Mycosis Fungoides Presenting as Pigmented Purpuric Dermatitis
Mycosis fungoides, a cutaneous T-cell lymphoma, typically presents as indolent, progressive, and persistent erythematous patches or plaques with mild scaling and over time can evolve into tumor stage with tumor nodules. Other presentations include eczematous, psoriasiform, poikilodermatous, and hypopigmented patches. We report Mycosis fungoides in a 14-year-old boy presenting as pigmented purpuric dermatitis and review the relevant literature. This is a rare presentation of a condition that is uncommon in the pediatric population. In our patient, histologic features were typical of Mycosis fungoides presenting as pigmented purpuric dermatitis. The clinical features, pathology, molecular biology, and the relationship between these two entities are discussed.
