A 25-yr-old, nulliparous, female Przewalski's wild horse (Equus ferus przewalskii) with a history of pituitary pars intermedia dysfunction and recent onset of serosanguinous vaginal discharge was euthanized after a period of lethargy and inappetance. Postmortem examination confirmed an infiltrative uterine adenocarcinoma, which is an uncommon neoplasia in equids. Reproductive disease is significant in this species as they are considered endangered by IUCN. Reproductive soundness and success are paramount to conservation efforts.

The present study reports the case of a 71-year-old female with metastatic adenocarcinoma of the skin who developed tumor lysis syndrome (TLS) upon admittance to the First Affiliated Hospital of Liaoning Medical University (Jinzhou, China). The patient presented to the hospital due to multiple subcutaneous nodules, lethargy and weakness, but succumbed without any cancer therapy. Metastases to the skin from solid carcinomas are uncommon, and several studies have reported patients with minimal primary symptoms despite extensive metastatic skin disease. However, few cases were accompanied with spontaneous TLS at the time of presentation. TLS may be a severe complication during the therapy for hematological and oncological diseases. Although spontaneous TLS in internal tumors has been reported, it is extremely rare. The present study highlights the fact that multiple subcutaneous metastases may occur with the symptoms of spontaneous TLS, and may be key for the early recognition of this syndrome.

A 7-yr-old, intact, female swift fox (Vulpes velox) presented to the Veterinary Health Center at Kansas State University with a history of chronic weight loss, lethargy, inappetence, and myiasis. On physical examination, a firm mass was palpated in the mid- to cranial abdomen. The fox was euthanatized as a result of the grave prognosis. Gross necropsy and histologic findings included a small intestinal adenocarcinoma with diffuse transperitoneal spread throughout the abdominal cavity (carcinomatosis). To the authors' knowledge, this is the first report of intestinal adenocarcinoma with carcinomatosis in a swift fox.

A 7-yr-old male Major Mitchell's cockatoo (Lophochroa leadbeateri) presented with a recent history of lethargy and anorexia. Physical examination revealed poor body condition and cloacal prolapse. Abnormalities on serum chemistry included severe hyperuricemia and hyperphosphatemia with a low calcium-to-phosphorus ratio. Symptomatic treatment was initiated including intravenous fluids and antibiotics. The bird continued to decline and died within a few days. Visceral gout and renal and cloacal pathology were observed on gross necropsy. Histopathology revealed chronic inflammation within the kidney, ureter, and cloaca in association with protozoal organisms and an invasive cloacal adenocarcinoma tumor. The location and morphology was consistent with Cryptosporidium sp., confirmed by immunohistochemistry and molecular testing. Direct sequencing identified Cryptosporidium avian genotype V. To the author's knowledge, this is the first reported infection of Cryptosporidium avian genotype V associated with clinical disease in birds and the first renal Cryptosporidium infection in a psittacine.

A 5-year-old female entire German Shepherd presented for otitis and lethargy. An incidental abdominal mass was identified on examination. Ultrasound examination (US) identified a heterogeneous left ovarian mass. Computed tomography (CT) was performed for surgical planning and staging. The reproductive tract was removed en bloc and submitted for histopathology. Multiple small (1-5 mm) nodules identified at coeliotomy on the surface of the liver, spleen and peritoneum were biopsied. The lesions were not visible on CT nor US on review. This is the first case report of the CT findings of ovarian papillary adenocarcinoma with carcinomatosis.

CASE DESCRIPTION 5 dogs between 9 and 11 years of age were evaluated for treatment of primary (n = 2) or metastatic (3) hepatic neoplasia. CLINICAL FINDINGS Patients were evaluated on an elective (n = 3) or emergency (2) basis. Two dogs with primary hepatic neoplasia were evaluated because of lethargy and inappetence. One dog was referred after an enlarged anal sac was detected via palpation per rectum during a routine physical examination. Two dogs were evaluated on an emergency basis because of lethargy and weakness, and hemoabdomen in the absence of a history of trauma was detected. All 5 dogs underwent thoracic radiography and abdominal ultrasonography, with CT performed in both dogs with primary hepatic neoplasia. All dogs had preoperative evidence of abdominal neoplasia, and none had evidence of thoracic metastasis. TREATMENT AND OUTCOME All dogs underwent ventral midline laparotomy and had diffuse hepatic neoplasia that precluded complete resection. Locoregional treatment with MWA was applied to hepatic lesions (0.5 to 2.5 cm diameter) without procedural complications. Histopathologic diagnoses were biliary adenocarcinoma (n = 1), hemangiosarcoma (2), hepatocellular carcinoma (1), and apocrine gland adenocarcinoma (1). CLINICAL RELEVANCE MWA is being increasingly used as an adjunct in the surgical treatment of human patients with primary and metastatic liver disease. Results of the present small case series suggested that MWA is feasible and potentially effective as an adjunctive treatment for appropriately selected dogs with nonresectable hepatic tumors. Further investigation is indicated.

