A 4 month old unneutered male cat was presented at the Veterinary Teaching Hospital of Iasi, with severe dermal lacerations on the posterior side of the right thigh, up to the last rib of the right hemithorax and opened fracture of the right femoral proximal epiphysis, wounds induced by a profound dog bite. The cat underwent reconstructive surgery of the femoral fracture and dermal laceration, full recovery lasting up to three weeks. After the complete healing of lesions, four weeks later, the cat was presented again for consultation, presenting multiple dermal ulcers developing rapidly over 24h on the left thigh, at the marginal limit of the initial dermal laceration. The owner did not report any other changes in the general state of the cat. Physical examination revealed indurated masses of the subcutaneous tissues, with pockets containing reddish-brown exudate. Cytological examination of exudate sampled from a superficial sight of the formation indicated a granular proteic fond, with numerous neutrophils and macrophages. Cytological and microbiological diagnosis was performed on samples collected from a profound sight of the subcutaneous pockets. Microbiological tests isolated and identified Nocardia spp. as pathogen. The exact nocardial species will be further confirmed by polymerase chain reaction analysis and gene sequencing. Antimicrobial drug of choice in this case was erythromycin, administered parenterally for ten days and continued by oral therapy up to 12 months to prevent relapse.
