Sir,
We report herewith a rare case of heterotopic uterine cartilage. A 45-year-old gravida six, para six female underwent hysterectomy for complaints of menorrhagia. The uterus showed a 2cm circumscribed translucent nodule located in the endometrial lining just above the uterine isthmus (Figure). The nodule could be shelled out from the adjacent tissue. Microscopy revealed a lobule of benign hyaline cartilage positioned between the endometrial lining and the myometrium. There was a cleavage plane between the cartilage and adjacent tissue. However, the cartilage edges focally showed presence of endometrial stromal cells. There was no inflammation or tumour and no other tissue was identified. A diagnosis of benign heterotopic uterine cartilage was made.
