  • Objective:

    We present the case of a 59-year-old Chinese patient with an unusual presentation of mucosal plasmacytosis involving the oropharynx, related to the use of toothpaste.

    Method:

    Case presentation and review of English medical literature involving mucosal plasmacytosis.

    Results:

    Mucosal plasmacytosis is an uncommon disease process and has been associated with hypersensitivity reactions. Most cases involve the gingival mucosa, although there have been reports of cases involving other oral mucosal sites and the upper aerodigestive tract. Our case provides an example of oropharyngeal plasmacytosis related to toothpaste. A resolution of signs and symptoms followed withdrawal of the suspected allergens.

    Conclusion:

    Mucosal plasmacytosis is a benign inflammatory process that may appear to be more sinister on clinical examination. Skin patch testing is a useful adjunct in confirming the diagnosis.
