In the woman’s case, doctors first noticed the hard “plaque” that had grown on the back of her left hand.
X-rays showed the flesh in her hand had swollen, while MRI scans revealed a small mass lying beneath the skin. Tissue taken from the mass showed a cluster of long “spindle” cells, which appear in a variety of different tumours.They believe it formed because of her yoga injury, with the body’s immune system overreacting to the twist.
Seven of the eight first recorded cases since HFLT were discovered in 2000 involved some sort of trauma to a hand, foot or ankle. The medics said: “Clinicians should be on high alert of similar appearing lesions that appear after various injuries, including those involving physical activity and sports.”
