“…Scattered dotted or pinpoint enhancing vessels can be observed inside the lesion. [15] It can be difficult to differentiate from mild SFT, but it is different from the typical bladder SFT. ④ Metastases may present as polyp-like or nodular lesions and, can be easily differentiated from bladder SFT based on medical history and clinical symptoms.…”

Rationale: Solitary fibrous tumors (SFT) is a rare mesenchymal tumor originating from a CD34-positive dendritic mesenchymal cell, most of which is benign, the most common sites is pleura and mediastinum, and rarely in the bladder. The clinical manifestations are mainly related to the tumor volume. When the tumor volume is large, it will compress the surrounding tissues or organs and cause corresponding symptoms. Laparoscopic Incision biopsy is effective means for diagnosing SFT. Patient concerns: A 70-year-old female patient was admitted to the hospital with a bladder neoplasm detected by computed tomography scan after experiencing intestinal obstruction 3 days following esophageal cancer surgery. She denied any history of tumor disease. Diagnoses: No abnormality was found in the physical examination and laboratory testing after admission. Ultrasound imaging showed a large solid mass with low echogenicity in the bladder. Urological computed tomography with 3D reconstruction revealed a large cystic-solid mass located on the right wall of the bladder, measuring approximately 6.8 cm × 7.1 cm × 6.5 cm, with uneven density and mild inhomogeneous enhancement after contrast administration. Cystoscopy revealed a large mucosal bulge on the right wall of the bladder and laparoscopic exploration revealed a smooth-surfaced round mass, approximately 7 cm in size. Interventions: Incision biopsy was performed to make a clear diagnosis, and appropriate tissue specimens were obtained for pathological testing. Outcomes: The patient was diagnosed as SFT according to pathology. The patient was followed up for 6 months after surgery, and no recurrence was observed. Lessons: SFT occurring in the bladder are extremely rare, and the site is scarcely reported in the relevant literature; thus, it is easy to misdiagnose and laparoscopic incision biopsy may be a good choice.

Bladder schwannoma is a rare tumour arising from Schwann cells in nerve sheaths. It is usually more common in patients diagnosed with neurofibromatosis. However, isolated cases of urinary bladder schwannoma is incredibly rare, attributing to <0.1% of bladder tumours. A literature review and analysis revealed that it presents in adulthood, is mostly symptomatic and diagnosis is established histologically. We report a case of isolated bladder schwannoma in 25 year-old female who presented with dyspareunia.
