Sonography of monkeypox cutaneous lesions.

The present global outbreak of monkeypox has reached more than 79,000 cases by November 2022. While clinical features have been extensively studied, ultrasound findings in monkeypox skin lesions have not been described to date. In our work, we performed a complete sonographic study with Doppler and elastography of 3 patients with polymerase chain reaction-proven monkeypox. The most characteristic findings in skin lesions were hyperechoic epidermal thickening, dermo-hypodermal thickening with focal hypoechogenicity and increased intralesional vascularization. Regarding lymphadenopathies, we found vascularization of hilar distribution and an increased cortical stiffness and shoft hiliar area.

Cell Blocks from Ultrasound Guided Fine Needle Aspirates: Diagnostic Yield in a Series of 51 Dermatologic Lesions / Bloques celulares obtenidos de la punción-aspiración con aguja fina ecoguiada: rendimiento diagnóstico en una serie de 51 lesiones dermatológicas

The generation of cell blocks (CB) obtained from ultrasound-guided fine needle aspiration biopsies (USFNAB) is a well-established technique in breast and thyroid pathology, but is rarely used in dermatology. We reviewed CBs obtained from USFNAB of skin lesions, which were categorized as malignant skin tumors, benign skin tumors, inflammatory skin tumors or deposit skin diseases. The diagnostic yield of each category was compared to histopathology. The USFNAB of 51 skin lesions was processed into CBs. There was overall agreement between histopathology and CBs in 84.31% of cases. Diagnostic group concordance for benign, malignant as well as inflammatory and deposit skin lesions were 69.2%, 93.7% and 86.3% respectively. Cell block generation from USFNAB aspirates of skin lesions should be considered as part of the dermatologic diagnostic armamentarium. Further experience is needed to better understand for which types of dermatologic lesions it would be clearly indicated (AU)

La generación de bloques celulares (CBs) obtenidos a partir de punción-aspiración con aguja fina guiada por ultrasonido (USFNAB), es una técnica bien establecida en patología mamaria y tiroidea, pero rara vez se utiliza en dermatología. Revisamos los CBs obtenidos por USFNAB de lesiones cutáneas, que se clasificaron como tumores cutáneos malignos, tumores cutáneos benignos, tumores cutáneos inflamatorios o enfermedades cutáneas por depósito. El rendimiento diagnóstico de cada categoría se comparó con la histopatología. La USFNAB de 51 lesiones cutáneas se procesó en CBs. Hubo concordancia global entre la histopatología y los CBs en el 84,31% de los casos. La concordancia entre histopatología y CBs para lesiones cutáneas benignas, malignas e inflamatorias y por depósito fue del 69,2, 93,7 y 86,3%, respectivamente. La generación de CBs a partir de USFNAB de lesiones cutáneas debe considerarse como parte del arsenal diagnóstico dermatológico. Se necesita más experiencia para comprender mejor para qué tipos de lesiones dermatológicas estaría claramente recomendado (AU)

Sonographic findings in scabies.

Scabies is a cutaneous infestation caused by Sarcoptes scabiei var. hominis, a small mite that performs its whole life cycle within the epidermis. In this case report, we provide images of the sonographic signs of scabies. We found that the adult mite can be seen as a hyperechoic well-defined ovoid area within the epidermal layer at the end of the hypoechoic burrow, while the eggs correspond to tiny heteroechoic dots along the burrow. In conclusion, ultrasound may prove useful to differentiate between inhabited vs non-inhabited scabiotic burrows.

Intralesional corticosteroid injection for the treatment of hidradenitis suppurativa: a multicenter retrospective clinical study.

BACKGROUND AND OBJECTIVES: Hidradenitis suppurativa (HS) is a chronic inflammatory disease of the follicular unit characterized by recurrent, painful, skin lesions including inflammatory nodules, abscesses, tunnels, and mutilating scarring. Intralesional corticosteroids injection (ICI) for HS has received little attention in the scientific literature. We evaluate the clinical response of ICI in acute and chronic HS lesions and aim to identify new applications of ultrasound-assisted procedures in HS management. PATIENTS AND METHODS: An observational, retrospective, multicenter study of HS patients treated with ICI was conducted from January 1 to August 1, 2015. We collected 98 HS patients. A total of 135 individual lesions were infiltrated, including non-inflammatory nodules, inflammatory nodules abscesses and fistulous tracts. RESULTS: Complete response was reached in 95 lesions (70.37%), 34 showed partial response (25.19%) and 6 (4.44%) were non-response. A total of 105 individual lesions underwent sonographic scan before ICI. CONCLUSION: Clinical experience supported the use of ICI for individual lesions. Our results showed that ICI is a useful treatment to control in acute and recalcitrant HS lesions. Response rates improve significantly if lesions are previously evaluated with HFUS.

Usefulness of ultrasound for treatment and follow-up of cutaneous leishmaniasis.

PURPOSE: Local therapy is the preferred option of treatment for most cutaneous leishmaniasis (CL); however, local therapy could be challenging, depth and size of the skin lesions are not always clinically evident and treatment response evaluation could occasionally be misleading. High frequency ultrasound is a non-invasive imaging tool which allows initial depth assessment ultrasound-guided infiltrations and ultrasound monitoring until resolution. METHODS: We present two cases of CL treated with ultrasound-guided infiltrations and ultrasound monitoring until resolution. RESULTS: Ultrasound imaging allowed a more accurate diagnosis of CL, defining more precisely the depth and size of the skin lesions. During follow-up, progressive decrease in dermal involvement, marked attenuation of the echogenicity of subcutaneous cellular tissue and a decrease in vascularization in the color Doppler mode was observed, which aided in evaluation of treatment response. Hypodermal inflammation observed through sonography was addressed with image-guided infiltration. CONCLUSION: We would like to highlight the usefulness of skin ultrasound (both B-mode and color Doppler mode) in the diagnosis, depth assessment, imaging guided treatment, and follow-up in CL.
