Background: At our institution, we noted that children with hematological malignancies and solid tumors often suffered from ingrown toenails (IGTNs) during hospitalization for chemotherapy and stem cell transplantation. However, only few reports have dealt with IGTNs in the above setting.

Procedure: Between August 2007 and July 2017, 180 children who received treatment for hematological malignancies and solid tumors at our institute were enrolled in this study. Read More

Background: Phenol is the gold standard for chemical matricectomy in ingrowing toenail. Recently, trichloroacetic acid (TCA) was used as cauterant. Both agents have high success rates but a postoperative healing time claimed to be faster for TCA rather than phenol. Read More

Retronychia is a recently described cause of ingrowth of the nail plate on the ventral surface of the proximal nail fold. Clinical features are repeated episodes of proximal paronychia, nail plate thickening, and occasionally granulation tissue emergence. The usual treatments for paronychia such as antibiotics and antifungals are ineffective in these cases. Read More

Background: Our routine treatment for ingrown toenail was removal of the surrounding soft tissue and shortening the bone of the distal phalanx. We determined the range and volume of excision based on our experience without an objective standard and routinely performed avulsion of the nail plate.

Objective: To take the nail plate as an objective mark during surgical treatment of ingrown toenail to ensure accurate excision. Read More

The present study evaluated the properties of nails, frequency of ingrown nails in patients with type 2 diabetes mellitus (DM), risk factors for developing ingrown nails, and effect of diabetic polyneuropathy and vasculopathy on the development and outcome of ingrown nails. Our 6-month epidemiologic prospective study included 300 patients with type 2 DM attending a DM outpatient clinic for routine examinations. The general characteristics and foot changes of the study population were investigated. Read More

Eccrine poroma is a rare benign adnexal neoplasm originating from a portion of the intraepidermal eccrine sweat gland duct and the acrosyringium. Typically, the lesions are asymptomatic, slow-growing nodules, which may be found in any sweat gland-bearing area. Multiple red lacunae, glomerular vessels, hairpin vessels, flower- and leaf-like vascular patterns, a polymorphic vascular pattern, globule/lacunae-like structures, a frog egg-like appearance, and comedo-like openings have been defined as characteristic dermoscopic patterns of the disease.

Ingrown toenail, or onychocryptosis, is a common inflammatory disease of the hallux. It results from the alteration of fit of the nail plate in the lateral nail fold. Ingrown toenails are usually seen in adolescents and young adults and can affect daily activities and social life. Read More

Purpose: At our institution, a high proportion of children with onychocryptosis (ingrown toenail) requiring surgical intervention were noted to have a history of hematopoietic stem cell transplantation (HSCT). We analyzed the characteristics of patients who underwent surgical intervention for onychocryptosis and examined our institutional HSCT database to determine if an association exists between onychocryptosis and HSCT.

Materials And Methods: Surgical cases for onychocryptosis performed from 2000 to 2012 were identified. Read More

Retronychia, the posterior embedding of the nail bed into the proximal nail fold, can be a complex clinical dermatologic diagnosis that may mimic other inflammatory ungual diseases or tumors of the nail. It has been related to a history of severe systemic conditions that secondarily affect the nail matrix and is commonly associated with onychomadesis. We present a case of retronychia of the foot with a purely traumatic origin, nonconcomitant with onychomadesis, that was diagnosed by color Doppler ultrasound in a long-time practitioner of martial arts who was otherwise healthy.

Background: Chemical matricectomy is performed mainly by 2 agents, phenol and sodium hydroxide. Chemical matricectomy with phenol has a low recurrence rate and good cosmetic results, but it produces extensive tissue destruction and can result in drainage and a delayed healing time. These adverse effects have brought forward the use of chemical agents such as sodium hydroxide and trichloroacetic acid for matricectomy. Read More

An important component of the Winograd surgical method for an ingrown toenail is total excision of the associated germinal matrix. However, this might not always be accomplished with the procedure. We hypothesized that the surgical results might be improved by adding electrocoagulation of the germinal matrix to the Winograd method. Read More

Paronychia is an inflammation of the tissues alongside the nail. It may be acute or chronic and can be seen in isolation or in association with an ingrowing toenail. Acute paronychial infections develop when a disruption occurs between the seal of the nail fold and the nail plate, providing a portal of entry for invading organisms. Read More

Ingrown nails are defined as inflammation of the lateral nail fold that is caused by penetration by the nail plate and associates with pain and/or infection. The pain associated with ingrown nail hampers walking, raises the risk of falls, and decreases the quality of life.

Onychocryptosis, also known as ingrown toenail, is caused by growth of the lateral edge of the nail into the nail fold. This results in inflammation of the invaded tissue. It is a common problem with ~70% of cases occurring in people between the ages of 12-30 years and causes significant discomfort, pain, and restriction in activity [1]. Read More

Ingrown nail surgery is the one of the most common surgeries in outpatient clinics that are generally perfomed in response to patient complaints. Still, making simple observations, taking patient histories and conducting further tests are often neglected by outpatient clinics. Consequently, it is important to be aware if ingrown nail is associated with any underlying diseases that can lead to major complications. Read More

Background: Many risk factors have been identified to be associated with ingrown toenail. Internal pressure by the distal phalanx of the hallux and the second toe and external compression from the shoes has been proposed as a reason for the pathology. The main objective of the study was to analyze the existence of a correlation between the presence of pathological hallux interphalangeal angle (HIA) and risk of ingrown hallux nail. Read More

Retronychia represents proximal ingrowth of the nail that occurs when the nail embeds backwards into the proximal nail fold. It is suspected when there is a persistent paronychia, particularly in the setting of trauma. Important clinical criteria for diagnosis are inflammation of the proximal nail fold, granulation tissue emerging from under the nail fold, thickening of the proximal portion of the nail plate and interruption of nail growth.
