Phytophotodermatitis from citrus juice can cause long, hyperpigmented lesions mimicking jellyfish stings. Diagnosis relies on the absence of pain and jellyfish venom antibodies.

Area of Science:

  • Dermatology
  • Toxicology

Background:

  • Phytophotodermatitis is a skin reaction caused by contact with plants and subsequent exposure to light.
  • Citrus fruits are known photosensitizing agents, but severe presentations are uncommon.

Observation:

  • Two cases presented with extensive, long, hyperpigmented macular lesions.
  • The lesions resembled those typically seen after jellyfish envenomation.

Findings:

  • The phytophotodermatitis lesions were characterized by a lack of local pain and signs of envenomation.
  • Serological tests for jellyfish venom antibodies were negative in both patients.

Implications:

  • This highlights the importance of considering phytophotodermatitis in the differential diagnosis of lesions mimicking marine envenomation.
