Introduction: Pincer nails are characterized by an over-curvature of the nail in the transverse axis, causing the pinching of the nail bed at its distal portion. It most commonly affects the toes, occurring rarely in the fingers. Objective: To demonstrate the Fanti's technique for the treatment of pincer nails. Methods: Eleven patients from the Hair and Nails Ambulatory, bearing pincer nails, underwent surgery for the correction of the condition with the Fanti's technique. Results: All patients had complete clinical improvement during the 14-month follow-up period. Conclusions: The present study demonstrates the Fanti's surgical technique for the correction of pincer nails, where anatomical and functional improvement of the operated nails could be observed.

Introduction: Tuberous sclerosis is a dominant autosomal genodermatosis, classically characterized by facial angiofibromas, fibrotic plaques, periungual fibromas, leaf-shaped hypochromic maculae and fibrous frontal plaques.
Case report: A patient bore this disease, with Koenen tumors in all nail beds of hands and feet, which were resistant to the conventional treatment — simple excision and electrosurgery. Amputation of the nail beds was performed followed by reconstruction with full thickness skin grafts.
Conclusion: The amputation of the nail apparatus and reconstruction with full thickness skin grafts in aggressive, recurrent or high morbidity cases can be an effective therapeutic option.
