The most frequent clinical signs were lethargy (n = 20; 69%) and neck ventroflexion (n = 17; 59%). Hypokalaemia was present in all cats, creatinine kinase was elevated in 15 and hyperaldosteronism was documented in 24.

Tonsillar carcinoma in dogs: Treatment outcome and potential prognostic factors in 123 cases.

Background: Tonsillar carcinomas are rarely reported in dogs. Information on outcome after treatment is sparse and prognosis is guarded to poor.

Hypothesis/objectives: Assess treatment outcome and potential prognostic factors in a population of dogs with cytological or histopathological diagnosis of tonsillar carcinoma.

Extravascular papillary endothelial hyperplasia mimicking soft tissue sarcoma in 2 cats: a potential diagnostic pitfall.

Papillary endothelial hyperplasia (PEH) is a rare soft tissue lesion arising from excessive reactive endothelial cell proliferation described in humans, dogs, and horses. PEH is considered a diagnostic challenge in humans, in which it is frequently misdiagnosed as angiosarcoma. We describe here PEH that developed at injection sites in 2 cats that were initially misdiagnosed as feline injection-site sarcoma by cytology and as subcutaneous angiosarcoma by histopathology.

Long-term survival in a cat with tonsillar squamous cell carcinoma treated with surgery and chemotherapy.

Case Summary: A 13-year-old neutered female domestic shorthair cat was presented for further investigation of a right-sided cervical mass. Oral cavity examination revealed a unilateral, right tonsillar mass. Following a contrast-enhanced CT scan of head, thorax and abdomen, which showed no clear evidence of distant metastasis, cytology of the cervical mass was consistent with a metastatic retropharyngeal lymph node, and the patient underwent tonsillectomy and lymphadenectomy.

Partial Gastrectomy at the Time of Splenectomy in Two Dogs With Splenic Neoplasia and Gastric Involvement.

Splenic malignancies are reported in 30%-76% of dogs presenting with splenic masses, and splenectomy is the cornerstone in their management. However, long term prognosis is guarded due to the high rates of distant metastases reported both for HSA and nonangiogenic nonlymphomatous sarcomas. Metastases from splenic tumors usually occur to regional lymph nodes, liver, omentum, and lungs.

Incidence of postoperative complications and outcome of 48 dogs undergoing surgical management of insulinoma.

Background: Information regarding outcome of dogs undergoing surgical management for insulinoma is based on studies of a small number of dogs.

Objectives: To report the outcomes of dogs undergoing surgery as treatment for insulinoma, the prevalence of postoperative diabetes mellitus (DM) in this group and to determine if development of DM can be predicted.

Animals: Forty-eight client-owned dogs, with a histopathological diagnosis of insulinoma, from three European referral hospitals.

Retrospective comparison of first-line adjuvant anthracycline vs metronomic-based chemotherapy protocols in the treatment of stage I and II canine splenic haemangiosarcoma.

Splenectomy followed by adjuvant chemotherapy is commonly used to treat canine splenic haemangiosarcoma (HSA), although it is unclear if different treatment protocols may have a similar efficacy. The objective of this retrospective study was to assess outcome in dogs with stage I and II splenic HSA treated with either first-line adjuvant anthracycline (AC) or metronomic (MC)-based chemotherapy protocols, by comparing median time to progression (TTP) and median survival time (MST). Medical records of nine institutions were searched for dogs diagnosed with stage I and II splenic HSA that underwent adjuvant treatment with AC- or MC-based protocols following splenectomy.

Neoadjuvant and adjuvant doxorubicin chemotherapy in a case of feline soft tissue sarcoma.

Case Summary: A 7-year old male neutered domestic shorthair cat was presented with a 2 month history of a slow-growing mass on the right zygomatic area. A CT scan revealed a soft tissue mass in the right zygomatic region with no alterations of the underlying bone and features of local invasiveness. Cytology was suggestive of a mesenchymal tumour and histopathology from an incisional biopsy was consistent with a soft tissue sarcoma (STS).

Pheochromocytoma in Dogs Undergoing Adrenalectomy.

Pheochromocytoma is frequent in dogs and carries a guarded prognosis. Current histological criteria may not predict malignant behavior in dogs, similar to humans. In humans, characterization of tumors has been refined using the pheochromocytoma of the adrenal gland scaled score (PASS) and by immunohistochemistry.

Use of a coccygeal axial pattern flap for reconstruction following tumour excision in a cat.

A 6-year-old male castrated Chartreux cat was referred for recurrence of an injection site sarcoma at the base of the tail 7 months after the initial surgery. Upon presentation, the physical examination was unremarkable except for a non-painful, subcutaneous mass, 2 cm in diameter, firmly attached to the underlying tissue on the left lateral side of the tail base. Complete blood count, biochemistry and urinalysis were within normal limits; thoracic radiographs and abdominal ultrasound showed no evidence of metastatic disease.
