An ultrasound showed the presence of a large mass, measuring 15.9 cm x12.0 cm x8.6 cm (longitudinal [A] and transverse [B]), with no definite evidence of local infiltration and lymphadenopathy, which was highly suspected as subserosal uterine leiomyoma.

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).
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.
