Insights
Diagnosing cutaneous T-cell lymphoma (CTCL) in children is often delayed, especially in infants. Early consideration of CTCL in chronic skin conditions is crucial for timely diagnosis in pediatric patients.
Area of Science:
- Dermatology
- Pediatric Oncology
- Hematology
Background:
- Mycosis fungoides (MF), the most common type of cutaneous T-cell lymphoma (CTCL), primarily affects adults.
- Pediatric cases of CTCL are rare, necessitating a review of existing literature.
Observation:
- A literature review identified 254 pediatric CTCL cases (age <16 years).
- Only seven CTCL cases were reported in infants under one year old.
- The youngest age group (0-3 years) experienced the longest diagnostic delay.
Findings:
- CTCL prevalence in children peaks between ages 10-12 years.
- Diagnostic delays in pediatric CTCL decrease with increasing patient age.
- Delayed diagnosis is most pronounced in the youngest pediatric patients.
Implications:
- CTCL diagnosis is frequently delayed in young children.
- Consider CTCL in infants and children with chronic 'eczematous' skin lesions.
- Increased awareness of CTCL is needed for pediatric skin conditions regardless of age.
Background:
Mycosis fungoides (MF), the most common form of cutaneous T-cell lymphoma (CTCL), is mainly a disease of the elderly.
Objectives:
To review paediatric CTCL cases reported in the literature, with a focus on the time between onset of symptoms and establishment of a correct diagnosis.
Methods:
A review of the literature was carried out and a case reported.
Results:
A total of 254 cases of CTCL have been reported in children aged<16 years, 13 cases (<1% of all reported cases) in children below the age of 2 years, and only seven cases (including ours) during the first year of life. CTCL was most prevalent in children aged 10-12 years. The delay between age of onset and establishment of diagnosis was largest in the youngest age group (0-3 years), and declined steadily thereafter, thus reflecting the increasing likelihood that CTCL is considered in the differential diagnosis of skin disorders with increasing age of the patient.
Conclusions:
The diagnosis of CTCL is frequently delayed in young children. It needs to be considered in chronic 'eczematous' skin lesions irrespective of the patient's age, and including infants.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
