Tulipalin A causes allergic contact dermatitis in floral workers handling Alstroemeria. Misdiagnosis is common, but patch testing with tulip bulb components can confirm this phytotoxicity.

Area of Science:

  • Dermatology
  • Allergology
  • Toxicology

Background:

  • Tulipalin A, a glycoside from tulip bulbs, causes allergic contact dermatitis (phytotoxicity) in floral workers exposed to Alstroemeria.
  • This condition presents as fissured acropulpitis, hyperpigmentation, onychorrhexis, and paronychia, particularly on the volar surfaces of sensitized individuals.

Observation:

  • Dermatitis and paronychia are common, leading to potential diagnostic errors.
  • A case of Tulipalin A phytotoxicity was initially misdiagnosed as tinea manuum in a patient with occupational exposure.

Findings:

  • Accurate diagnosis requires a detailed patient history and confirmatory patch testing.
  • Patch testing involves using a bulb sliver and tuliposide A exposure.

Implications:
