Although Bartonella henselae is the commonest cause of POGS, Sporothrix schenckii warrants consideration in cat-exposed patients, alongside bacterial co-infection.
Abstract
A 41-year-old woman developed chronic unilateral granulomatous conjunctivitis, ipsilateral lymphadenopathy, fever and malaise, diagnostic of Parinaud oculoglandular syndrome, after contact with a sick pet cat. Tear cultures identified Sporothrix schenckii, confirmed by 18S ribosomal RNA PCR, with co-infection by Moraxella osloensis. Biopsy showed suppurative necrotising granulomatous inflammation. Oral itraconazole, topical amphotericin B and amikacin achieved remission. Although Bartonella henselae is the commonest cause of POGS, Sporothrix schenckii warrants consideration in cat-exposed patients, alongside bacterial co-infection.
