This report described a case of NST of the DFTS caused by an abaxial fracture of lateral PSB in a 7-year-old mare used for showjumping. The mare presented with right hindlimb (RH) lameness following a field accident. Radiographic examination of the RH fetlock revealed an abaxial fracture of the plantarolateral margin of lateral PSB.

Although these tumours often demonstrate indolent biological behaviour, some progressively develop locally invasive or malignant characteristics over time, making treatment decisions challenging in clinical practice. This case series describes the clinical outcomes of intratumoural para-toluenesulfonamide (p-TLS) treatment in seven horses with cutaneous melanoma managed under field conditions. Seven horses with histopathologically confirmed melanoma were treated with intratumoural p-TLS at approximately weekly intervals, and tumour response was assessed through clinical examination, tumour measurements and serial photographic documentation. Clinical complete response was achieved in six of seven horses, while one horse showed partial response. Local tumour necrosis and sloughing developed in all cases and were followed by progressive wound healing. Mild treatment-related adverse effects, including transient local inflammation and reduced appetite, were observed but were self-limiting. Follow-up duration ranged from 107 to 765 days, with one case of local recurrence. Intratumoural p-TLS appeared to provide effective local tumour control and was generally well tolerated.

{"title":"From diarrhoea to duodenal stricture: Contrast computed tomography and portal vein gas enhance disease staging","authors":"C. A. McKinney-Aguirre,&nbsp;N. S. Browne","doi":"10.1111/eve.70113","DOIUrl":"https://doi.org/10.1111/eve.70113","url":null,"abstract":"&lt;p&gt;Enterocolitis is a common and serious problem affecting more than half of all foals before their first birthday (Mallicote et al., &lt;span&gt;2012&lt;/span&gt;; Oliver-Espinosa, &lt;span&gt;2018&lt;/span&gt;; Palmer, &lt;span&gt;1985&lt;/span&gt;). Diarrhoea, the most profound external manifestation of this disease, is the symptom that first comes to mind though, as discussed in the featured case report by Dash and colleagues, the potential for significant injury to the proximal intestinal tract should be considered well (Dash et al., &lt;span&gt;2026&lt;/span&gt;). The association of gastroduodenal ulceration and diarrhoea in foals is long established, though the exact pathophysiology of ulcerative lesions in association with colitis, and the directionality of this relationship, has not yet been elucidated (Murray et al., &lt;span&gt;1990&lt;/span&gt;; Oliver-Espinosa, &lt;span&gt;2018&lt;/span&gt;). Interestingly, it has been proposed that duodenal ulceration may occur first and beget gastric ulceration through reducing gastric outflow. Gastroduodenal damage may, in turn, progress to duodenal stricture. Regardless, for practitioners managing foals with enterocolitis, diagnostics to evaluate the stomach and duodenum for potential gastroduodenal ulcer disease (GDUD) and gastric outflow obstruction should be prioritised during initial management and especially if a foal's colic symptoms recur.&lt;/p&gt;&lt;p&gt;The aetiology of duodenal stricture remains unknown though likely is the result of local ulceration and inflammation that progresses to fibrosis and stricture (Barr, &lt;span&gt;2006&lt;/span&gt;). Pre-disposing risk factors include stress, treatment with non-steroidal anti-inflammatory medications, or intestinal disease resulting in duodenitis. As discussed by Dash and co-authors, the aetiological progression from a primary inflammatory lesion to duodenal stricture to gastric ulceration secondary to delayed gastric emptying also nicely encapsulates the distribution of the gastric ulcerative lesions in this foal, which were primarily squamous instead of glandular. As detailed by this report and a previous one, which described a 3-month-old filly with duodenal stricture, foals with GDUD and reduced gastric outflow often have a history of previous gastrointestinal syndrome, such as enterocolitis, and present with quiet demeanour, bruxism, ptyalism and nasogastric reflux (Barr, &lt;span&gt;2006&lt;/span&gt;). Notably, in most reports of GDUD, ptyalism is a very consistent clinical finding. Foal comfort will respond to gastric decompression. Dependent upon the significance of outflow obstruction, ultrasonographic evaluation will reveal an enlarged stomach and a potentially thickened duodenal wall (normal &lt;3 mm). Conveniently, the typical site for evaluation of the duodenum with ultrasound, in the right dorsal abdomen found within intercostal spaces 10–14, also facilitates evaluation of the liver (Sprayberry, &lt;span&gt;2015&lt;/span&gt;).
