Introduction: Chronic paronychia is an inflammatory disease of the proximal nail fold that usually lasts for more than six weeks. Surgical of removal the proximal nail fold is recommended in cases that are resistant to clinical treatment. Objective: To analyze the long-term response to the surgical treatment of chronic paronychia. Methods: Prospective cohort study of 62 patients who had undergone surgical treatment to correct chronic paronychia from November 2004 to April 2008. The patients were asked to return for reassessment and clinical observation of the presence or absence of signs of chronic paronychia and were classified into two groups: cured and uncured. Results: Of the 62 patients, 12 attended the clinical reassessment, for a total of 31 procedures for analysis. The average length of patient follow-up was 5 years and 2 months. The results were maintained in 27 (87%) of the procedures performed. Conclusions: Surgical removal of the proximal nail fold is a good option for the treatment of chronic paronychia due to its simplicity, effectiveness, and long-lasting results.

Onychomatricoma is a benign neoplasia that occurs pecifically in the nail apparatus. It was described in 1992, and is the only tumor in which the change of the nail plate is actively caused by the lesion. It lies in the nail matrix,and has fingerlike projections that are embedded in the nail plate, resulting in thickening, longitudinal grooves, yellow discoloration and splinter hemorrhages. Although described as a rare tumor, it is believed to be underdiagnosed. The present study is aimed at reviewing onychomatricoma’s clinical features as well as the complementary examinations that are used to recognize and diagnose this tumor.

Introduction: The reconstruction of surgical defects resulting from the excision of tumors in the nose is a challenge for dermatologic surgeons due to its rigid structure and low mobility. The Mohs Micrographic Surgery technique allows the preservation of healthy tissue and leads to a smaller surgical wound. Objective: To demonstrate techniques for surgical correction of defects after removal of tumors of the nose through Mohs Micrographic Surgery, according to the anatomical location of the tumor. Methods: Descriptive study of patients operated on using Mohs Micrographic Surgery during the period 1996-2010. Patient images taken pre-, intra-, and post-operatively were analyzed with the aim of classifying the defect's anatomic location and the type of surgical reconstruction adopted. Results: 170 patients (totaling 203 lesions) were included in the study. The most common locations for tumors were (in descending order): nasal ala, dorsum, tip, and lateral wall. The advancement flap was the most common reconstruction type for lesions located in the lateral wall and in the nasal ala. Grafts were most often used in lesions located in the tip of the nose. Grafts and advancement flaps were more frequently used in the dorsum of the nose. Conclusions: The parameters that provide guidance on choosing the best reconstruction method must take into consideration the size and location of the surgical defect.

Rosacea can develop into phyma, which is characterized by hypertrophy of sebaceous glands and proliferation of connective tissue and blood vessels. Regarded as a serious complication, phymas are more common in men, being more frequent in the nose — when it is called rhinophyma. Rosacea and rhinophyma can cause functional and aesthetic impairment, leading to a worsening in the patients' quality of life. Pharmacological and physical therapies are performed in initial stages, however phymatous variants of the condition respond poorly to the first. The authors of the present article report a case of surgical correction of a giant rhinophyma using the shaving and electrocoagulation techniques, with excellent aesthetic and functional outcomes.

Basal cell carcinoma over the tattoo region has been poorly reported in the literature, with a total of 13 cases. All cases describe the clinical aspect of the lesion and its pathogenesis but do not characterize the dermoscopy. We report two cases of basal cell carcinoma on tattoos with clinical and dermoscopy features, treated with Mohs micrographic surgery. It was challenging to establish the tumor’s clinical and dermoscopic margins due to the tattoo’s exogenous pigment.
