Botriomycomas are frequent benign tumors in children. Their appearance on the central catheter orifice is a known event in clinical practice, but one that has been little studied. This lesion could lead to changes in pathways and an increase in the number of sepsis events, which would promote thrombosis and thus depletion of venous capital in patients who have been dependent on a central line for many years.

This study is a pilot study which will enable us to better identify the risk factors for the development of such a tumour, and to take stock of the different treatments used and their respective efficacy.

Inclusion Criteria:

• home parenteral nutrition patients
• never diagnosed with an episode of botriomycoma on their central line
• 0 to 18 years of age at diagnosis

Exclusion Criteria:

• Botriomycoma more than 10 years old at time of data collection (or lack of data)
• Patient over 18 years of age
• Not on home parenteral nutrition patients
