Abstract

Uterine leiomyomas are common uterine tumors, and typical cases of leiomyoma are easily diagnosed by imaging study. However, uterine leiomyomas are often altered by degenerative changes, which can cause difficulty and confusion in their clinical diagnosis. We describe the 17th reported case of a uterine leiomyoma clinically diagnosed as an ovarian tumor; however, the present case shows the most detailed radiological evaluation, including contrast-enhanced magnetic resonance imaging. We first show that a uterine leiomyoma can histologically mimic an adenomatoid tumor. A 47-year-old premenopausal, nulliparous Japanese woman with a history of type 2 diabetes mellitus, hypertension, and hyperlipidemia had lower abdominal pain. Ultrasonography confirmed a 6-cm mass in the right-sided space of the pelvic cavity. Magnetic resonance imaging evaluation showed that a multilocular mass was present near the uterus, and a mucinous ovarian tumor was considered. Emergency surgery due to acute abdomen was performed under the diagnosis of pedicle torsion of the ovarian tumor. During surgery, a pedunculated uterine mass without stalk torsion was seen. The mass grossly contained serous and hemorrhagic fluids in the cavities, and pathology examination confirmed that the mass was a leiomyoma with hydropic and cystic degeneration. Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. The tumor cells were positive for the microphthalmia transcription factor but negative for other melanoma markers. Three days postoperatively, she was discharged without sequelae. Marked intratumoral deposition of fluids may induce the multilocular morphology of a tumor, and the cellular arrangement of the tumor cells with hydropic degeneration mimicked an adenomatoid tumor in this case. Clinicians need to be aware that a subserosal leiomyoma with cystic and hydropic degeneration can mimic an ovarian tumor, and pathologists should be aware that such leiomyomas can mimic adenomatoid tumors. Additionally, perivascular epithelioid cell tumors should not be diagnosed only based on its immunoreactivity for the microphthalmia transcription factor.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 March 2017.
All research outputs
#17,849,965
of 22,925,760 outputs
Outputs from Journal of Medical Case Reports
#1,917
of 3,935 outputs
Outputs of similar age
#293,618
of 420,907 outputs
Outputs of similar age from Journal of Medical Case Reports
#34
of 89 outputs
Altmetric has tracked 22,925,760 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,935 research outputs from this source. They receive a mean Attention Score of 3.9. This one is in the 42nd percentile – i.e., 42% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 420,907 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 89 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
