Mycosis fungoides involving the oral mucosa in a child.

Involvement of the oral mucosa in cutaneous T-cell lymphoma is uncommon and is usually associated with a poor prognosis (the majority of patients dying from the disease within 3 years of the diagnosis of oral involvement). We report the first case of intraoral mycosis fungoides occurring in a child. In addition, our patient has had intraoral disease for 3 years and is currently systemically well with no evidence of cutaneous or systemic disease progression.
