The canine extramedullary plasmacytoma (cEMP) has recently been the subject of numerous investigations, indicating that the histomorphologic diagnosis is often difficult because of the variety of morphologic features. Therefore, the objective of this study was to establish a subclassification scheme for cEMPs and to evaluate correlations between the types(More)
Six canine, one feline and one equine granular cell tumours (GCTs) were investigated electron microscopically and immunohistochemically. The tumours were tested for reactivity with monoclonal antibodies against vimentin and desmin and with polyclonal antibodies against cytokeratin, S-100 protein, glial fibrillary acidic protein (GFAP) and neuron specific(More)
Cowpox virus (CPXV) infections are a sporadic cause of localized or disseminated skin disease in domestic animals and humans in Europe. Rodents are considered the primary reservoir host for CPXV. Cats can become infected by close contact with rodents and are the most important source of human infections. Recently, public awareness has also been drawn to(More)
Tumours of the third eyelid in 47 dogs and five cats were examined histopathologically. The clinical observations leading to the tumour diagnosis are presented. The tumours were seen more frequently in the dachshund breed, the affected cats belonged to the European Short-hair breed. The diagnosed tumours of the third eyelid could be histologically(More)
From 1983 to 1994 enucleated as well as bulbi obtained post mortem from 20 guinea pigs were ophthalmopathologically examined routinely. Eleven cases (one bilateral) with anamneses as hydrophthalmus, exophthalmus or retrobulbar abscess showed histologically osseous choristomas in the stroma of the ciliary body. In one case the osseous choristoma was already(More)
Primary (extranodal) malignant lymphoma limited exclusively to the urinary bladder is an extremely rare disorder in both humans and animals and has to be differentiated from malignant lymphoma cases where a systemic (multicentric) lymphoma has spread to the bladder. We report a case of a 3-year old female spayed mixed breed dog presenting with gross(More)
In this paper ophthalmological and clinical results as well as the literature on lens-induced uveitis (LIU), a relatively unknown pathological syndrome in domestic animals, are presented. Out of all ocular material sent to the Institute of Pathology, GSF, from 1970 until 1990 (n = 864), 40 individual cases of LIU (14 cases in dogs, 13 in cats, 10 in(More)
