Osseous metaplasia of the endometrium

Retained fetal bone post‐abortion causing infertility

Fetal bone retention is a rare but under‐diagnosed complication after abortion. If left untreated, it can cause menstrual dysfunction and secondary infertility. We present a case of a 39‐year‐old woman who undergone abortion 20 years ago but suffered with secondary infertility due to retained fetal bone.

Retained fetal bone is a rare complication for abortion and can cause secondary infertility. There is currently no comprehensive guidance in abortion care in the UK regarding this complication, hence we call for awareness and development of guideline.

Osseous Metaplasia in Low-grade Ovarian Serous Carcinoma With a BRAF Mutation: A Case Report

A 44-yr-old woman presented with lower, painless abdominal discomfort and a vacuolated mass measuring 12 cm on the right-hand side of the pelvis. She subsequently underwent a bilateral salpingo-oophorectomy. An osseous lesion was identified in the left ovary, which was hard in consistency and was associated with a multicystic complex lesion. Microscopic examination of the left ovary showed clusters of serous cells with moderate atypia, surrounded by a desmoplastic stroma with large areas of bone matrix. To the best of our knowledge, this is the first reported case of low-grade serous carcinoma with osseous metaplasia and a BRAF mutation.
