Lip cancer corresponds to 25-35% of all oral cancers. Squamous cell carcinoma is the most common histological type in this location (95%). Various wound reconstruction options are described for the exeresis of this type of tumor in the lower lip - the choice depending on the surgeon's experience and the proportion of the final defect regarding the dimensions of the lip. The present article describes the case of a male patient with a wound in the lower lip that was histologically diagnosed as an invasive squamous cell carcinoma. Mohs surgery was implemented and a transposition flap (Abbé flap) was used in the reconstruction of the upper lip. The complete opening of the mouth, without functional impairment of the speech or chewing function, and a favorable aesthetic result, were observed in the follow-up, thus demonstrating the usefulness of this type of reconstruction.

Pyogenic granuloma or lobular capillary hemangioma is a benign skin and mucous membranes lesion whose etiology is not yet explained. The authors report an atypical and exuberant clinical case of this benign dermatologic condition, clinically simulating malignancy.

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.

Lower lip squamous cell carcinomas (SCC) correspond to 20-30% of all oral cavity cancers. It mainly affects men over 50 years of age who have previous history of smoking, alcoholism and exposure to the sunlight. The diagnosis is clinical, confirmed by histological analysis. The present paper describes a case of a patient with a SCC affecting more than 1/3 of the lower lip, who underwent resection of the primary lesion and a conservative reconstruction of the lesion’s region, due to the great local mobility, aimed at preserving the functionality without compromising the aesthetic outcome.

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.

Cutaneous defects of the lower eyelid frequently require reconstructions with grafts or flaps to avoid ectropion. Removal of a basal cell carcinoma from the lower eyelid of a 39-year-old patient resulted in an exclusively cutaneous defect, with transversal and vertical diameters of 32 and 13mm, respectively. Despite the large size of the defect, the elevation of the suborbicularis oculi fascia to the periosteum of the lateral orbital border made primary closure possible. The position of the lower was also reinforced with a lateral canthopexy, with excellent aesthetic and functional results.

The cutaneous field cancerization corresponds to an area of skin chronically exposed to the sun. It contains actinic keratoses and other skin signs of photodamage caused by ultraviolet radiation. This field comprises the genetic alterations that form the basis of the process of cutaneous carcinogenesis. Actinic keratoses have the potential to be stable for years, to regress spontaneously or to become invasive carcinomas. There is a consensus in the literature that the treatment of the entire field cancerization is more effective than treating just isolated lesions since it is not possible to predict which of these lesions will evolve to invasive cancer. It is also effective in the prophylaxis and treatment of the existing clinically imperceptible incipient lesions. There are several therapeutic options for individualized actinic keratoses and the field cancerization, from self-applied topical drug therapies to interventional and surgical therapies.

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.
