Parinaud's oculoglandular syndrome: Coinfection by Bartonella henselae and Sporothrix brasiliensis

Abstract

A 26-year-old woman presented an eyelid lesion, after being scratched by a cat that had a similar skin lesion. It evolved into a cervical lymph node enlargement. With a hypothesis of Parinaud´s oculoglandular syndrome (POS) due to cat scratch disease (CSD), doxycycline was prescribed. After two weeks of treatment without improvement, a biopsy and blood sample were obtained. Itraconazole was prescribed and the skin lesion improved, but not the lymph node enlargement. A Sporothrix schenckii complex was isolated from the skin sample. Also, a specie-specific polymerase chain reaction detected Bartonella henselae DNA in her blood sample. Azithromycin was included to treat the bacterial infection, whereupon the lymph node also receded successfully. Sporotrichosis and CSD are zoonoses that can be transmitted to humans by traumatic inoculation due to scratches or bites from cats. Both can evolve with POS. Patients who present skin lesions and/or POS after being wounded by a cat should be investigated for both diseases.
