Abstract:
A seven years old female German Shepherd dog was presented with a spherical hard mass in the limb. For cytologic identification of the mass, sample was collected by Fine needle aspiration cytology (FNAC). Cytologic examination revealed sparse spindle shaped cells containing oval to elongated nuclei with indistinct cytoplasm. Histopathologic examination of the mass revealed interlacing bundles of spindle shaped fibroblasts with elongated, oval nuclei and indistinct nucleoli. Picro sirius red special stain revealed the presence of red coloured interlacing bundles of spindle shaped fibroblasts. Based on the above findings, the mass was diagnosed as fibroma.
