Presence of sheets of epithelioid cells with lymphocytes and plasma cells with or without multinucleated giant cells were diagnosed as granulomatous lymphadenitis, and eosinophilic granular material containing inflammatory cells and necrotic cell debris was defined as caseous
granulomas were detected in females especially.
On clinical examination, all dogs having aural hematoma except one showed apparently healthy ear canal, one dog with bilateral aural hematoma showed caseous
purulent discharge with ceruminoliths.
Abattoir survey caseous
lymphadenitis in sheep and goats in Tanta, Egypt.
Right cervical lymph node excisional biopsy was then performed and pathology revealed caseous

2) The pathologic hallmark of sarcoidosis is the presence of granulomatous inflammation without central caseous
Histopathological examination revealed caseous
ve granulomatous infection compatible with tuberculosis.
Histologically, the mature tuberculomas are composed of caseous
necrosis center surrounded by a capsule that contains fibroblasts, epithelioid cells, Langhans giant cells, and lymphocytes .
On opening the carcasses, typical IBD lesions were observed; they included enlarged BFs which were also oedematous, haemorrhagic, and sometimes necrotic and atrophied, with caseous
cheesy exudates in the mucosa, haemorrhages in the thigh, leg, and breast muscles, proventriculus, caecal tonsils, thymus, and spleen.
Dry peritonitis (with caseous
nodules and adhesions without ascites) was seen in 7 (34%) patients.
Elevating the cartilage flap over the lesion revealed caseous
grayish-white tissue, which was entirely curetted out, leaving an unfilled crater over which the joint cartilage was simply laid without need for any suture.
1,4,5) Prostatic TB often presents as diffuse caseous
necrosis with calcifications and the development of fibrosis with gland hardening; however, it is usually asymptomatic.
