case_images: Subsequent abdominal and pelvic ultrasound revealed the presence of a 15.9 cm x12.0 cm x8.6 cm mass, with no definite evidence of local infiltration and lymphadenopathy, which was highly suspected as subserosal uterine leiomyoma (Figure 1).
case_images: HE staining of the specimen (x200) (A), and immunohistochemical examination revealed CD10 (+) (B), CD20 (+) (C), Bcl-6 (+) (D), and suggested putative germinal center B-cell origin.. Abbreviation: HE, hematoxylin.
