Original publication title: Diffuse heterotopic hair in a canine uterus: case report

Species:
dog

Plain-English summary

This case report discusses a female dog with an unusual condition in her uterus where there were hair follicles growing inappropriately, along with a thickening of the uterine lining due to a condition called pseudo-placentational endometrial hyperplasia (which means the uterus was behaving as if it was pregnant even though it wasn't). The dog's uterus was noticeably enlarged and had an irregular surface covered with black hairs that looked like her own. The findings were confirmed through microscopic examination. The report does not specify the treatment or outcome for the dog, so it's unclear how the situation was managed.

Abstract

The present report describes the clinical and pathological findings related to diffuse heterotopic hairs associated with pseudo-placentational endometrial hyperplasia in a canine uterus. Macroscopically, the uterus was intensely enlarged and thicker, and the endometrial surface was irregular and covered with black hairs similar to the hairs of the bitch. Histologically, heterotopic hairs associated with pseudo-placentational endometrial hyperplasia were observed.
