Introduction: Chronic paronychia is an inflammatory disorder of the proximal nail fold (PNF) lasting more than six weeks that accounts for 18% of nail dystrophies. Clinically, it is characterized by inflammation of the PNF, absence of the cuticle, and dystrophy of the nail plate. Clinical treatment is usually unsatisfactory. Surgical treatment consists on the removal of the PNF, which can be done using the oblique or perpendicular incision techniques.
Objective: The objective of the present study was to compare the efficacy of oblique and perpendicular surgical techniques in the treatment of chronic paronychia.
Methods: Sixty-two patients with chronic paronychia, in one or more fingers (with a total of 138 surgeries), were randomly divided into two groups, according to the surgical technique used (perpendicular or oblique incision). Postoperative evaluation was done after six months using a three-point scale: absence of improvement, improved, cured.
Results: One hundred and thirty-four cases (97.1%) were considered cured, and 4 (2.9%), two in each group, were considered as having improved.

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.

Keloids were first described several centuries ago, however their handling and treatment are still often inadequate. A number of treatments are available, such as intralesional corticotherapy and compressive therapy. The case of a 24-year-old female patient with a 5 year history of keloids in the ear lobules, with recurrence after treatment, is reported. She experienced a full regression of the lesions (for 2 years) after surgical reduction followed by intralesional bleomycin injections. Bleomycin is emerging as a therapeutic option with few side effects and lasting results for keloids that are unresponsive to conventional treatments.

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.

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.

A 77-year-old patient presents a case of primary cutaneous ductal eccrine carcinoma in the parietal region of the scalp. The biopsy showed a carcinoma with a ductal and infiltrative pattern, suggestive of metastatic neoplasia. An invasive carcinoma with eccrine tubular pattern was identified. The mastologist and oncologist did not detect primary lesions in other organs. Based on clinical and immunohistochemical analyses, the diagnosis was primary cutaneous eccrine carcinoma. Mohs micrographic surgery was performed with three phases to get a free margin. The tumor presented deep infiltration of the subcutaneous tissue and galea aponeurotica.
