RESUMEN
"Green nails" or chloronychia results from an infection mostly caused by Pseudomonas sp. but also from other bacterial or fungal contamination. Its presents as a typical triad: green discoloration of the nail plate with proximal chronic paronychia and disto-lateral onycholysis. In a moist environment, Pseudomonas colonizes onycholysis of any origin (traumatic, inflammatory or tumoral). Nail color varies from pale green to dark green, almost black. Treatment consists in cutting of the detached nail plate, brushing the nail bed with a 2% sodium hypochlorite solution twice daily accompanied by moisture eviction by wearing latex gloves over cotton ones for all daily household tasks.

HAND INFECTIONS. Hand and finger infections are very common. They result from the inoculation of a germ through the skin barrier. They can range from simple paronychia to extremely serious necrotizing fasciitis. Certain infections, such as those resulting from bites, have their own specific characteristics, which will determine how they are managed. While management can be medical in the early stages, it is important not to ignore the need for surgical treatment, otherwise serious complications may arise, leading to functional and aesthetic sequelae. Delays in treatment cannot be made up. Any infectious lesion can be potentially serious and must be treated in an appropriate department if there is the slightest doubt.
INFECTIONS DE LA MAIN. Les infections de la main et des doigts sont très fréquentes. Elles résultent de l'inoculation d'un germe à travers la barrière cutanée. Elles vont du simple panaris à la gravissime fasciite nécrosante. Certaines infections, comme celles faisant suite aux morsures, ont des caractéristiques propres dont dépend la prise en charge. Si elle peut être médicale au stade initial, il est important de ne pas méconnaître le moment du traitement chirurgical sous peine de voir survenir des complications graves responsables de séquelles fonctionnelles et esthétiques. Le retard à la prise en charge ne peut être rattrapé. Toute lésion infectieuse peut être potentiellement grave et, au moindre doute, doit être prise en charge dans un service adapté.

Familiarity with common nail disorders enables the clinician to diagnose and treat nail disorders and to recognize red-flag conditions. Knowledge of the anatomy of the nail unit is essential to understand the origin of nail disorders. This article focuses on neoplasms, abnormalities of nail color and shape, infections, and inflammatory conditions of the nail unit. There are various neoplasms of and around the nail unit, like squamous cell carcinoma (in situ), melanoma, and benign neoplasms such as mucous cyst, subungual exostosis, glomus tumor, onychopapilloma and fibro(kerato)ma. The most common deviating colors of the nail are red, white and brown-black. Abnormalities of nail color and shape may indicate an underlying systemic disease. Infections of the nail unit include onychomycosis, acute paronychia, pseudomonas nail infection and verruca vulgaris. The inflammatory conditions we discuss in this article are chronic paronychia, psoriasis, alopecia areata and lichen planus.

Paronychia is a common inflammatory condition of the nail fold that is often associated with infection. Causes can be fungal, viral, or most commonly, bacterial. Neonatal paronychia is a rare presentation with only one previously reported case in the literature of a patient younger than 1 month of age. This is a case of an 8-day-old neonate with acute bacterial paronychia caused by clindamycin-resistant Staphylococcus aureus.

Apert syndrome is a complex congenital syndrome that includes bicoronal craniosynostosis, craniofacial dysmorphologies, cleft palate, hearing loss, spina bifida occulta, cardiac anomalies, and affects the upper and lower extremities-producing complex syndactyly in these patients. Management of the hands yields several challenges and mandates close follow-up to balance repair of complex polysyndactyly with other pressing interventions, such as posterior cranial vault distraction and surgical management of the airway. Our goals of therapy for the hands are to preserve 10 digits, provide sufficient soft tissue coverage, optimize hand function, and minimize the number of surgical interventions. Ideally, surgical management of the hand differences occurs between the ages of 9 months and 2 years, to optimize neurocognitive development. In complex syndactyly observed in patients with Apert syndrome, there are broad, conjoined nail plates that overlie the fused digits, and paronychia occurs frequently. Suppurative infections can delay definitive surgical intervention for the patient's complex syndactyly, and resolution of paronychia is critical. This study aims to propose an effective and safe technique to manage paronychia when it occurs in patients with Apert complex syndactyly and to mitigate the length of delay to definitive polysyndactyly reconstruction. In the context of these patients' need for multiple surgical interventions within the first few years of life, this strategy for preventing or mitigating paronychia can play an important role in streamlining their complex surgical management while avoiding multiple cancellations.

BACKGROUND: The onychodystrophies associated with Sézary syndrome (SzS) have rarely been described in the literature. We performed a retrospective analysis of SzS patients at a single institution and compared our data with previous publications. OBJECTIVES: The objectives of this study were to identify and describe the most frequent nail alterations in patients with SzS. METHODS: A retrospective analysis was performed with some prospective observations at the University of Pittsburgh from 1989 to 2017. RESULTS: We identified 54 patients with SzS out of 535 patients with cutaneous T-cell lymphoma. Nineteen patients with SzS had photos of their nail. All those patients exhibited some type of onychodystrophy. The most common types were paronychia (63.2%; 12/19), leukonychia (42.1%; 8/19), onycholysis (42.1%; 8/19), trachyonychia (31.6%; 6/19), and subungual hyperkeratosis (26.3; 5/19). Cluster analysis of our data in comparison with published data on the psoriatic nails indicated that while leukonychia, onycholysis, subungual hyperkeratosis, and nail discoloration were frequently observed in psoriasis, onychauxis, anonychia, distal notching, and onychoschizia occurred more commonly in patients with SzS. CONCLUSIONS: The most common nail manifestations in SzS patients included paronychia, leukonychia, and onycholysis. The nail manifestations in SzS patients appeared to be heterogeneous, while onychauxis, anonychia, distal notching, and onychoschizia seem to be specific to SzS in comparison with psoriasis.

Abstract: Retronychia is a recently described disorder caused by ingrowth of the proximal nail plate into the proximal nail fold. It is suspected when there is persistent paronychia, particularly in the setting of trauma. This disease is probably underdiagnosed due to limited knowledge among dermatologists and the presence of incomplete clinical forms. Nail plate avulsion is the diagnostic and curative procedure of choice, despite reports of relapse.

Retronychia is a clinical condition resulting from embedding of the nail plate into the proximal nail fold. We report two adolescent girls, 14 and 16 years of age, with a history of chronic proximal paronychia of the great toe, one of them developing osteomyelitis. After failure of treatment with several systemic antibiotics, nail avulsion was performed, leading us to the diagnosis of retronychia and with rapid and complete resolution of symptoms in both cases. Delay in diagnosis of retronychia can lead to local complications and prolonged discomfort.

Congenital malalignment of the great toenails (CMGT) has been well documented. In the present case, it was complicated by acute paronychia. It is important for physicians to recognize and treat CMGT to prevent sequelae such as onychocryptosis, onychogryphosis, and recurrent paronychia.
