INTRODUCTION: Onychomatricoma is a rare benign tumor characterized by a clinical tetrad of a yellowish longitudinal band of varying thickness, splinter hemorrhages, longitudinal and transverse hypercurvature of the nail plate, and digitiform projections emerging from the nail matrix, leaving cavitations in the nail plate. We report a case of a female patient, 49 years old, with a history of a tumoral lesion in the third left toe for about four years, with a progressive increase in this period. Physical examination revealed an exuberant tumor lesion clinically compatible with onychomatricoma, confirmed by pathological examination after complete tumor excision.

Although several techniques have been described for upper lip reconstruction, functional reconstruction of total upper lip defects remains a challenge. We report a case of a significant size squamous cell carcinoma excised in the upper lip region using the double-advancement technique, with positive functional and aesthetic results.

Squamous cell carcinoma (SCC) represents the second most common type of skin cancer. SCC originates from the atypical proliferation of the cells of the epidermis's spinous layer and is more frequent in men over 50 years of age, with a low skin phototype and history of sun exposure. We describe the case of a 61-year-old man, previously healthy, with a lesion presenting fast and exuberant growth on the face. The anatomopathological and immunohistochemical exams confirmed the diagnosis of moderately differentiated SCC.

Multiple adult xanthogranuloma is a rare and late variant of Juvenile xanthogranuloma, a non-Langerhans cell histiocytosis. It usually corresponds to a single lesion in adults, and the manifestation of multiples lesions is uncommon. We report a case of multiple adult xanthogranuloma, with Isotretinoin therapy failure and optimal response to CO2 Laser treatment in the surgical mode.

A 76-year-old woman presented with facial edema and nodules in the front glabellar region and nasal dorsum that clinically resembled leonine facies. A facial ultrasound showed deposits of permanent facial filler with a "snowstorm" aspect characteristic of silicone oil, and an anatomopathological examination suggested a granulomatous reaction to the exogenous substance. Permanent fillers, such as silicone, behave like foreign bodies and cause a chronic granulomatous reaction. Although dermal fillers have been increasingly used, there is still no consensus on the management of their complications. In the present case, a good response to dapsone was observed.
