A patient developed subungual squamous cell carcinoma in multiple digits, linked to occupational exposure to stagnant wastewater and human papillomavirus (HPV) infection. This case highlights a potential occupational risk for HPV-associated skin cancers.

Area of Science:

  • Oncology
  • Dermatology
  • Virology

Background:

  • Subungual squamous cell carcinoma (SCC) is a rare malignancy affecting the nail unit.
  • Occupational exposures are increasingly recognized as potential risk factors for various cancers.
  • Human papillomavirus (HPV) is a known oncogenic virus implicated in several epithelial cancers.

Observation:

  • A patient with a 22-year career in wastewater management presented with subungual SCC in multiple digits.
  • The patient reported daily hand contact with stagnant wastewater.
  • Immunohistochemical analysis revealed positive staining for HPV within the tumor tissue.

Findings:

  • The presence of HPV in subungual SCC suggests a potential etiological role for the virus in this specific presentation.

Related Experiment Videos

  • The patient's occupation involving prolonged contact with wastewater represents a unique exposure scenario.
  • Multifocal occurrence of the cancer points towards a systemic or widespread localized risk factor.

    • Implications:

    • This case underscores the importance of considering occupational exposures in the etiology of rare skin cancers.
    • Further research is warranted to investigate the link between wastewater exposure, HPV infection, and the development of subungual SCC.
    • Preventive measures and awareness among workers in similar occupations may be necessary to mitigate cancer risk.
