Dermatofibrosarcoma protuberans in an infant with a history of choroid plexus papilloma

Area of Science:

• Pediatric Oncology
• Dermatology
• Neuropathology

Background:

• Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous neoplasm typically affecting adults.
• DFSP in infants is exceptionally uncommon, with limited understanding of its pathogenesis.
• Choroid plexus papillomas are tumors arising from the choroid plexus epithelium in the brain.

Observation:

• A case report detailing an infant diagnosed with dermatofibrosarcoma protuberans (DFSP).
• The infant presented with a concurrent diagnosis of choroid plexus papilloma.
• This co-occurrence is highly unusual and warrants further investigation.

Findings:

• The presence of DFSP in an infant highlights the tumor's potential occurrence across a wider age spectrum than previously recognized.
• The simultaneous occurrence of DFSP and choroid plexus papilloma may suggest a shared underlying biological mechanism or developmental pathway.
• This case provides preliminary evidence supporting a possible neural pathogenesis for dermatofibrosarcoma protuberans.

Implications:

• This case expands the known age range for DFSP presentation.
• The findings may encourage further research into the developmental origins of DFSP, particularly exploring neuroectodermal links.
• Understanding potential neural pathogenesis could lead to novel diagnostic or therapeutic strategies for pediatric DFSP.
