The value of 'raspberry bodies' in intraoperative cytologic evaluation of adnexal masses for the diagnosis of clear cell carcinoma of the ovary: A cytological-pathological correlation.

We report a case of a 48-year-old female who presented to the emergency department with pelvic/abdominal pain and a recent history of irregular periods. Pelvic ultrasound and computed tomography (CT) scan of the abdomen/pelvis revealed a 7.3 cm adnexal mass with suspicious features. During the intraoperative evaluation, a frozen section slide and a cytological smear were prepared. The cytological preparation was moderately cellular, showing cohesive groups of atypical cells with anisonucleosis, high nuclear to cytoplasmic ratio, and oval nuclei with prominent nucleoli. The tumor cells surrounded extracellular, magenta hyaline globules, forming raspberry bodies. Raspberry bodies are comprised of basement membrane deposits and are a unique finding in ovarian clear cell carcinoma. Raspberry bodies were also found in the frozen section slide, but, in comparison to the cytological preparation, were rare, difficult to identify, and resembled necrotic debris. The intraoperative diagnosis of a clear cell carcinoma is important because the surgical management will be more aggressive, as optimal tumor debulking is shown to have better overall survival. In this manuscript, we detail the intraoperative evaluation of an ovarian mass, the utility of cytological preparation and importance of identifying raspberry bodies in the evaluation of ovarian masses, and surgical management of clear cell carcinoma.
