AI Article Synopsis

  • Intraocular iris rhabdomyosarcoma is extremely rare, typically reported as a primary tumor, and this case highlights its occurrence as a metastasis from a foot tumor.
  • An 18-year-old female had a rhabdomyosarcoma in her foot that spread to her iris, prompting referral for treatment after a partial remission and signs of relapse during chemotherapy.
  • Despite treatment with radiotherapy, the patient unfortunately passed away two months later, demonstrating the aggressive nature of this metastasis and the rarity of secondary iris involvement.

Article Abstract

Background: Intraocular iris rhabdomyosarcoma is extremely rare, and in the 3 cases reported to date occurred as the primary site of tumour growth. We report a case of rhabdomyosarcoma of the foot metastasizing to the iris.

Case Presentation: An 18-year-old white female was referred to the London Ocular Oncology Service for management of a metastatic rhabdomyosarcomatous deposit in the iris, a metastasis from alveolar rhabdomyosarcoma of the foot. She was diagnosed nearly 2 years earlier with the primary sarcoma with extensive systemic spread and treated by resection of the foot lesion and chemotherapy, and achieved a partial remission. The left iris deposit was noted while she was receiving systemic chemotherapy, heralding a relapse. However, anterior uveitis and raised intraocular pressure developed and she was referred to our service for further management. A left iris secondary rhabdomyosarcoma deposit was noticed and in addition a lacrimal gland mass, as indicated by ultrasound B scan of the eye and orbit. The patient was treated with external beam radiotherapy to the globe and orbit, but died 2 months after treatment completion.

Conclusion: Rhabdomyosarcoma of the iris is very rare and was previously documented only as a primary malignancy in this location. We report that secondary spread to the iris can also occur, in this case as the first sign of widely disseminated systemic relapse.

Article Synopsis
  • Hand, foot, and mouth disease (HFMD) caused by enterovirus A71 (EV-A71) currently has no specific treatments, but Pien Tze Huang (PZH) shows promise in inhibiting the virus's replication.
  • Research indicates that PZH significantly reduces viral protein expression and viral loads in cells and protects mice from EV-A71 infection, outpacing the effects of the common antiviral drug Ribavirin.
  • A study of the underlying mechanisms suggests PZH may work by suppressing certain cellular pathways (PI3K/AKT/mTOR and NF-κB), indicating its potential as a therapeutic option for managing EV-A71 infections.

Involvement of cell surface glycosaminoglycans in chebulagic acid's and punicalagin's antiviral activities against Coxsackievirus A16 infection.

Background: Coxsackievirus A16 (CVA16) is responsible for several recent outbreaks of Hand, Foot, and Mouth Disease in the Asia-Pacific region, and there are currently no vaccines or specific treatments available. We have previously identified two tannins, chebulagic acid (CHLA) and punicalagin (PUG), as efficient entry inhibitors against multiple viruses known to engage cell surface glycosaminoglycans (GAGs). Interestingly, these two phytochemicals could also block enterovirus infection by directly inactivating CVA16 virions, which were recently reported to utilize GAGs to mediate its entry.

EV-A71 is a common viral pathogen that causes hand, foot and mouth disease. It is a single-stranded RNA virus that has a low fidelity RNA polymerase and, as a result, spontaneous mutations frequently occur in the EV-A71 genome. The mutations within the genome give rise to quasispecies within the viral population that could be further defined by haplotypes.

Electronic address:

The mechanisms underlying tissue-specific replication of enteroviruses are currently unclear. Although enterovirus A71 (EV-A71) and coxsackievirus A16 (CV-A16) are both common pathogens that cause hand-foot-mouth disease, they display quite different neurotropic properties. Herein, we characterized the role of the internal ribosome entry site (IRES) in determining neurovirulence using an oral inoculation model of EV-A71.
