Summary
Bladder leiomyoma, a rare benign tumor, can present atypically. Accurate diagnosis is crucial to differentiate it from bladder cancer and ensure proper patient management.
Area of Science:
- Urology
- Pathology
- Oncology
Background:
- Bladder leiomyoma is a rare, benign mesenchymal tumor, predominantly affecting women.
- Typical symptoms include urinary frequency and obstructive voiding issues.
Observation:
- A 50-year-old woman presented with abdominal pain and vaginal bleeding, atypical symptoms for bladder leiomyoma.
- Imaging revealed a posterior urinary bladder mass.
Findings:
- Surgical pathology confirmed a benign mesenchymal neoplasm with smooth muscle fibers, consistent with bladder leiomyoma.
- The tumor exhibited interlacing bundles and a whirling pattern.
Implications:
- Bladder leiomyoma can be misdiagnosed as urothelial lesions or carcinoma.
- Prompt and accurate diagnosis is essential for appropriate clinical management and treatment.
- Distinguishing benign leiomyoma from malignant urothelial tumors is critical.

2.0K
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs...

01:19Histology of the Uterus
1.9K
The uterine wall consists of three histological layers: the perimetrium, myometrium, and endometrium. The outermost perimetrium is a thin, serous membrane connected with the broad ligament on the sides, which helps anchor the uterus in the pelvic cavity. The thickest layer, myometrium, is mainly made up of smooth muscle tissue bundles. Its contractions are vital in facilitating the expulsion of the uterine lining, fetus, and placenta during menstruation and childbirth.

01:16Uterine Tubes
969
The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:22Ureters
703
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
