An unusual Bartonella henselae infection presenting clinically as a putativ
e parotid cancer was diagnosed based on serological tests, histomorphology
and amplification of a 16S-rDNA sequence of Bartonella henselae. The patien
t improved greatly upon antibiotic treatment and did not require surgery. A
lthough uncommon, infection with Bartonella spp., particularly Bartonella h
enselae, should be included in the differential diagnosis of parotid tumors
.
