“…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).…”

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.

“…Though cases of SCC in camels have been described, 7,8 this report is the first description in a camel of SCC of the cush pad with suspect paraneoplastic syndromes. To the authors' knowledge, no reports of haematologic paraneoplastic syndromes have been reported in camels previously.…”

“…A study out of Egypt classifying external tumours of dromedary camels showed that the majority of tumours were noticed 4 months to 2 years before presentation, with most of them presenting between 12 and 18 months after initial onset. 7 In one case, the camel had a 9-month history of proliferative cutaneous wound with a granulomatous appearance on the fetlock and progressive lameness, which were unresponsive to unspecified conventional treatment. 15 In another report of a camel with SCC of the foot, the patient presented with a 12-month history of exuberant granulation tissue on the sole of the foot that was fragile and tended to bleed.…”

“…Tumour distribution by organ among camels in Saudi Arabia and Egypt include most frequently the limbs, vagina, abdominal wall and head, 6 with most common location of cutaneous SCC on abdominal wall. 7 Though SCC has similar risk factors across species, including exposure to ultraviolet radiation and age, 9 camels in the northern latitudes likely are exposed to different risk factors than in their native habitats. Therefore, it is critical to evaluate cutaneous lesions with a systematic fashion of diagnostics and treatments, while also keeping in mind the camel's history and environmental risk factors.…”

A chronic, non‐healing, ulcerative and proliferative lesion revealed to be squamous cell carcinoma in a camel

A 20-year-old, male, neutered camel presented with an 8-month history of a proliferative and ulcerated cush pad lesion refractory to topical wound management. The referring veterinarian performed a punch biopsy to further investigate the tissue; findings were consistent with granulation tissue. The patient was referred to University of Tennessee Farm Animal Medicine and Surgery service for additional diagnostics, surgical debridement and intensive wound care. The camel underwent surgical debridement of the lesion, and histopathology was consistent with a squamous cell carcinoma. Bloodwork revealed a severe non-regenerative anaemia and leukocytosis suspected to be paraneoplastic changes. During hospitalisation, it was identified that the patient suffered from a subluxated fetlock of the left front limb and a fully dropped fetlock of the front right limb due to compensatory over-weightbearing. Due to poor prognosis of the aggressive squamous cell carcinoma associated with a severe anaemia and concomitant musculoskeletal disease, humane euthanasia was elected.

In a case of confirmed right kidney renal cell carcinoma, transrectal ultrasonography revealed a caudally protruded, large, irregular shaped, hypoechoic, and cavitated mass involving the right renal parenchyma.…”

This review article is written to describe the results of ultrasonography of the kidneys in healthy camels as well as camels with some renal disorders. In the dromedary camel, the physiology of the kidney is of interest in view of the specialization of the camel to hot dry deserts and to prolonged periods without water. It plays an important role in water conservation through the production of highly concentrated urine that may predispose animal to varieties of renal disorders. Examples of kidney affections in dromedary camels are renal capsular pigmentation, medullary hyperemia, subcapsular calcification, cortical and medullar discoloration, hemorrhage in renal pelvis, nephrolithiasis, and hydatidosis. Congestion, hemorrhage, hydronephrosis, acute glomerulonephritis, subacute glomerulonephritis, chronic glomerulonephritis, diffuse interstitial nephritis, focal interstitial nephritis, renal cyst, hyaline degeneration, renal amyloidosis, tubular nephrosis, pyelonephritis, hemosiderosis, and renal toxicity. When the kidney is examined by ultrasonography, the clinician can get sufficient information about the size, position, and echo patterns of the renal cortex and medulla and renal pelvis and outlines of the renal blood vessels. In recent years, ultrasonography has been used in camels for scanning of the healthy status as well as evaluation and determining the diagnosis and prognosis of diseased cases. Examples of diseases evaluated by ultrasonography are paratuberculosis, trypanosomiasis, pneumonia, pleurisy, gastrointestinal neoplasms, chronic peritonitis, splenic abscessation, and hepatic disorders. Of the renal disorders assessed by ultrasonography are nephrolithiasis, hydronephrosis, pyelonephritis, renal abscessation, and renal neoplasms. Ultrasound guidance in biopsy of renal specimens has also been reported in dromedary camels.
