Treatment of vascular lesions located in the lip and in the oral cavity with Nd:YAG laser.

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.

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.

Recalcitrant Sterile Abscesses by Volux®: A New Therapeutic Approach.

The number of patients developing sterile abscesses because of hyaluronic acid (HA) filler procedures has increased for unknown reasons. We described this adverse reaction after filling with Juvederm Volux®, the latest innovative product in the Vycross range of technology. We presented five patients with recalcitrant sterile abscesses after filling with Juvederm Volux® who did not respond to the traditional therapy but whose lesions were resolved with the "Munhoz-Cavallieri lavage protocol" developed and recently published by the present authors. (SKINmed. 2023;21:27-33).

Subungual squamous cell carcinoma.

Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or viral wart. These factors, together with a general lack of awareness of this disease among physicians, often result in delayed diagnosis. Therefore, it is underdiagnosed, with few reports in the literature. The authors present a case of a man with a diagnosis of subungual squamous cell carcinoma in the hallux, without bone involvement, which was submitted to the appropriate surgical treatment.

Basal cell nevus syndrome: clinical and molecular review and case report.

Basal cell nevus syndrome (BCNS), also referred to as nevoid basal cell carcinoma syndrome or Gorlin-Goltz syndrome, was first described by Gorlin and Goltz in 1960 as an autosomal dominant disorder characterized by the early appearance of multiple basal cell carcinomas (BCCs), keratocysts of the jaw, ectopic calcifications, palmar and plantar pits, and anomalies of the ocular, skeletal, and reproductive systems. The genesis of this cancer's etiology in relation to BCNS was unclear until a few years ago when molecular analysis studies suggested a relationship between BCC and the loss-of-function mutations of the patched gene (PTCH) found on chromosome arm 9q. PTCH inhibits signaling by the membrane protein Smoothened (Smo), and this inhibition is relieved by binding sonic hedgehog (SHH) to PTCH. We describe a patient with multiple BCCs associated with x-ray anomalies of BCNS and review the basis of the SHH signaling pathway and clinical aspects of BCNS.

Edema tardio intermitente e persistente ETIP: reação adversa tardia ao preenchedor de ácido hialurônico / Persistent, Intermitent Delayed Swelling PIDS: late adverse reaction to Hyaluronic Acid fillers

Introdução: O uso do ácido hialurônico para correções estéticas cresceu exponencialmente nos últimos anos. O ultrassom de pele mostra-se método eficaz para identificação do preenchedor e suas complicações. Um tipo particular de efeito adverso, caracterizado por edema tardio e persistente, de caráter intermitente, vem sendo observado ultimamente. Objetivo: Caracterizar uma complicação tardia após preenchimento facial com ácido hialurônico. Métodos: Selecionaram-se exames de ultrassom da pele realizados em clínica privada de outubro de 2016 a julho de 2017, encaminhados para avaliação de complicação após preenchedores. Questionários foram enviados aos médicos solicitantes para coleta de dados clínicos. Resultados: Em 108 exames foram identificados 33 casos de edema local associado à presença de ácido hialurônico. Episódios de edema foram referidos como recorrentes, na área previamente afetada ou em outro sítio de injeção. Conclusão: Os autores propõem nomenclatura específica: edema tardio intermitente e persistente para agrupar as reações adversas tardias ao ácido hialurônico, que se traduzem por edema local tardio, de caráter intermitente, deflagrado por gatilhos específicos e que persiste enquanto houver a presença do ácido hialurônico no tecido.

Introduction: The use of hyaluronic acid fillers (HA) for esthetic corrections has exponentially grown in recent years. Skin ultrasound (US) is an effective method to identify the filler and its complications. A particular type of adverse effect, characterized by late, persistent edema of an intermittent nature, has been lately observed. Objective: To describe a delayed complication due to easy HA fillers, named by the authors as Persistent, Intermitent Delayed Swelling (PIDS). Methods: From October 2016 to July 2017, US examinations performed at Cavallieri Clinic were selected and referred for evaluation of post-filler complications. Questionnaires were sent to requesting physicians for clinical data collection. Results: Of 108 exams, 33 cases of local subcutaneous edema associated with the presence of HA fillers were identified. Episodes of edema were referred to as recurrent, in the previously affected area, or at another injection site. Conclusion: The authors propose a specific nomenclature: PIDS to refer to this late adverse reaction to HA fillers, which includes delayed and intermittent local swelling, triggered by specific conditions, that persists for as long the HA remains in the subcutaneous tissue.

Fitofotodermatite por Ruta graveolens com manifestação cutânea extensa / Phytophotodermatitis due to Ruta graveolens with extensive cutaneous manifestation

Dermatite de contato por planta ou fitodermatite é uma erupção cutânea resultante do contato com substâncias produzidas por diferentes espécies de vegetais. Ruta graveolens, popularmente conhecida como arruda, é uma planta da família das Rutaceae, que inclui algumas frutas cítricas, e contém inúmeras substâncias químicas fotossensíveis, incluindo os furocumarínicos. Relatamos um caso de reação de fitofototoxicidade grave em uma paciente que usou uma infusão de arruda pelas supostas qualidades ”místicas e purificadoras” da planta com extensa erupção cutânea.

Plant dermatitis or phytodermatitis is a cutaneous eruption resulting from contact with substances produced by different plant species. Ruta graveolens, popular known as common rue, is an herbal plant from the Rutaceae family, which includes the citrus fruits, and contains numerous photosensitizing substances, including furocoumarins. We report a severe case of phytophototoxicity reaction in a patient who used a common rue infusion because of its “powerful and purification” qualities.
