Ultrasound Pattern of Congenital Smooth Muscle Hamartoma of the Skin.

Smooth muscle hamartoma (SMH) of the skin is a cutaneous benign proliferation of mature smooth muscle. Congenital SMH (CSMH) of the skin represents the most frequent type, and to date, there are no reports on its ultrasonographic pattern. A retrospective study of the color Doppler ultrasound (US) images of six CSMH patients at high and ultra-high frequencies was performed.

The Transformative Potential of AI in Ultrasound for Facial Aesthetics.

Background: The integration of artificial intelligence (AI) and ultrasound (US) technology is reshaping facial aesthetics, providing enhanced diagnostic precision, procedural safety, and personalized patient care. The variability in US imaging, stemming from patient anatomy, operator skills, and equipment diversity, poses challenges in achieving consistent and accurate outcomes. AI addresses these limitations by standardizing imaging protocols, automating image analysis, and supporting real-time decision-making.

Update on the role of color Doppler ultrasound in hidradenitis suppurativa: a game-changer.

Hidradenitis suppurativa has greatly benefited from the insights of color Doppler ultrasound. Thus, ultrasonography has helped prove the follicular link of this disease and has ruled out the primary involvement of the apocrine glands, which, in the old days, was supposedly the cause of the disease. Importantly, ultrasound can detect subclinical anatomical information in HS that cannot be deducted from the clinical examination.

Ultrasound in Skin Cancer: Why, How, and When to Use It?

Background: Skin cancer is the most common cancer in human beings. Ultrasound is a powerful and non-invasive imaging technique that has expanded its use in dermatology, including in the skin cancer field. The full range of critical anatomical information provided by ultrasound cannot be deduced from a naked eye examination, palpation, or other imaging techniques such as dermoscopy, confocal microscopy, magnetic resonance imaging, or PET-CT (Positron Emission Tomography-Computed Tomography).

Advances in image-based diagnosis of nail disorders.

This paper provides a comprehensive overview of image-based techniques, particularly focusing on their applications and advancements in the context of nail disorders. Nowadays, high-resolution digital cameras and dermoscopes enable dermatologists to capture detailed images of nail abnormalities, facilitating early diagnosis and meticulous tracking of disease progression. Onychoscopy is now a routine technique with well-known criteria for the diagnosis, but recent developments allow us to visualize certain diseases better.

Evaluation of Ultrasound Changes With the Use of Microneedling Versus Fractional CO2 Laser in Atrophic Acne Scars.

Introduction: Atrophic acne scarring, a common sequela of acne, can be treated by different interventions, including microneedling and laser resurfacing.

Objectives: We sought to evaluate the comparative efficacy of microneedling versus fractional CO2 laser in treating atrophic acne facial scars using imaging with high and ultra-high frequency ultrasound.

Methods: Participants received 2 sessions, separated by 1 month, of microneedling on the left side of the face and fractional CO2 laser on the right.

Post-Treatment Displacement of Facial Soft Tissue Fillers-A Retrospective Ultrasound-based Investigation of 382 Zygomatic Regions.

Background: Clinical and ultrasound experience has revealed that after soft tissue injections of the lateral cheek, the filler may displace from the zygoma to the caudal temporal area.

Objective: To obtain more data to provide insight into product distribution when soft tissue fillers are injected in the zygomatic region.

Methods: Two hundred patients were examined with facial ultrasound imaging of the zygomatic and temporal region.

Ultrasound Patterns of Vitiligo at High Frequency and Ultra-High Frequency.

Objectives: To detect ultrasonographic anatomical alterations in all the skin layers in patients with vitiligo.

Methods: A prospective observational color Doppler ultrasound study was performed in nonsegmental face and/or neck vitiligo patients without a history of previous treatments. Two sites, a lesional area and a contralateral clinically healthy region, were ultrasonographically studied and compared in the same patient.

Pre-operative high-frequency ultrasound: a reliable management tool in auricular and nasal non-melanoma skin cancer.

Background And Objectives: The knowledge of depth infiltration in non-melanoma skin cancer (NMSC) using pre-operative ultrasound could enable clinicians to choose the most adequate therapeutic approach, avoiding unnecessary surgeries and expensive imaging methods, delaying diagnosis and treatment. Our single-center retrospective study determined the usefulness of high-frequency ultrasound (HFUS) for depth infiltration assessment in auricular and nasal NMSC and assessed the subsequent change in therapeutic approach.

Patients And Methods: In 60 NMSC cases, we assessed the accuracy of HFUS in cartilaginous/bone infiltration detection as well as the correlation of sonographic and histological parameters.

Ultrasound Features of Nail Lichen Planus.

Objectives: To describe the ultrasonographic features of nail lichen planus (NLP), which, so far, have not been reported in the literature.

Methods: A retrospective single-center study of NLP patients' color Doppler ultrasound examinations was performed between March 2014 and January 2023. Inclusion criteria were patients ≥15 years with a confirmed clinical diagnosis of NLP in sequential order.

Ultrasound in Aesthetics: Filler and Non-Filler Applications.

Ultrasound in aesthetics presents multiple applications in several areas, including diagnosing fillers and non-fillers complications, the performance of ultrasound-guided injections in real-time, and identifying the most common types of cosmetic fillers. Furthermore, this application of ultrasound in aesthetics has become a must for managing aesthetic patients because, to date, this modality is the one that provides the higher resolution among imaging techniques, detailed anatomical information, and blood flow detection, besides showing worldwide availability. This paper aims to review the current applications of ultrasound in aesthetics based on publications from scientific literature and the authors' experience.

Ultrasound of Benign Cutaneous Tumors and Pseudotumors: The Key Lesions.

Benign cutaneous tumors are commonly seen in daily practice. Most of these lesions are diagnosed based on clinical appearance, but in some cases, clinical findings are nonspecific. A diagnostic imaging exam is indicated to provide additional information, and the first choice for studying dermatologic lesions is a high-frequency color Doppler ultrasound, a noninvasive technique that can play a relevant role in all cases and give important anatomical information for final diagnosis and proper clinical management.

Ultrasound of Nails: Why, How, When.

Nail disorders are frequently a challenge to diagnose correctly only based on clinical findings. Moreover, biopsies may leave scars due to damage to the nail matrix. Currently, high-frequency ultrasound (HFUS) with probes >15 MHz is the first-choice imaging technique to study the nail.

How to Start on Dermatologic Ultrasound: Basic Anatomical Concepts, Guidelines, Technical Considerations, and Best Tips.

Dermatologic ultrasound has grown exponentially during the last decades and has passed from the experimental phase to the routine daily practice in multiple countries. The performance of this imaging technique requires color Doppler ultrasound devices working with high-frequency probes, a trained operator on imaging and dermatologic conditions, and the performance of standardized protocols for obtaining the anatomical data properly. In this review, we analyze the ultrasonographic anatomy of the skin, hair, and nails, the technical requirements and considerations, the guidelines, and the recommended protocols, and provide the best tips for practicing this type of examination confidently.

Role of Color Doppler Ultrasound in Cutaneous Inflammatory Conditions.

Inflammatory cutaneous diseases can be challenging to diagnose and manage. Nowadays, the anatomical information provided by ultrasound is critical for detecting subclinical alterations and assessing the severity and activity of these conditions. Many of these entities can be clinically observed in dermatology and other specialties, such as rheumatology, plastic surgery, ophthalmology, and otolaryngology, among others.
