Two patients with tendinitis by ciprofloxacin are described. In both p
atients isolated involvement of the Aquilles tendon was produced. The
symptoms initiated at 2 to 4 weeks of the begining of treatment. The t
wo patients had undergone chemotherapy and bone marrow transplantation
due to chronic myeloid leukemia and acute promyelocytic leukemia, res
pectively with no data on recurrence of leukemia being obtained at the
time of the tendinitis. Suppression of ciprofloxacin achieved disappe
arance of the symptomatology.
