Angiolymphoid hyperplasia with eosinophilia is a rare and benign vascular tumor whose etiology remains uncertain. It clinically presents itself by angiomatous papules or nodules located on the head and neck. Many controversies in the literature are found in relation to angiolymphoid hyperplasia with eosinophilia and Kimura's disease - its main differential diagnosis - due to their clinical and histopathological similarities. However, currently, most studies agree that they are distinct diseases. The present case illustrates a characteristic description of angiolymphoid hyperplasia with eosinophilia and also highlights the main differences with Kimura's disease.

Aesthetic treatment with hyaluronic acid (HA)-based fillers has shown a growing demand and becoming a choice as an option in minimally invasive rejuvenation, either as a volumizer in cases of tissue loss, facial contouring with definition or correction of rhytids. 1,2 As the HA injections had increased, the reports of adverse events related to it also raised. The first-line treatment of these undesirable effects is hyaluronidase (HYAL). 3,4 HYAL is a natural enzyme that degrades hyaluronic acid and can be used in the management of the majority of adverse events related to the use of this filler, such as overcorrections like nodules and bumps, Tyndall effect or late nodules, and even more severe complications as tissue ischemia. 1,5 This study aims to describe the safety and effectiveness of the use of HYAL in the correction of undesirable results of hyaluronic acid fillers in 114 patients in private dermatologic practice. | MATERIAL S AND ME THODSA retrospective study of 114 patients submitted to the application of HYAL (hyaluronidase 2.000 UI, BIOMETIL tm ) was performed to correct unaesthetic effects after filler injections on the face. Cases were selected from a private clinic from June 2015 to November 2018 by reviewing charts and analyzing photographic documentation, and the following data were evaluated: age, gender, the indication of use, the anatomical unit involved, number of sessions, amount of HYAL used, and adverse effects after the application of

Vascular lesions such as hemangiomas can be found in the oral cavity. Some therapeutic modalities can be used in the treatment of these lesions and Nd:YAG 1064 nm long pulse laser shows good results with easy application, fewer complications and satisfactory results. This study describes the technique and outcome of a case of hemangioma located on the tongue treated with Nd:YAG laser.

Background: An increasing demand of minimally-invasive aesthetic procedures of the forehead concomitantly leads to higher numbers of adverse events. Adequate application of anatomical knowledge is required to increase safety and efficacy of different minimally-invasive aesthetic procedures in this anatomical region.Objective: To describe the layered anatomy of the forehead soft tissues with respect to their thicknesses and how they relate to different minimally-invasive aesthetic treatments.Methods: A total of n = 85 healthy study participants (69 females and 16 males) with a mean age of 40.84 ± 10.9 years and a mean body mass index of 22.65 ± 2.6 kg/m 2 were investigated with ultrasound-based imaging to measure the thickness of different forehead soft tissues. Results:The mean overall soft tissue thickness of the forehead was measured to be 4.18 ± 0.7 mm for the entire study population. Increasing BMI values correlated statistically significantly with increasing thickness of all measured forehead soft tissues with exception of the frontalis muscle. On a statistically significant level, males showed thicker forehead soft tissues than females, with exception of the retrofrontalis fat and the frontalis muscle. Conclusion:On basis of the findings obtained in this study, basic treatment principles can be derived and improved for the injection of neuromodulators, hyaluronic acid as well as the application of polydiaxonane (PDO) threads and micro-focused ultrasound.Precise knowledge and thorough understanding of the layers and soft tissues of the forehead is required to guarantee safe and effective procedures in this aesthetically important facial region.

Background The young face presents a more convex and rounded aspect, while through the years, a more concave and flattened aspect happens to be exteriorized. In this context of aging, the angles of the face are undergoing changes through soft tissue repositioning and bone remodeling. The columellar-labial angle is one of those changes, so that is why we are studying it further Objectives The objective of the present study is to analyze the columellar labial angle during the stages of adult life and its contribution to the face´s modification in the ageing process. Methods To this study, we analyzed a database (December 2017 to March 2018) of 722 female patients, aged 21-88 years, for the anthropometric measurement of the columellar labial angle, through the program Vectra 3D (Canfield) photo analysis program. Our database originates from the private clinic where all patients have registration and photography. Results Through the analysis of the patients, we obtained as a result a decrease in the value of the columellar labial angle, mainly observed from the patients 60 years upwards. The decrease of this angle can be explained, for example, by the absorption of body structures that occurs during ageing. Conclusions We concluded that the columellar labial angle decreases with age, a fact that may give a better understanding of the transformation of the course of ageing. This understanding allows us to have a clearer view of the changes that occur in the face, improving the treatments for facial rejuvenation, either conservative or surgical, and provide a basis for future studies and knowledge expansion.
