Studies on bovine ocular squamous carcinoma (“cancer eye”).I. Pathological anatomy and historical review

Effects of Pigment on Bovine Ocular Squamous Carcinoma*

“…The diagnoses of lesions were in accordance with the classification of Russell et al (1956), who observed the developmental sequence of ocular carcinoma to be a continuous process. They divided the sequence of lesions developing on the bulbar conjunctiva into 3 arbitrary stages of plaque, papilloma, and carcinoma, and lesions developing on the skin of the lids were divided into keratoma and acanthosis with focal ulceration (both of which are histologically similar to plaque) and carcinoma.…”

Corneal stromal invasive squamous cell carcinoma: a retrospective morphological description in 10 horses

“…The ocular and ocular adnexal occurrence and distribution of SCCs in horses has been described in several reports 1,5,14 . This pathomorphological study is focused on a series of cases with CSI‐SCC, a variant of equine ocular SCC, which is poorly reported in the veterinary literature.…”

“…2 The ocular and ocular adnexal occurrence and distribution of SCCs in horses has been described in several reports. 1,5,14 This pathomorphological study is focused on a series of cases with CSI-SCC, a variant of equine ocular SCC, which is poorly reported in the veterinary literature. CSI-SCCs show an unusual and distinctive intrastromal growth pattern with a smooth and intact anterior corneal epithelium and Descemet's membrane in all cases.…”

“…6,13 Pathomorphologically, there exist four differentiable stages: plaque, papillomatous-exophytic lesion, non-invasive and ocular invasive lesion. [14][15][16] Individual reports exist of pigmented variants and concurrent hemangiosarcoma in the nictitans membrane as coexisting primary tumor or collision tumor. 17,18 The tumor most frequently affected the nictitans membrane, nasal canthus, limbus and eyelids.…”

Epithelial Tumours of the Skin of Sheep

“…In cattle, tumours commonly develop in and around the eye (Monlux, Anderson and Davis, 1956;Russell, Wynne and Loquvan, 1956). Some arise on the eyeball and others on the eyelids.…”
