Multilocular peritoneal inclusion cysts (MPIC) are an infrequent postperative complication and are characterized by frequent intra-abdominal recurrences without distant metastasis. This report describes two cases seen after gynecologic operations for unrelated conditions, and details the usefulness of fine-needle aspiration (FNA) cytology in the management of MPIC. FNA in both cases yielded specimens which consisted of a monomorphorous population of mesothelial cells lacking cytologic atypia which were arranged as single cells. The background was clean with neither necrotic debris nor abundant inflammatory cells. The mesothelial cells were not arranged in prominent papillary formations; no mitotic figures were found. Both cases were treated successfully, laparoscopically or with hormonal therapy after FNA cytology, which facilitated determination of the characteristics findings of MIPC.
