Nail unit surgery requires that the surgical field be free of bleeding to allow good visibility of the structures and lesions involved.There are several types of tourniquets aimed at meeting this requirement, each with its advantages and disadvantages.We present a new and simple buckle tourniquet that is adjustable, safe, and cost-effective.

Introduction: Transverse over curvature is a commoninaes the tic and pain ful deformity of the nail plate. There are several conservative and surgical techniques for trea ting this condition. We describe a simple and cost effective techni que using auto logous dermal grafts.

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: Workshops are offered during Dermatological Meetings in order to teach surgical procedures, both live and in detail. Nevertheless, access to post-operative developments, as well as to the results obtained, are restricted to the physicians from the medical services responsible for organizing these events. Objective: To assess, and make known, the progress and results of previously operated cases. Methods: Eight patients with different pre-operative diagnoses were operated on the nail surgery workshop that occurred during the Brazilian dermatological meeting RADESP 2011, with a nine-month follow up. The results were evaluated using photographs, taken every three months, by the surgeons responsible for the surgeries. Results: Of the eight operated cases, two were considered as yielding satisfactory results (one with mild dystrophy of the nail plate and the other with time considered insufficient for better assessment), and five were deemed as cured. One case did not return for the follow-up visits. Conclusion: Following up and presenting the post-operative development of these patients as well as publishing the responsible surgeons' evaluations, complements the knowledge acquired by the workshops' attendees, and that of other participants at the meetings.

Transverse hypercurvature is a deformity of the nail plate, unaesthetic and painful, causing discomfort to the patient. Treatment can be conservative or surgical. Related to the conservative treatments, placing the flexible plastic blade on the nail plate using cyanoacrylate glue, promotes rapid improvement of pain and its widening from three to six months. The use of cyanoacrylate accelerator facilitates the procedure, making it faster.

Viral warts are one of the most prevalent dermatoses. The clinical picture varies from a single lesion with spontaneous cure to multiple recalcitrant lesions. Bleomycin sulfate is a cytotoxic action drug approved for the chemotherapeutic treatment of some malignancies. There are a number of studies that have been carried out during the last 45 years demonstrating its usefulness in dermatology, especially in intralesional therapy for viral warts, meaning it is an excellent option for lesions in difficult-to-handle topographies and for cases that do not respond to other approaches.

The “harpoon nail” is a variant of the ingrown toenail. In this condition, the nail spicule pierces the distally growing periungual tissue and may emerge through the hyponychium. Its diagnosis can be confirmed by high-frequency ultrasound, facilitating the therapeutic programming.

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.
