Most importantly, they found that young patients rarely (3 patients out of 76) developed skin tumor lesions and none progressed into lymph glands, organs or blood. They found that most children and teenagers with MF had limited patch disease involving less than 10% of the skin. Guitart’s team at Northwestern University who followed more than 100 children with MF. These data are in line with our experience at our centers and the recent findings researched by Dr. However, data from retrospective studies suggest that the outcome of CTCL in childhood seems rather better compared to adults when monitored over a median time period of 9 years. None of the published studies have been large enough to assess prognosis and outcome in childhood. Of note, most young patients were found to have early stage disease without spread into blood, lymph nodes or organs. When these patches were biopsied and stained for certain lymphocyte (white blood cell) markers, the initial manifestation of MF was characterized by the presence of CD8+ T-cell phenotype, unlike the CD4+ T- cell phenotype usually encountered in MF. Investigators found that most young patients presented with white or very light-colored, so-called “hypopigmented” patches on the skin. It has only been in the last several years that investigators have truly begun to understand the characteristics of pediatric presentations of cutaneous lymphoma as more data has become available.Ī few studies have described the clinical and pathological aspects of MF in children and adolescents. The prognosis for children is similar to adults. For these reasons, diagnosis in children is often delayed much longer than in adults. The challenges of diagnosing and treating such complex and often ambiguous diseases are magnified by parents’ concerns, expectations, and a child’s own level of understanding.Īnother complicating factor is that the medical community is usually hesitant to perform biopsies on children unless there is absolute indication of the presence of this disease – and biopsy is the best way to firmly diagnose cutaneous lymphoma. When children have chronic inflammatory dermatitis, which are ongoing skin conditions that are not classified with a certain diagnosis (an unusual presentation of psoriasis, eczema or atopic dermatitis), physicians must consider the possibility of mycosis fungoides. One of the most common misdiagnosis is “ringworm”. This is further complicated by the fact that MF may clinically simulate benign rashes, in particular atopic dermatitis, eczema or vitiligo. However, due to its uncommon manifestation in young patients, the diagnosis of cutaneous lymphoma is often delayed or missed. Upcoming Events for Medical ProfessionalsĪmong children, the distinguishing features of this disease can be misleading, making it ever more difficult to diagnose cutaneous lymphoma in children. Mycosis fungoides (MF) is the most frequently diagnosed primary cutaneous lymphoma in childhood other than lymphomatoid papulosis. ![]()
