Abstract
Three cases of leukemic dermal infiltrates at permanent indwelling central venous catheter insertion sites in patients with acute myelogenous leukemia are reported. Two patients had a localized soft tissue mass at the previous permanent indwelling catheter insertion site as the sole initial manifestation of relapse after achieving complete remission and undergoing bone marrow transplantation. The third patient had catheter tunnel sepsis preceding leukemic dermal infiltration. A review of the English language literature showed that this condition is rare with no specific pathogenetic mechanisms identified. Patients with unresolved catheter tunnel infections in acute leukemia and persistent chest wall masses that appear after a previous permanent indwelling catheter should have a biopsy done and be treated promptly.
