Discussion
In the hysterectomy specimen a diagnosis of confluent
stromomyosis was made
based on the low cellularity of the tumor, the bland
cytological features and
the absence of overt mitotic activity. The diagnosis
was supported by an
authorative expert in the field.
The recurrent tumor had to be classified as low-grade
stromal sarcoma. It was
more cellular, showed a higher proliferation rate and
lymphatic and venous
invasion. Retrospectively, vessel invasion was
also a finding in the
hysterectomy specimen.
