Hand-foot syndrome induced changes of the palmar epidermal ridge configurations during and after treatment with capecitabine.

Palmar plantar erythrodysesthesia (hand-foot syndrome, HFS) is a common adverse event of treatment with cytostatic chemotherapeutics such as capecitabine. Histopathological findings are nonspecific and may even include generalized epidermal necrolysis. A total of 50 patients were examined before and after the intake of capecitabine to assess if HFS may result in relevant changes of the palmar epidermal ridge configurations with possible consequences for the patients who want to travel abroad. In total, 14 of the 50 patients developed HFS (28%) with HFS grades 1-3 observed. HFS grade 4 was not observed. HFS of grade 2 and 3 was associated with a temporary macroscopic loss of the epidermal ridges. No dactyloscopic changes that might have led to a false identification were seen in those cases. Patients with a risk of HFS development who want to travel abroad should carry a medical pass of the chemotherapeutic treatment to prevent them from difficulties in identification controls.
