Adult granulosa cell tumor of left ovary of 92 year old Mexican American woman. CT scan. 18 x 12 x 20 cm multi-loculated multi-septated cystic mass fills the entire urinary pelvis and extending up to the lower abdomen. A. A diffuse pattern appears at low power. B. Pale, round to ovoid nuclei lack mitoses, have little discernible cytoplasm, and are haphazardly arranged. Nuclear grooves, two with arrows, are readily identified. Nucleoli are small. Necrosis was not seen. C. Occasional tubules, indistinguishable from those seen in well-differentiated Sertoli cell tumors, are not considered reason to doubt a diagnosis of granulosa cell tumor if they account for less than 10% of the tumor; these were the sole such tubules in this specimen. D. Call-Exner bodies often bear degenerating nuclei. | |||
