The aim of the investigation was to determine the localization, histochemical reactivity and the dimmensions of connective tissue fibers in the wall of canine paranal sinus(PS) as well as to determine the dimensions of elastic and collagen fibers. The stroma was composed mainly by collagenfibres (CF). The thicker CF were situated in the subglandular connective tissue between the apocrine glands and sinus musculare (SGS) whereas those located in the connective tissue between the sinus epithelium and apocrine glands (SES) were statistically significantly thinner. CF with a various thickness were obsserved, that decreased in the direction of epimysium of the external anal sphincter (ES) to the endomysium. The reticular fibres were assembled immediately under the multilayer squamous sinus epithelium. Yhey were located both the apocrine tubules and among the tubules. RF embedded sebaceous glands, skeletal muscle cells and smooth muscle cells. EF located in SGC and ICT were thicker and longer than those in SEC. The EF in SES were thinner and shorter compared to those in SGS.
