Capillary Refill Time & Rhabdomyosarcoma in Infant
- A 20-month-old female infant presented with a markedly prolonged capillary refill time specifically in her right foot.
- The prolonged capillary refill time was ultimately associated with a diagnosis of rhabdomyosarcoma, a rare type of cancer that develops from skeletal muscle cells.
- Capillary refill time is a speedy, non-invasive clinical assessment used to evaluate peripheral perfusion.

Clinical Presentation
A 20-month-old female infant presented with a markedly prolonged capillary refill time specifically in her right foot. This finding, observed during a clinical evaluation, raised concerns and prompted further investigation into potential underlying causes.
Diagnosis and Association with Rhabdomyosarcoma
The prolonged capillary refill time was ultimately associated with a diagnosis of rhabdomyosarcoma, a rare type of cancer that develops from skeletal muscle cells. Rhabdomyosarcoma can present in various ways, and peripheral circulatory changes, such as delayed capillary refill, can be an indicator of the disease’s impact on local blood flow or potential metastatic involvement.
Meaning of Capillary Refill Time
Capillary refill time is a speedy, non-invasive clinical assessment used to evaluate peripheral perfusion. A normal capillary refill time is generally less than two seconds. Prolongation can suggest decreased blood flow, potentially due to vasoconstriction, hypovolemia, or, as in this case, a localized obstruction or infiltration caused by a tumor.
Implications for Pediatric Oncology
This case highlights the importance of considering rhabdomyosarcoma in the differential diagnosis of infants and young children presenting with unexplained peripheral circulatory abnormalities. early detection and diagnosis are crucial for optimizing treatment outcomes in pediatric oncology cases. Further research is needed to fully understand the mechanisms linking rhabdomyosarcoma and alterations in peripheral perfusion.
