Solitary luteinized follicle cyst of pregnancy and puerperium.
We report a huge ovarian solitary luteinized follicle cyst (SLFC) that contained 17 liters of fluid. Computed tomography scan revealed a 32 x 32 x 20 cm right simple cystic ovarian mass without calcification or septation. The fluid was removed, and the collapsed unilocular cyst was examined pathologically. No solid or papillary areas were identified. The cyst wall lining was composed of multiple layers of luteinized cells of variable size and shape with abundant eosinophilic cytoplasm and focally enlarged, pleomorphic, and hyperchromatic nuclei. Nests of luteinized cells were embedded within the fibrous tissue of the cyst wall. These findings are characteristic of solitary luteinized follicle cyst of pregnancy. Even though less than 15 cysts of this kind have been recorded, one should consider this uncommon, benign, non-neoplastic cystic ovarian lesion in the differential diagnosis of other cystic ovarian lesions.
