Atypical cat scratch disease takes several different forms depending on organ systems involved. Atypical forms of disease are becoming increasingly recognized in clinical practice.
Parinaud's oculoglandular syndrome is a granulomatous conjunctivitis with concurrent swelling of the lymph node near the ear.
Optic neuritis, involvement of the retina, and neuropathy can also occur.
Bacillary angiomatosis is caused by Bartonella henselae, the causative organism of cat scratch disease. It is primarily a vascular skin lesion that may extend to bone or be present in other areas of the body. In the typical scenario, the patient has HIV or another cause of severe immune dysfunction.
Bacillary peliosis is a condition that most-often affects patients with HIV and other conditions causing severe immune compromise. The liver and spleen are primarily affected, with findings of blood-filled cystic spaces on pathology [1]
