Occurrence of haemangiosarcoma on the gingiva of a calf: a case report

Abstract

Haemangiosarcoma is a malignant endothelial cell tumour with rapid growth and poor prognosis. In animals, haemangiosarcoma is frequently reported in dogs as a visceral tumour. The present study describes a gingival haemangiosarcoma in a 2-month-old, female native breed calf with a tumour likemass on the gingiva. The owner had noticed the mass 2 weeks after birth due to salivation, bleeding and halitosis. It had rapid growth and caused anorexia and weight loss in the animal. Histopathologic examination showed a lot of thin-walled, irregular blood vessels lined by a single and less commonly two layers of endothelial cells. The lining cells were with spindle or ovoid shape with vesicular to hyperchromatic nuclei and prominent nucleoli. There were remarkable thrombi in some vessels. The reported lesions were diagnosed as haemangiosarcoma based on histopathologic characteristics such as irregular vascular canals and polymorphism of neoplastic endothelial cells. Haemangiosarcoma is rare in the oral cavity of cattle.

Acute coenurosis in lambs

“…C. cerebralis lives in brain, visceral organs, muscle and subcutaneous tissue of the intermediate hosts (sheep, goat, cow, camel, yak, wild sheep, human, deer, pig and horse) (Azizi et al., 2019). Coenurosis has two forms, that is acute and chronic, whose chronic form is much more common and is caused by cerebral, visceral, muscular and subcutaneous C. cerebralis cysts containing cluster protoscoleces (Azizi et al., 2019; Christodoulopoulos et al., 2016; Varcasia et al., 2022). The acute form of coenurosis is rare and occurs due to simultaneous cerebral migration of large numbers of C. cerebralis oncospheres (larvae less than 5 mm in diameter) (Abera et al., 2016; Varcasia et al., 2022).…”

“…M. multiceps lives in small intestine of the definitive host's (dog and wild Canidae). C. cerebralis lives in brain, visceral organs, muscle and subcutaneous tissue of the intermediate hosts (sheep, goat, cow, camel, yak, wild sheep, human, deer, pig and horse) (Azizi et al, 2019). Coenurosis has two forms, that is acute and chronic, whose chronic form is much more common and is caused by cerebral, visceral, muscular and subcutaneous C. cerebralis cysts containing cluster protoscoleces (Azizi et al, 2019;Christodoulopoulos et al, 2016; from their mother 20 days ago, and taken to the new farm for fattening in a semi-intensive system.…”

Clinical examinations of the affected lambs showed cachexia, bilateral blindness, stupor (Figure 1a), severe drowsiness and lethargy with left and right movements of the head and neck after awakening and stimulation.…”
