Contact dermatitis due to orchids (Cymbidium and Oncidium).
A 64-year-old male who cultivated orchids as a hobby, had noticed itchy erythematous lesions on both hands since 6 months earlier. His eruptions had gradually worsened and scales and fissures had appeared. Although he was treated with topical corticosteroids by a doctor, his erythema showed no improvement. Patch tests with the orchids he cultivated, fertilizers, antiseptics and insecticides showed positive reactions to the stems of Cymbidium and Oncidium orchids. A diagnosis of contact dermatitis attributable to the cultivated orchids was made.
