Introduction: Androgenic alopecia is a progressive alteration of the scalp with few treatment options, which motivates the search for new local or systemic medications to control this pathology.
Objective: To evaluate patient tolerance for and identify the action mechanism of the Cellium® GC compound in the treatment of androgenic alopecia.
Methods: Male patients (n = 20) with androgenic alopecia participated in this open prospective study. The compound was used on the scalp twice a day, at home, for 12 con- secutive weeks. Biopsies were carried out before and after treatment to evaluate the alterations in the cutaneous immune response, cellular proliferation and anti-apoptosis activity. Questionnaires were administered to evaluate efficacy and patient satisfaction.
Results: Nineteen patients completed the study, with an average satisfaction of 8.3 out of 10. Immunohistochemical analyses of scalp biopsies showed a significant increase in the cutaneous immune response after treatment: 73.9% increase in CD1A+ Langerhans cells (p = 0.003, t paired test), 41.7% increase in the cellular proliferation marker Ki-67+ (p = 0.012), and an 89% increase in BCL-2+ anti apoptotic proteins (p = 001). The product was also found to be tolerable and safe.
Conclusions: Cellium® GC improved the skin''''''''s immune defense and the proliferation of keratinocytes, and produced high levels of patient satisfaction in the treatment of androgenic alopecia.

In hair transplants, the donor area can supply only a limited number of follicular units in each procedure. In the treatment of more advanced degrees of baldness, removing both a scalp strip and follicular units, one by one, is an option that allows more units to be harvested in a single session, thus providing a better density and coverage of the bald area. This article describes a technique called Untouched Strip, which, in addition to increasing the number of follicular units with the combined procedure, preserves the donor area for a possible future transplant.

Introduction: Telogen effluvium is a chronic progressive alopecia of multifactorial etiology. Nutritional deficiency-sometimes subclinical-can trigger it. Objective: To evaluate the influence of a nutritional supplementation at physiological doses in patients with telogen effluvium. Methods: The supplementation of nutrients in food doses was carried out in 60 female patients for 180 days. Results: There was a significant improvement (p <0.05) in hair loss, which was confirmed by digital phototrichogram, where there was a significant increase in anagen hairs and reduction of telogen hairs. Conclusion: The present study demonstrated that in cases of telogen effluvium without an apparent cause, the replenishment of nutrients related to the hair cycle has a significant benefit in the regression of the picture as soon as after three months of treatment.

Androgenetic alopecia is a condition with an important psychological impact. Clinical treatments present variable responses and require care for long periods, a factor that decreases the chances of adhesion. Microneedling with or without minoxidil injection is a new treatment modality. This study reports cases of two male patients, aged 30 and 44 years, with satisfactory partial response to four sessions of microneedling with minoxidil and three sessions of microneedling alone, using a tattoo machine and microinfusion of drugs into the skin technique.

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.

Alopecia areata is a chronic condition of hair follicles and nails with unknown etiology, which causes hair loss. It emerges in several clinical types, with the diffuse form, where there is acute and diffuse hair loss, being atypical. It is generally accepted that there is a T-cell mediated, organ-specific autoimmune base in alopecia areata and studies indicate that the autoantigen is associated with melanocytes. The authors of the present paper report the case of a patient who had the diffuse form of alopecia areata, with preservation of the gray hair strands

The association of cysts and comedones in chronically sun-damaged skin characterizes the Favre-Racouchot syndrome. The authors report a case of a 64 year-old male patient with a history of smoking and tillage work activity. The patient had lesions in the malar, zygomatic and mandibular regions bilaterally, constituted by slightly erythematous cysts and large comedones in thickened skin with deep grooves. The condition was diagnosed as Favre-Racouchot syndrome, and treated by means of surgical excision. The objective of the present study is to describe an exuberant presentation of the syndrome, and its treatment via surgical excision.

Cysts are benign epithelial tumors widespread. The trichilemmal cysts, originating from the anagen’s isthmus, represent about 20% of the cysts and are located more frequently in the scalp (90%). Several methods can be used for the removal of the cysts. The choice of technique depends on its characteristics, such as size, mobility, consistency, quiescence, inflammation, and quantity. However, they may grow again if the capsule is incomplete removed. The authors present a simple variant of the marsupialization technique that allows its complete removal.

The giant BCC is a rare variant, and the repair of large defects in the scalp, generated after oncologic resection, is a surgical challenge. We report the case of a patient submitted to late scalp reconstruction after oncologic resection of giant BCC in the scalp with the association of techniques. Reconstruction of scalp lesions depends on a comprehensive understanding of the anatomy of this site, knowledge of the arsenal of surgical techniques, and a detailed assessment of patient factors and expectations, given the impact on the quality of life and morbidity related to each therapeutic option.

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.

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.

BACKGROUND: Reconstructive surgery remains the primary approach for treating facial skin cancer, aiming to restore both anatomy and aesthetics. Local flaps are commonly preferred for facial reconstruction.
OBJECTIVE: To describe the clinical and subclinical characteristics of facial skin cancer and evaluate treatment outcomes using local flaps.
METHODS: A descriptive cross-sectional study with clinical intervention, without a control group, was conducted on 84 patients diagnosed with facial skin cancer and treated at Can Tho City Oncology Hospital from May 2021 to April 2023.
RESULTS: Outcomes were assessed during hospitalization and 6 months postoperatively. Among the 84 patients, 68 had basal cell carcinoma, and 16 had squamous cell carcinoma. The nose was the most frequently treated site, accounting for 43 cases. Lesions smaller than 2 cm comprised 70.2% of cases. After 6 months, 65 out of 84 flap sites (77.4%) exhibited minimal scarring that could be concealed, with an aesthetic success rate of 73.8%.
CONCLUSIONS: Key factors influencing surgical outcomes include the surgeon's experience, lesion location and size, tumor invasion extent, and skin elasticity.
