Epitheliod Leiomyoma of the Bladder: An Unusual Case of Irritative and Obstructive Voiding Symptoms

Bladder leiomyoma is a rare benign mesothelial tumor that is more commonly reported in women. Most patients present with frequent urination or obstructive urinary symptoms. Here, we portray a 50-year-old woman who presented to the clinic with abdominal pain and vaginal bleeding. Imaging showed a lobulated mass at the posterior aspect of the urinary bladder. The pathology of the surgery demonstrated a benign mesenchymal neoplasm composed of interlacing bundles of smooth muscle fibers with a whirling pattern, which eventually confirmed bladder leiomyoma. Although this tumor is benign, it can be misdiagnosed with other diseases such as a urothelial lesion or urothelial cell carcinoma of the bladder. Accordingly, it can inevitably affect patient management. Therefore, it must be diagnosed quickly and accurately and appropriate treatment should be applied.

“…The 2 different types of mass arise with a recurrence of 30% and 7% for extravesical and intramural, respectively. 16 Treatments can vary depending on the location and size of the tumor. Therapeutic options for bladder leiomyoma include TURBT, open surgery, and conservative.…”

“…Even if it represents less than 1% of bladder tumours, it is the most common benign soft tissue tumour of the bladder. Its presentation is most commonly with irritative symptoms, obstructive symptoms (3), dyspareunia, recurrent urinary tract infections (4) or haematuria (5). Intramural leiomyomas are less symptomatic and are usually discovered incidentally.…”

Introduction Bladder leiomyomas (LM) are uncommon, non-cancerous growths that originate from the smooth muscle cells of the bladder and constitute 0.5% of bladder tumor cases. This review aims to compile existing data and present a summary of bladder leiomyomas’ characteristics, management, and related outcomes. Method We conducted systematic review of studies that investigated bladder leiomyoma. Case studies or series describing individuals with bladder leiomyoma who underwent surgery and the outcomes were included. Four databases were used in our literature search, which was carried out until January 2024: PubMed, Proquest, EBSCOHost, and Google Scholar. We utilized MeSH terms such as “leiomyoma,” “urinary bladder,” and looked for synonyms of “bladder leiomyoma” in free text. Results A total of 99 studies with 119 patients were included. Most reported bladder leiomyoma cases were female, accounting for 79.0% of all cases. While symptomatic patients primarily presented with lower urinary tract symptoms (LUTS) (59.7%), hematuria (24.4%), acute urine retention (11.8%), and about 16.8% of cases were incidentally detected. Storage-related symptoms were the most common LUTS (37.0%). Different diagnostic techniques were used, frequently combining CT (Computed Tomography), MRI (Magnetic Resonance Imaging), USG (Ultrasonography), and/or cystoscopy. Bladder leiomyomas were commonly found on the left lateral wall (26.9%) and the bladder neck (17.6%). In more than half of the cases (52.1%) the treatment techniques used were transurethral resection (TURBt/TUR). Fifteen out of 119 cases (12.6%) had recurrence or remain symptomatic. Symptomatic symptoms at first presentation and extended location are frequently found among recurrent or symptomatic cases after first management. Conclusion Management of bladder leiomyoma should focus on the relief of symptoms and recurrence and be personalized based on the tumor characteristics, patient symptoms, and surgeon’s expertise. Further investigation is necessary to fully understand the best course of treatment and long-term results for bladder leiomyomas. In particular, prospective trials with bigger participant pools and meticulously controlled factors should be the main emphasis of this research.
