AI Article Synopsis
- Onychoheterotopia is a rare condition where nails grow in unusual areas, often noted as congenital, but some cases can be acquired after trauma.
- A case study of a child with acquired onychoheterotopia was presented, along with a review of other pediatric cases for comparison.
- Among the reviewed literature, a significant number of cases were linked to crush injuries and infections, suggesting specific risk factors, though overall data on this condition remains limited and requires more research.
Article Abstract
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.

Alteration in the ubiquitin-proteasome system results in human disorders with neurological and/or autoinflammatory presentation. Haploinsufficiency of PSMD12, which encodes a subunit of the core component of the proteasome, causes Stankiewicz-Isidor syndrome (STISS), characterized by intellectual disability, autism spectrum disorder, craniofacial dysmorphisms, with or without other congenital anomalies, and autoinflammation. We described six patients (four adults) from two unrelated families carrying a known p.

Introduction And Importance: Post-traumatic ectopic nail (PTEN) refers to the abnormal growth of a new nail in a site other than the usual one, typically occurs after a trauma to the nail matrix. The exact pathogenesis is still unknown. This rare condition often affects the dorsal aspect of the phalanx.

Background: Inflammatory arthritis encompasses a group of immune-mediated diseases characterized by chronic joint inflammation. Despite having pathogenic mechanisms in common, the prognosis of rheumatoid arthritis (RA), psoriatic arthritis (PsA), and undifferentiated arthritis (UA) could be different regarding progression to chronic, to erosive, or to self-limited disease. Our aim was to evaluate the potential association of synovial tissue (ST) inflammatory cell infiltrate, the presence of ectopic lymphoid neogenesis (LN +) structures, and poor prognosis factors (PPF) in patients with RA, PsA, and UA.

Article Synopsis
- WDR35 variants are linked to Cranioectodermal dysplasia (CED), a rare genetic disorder characterized by facial and skeletal abnormalities, growth issues, and other systemic complications.
- A case report highlights the first Chinese patient with CED caused by WDR35 variants, presenting atypical symptoms such as ectopic testis alongside common CED traits.
- This case enhances the understanding of the relationship between specific genetic variations (genotype) and observable traits (phenotype) in CED, offering valuable insights for genetic counseling.
