Acute promyelocytic leukemia in a child with reticulin fibrosis

This report presents a case of APL in a pediatric patient in association with significant reticulin fibrosis and osteosclerosis. The case highlights that fibrosis in the marrow can make it more challenging to diagnose acute leukemia. ThePML-RARA transcripts can be present with subtle clinical or hematological findings, emphasizing the importance of molecular studies in unexplained cytopenias. Furthermore, in the case of APL, as opposed to other myeloid neoplasms, fibrosis does not appear to be associated with a worse prognosis and can resolve after treatment.
