AB  - Importance: Although Pyemotes species have been known to cause dermatitis, recent
      reports are rare. During the past 30 years, only 3 outbreaks of dermatitis caused
      by Pyemotes ventricosus have been reported. Objective: To analyze the causative
      agent of skin changes in employees of a company that produced herbal medicines.
      Design, Setting, and Participants: This case series includes 18 patients (8 men, 
      10 women; mean age, 44 years) who contracted unusual dermatitis after an
      occupational exposure in July and August of 2012 while working for a company that
      produced herbal medicines. The patients were examined at the Lower Silesia
      Regional Centre of Occupational Medicine in Wroclaw, Poland. Exposures: Workers
      weighed and packed 1 part of the Helichrysum arenarium herb. Main Outcomes and
      Measures: We hypothesized the causative agent to be P ventricosus. An examination
      of the herbal specimens for ectoparasites confirmed the diagnosis. Results:
      Initially 16 employees developed pruritic skin changes. Skin lesions with
      pruritic vesicles on an erythematous base with surrounding swelling and edema
      were observed. Several employees also developed a flulike illness. After 44 days,
      2 new employees presented with the same skin changes. The analysis of working
      conditions showed that the same part of the H arenarium herb was weighed and
      packed at that time. Conclusions and Relevance: We found that changing the time
      when the herbs were weighed and abandoning gas fumigation containing methyl
      bromide resulted in the recurrence of an almost forgotten disease.