A 52-yr-old female Nile hippopotamus ( Hippopotamus amphibious ) was presented for acute onset anorexia, depression, lethargy, instability, and weakness in the pelvic limbs. Clinical signs were rapidly progressive, despite empiric therapy with anti-inflammatory medications, resulting in the death of the animal. Gross necropsy evaluation revealed two tan, firm masses in the cerebellum and mesencephalon and a single mass in the right cranial adrenal gland. All three masses had a similar histologic morphology, and immunohistochemical investigation confirmed the general diagnosis of an adenocarcinoma, but the exact cell of origin remains unclear. In addition, there was evidence of neuroendocrine differentiation in the adrenal gland and not in the brain. These findings suggest either two distinct neoplastic populations or a metastasizing adenocarcinoma with focal endocrine differentiation. In dogs, anal sac and clitoral adenocarcinomas have been reported to undergo focal endocrine differentiation, and both can cause widespread metastasis while the primary lesion can be small. A small neoplasm of these glands may have been missed on gross examination.

A 6-year-old female neutered European Shorthair cat was presented with a 2-day history of lethargy and hyporexia. On physical examination, the cat was slightly depressed and had a 2.5 cm nodule in the left 3rd mammary gland. The hemogram revealed mild leukocytosis with mature neutrophilia and moderate thrombocytopenia. On blood smear evaluation, rare pleomorphic cells, possibly of epithelial origin, were observed mainly at the feathered edge. The animal died about 12 hours after presentation, and a necropsy was performed. On histopathology, the mammary nodule was diagnosed as a tubulopapillary adenocarcinoma with vascular invasion and widespread metastases. Immunocytochemical tests for cytokeratins (AE1/AE3) confirmed the epithelial phenotype of the neoplastic cells observed on the blood smear. The present report describes a feline mammary carcinoma with widespread metastases and the presence of malignant epithelial cells in the peripheral blood referred to as carcinocythemia. This condition has been previously described in people and dogs. To the author's knowledge, this is the first reported case of feline carcinocythemia. As in other species, the phenomenon was associated with a terminal phase of systemic malignancy.

A free-ranging juvenile California sea lion ( Zalophus californianus) stranded on the coast of Vancouver, British Columbia, with signs of lethargy and emaciation in April 2016. An asymmetrical skull with a prominent superficial cervical lymph node was found on initial assessment. Fine-needle aspirates and biopsies of the lymph node were consistent with neoplasia and the animal was humanely euthanized and presented for necropsy. A metastatic parotid gland adenocarcinoma was diagnosed with regional lymph node and pulmonary metastases. Local invasion of contiguous skeletal muscle, bone, ear, and tonsils was extensive and likely accounted for the unilateral craniofacial deformity. Neoplasia of nonurogenital origin in juvenile California sea lions are reported infrequently. This is the first case of a parotid carcinoma in a California sea lion.

Ovarian teratomas are occasionally reported in dogs; the rarest type is the monophasic teratoma, composed of tissues originating from only one germ layer. Canine endometrial adenocarcinomas are also rare in dogs and mainly affect geriatric females. This report describes the case of co-existing ovarian teratoma and uterine adenocarcinoma in a 10-year-old nulliparous female Boxer presented with lethargy, anorexia and purulent vaginal discharge. Abdominal ultrasonography evidenced pyometra and a mass in the left ovary. This was composed of a uniform whitish tissue with multiple cystic structures. The histology revealed an atrophy of the ovarian parenchyma, compressed by a proliferation of well-differentiated nervous tissue staining positively to vimentin, S100 and neuronal specific enolase (NSE), and negatively to keratin and inhibin. The left uterine horn, whose diameter was markedly increased, showed foci of endometrial cellular atypia, evident nucleoli and mitoses, at light microscopy. To our best knowledge, this is the first report of a co-existing ovarian monophasic teratoma and endometrial adenocarcinoma, two rare reproductive neoplasia in dogs.
