Bladder leiomyoma is a rare benign tumor that can be found in different bladder parts. Leiomyomas can be investigated through a computed tomography (CT) scan or magnetic resonance imaging (MRI), along with cystoscopy, and surgical intervention is considered the standard treatment for this type of cancer. Our case is a 36-year-old female who presented to a urology clinic with lower abdominal pain and lower urinary tract symptoms (LUTS) for three months. The patient was investigated using MRI and was found to have intramural bladder leiomyoma, which was treated with partial cystectomy with bladder mass resection as it is the gold standard treatment.

Urachal adenocarcinoma (UA) represents a rare subset of bladder tumors involving a urachal remnant. Incidental gross hematuria is often the only presenting symptom, with patients often presenting late in their course, thereby imparting an overall poor prognosis. Although there are prior case reports, there is little literature reported and no standardized treatment guidelines. We report a case of a middle-aged male who presented with incidental gross hematuria after a fall. Workup indicated the presence of a calcified bladder dome mass and pathology reported a primary urachal adenocarcinoma with pelvic nodal involvement. Patient underwent surgical resection and subsequent adjuvant, systemic chemotherapy regimen with leucovorin, fluorouracil, and oxaliplatin (FOLFOX). We hope to bring greater awareness to this rare cause of bladder malignancy.

This case details a 69-year-old female with a 3cm bladder mass on imaging who underwent transurethral resection of the bladder with pathology revealing non-Hodgkin follicular lymphoma to the bladder. The rarity and complexity of this presentation generated a challenging treatment dilemma regarding surveillance and active treatment.

Sarcoidosis is a multi-organ systemic disease that presents with several clinical manifestations, and patients can develop neurologic complications. Neurosarcoidosis may be life-threatening; therefore, early recognition and treatment are key. Here, we present a case of a 55-year-old African American male who presented with a complaint of dizziness and left-sided weakness; he ultimately received a diagnosis of neurosarcoidosis after elaborate radiographic investigations and bladder mass biopsy. Neurosarcoidosis remains a diagnostic dilemma as it can clinically and radiographically mimic multiple conditions including multiple sclerosis, central nervous system lymphoma, multiple myeloma, and progressive multifocal leukoencephalopathy.

Lymphoepithelioma-like carcinoma (LELC) was characterized by epithelial neoplastic cells developing in solid or incohesive sheets mixed with a noticeable lymphoid infiltration. Lymphoepithelioma-like carcinoma of the bladder (LELCB), which was first described by Zukerberg, is a rare variant of LELC. Here we reported a new case of LELCB occurring in a 70-year-old woman presenting with hematuria. Computed tomography (CT) and cystoscopy revealed a tumor on the left upper wall of the bladder. A partial cystectomy was finally performed. Pathological and immunohistochemical analysis revealed LELCB. After receiving systemic adjuvant chemotherapy, the patient conducted a 25-month follow-up without experiencing a recurrence.

UNASSIGNED: One of the few remaining important issues in urological and gynaecological surgery relates to fistulas between the urinary tract and the vagina. Vesicovaginal fistula (VVF) and ureterovaginal fistulas (UVF) are defined as abnormal connections between the urinary tract, on the one side, and the female genital system, on the other.
UNASSIGNED: This study is about an unreported and undescribed case of 24 year old female who presented with the complaints of continuous urinary incontinence for 18 months following total abdominal hysterectomy. Preoperative cystoscopy and vaginal/speculum findings revealed a papillary frond like mass protruding intravesically from VVF site which was free from the edges of fistulous opening all around. Also, left ureteric orifice was not visualized. On exploration, there was evidence of intravesical herniation of right tubal fimbria through the common opening of VVF and left UVF near left vaginal vault apex mimicking a bladder mass presenting with continuous incontinence for 18 months. Modified O\' Conners VVF repair with left ureteric reimplantation was done. The postoperative period was uneventful with patient having no incontinence.
UNASSIGNED: It seems that surgical resection of ovarian cyst with VVF and UVF repair is the definitive treatment and histopathological examination is essential to exclude malignant transformation.

