Hepatitis in association with rickettsialpox.

Rickettsialpox is an acute, self-limited, febrile illness caused by Rickettsia akari and transmitted by Liponyssoides sanguineus, a mite that infests the common house mouse, Mus musculus. Liver involvement in rickettsialpox has received little attention, although hepatitis has been reported in several other rickettsial infections. In this report, we describe two patients with rickettsialpox who had acute hepatitis that resolved completely. In the appropriate clinical setting, rickettsialpox should be considered in the differential diagnosis of hepatitis.
