“…These may be in the form of tight‐fitting footwear, shoes with high heels, and activities such as running, hiking, mountaineering, dancing, and gym. Other factors include causes of interruption of nail matrix growth, such as ischemia, distal edema, thrombophlebitis, etc 3,4 . Podiatric predisposing factors like Egyptian foot type and great toenail congenital malalignment may also play a role.…”

Retronychia describes the proximal ingrowing of the nail plate. In the early stage, topical steroids are the gold standard therapy, while in the late stage surgical treatment is mandatory. We identified an intermediate severity stage of retronychia, where the topical treatment alone is ineffective and surgery is avoidable. Intralesional steroids turn the best treatment in these patients. A pilot study consisting of a 3-month treatment period and 9-month follow-up time was designed to evaluate the treatment outcome to intralesional steroid injections in patients affected by the intermediate-stage of toenail retronychia. The complete recovery of retronychia-associated nail abnormalities was observed in 27/28 recruited patients at the end of the treatment phase. Paronychia, nail plate discoloration, proximal nail fold (PNF) elevation, and discharge were reduced (P < .01) after one steroid administration, while nail regrowth became significant after two sessions. No significant difference in terms of clinical outcome was found, while pain VAS score and intra-operative pain evaluated with Wong-Baker faces scale were higher in the female group (P < .01). Limitation Lack of control group of patients. Despite its temporary effect, the intralesional triamcinolone injection is an effective, cheap, and safe treatment especially for the intermediate stage of retronychia.

“…In literature, two stages of retronychia are described 4 : “ Early‐stage ” characterized by arrested nail growth, yellowish discoloration, and mild exudate from the proximal nail fold. “ Late‐stage ” with the overmentioned symptoms along with severe paronychia and elevation of the PNF. …”

“…Retronychia refers to the proximal nail plate ingrowth into the proximal nail fold [4]. Approximately 140 cases of retronychia have been reported in the literature until now [5-7], whereas recently a large series of 56 cases was published [6]. The diagnosis of retronychia is clinical and must be suspected in cases of persistent paronychia, particularly in the setting of trauma.…”

“…Chronic proximal paronychia, onycholysis, emerging of granulation tissue from under the nail fold, xanthonychia, and thickening of the proximal portion of the nail plate include the clinical diagnostic criteria for retronychia [7]. The differential diagnoses of retronychia include subungual benign and malignant tumors, cysts, and diseases that can present as chronic paronychia (e.g., fungal and bacterial infections) [7]. Total avulsion of the nail not only constitutes the treatment of choice for retronychia but also confirms the diagnosis and allows rapid pain relief.…”

is a disorder caused by ingrowth of the proximal nail plate into the proximal nail fold and is suspected in cases of unresolved chronic proximal paronychia. • Superficial acral fibromyxoma is a rare benign tumor of soft tissues commonly located in the subungual or periungual area. Novel Insights • Total avulsion of the nail constitutes the treatment of choice for retronychia and can reveal the existence of a subungual superficial acral fibromyxoma as a cause of this condition.

Painful nails: A practical approach to the diagnosis and management of painful nail conditions

Because several nail disorders share similar clinical features, their diagnosis and management can be challenging to clinicians. The physical examination may disclose localized abnormalities or point to an underlying systemic disease, requiring additional workup. Furthermore, cosmetic distress and nail-related symptoms (e.g., tingling, stinging, numbness, and pain) are common factors that influence the patient's search for medical assistance. Nail pain (i.e., onychalgia) can accompany both localized and systemic pathology. Onychalgia can be acute or chronic according to the time of evolution; patients may describe it as intermittent or constant, and as a throbbing, burning, sharp, or shooting sensation denoting the nature of the pain. It may be exacerbated by colder temperatures, touch, and increased activity (e.g., manipulating objects, walking). We present four main groups of conditions that might cause nail pain: nail tumors, nail deformities, inflammatory or infectious diseases, and external or traumatic agents. Our article includes an overview of the clinical features, as well as diagnosis and management pearls for each entity. Physicians (dermatologists and nondermatologists) should be aware that abnormalities of the ungual and subungual space are not exclusive of dermatological disorders but may also be present in noncutaneous contexts.
