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.
