Minor salivary gland biopsy is essential for the diagnosis of Sjögren’s syndrome. The authors demonstrate the use of chalazion clamp to facilitate this procedure. Chalazion clamp retains the lip mucosal bleeding and exposes the salivary glands more easily for their dissection and excision individually, which facilitates the removal of various glands to histopathological examination.

Introduction: The beauty industry in Brazil ranks third in the world by size, second only to those of the U.S. and Japan. Paradoxically, the vast majority of studies on aesthetic treatments for the skin do not demonstrate a corresponding knowledge of the industry by the relevant population. Contemporary women, with their increasingly strong role in society, are the engine that drives the growth of the beauty and aesthetics industry. Objectives: To obtain data related to the population's knowledge of cosmetic dermatology treatments. Methods: A descriptive, multicentric study was carried out in the Brazilian states of São Paulo, Rio de Janeiro, and Santa Catarina with 600 women between the ages of 18 and 70 years old. Results: The majority of the target population wants to correct skin imperfections, however there is great suspicion about the effectiveness of the treatments available. The dermatologist's practice is not the main source of information for the interested audience. Conclusions: The consumer profile in the beauty market undergoes constant changes and to understand the public's knowledge, concerns, and challenges linked to these issues is key to allowing discussion with, and educating patients about the ever-expanding cosmetic dermatology field.

INTRODUCTION: Dermatobia hominis is one of the main etiologic agents of furunculoid myiasis. It is more common in intertropical countries and induces the formation of a papule or nodule in the skin with a central orifice. When the lesion's diagnosis is not made or when the larva does not go out, it can progress to the formation of a tumor. We report a rare case of a lipoma-simulating lesion in the lower limb of a man living in the countryside. The etiological diagnosis was made exclusively through histopathological examination, which showed a cyst with exogenous material to the center, compatible with D. hominis, in a clear degradation process.

Blue nevus is a benign lesion arising from dermal melanocytes containing large amounts of melanin. The agminated variant presents a cluster of blue nevus lesions with linear or blaschkoid distribution. We report two cases of patients with agminated blue nevus that developed on previous acne scars, and dermoscopy helped a lot in the differential diagnosis. This is the first occurrence found in the literature of agminated blue nevus that appeared on a previous scar, which may have occurred by chance or as a result of the collagen remodeling process inherent to the healing process.

We report a case of a 72-year-old man who underwent surgical excision of a keratoacanthoma centrifugum marginatum (KCM) located on the left forearm. It is an uncommon variant of keratoacanthoma, which can assume large dimensions (up to 20 cm) and does not tend to spontaneous regression. The lesion is usually single, with raised borders, and has progressive centrifugal growth associated with central healing and atrophy. Due to its rarity and lack of pathognomonic histopathological features, KCM can be a diagnostic challenge for dermatologists and pathologists.
