Ovarian microcystic stromal tumor with undetermined potential: Case study with molecular analysis and literature review

Ovarian microcystic stromal tumor is a relatively rare tumor type. This tumor is characterized by a unique microcyst structure and essentially all tumors show benign biological behavior. Here, we report a case with a primary ovarian microcystic stromal tumor that experienced recurrence. Pathological findings showed that the original tumor, relapsed tumor in the ovary, and the recurrent tumor in the iliac fossa presented similar histological features. The tumor mainly consisted of microcysts, solid cellular regions, and a fibrous stroma.
