“…The ectopic nail can present as a small outgrowth of normal nail or a complete double nail malformation. 7 Nail orientation has been described as occurring vertically, horizontally, or circumferentially around the digit. 2,8 There may occasionally be deformity of the underlying bone in congenital cases, which can result in bony hypoplasia and thinning of the phalanx.…”

Background Onychoheterotopia, or ectopic nail, is a rare nail condition in which nail growth occurs in areas other than the distal phalanges. The majority of cases in the literature are noted to be congenital; however, acquired cases have less commonly been described following either acute or chronic trauma. Methods We present a case of acquired onychoheterotopia in a child, with a corresponding literature review of acquired pediatric onychoheterotopia cases for comparison. Results There were a total of 10 cases of acquired onychoheterotopia in pediatric patients in the literature. Including our patient, 81.8% (9/11) developed an ectopic nail on the fingers. Crush injury preceded the ectopic nails in 45.5 % (5/11) of cases. Infection occurred in 27.3% (3/11). Conclusions Although the incidence and prevalence of acquired onychoheterotopia are unknown, it seems to be an uncommon phenomenon. From our case and others from the literature, there may be associations with crush injury specifically. Further research will be needed to fully elucidate the pathophysiology and risk factors for ectopic nail growth.

“…In all case reports, patients who underwent excision were symptom-free and recurrence-free at the time of follow-up. 3 – 5 , 7 Although risk factors for and prevention of PTEN formation have not been specifically studied, it seems logical that a thorough examination of the wound at the time of injury and recognition of a germinal matrix injury, followed by thorough irrigation and anatomical repair, may reduce its incidence, as the majority of cases in the literature arise after unrecognized (and therefore unrepaired) germinal matrix injury.…”

Summary: Post-traumatic ectopic nail is an uncommon entity that is occasionally observed after trauma to the fingertip and nail, resulting in aesthetic and functional morbidity. We report a case of post-traumatic ectopic nail in a 3-year-old girl following trauma to her index finger and subsequent surgical intervention to remove an inclusion cyst. The unusual clinical sequence is presented to highlight the etiology and treatment of this rare lesion.

“…It was first reported by Ohya in 1931 2. It is a rare entity and can be either congenital or acquired (post-traumatic), with the latter being rarer, with only a few cases reported so far 3…”

“…These traumatic influences lead to fragmentation and embedding of the germinal matrix, or heterotopic inoculation of the nail bed cells, that is, oncocytes 1. Histopathological features include mature nail unit with keratotic squamous epithelium, including a corneous nail plate and nail matrix, confirming the diagnosis 3. Ectopic nail often manifests as a complete double fingernail deformity or a partial extension of an aberrant nail.…”
