- Regulatory and safety signals for off-label biologic cosmeceuticals

1. Clinical efficacy and psychological benefits of ultrasound-guided vacuum-assisted excision in outpatient management of benign breast lesions.
In a retrospective cohort of 1,413 patients (2,008 lesions), outpatient ultrasound-guided VAE showed low complication rates (infection 0.57%, hematoma 16.63%, mostly observed), high cosmetic success (98.91% rated excellent), and significant anxiety reduction (SAS 47.47±8.20 to 43.27±7.80; P<0.001). Fibroadenoma predominated (78.14%), and incidental carcinoma occurred in 0.25%.
Impact: This large real-world cohort provides robust evidence that outpatient VAE achieves excellent cosmetic and psychological outcomes with low adverse events, supporting broader adoption in benign breast care.
Clinical Implications: Supports VAE as a first-line outpatient option for benign breast lesions, with attention to pathology review and follow-up given the small incidence of malignancy. Incorporating peri-procedural anxiety assessment may improve patient-centered care.
Key Findings
- Outpatient VAE in 1,413 patients (2,008 lesions) had low complications: infection 0.57%, hematoma 16.63% (mostly managed conservatively), and oozing hemorrhage 18.54% resolving without intervention.
- Cosmetic outcomes were excellent in 98.91% with 98.94% overall satisfaction; mean procedure time was 23.33±9.26 minutes.
- Anxiety significantly decreased post-procedure (SAS 47.47±8.20 to 43.27±7.80; P<0.001) with a 72.03% remission rate; incidental carcinoma was identified in 0.25%.
Methodological Strengths
- Large single-institution cohort with 1,413 patients and standardized outpatient workflow
- Comprehensive outcomes including complications, cosmetic ratings, and validated anxiety scores
Limitations
- Retrospective design without a control group limits causal inference
- Long-term oncologic and cosmetic durability beyond early follow-up not detailed in the abstract
Future Directions: Prospective multicenter studies comparing VAE with surgical excision and vacuum devices, with standardized long-term cosmetic and quality-of-life endpoints and cost-effectiveness analyses.
2. Reviewing the Ultrasound Anatomy of the Gluteal Region and the Mapping of Fillers.
In 110 patients undergoing gluteal filler procedures, dermatologic ultrasound (2–8, 3–15, 3–22 MHz probes) enabled systematic quadrant-based mapping of the gluteal region and accurate characterization of common filler materials. The authors propose a standardized ultrasound protocol to delineate anatomy, visualize filler distribution, and facilitate early complication detection.
Impact: Introduces a practical, standardized ultrasound mapping framework for gluteal fillers, addressing a critical safety gap amid rising demand for buttock augmentation.
Clinical Implications: Supports pre-/post-procedural ultrasound to guide injection planes, document filler distribution, and enable early detection and management of complications in gluteal augmentation.
Key Findings
- A cohort of 110 patients was systematically evaluated using multi-frequency ultrasound with prone positioning and quadrant-based mapping of the gluteal region.
- Ultrasound was non-invasive, dynamic, sensitive, and accurate for identifying ultrasonographic characteristics of major exogenous fillers in the gluteal region.
- A standardized mapping method is proposed to improve differentiation of filler materials and enable early diagnosis of complications.
Methodological Strengths
- Systematic anatomical framework with quadrant-based mapping using multi-frequency probes
- Inclusion of real-world patients with and without complications across 2023–2025
Limitations
- Single-center descriptive design without quantitative diagnostic accuracy metrics
- Lack of histopathologic or surgical correlation and external validation
Future Directions: Prospective validation of the mapping protocol with inter-rater reliability, diagnostic accuracy against reference standards, and integration into complication triage algorithms.
3. Adverse Reactions Following Intradermal Injection of Exosome-Based Formulations: A Case Series.
Four women developed persistent erythema, nodules, granulomatous inflammation, and scarring after off-label intradermal injections of exosome-based products administered in a nonclinical setting. Despite systemic/intralesional steroids, laser, and surgical removal, lesions incompletely resolved with residual scarring, highlighting significant safety and regulatory concerns.
Impact: Provides timely safety evidence that off-label intradermal exosome injections can cause severe, persistent complications refractory to standard therapies, informing practitioners and regulators.
Clinical Implications: Avoid intradermal use of unapproved exosome products; counsel patients regarding risks; consider early biopsy and anti-inflammatory management; report cases to authorities to support regulation and product standardization.
Key Findings
- All four patients developed persistent inflammatory lesions (erythema, nodules, granulomatous inflammation) and scarring after intradermal exosome injections performed in a nonclinical setting.
- Multi-modal treatments (systemic/intralesional corticosteroids, laser therapy, surgical removal) yielded incomplete resolution with residual scarring.
- Highlights off-label, unregulated use of exosome-based formulations as a potential cause of serious cutaneous adverse events.
Methodological Strengths
- Detailed clinical documentation of presentation, treatments, and outcomes across multiple therapeutic modalities
- Safety signal identification in real-world aesthetic practice context
Limitations
- Small case series (n=4) limits generalizability and causal attribution
- Product composition and lot-to-lot variability not characterized; follow-up duration not specified
Future Directions: Establish regulatory oversight and standardized quality controls; conduct mechanistic studies of foreign-body/granulomatous reactions to exosome formulations; develop evidence-based guidelines on routes of administration.
