Lymphomatoid contact dermatitis to an exotic wood: a very harmful toilet seat.
We report the case of a 58-year-old man who experienced a 2-year history of arciform rash of the buttocks associated with an intense pruritus. The lesion worsened despite several multipotent topical steroid courses. Punch biopsy with immunohistochemistry of the lesion was suggestive of lymphomatoid contact dermatitis, and extensive screening for cutaneous T-cell lymphoma (CTCL) remained totally negative. Lymphomatoid contact dermatitis is an inflammatory disease that can clinically simulate malignant lymphoma. Although the course of the disease is considered to be benign, it should be regarded with attention as it has been hypothesized that the condition could be a precursor of CTCL.