Myoepithelial carcinoma is a neoplasm that classically arises in the parotid glands, nasopharynx, paranasal sinus, and nasal cavity of the head and neck. It rarely arises in other organs or soft tissues and involvement of genitourinary organs is distinctly rare. We describe a case of a 21-year-old male, presenting with nausea, weight loss, and worsening suprapubic pain over 3 months, found to have a large mass at the dome of the bladder. Partial cystectomy was ultimately performed revealing myoepithelial carcinoma of the bladder. The patient is free of disease at four years without the need for systemic therapy.

Inflammatory myofibroblastic tumours (IMTs) are rare neoplasms of uncertain malignant potential that closely resemble other more aggressive spindle cell tumours. The distinction of IMT from the latter is of importance. We report a case of IMT in a 27-year-old man who presented with intermittent painless, macroscopic haematuria and was found to have a large bladder mass arising from the dome of the bladder. The tumour was resected transurethrally, and histology and immunohistochemistry were consistent with an IMT of the bladder. Our patient remained asymptomatic at follow-up 3 months later, when cystoscopy noted no regrowth of the residual tumour. Transurethral resection resection of bladder tumour, partial cystectomy and radical cystectomy form the mainstay of treatment of IMT. However, the optimal management of this condition remains uncertain due to the sparsity of reported cases.

UNASSIGNED: Eosinophilic cystitis (EC) is a rare inflammatory urinary bladder disorder whose etiology, pathogenesis, and treatment are unknown. The work aims to evaluate the clinical manifestations, cystoscopic characteristics, pathological features, treatment, and clinical outcome of EC patients.
UNASSIGNED: The clinical records and histopathology material of 22 patients diagnosed as EC during ten years were reviewed and analyzed for patient\'s age, sex, clinical data, cystoscopic features, biopsy procedures, treatment plan, follow-up, and prognosis. Frequencies, normality tests, descriptive statistics, and correlations were run.
UNASSIGNED: The mean age of patients was 46.5 + 17 years, 12 females and 10 males. Regarding the patient\'s complaints, dysuria was the most frequent main symptom, followed by hematuria. On cystoscopic examination, bladder mass was seen in 54.5% of patients. Six patients (27.3%) were associated with different allergic diseases; however peripheral eosinophilia was shown in two patients (9.1%). All cases revealed predominance of eosinophilic infiltration on microscopic examination. The most commonly used medications were corticosteroids for 72.7% of patients with tapering dose giving a significant improvement with a recorded recurrence in one patient after 12 months from the first lesion.
UNASSIGNED: No specific clinical presentation for EC patients and histopathology is the standard diagnostic tool. Medical treatment including corticosteroids was the first line with good prognosis, although recurrence remains a possibility which emphasizes the importance of patients\' follow-up.

Surgical procedures that maintain continence with minimal complication following resection of trigono-urethral urothelial carcinoma (UC) are limited in canines; therefore, palliative options are often pursued. A feasible tumor resection option may improve disease control and survival. The study\'s objective was to evaluate a continent urine reservoir created from the urinary bladder body and vascularized solely by omentum. We hypothesized that a viable urine reservoir could be created, and staged omentalization would provide improved vascularity. Nine normal female Beagles were randomized to one of three groups. Group A urinary bladders were transected cranial to the ureteral papillae to create a closed bladder vesicle which was concomitantly omentalized. Group B underwent omentalization two weeks prior to vesicle creation. Based on Group A and B results, Group C underwent neoureterocystostomy and omentalization followed by neoreservoir formation and tube cystostomy 2 weeks later. Serial ultrasounds and histopathology confirmed adequate omental neovascularization in Groups B and C with continent Group C neoreservoirs maintained for 2 months. Some pylectasia and ureteral dilation was documented in all Group C dogs at variable timepoints. Progressive hydroureteronephrosis developed in 2/6 kidneys. Transient azotemia was noted in only 1 Group C dog, although all developed treatable urinary tract infections. The sample size is limited, and the efficacy of this technique in providing disease control for UC is unknown. However, this novel option could allow for primary UC resection while providing continence and limiting complications. Postoperative local or systemic adjuvant therapy, ultrasonographic neoreservoir monitoring, and BRAF analysis would be indicated.
