“…In veterinary oncology, assessment of the nodal status mainly relies on the palpation of the accessible regional lymph nodes and when available transectional imaging to identify enlarged or rounded lymph nodes . Lymph nodes in body cavities or of the neck are assessed with ultrasound or CT, but are often only sampled (usually with fine needle aspiration) when grossly abnormal.…”

This study reports the clinical value of sentinel lymph node (SLN) mapping with indirect lymphography (IL) using iodized oil (IO) as a marker injected preoperatively around the site of the primary tumour and radiography or tomodensitometry for imaging. Surgical extirpation of the node was performed following peritumoural injection of methylene blue (MB). Twenty nine dogs affected by 30 palpable solid tumours were prospectively studied. SLNs were identified by IL in 96.6% of the IL studies. IL followed by MB studies were performed in 25 dogs (26 studies). In these studies, agreement between IL and MB was observed in 84.6%. One dog had a minor complication following IO injection. This protocol represents an attractive alternative to scintigraphy for SLN mapping. This less technically demanding protocol may provide a wider access to SLN identification for application in veterinary oncology.

“…The CT scan and US examination supported the diagnosis of thyroid carcinoma given the location, CT18 and US19 appearance of a thyroid carcinoma. However, neither a CT nor an US scan are 100 per cent specific for this or any histological type of tumour 20. While HSA can have a few precontrast and postcontrast CT morphological characteristics similar to a thyroid carcinoma, such as attenuation or texture, cavitation and intratumoural vascularisation, thyroid carcinomas can also have a varying appearance on CT examination 18 21.…”

Canine thyroid tumours are uncommon and the majority of tumours are carcinomas or adenomas, with only very few mixed tumours or metastases from distant sites described to date. A primary thyroid haemangiosarcoma has never been reported in veterinary medicine. In this case report, we describe a dog with a history of a large, non-painful, mobile ventral neck mass in the right paralaryngeal region. CT and ultrasound-guided fine needle aspirates were used for clinical staging. The mass was surgically excised and histopathological examination indicated a haemangiosarcoma. Abdominal ultrasound revealed the presence of splenic nodules and splenectomy indicated the presence of haemangiosarcoma. Chemotherapy with doxorubicin was started, but the dog was euthanased after three rounds of therapy, 97 days after the mass was discovered.

“…Mesenchymal tumours, such as leiomyoma, leiomyosarcoma and gastrointestinal stromal tumours (GISTs), have a similar cytological and histological appearance. [3][4][5][6] Aspirates of these tumours are often highly cellular and consist of long, thin mesenchymal cells with 'cigar-shaped' nuclei arranged in aggregates and linear bundles. [3][4][5][6][7][8] The most common locations for smooth muscle tumours in cats include gastrointestinal, cutaneous and the female reproductive tract.…”

A female spayed domestic longhair cat aged 3 years and 9 months was referred for investigation of regurgitation and weight loss of 2 months' duration. Thoracic radiographs revealed a soft tissue mass within the cranial mediastinum causing focal oesophageal dilation. Computed tomography confirmed a contrast-enhancing mass located cranial to the heart base, possibly originating from the oesophagus. Exploratory thoracotomy revealed an intramural soft tissue mass within the ventral oesophageal wall. Surgical excision of the mass and reconstruction of the oesophagus around an oesophageal tube was performed successfully. Histopathological examination of the mass was compatible with a spindle cell tumour with a prominent vasoformative component. Immunohistochemistry was positive for α-smooth muscle actin and von Willebrand factor protein, and negative for CD117/c-kit protein. Both histopathological and immunohistochemical findings confirmed the diagnosis of an angioleiomyosarcoma. The cat was clinically well 6 months postoperatively. To our knowledge, this is the first report of an oesophageal angioleiomyosarcoma in a cat.
