| The lymph node is replaced by pyogenic granuloma-like small vessel proliferation (HE, low power). The disease was first described as multiple skin lesions in 1987. The liver and spleen may also be the target of this opportunistic infeciton of Bartonella henselae. | Around small vessels, deposition of granular eosinophilic material resembling fibrin is observed (HE). In the deposits, short rods are demonstrated by Warthin-Starry's silver or by electron microscopy. | |
