Adult granulosa cell tumor of the ovary: fine-needle-aspiration cytology of 10 cases and review of literature
Abstract
Adult granulosa cell tumor (GCT) of the ovary is mostly diagnosed in postmenopausal women. They typically secrete estrogen, which stimulates the endometrium to proliferate and cause abnormal bleeding. This study reviews the cytologic features of adult GCT of the ovary diagnosed by fine-needle aspiration (FNA). We reviewed slides from ten cases diagnosed by CT guided FNA from 1995 to 2007 at our institutions. Smears were stained with Diff-Quik and Papanicolaou stains. Patient's history and histologic diagnosis were also available and reviewed for all cases. The patients ranged in age from 39 to 83 yr. All 10 cases were hypercellular with both large and small overlapping cell clusters and individual cells. The cytologic features identified included: naked nuclei (10/10 cases), Call-Exner bodies (7/10 cases), blood vessels with prominent perivascular tumor cell growth (4/10 cases), spindle-shaped hyperchromatic stromal cells within cellular clusters (6/10 cases), mixed inflammation (3/10 cases), tumor cell necrosis (1/10 cases), and prominent metachromatic stroma seen in association with blood vessels (1/10 cases). Moderate to scant delicate cytoplasm was also seen (10/10 cases). Small, punctuate cytoplasmic vacuoles were also not...Continue Reading
