“…1 , 3 ). Most of the scalp hair is trilaminar, and the bilaminar hair tracts, also called villus hairs, are present in the scalp to a greater extent than in the rest of the body [ 10 , 11 , 14 ]. The predominance of villus (bilaminar) over trilaminar hair tracts in the scalp has been reported in certain types of alopecia, such as androgenetic alopecia [ 15 ].…”

“…On color Doppler, it is possible to detect low-velocity vessels (≤15 cm/s) with arterial and venous blood flow in the subcutaneous tissue and very few vessels in the dermis. This is due to the current sensitivity of machines, which can usually detect flow ≥2 cm/s; therefore, currently, the blood flow within the normal dermal vessels is difficult to detect on ultrasonography [ 10 , 11 ].…”

Dermatologic ultrasound is a new field of ultrasonography that has been growing exponentially in the last ten years. It has multiple applications that can modify patient management such as benign and malignant cutaneous tumors, vascular anomalies, inflammatory dermatologic entities, aesthetic complications, and nail lesions.Compared with other imaging techniques such as CT or MRI, ultrasound has the highest axial spatial resolution and has benefited from developing high and ultrahigh frequency probes that could even reach 70 MHz.The daily use of ultrasonography in dermatology has been reported to improve the accuracy of the diagnoses, the tracking of activity and the assessment of severity in common dermatologic conditions, which certainly can support a better treatment of the patients.

“…CTP HFUS findings are well-defined in B-mode and color Doppler [14]. In color Doppler mode, the systolic peak, resistance index, and the diameter of inflamed vessels can be measured [32]. In other skin diseases causing panniculitis, such as morphea or sclerodermiform graft-versus-host disease, color Doppler mode values have been established to define inflammation [12,13].…”

“…In Parry-Romberg syndrome, the usefulness of CT and MRI in measuring subcutaneous tissue atrophy was described [36]. However, these techniques are usually not as accessible as HFUS, are more expensive, uncomfortable for the patient, and may require the use of a contrast medium and, in the case of CT, ionizing radiation [32].…”

Determining disease activity from clinical signs in patients with connective tissue panniculitis (CTP) is often challenging but is essential for therapeutic decision making, which largely relies on immunosuppressant treatment. High-frequency ultrasound (HFUS) may be useful in supporting such decisions by accurately determining CTP activity. This study aimed to investigate the accuracy of HFUS in identifying signs of CTP activity or inactivity and assess its usefulness in therapeutic decision making. A prospective cohort study of consecutive patients with biopsy-proven CTP receiving HFUS was conducted in a tertiary university hospital (2016–2020). HFUS was performed at inclusion and at each 3- or 6-month follow-up visit, depending on disease activity. Twenty-three patients with CTP were included, and 134 HFUSs were performed. In 59.7% (80) of the evaluations, the clinical presentation did not show whether CTP was active or not. In these cases, HFUS showed activity in 38.7% (31) and inactivity in 61.3% (49). In 71.25% (57) of the visits, HFUS was the determinant for therapeutic decisions. Further follow-up showed consistent clinical and HFUS responses in all unclear cases after treatment modification. HFUS appears to be a useful adjunct to the clinical examination for CTP to assess activity and make therapeutic decisions.

The advances in dermatologic ultrasound have been significantly influenced by the development of high‐ and ultrahigh‐frequency probes, the provision of guidelines for performing the examinations, and a growing number of publications in the field. This review analyzes the most significant contributions that have impacted the daily practice of dermatologists in recent years. This includes the advances in anatomical detection and the patterns of benign and malignant cutaneous tumors, inflammatory dermatologic conditions, vascular anomalies, nail abnormalities, and aesthetic procedures. The knowledge of these advances is a primer for the operators of these examinations.
