Contact dermatitis methyl methacrylate

Humans have developed strong skin reactions when rechallenged with the liquid. Allergic contact dermatitis has been reported in workers handling methacrylate sealants, including methyl methacrylate. In another report, five subjects were shown by bronchial provocation tests to have occupational asthma due to methyl methacrylate or cyanoacrylates. ... 

Hearing aids are designed to fit snugly in the ear and infrequently are associated with such an intense dermatitis as to require discontinuance (Lear et al. 1998). Clinicians tend to diagnose this as seborrheic dermatitis, which it strongly resembles, or to contact sensitization to methyl methacrylate, neither of which are acceptable explanations.

The causes of allergic contact dermatitis (31 cases) were rubber chemicals (6 cases), nickel (5 cases), phenol formaldehyde resin (3 cases), epoxy resin (3 cases), formaldehyde (2 cases), medications (2 cases), and chromium, dibutylhiourea (Kanerva et al. 1998), 4,4 -diphenylmethane diisocyanate (MDI), glutaralde-hyde, hydroxyl ammonium chloride (Estlander et al. i997 )> methacrylates, 2V-methyl-N-nitroso-p-toluene-sulfonamide (Estlander et al. 1996a) and potassium persulfate (1 case each), and unspecified agents (2 cases). 

Methyl methacrylate is one of the most common methacrylates. This acrylic monomer, the essential component of the fluid mixed to the powder, may cause allergic contact dermatitis mainly in dental technicians and dentists. Cases were also reported in those using sculptured nails and in ceramics workers.
