Medical history: Since 2 months the owners have noticed that Emily has a swelling cranial to the left carpus. She otherwise shows no lameness and no dolence in this area. The increase in circumference is increasing quite rapidly. On 15.06.24 the mass was punctured by the PTA and a cyst was suspected. Three biospies were taken 3 weeks ago, the conclusion was, it is a myxoma with suspected synovial origin. One of the byopsie sites has become infected. She has been given Combiclav (amoxicilline and clavlucanic acid) against this infection until today (23.07). A CT was also carried out (report: Soft tissue cystic mass over the left carpus consistent with suspected soft tissue sarcoma (in particular myxoma, less likely myxosarcoma), No aggressive features on adjacent structures; Splenomegaly may be compatible with a benign process (extramedullary haematopoiesis, benign hyperplasia) vs.less likely to be malignant.,This lesion may also be induced by general anaesthesia (passive congestion); Bone lesions involving the radiointermediate bones of both carpals: benign and probably incidental (failure of the growth plate to close, subchondral cyst, etc.); Discrete osteoarthritis of the elbow and fragmentation of the coronoid process). Now the dog has been presented to our clinic to remove the mass (24.07.2024). After removal only a partial wound closure was possible. After two days (26.07) closure was still not possible, two new "pre-tension" sutures were made. 5 days after surgery wound revision was performed again, one new suture and release cuts were made. On the 02.08 the dog was released (under therapy with Carprofen, Sucralfat, Omeprazol and Amoxicillin / Clavulanic acid), she then came back on 06.08 to do a skin graft the following day. Bandage change was done on 10.08, 12.08 and 14.08. On the 12.08 they took a bacteriological sample during the badage change, which came back positive for Enterobacter cloacae complex on the 14.08 -> Emily was put in isolation so I couldn't film her anymore. On 16.08 a last wound revison and bandage change were done and Emily could go home. (The dog also had cystitis in mid-June, which was treated with Combiclav and Canidryl. Since then she still shows polydypsia, but no other symptoms. -> written in anamnesis at presentation. At our clinic a urine sample for culture was taken on the 09.08 but came back negative.)
