Part of the Clinical Cases in Dermatology book series (CLIDADE)


Mycosis fungoides (MF) is an uncommon disease in children, but also in this age it must be considering a possible differential diagnosis in order to avoid a late diagnosis. We report the case of a 10-year-old boy with a classic MF, presenting with a single xerotic, mildly pruritic patch of the hip. Common features of classic MF are usually patches, plaques and tumors that can involve any site of body surface. This variant is the most common form in adulthood. Conversely, hypopigmented MF is the most common type in childhood. When clinical manifestations suggest this possible diagnosis, a skin biopsy is mandatory to formulate a conclusive diagnosis. In the classic MF histology is characterized by an epidermal invasion of atypical T-helper lymphocytes with cerebriform nuclei. Pautrier’s microabscesses, that represent epidermal lymphoid aggregates, are pathognomonic.

Narrowband UVB phototherapy is nowadays considered the first-line treatment also in children, due to his efficacy and good safety profile.
