“…The most common tumours in dromedary camels are squamous cell carcinoma, fibroma, adenocarcinoma, fibromyxosarcoma, leiomyoma, angiosarcoma, schwannoma, lipoma, microcystic adnexal carcinoma, renal cell carcinoma, sertolileydig cell tumour and granulosa cell tumour (Tharwat et al 2017;Al-Sobayil et al 2018;Ali et al 2018;Tharwat et al 2018). In a case of gastric adenocarcinoma, transabdominal ultrasonographic examination revealed severely thickened and corrugated omaso-abomasal walls with heterogenous contents (Tharwat et al 2018) (Figure 23). In the latter case, the abomasum was enlarged at postmortem examination, its wall was thickened and hard and its contents were bloody and malodorous.…”

“…However, because of the large abdominal circumference in camels, and subacute abdominal pain even in advanced conditions, various abdominal disorders are passed misdiagnosed or detected incidentally at postmortem examination. Ultrasonography of the abdomen is applicable in camel medicine and provides valuable diagnostic information on various abdominal affections (Tharwat et al 2012a(Tharwat et al , 2012bTharwat 2013;Tharwat and Al-Sobayil 2016;Tharwat et al 2018;Tharwat 2019aTharwat , 2019b. The procedure supplements the clinical and laboratory examinations by providing additional information on abdominal disorders for diagnosis of such affections antemortem.…”

Although the diseases of the abdomen in camels (Camelus dromedaries) are frequent than those of other systems, various abdominal disorders are passed misdiagnosed or detected incidentally at postmortem examination. This may be because of the large abdominal circumference in camels, and the nature of subacute abdominal pain even in severe conditions. By abdominal ultrasonography, the veterinarian can scan the rumen, reticulum, omasum, abomasum, and small and large intestines and peritoneum in camels. Samples of peritoneal fluid can also be collected under ultrasound guidance. Sonography has been used recently in camels for scanning of the healthy organs as well as evaluation and determining the diagnosis and prognosis of diseased ones. Examples of diseases evaluated by ultrasonography are pneumonia, pleurisy, splenic abscessation, hepatic disorders, nephrolithiasis, hydronephrosis, pyelonephritis, renal abscessation and renal neoplasms. Of the abdominal disorders diagnosed by ultrasonography are intestinal obstruction, volvulus, intussusception, abdominal effusions, peritonitis, abdominal and pelvic abscessations, chronic enteritis due to paratuberculosis, and neoplasia. In such cases, ultrasonography supplements the clinical and laboratory examinations by providing additional information on abdominal disorders for diagnosis antemortem. This review article is written to describe the results of abdominal ultrasonography in healthy camels as well as in camels with some abdominal disorders.

“…In addition, there are reports of abomasal harmatomas, adenomas or adenocarcinomas in cattle ( 45 – 47 ). Abomasal adenocarcinomas have also been described in other species, including elk, guanaco or Arabian camel ( 48 – 50 ). In 2018, Tharwat et al described the case of a 15-year-old female Arabian camel suffering from an omaso-abomasal adenocarcinoma that was also associated with anorexia and severe anemia, with a PCV of 0.075 L/L similar to the goat described in the present case study ( 50 ).…”

Case Report: Severe Anemia Associated With an Abomasal Fibrosarcoma in a Goat

et al. 2022

A 10-year-old female goat was presented to the clinic with lethargy, emaciation, and pale mucous membranes. Laboratory diagnosis revealed severe anemia with regenerative character as well as melena. Blood transfusions were administered, but the animal's condition continued to deteriorate, so it was euthanized. The main finding in the necropsy was an abomasal neoplasia with two metastases in the mesenterium which was positive for vimentin, but negative for smooth muscle actin and c-kit using immunohistochemistry, indicating a fibrosarcoma that might have contributed to gastrointestinal blood loss. Further pathological findings consisted of changes in the liver cells as well as a cervical leiomyoma. These findings illustrate that intestinal blood loss due to neoplasia should also be considered in older goats with anemia.

“…Gastrointestinal neoplasms have been reported in several camels and could be the cause of similar clinical signs exhibited in our patient. 5,6 Ultrasound examination can be used to help detect sites of neoplasia. Neoplasia was deemed unlikely due to the age of the patient and ultrasound findings.…”

Recurrent colic in a 1‐year‐old dromedary camel

A 1‐year‐old male castrated dromedary camel presented with a 3‐week history of intermittent colic characterized by diarrhoea, inappetence and lethargy. The patient was originally diagnosed with intestinal parasites (Trichuris spp.) 2 weeks prior, for which he was dewormed and released from the hospital. However, the patient's clinical signs did not improve, so further workup was deemed necessary. Based on severe weight loss and hypoalbunaemia, with no further detection of common intestinal parasites, a suspicion of proliferative enteritis led to additional diagnostics. A faecal sample submitted for Lawsonia intracelluris PCR tested positive for the bacterium. The patient received four treatments of oxytetracycline, and clinical signs significantly improved. Another PCR was performed 4 weeks after treatment and was negative for L. intracellularis. While other causes of this camel's clinical signs are possible, this case suggests L. intracellularis may have contributed to signs of recurrent colic in a dromedary camel.
