Introduction: Intense pulsed light is commonly used for hair removal. Corticosteroids of low or medium potency are generally employed for pain and inflammatory reaction relief following such procedures. Botanical compounds, such as andiroba oil emulsion, have been proven to have moisturizing and anti-inflammatory effects. Objective: To compare the effectiveness of andiroba oil emulsion to desonide as an option to topical corticosteroids. Methods: A prospective, comparative, double-blind study evaluated nine female patients who underwent air removal with intense pulsed light in the inguinal region. The patients were treated immediately after the procedure with desonide on one side and andiroba oil emulsion on the other. The patients rated the pain sensation using a visual analog pain scale, and an observer dermatologist physician evaluated the inflammatory reaction caused by the procedure, comparing the two sides blindly. Results: There were no significant differences in pain relief or inflammation between the two products. The analgesic and anti-inflammatory potential of andiroba oil emulsion practically equaled that of desonide. Conclusions: This pilot study''''''''s results indicate that andiroba oil emulsion can be a treatment option following photoepilation.

The authors describe the case of a 75-year-old female patient, bearing a single asymptomatic, nodular lesion of fibroelastic consistency for three years, located on the left hallux. Following surgical excision of the lesion, the pathological examination and immunohistochemistry revealed a superficial acral fibromyxoma. This type of lesion was first described in 2001 and today there are approximately 100 cases in the literature. It is a benign mesenchymal tumor of slow growth, with a predilection for ungual and peri-ungual regions. There are no reports of malignant transformation and recurrence has been associated with incomplete resection.

Melanonychia corresponds to color patterns in the nail plate, ranging from brown to black. It is a diagnostic challenge due to the fact it has several differential diagnoses, including benign and malignant entities. There are no reports of pigmented fibroma of the nail matrix causing striata (or longitudinal) melanonychia. In light of this fact, the authors report a case of melanonychia striata secondary to pigmented fibroma of the nail, with clinical examination and dermoscopic findings suggestive of nodular melanoma.

Pachydermodactyly is a rare, benign and acquired form of digital fibromatosis characterized by the thickening of soft tissues in the lateral regions of the proximal interphalangeal joints, typically of the digiti II, III and IV of both hands. In most cases it is associated with repeated digital microtraumas. The authors of the present article report the case of a 22-year-old patient with a typical clinical presentation of the condition. The treatment with triamcinolone injections led to a partial reduction of the thickening, in addition to hypopigmentation and hyperemia, meaning it was an unfavorable option. Although rare and benign, this typical clinical condition deserves attention, and unnecessary and costly investigations, as well as inappropriate treatments should be avoided.

Introduction: Signs of aging usually arise more intensely on the face, neck, and hands, in the form of considerable loss of volume, which is a common indicator of aging.
Objective: To compare the duration, and adverse effects of two types of subcutaneous fillers in the treatment of the volumetric aging of hands.
Methods: Group A: four patients who used the same amount of the products in both hands; Group B: four patients who used greater amounts of calcium hydroxyapatite in one of the hands and Group C: four patients who used greater amounts of hyaluronic acid also in one of the hands. The patients were evaluated through changes in a validated scale for hand aging, recorded by digital photographs before and 1,3,6,9,12,15 and 18 months after the procedure.
Results: In Group A the patients had the same duration for both fillers; in Group B patients treated with hydroxyapatite calcium had longer duration; in Group C, the patients treated with hyaluronic acid presented longer duration. Adverse effects were more frequent with the use of calcium hydroxyapatite.
Conclusions: It can be concluded that the filler duration is proportional to the volume injected for both fillers, and that hyaluronic acid is safer for the treatment of this cosmetic irregularity.

INTRODUCTION: Acrochordons are very prevalent in dermatological offices and can reach almost 60% of the population over 70. One possible therapeutic approach is contact cryotherapy.
OBJECTIVES: Compare pain tolerance, aesthetic results, and the preference of participants for electrocoagulation or contact cryotherapy techniques in the treatment of acrochordons.
METHODS: Ten participants, with at least four acrochordons each, had their lesions divided into two groups. One group was submitted to electrocoagulation and the other to contact cryotherapy. We measured pain tolerance using the analog pain scale (EAD). The aesthetic result was assessed by visual comparison between the treatment groups in each participant, and the patient’s preference was evaluated by asking the participant objectively.
RESULTS: All points analyzed had statistical significance. The participants gave lower scores in EAD for lesions submitted to contact cryotherapy. The esthetic result evaluated after 30 days was superior in the lesions of the electrocoagulation group. All participants preferred the contact cryotherapy technique.
CONCLUSIONS: Contact cryotherapy is the preferred method with better pain tolerance in treating acrochordons, but the aesthetic result was better with electrocoagulation.

Nodular fasciitis is a benign tumor resulting from the reactive proliferation of fibroblastic or myofibroblastic cells presenting rapid growth and rich cellularity. In adults, the extremities’ involvement is more frequent; however, other regions can be affected. In this report, we present the case of a 40-year-old woman with a nodular lesion on the forehead. The histopathology confirmed the diagnosis of nodular fasciitis. The reported case highlights its rare location and alerts the clinical dermatologist in its inclusion among the differential diagnoses of tumor lesions on the face.

Koenen tumors are nail fibromas included among the main diagnostic criteria of tuberous sclerosis. Elongated and thin papules, firm, with smooth surface and broad base characterize these lesions, which are slightly erythematous and present varying sizes. Koenen tumors commonly affect toenails and result in aesthetic and functional concerns associated with deformities, pain, and bleeding. Several therapeutic options are described for Koenen tumors; however, there is a lack of consensus in the literature regarding standard treatment. We report the case of a patient who underwent surgery with excellent outcomes. Additionally, we discuss the advantages and disadvantages of each therapeutic modality.

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.

The trichogram is an easy and semi-invasive method, useful for evaluating different types of hair loss in daily practice. To date, there is no standardized methodology on how to collect and perform the exam. The use of a liquid interface between the slide and the coverslip to read the trichogram under optical microscopy varies widely in the literature. Among the alternatives, transparent enamel base coat is an inexpensive, accessible, and practical option, providing the examiner with proper visualization of the hair shafts with minimal air bubbles formation.
