Plain-English summary
A crossbred cat developed a lump on the left side of its chest after receiving a vaccine for feline parvo, herpes, and calicivirus. A few months later, another lump appeared on the right side after a booster shot was given at that site. These lumps were identified as fibrosarcomas, a type of tumor that can sometimes occur at vaccination sites. This case suggests that some cats may be more prone to developing these tumors after vaccinations. The cat's veterinarian will likely monitor the situation closely and may recommend further treatment or management options.

Abstract
A crossbred cat developed a subcutaneous fibrosarcoma on the left side of the thorax at the site of previous administration of a feline parvo-, herpes- and calicivirus vaccine. A few months later the cat developed a second mass on the right side of the thorax after a booster vaccine had been administered at this site. This unique case of bilateral fibrosarcomas in a cat shortly after vaccination with parvo-, herpes- and caliciviruses suggests an individual disposition for the development of vaccine-associated sarcomas and a possible triggering of this type of pathological response which could have precipitated the development of the second tumour. To the authors' knowledge, this is the first case of vaccine-induced fibrosarcomas occurring bilaterally after injection of a feline parvo-, herpes- and calicivirus containing vaccine at different sides of the thorax.
