Abstract
A case of periorbital frontal sinus osteoma in a
Jersey cow was observed at Hospital Campus,
Veterinary College and Research Institute,
Namakkal. Animal was having growth on the
periorbital region with concurrent proptosis
and ocular discharge. Space occupying lesion
was noticed on skull radiography. Representative
bony pieces were removed from the growth
for histopathology. Microscopical examination
revealed the features of osteoma which consists
of sparse population of spindle cells, few attened
cells and moderate amount of brous connective
tissue. Neoplastic cells were woven with
poorly-differentiated brocytes, chondrocytes
and osteocytes. They were dysplastic and atypical
containing centrally placed spherical nuclei.
Cells were attempting to form dense, compact
and concentric laminations. Radiography, gross
and microscopy ndings were consistent in
diagnosis of frontal sinus osteoma.
