Teratoma is derived from a primordial germ cell and is the most common germ cell tumor (GCT) in young women.1 the patients diagnosed with mature teratoma are commonly in their childbearing years, 13–76, with a median age of 30.2 Still, mature teratoma also can be found in males with germ cell neoplasm or testicular cancer, even tho this is quite rare. In most cases, various well-differentiated tissues from one or more of three embryonic germ layers can be found in the neoplasm of mature teratoma, like hair, teeth, bone, skin, fat and sebaceous glands. According to previous reports, the incidence of malignant conversion of mature teratoma is 1–2%, especially in older women, although most are benign.3
Most teratoma arise from the ovaries, but they can also occur in some extragonadal organs. reports of teratoma occurring primarily in the bladder are extremely rare.2
Here,we report on a case of a female patient who suffered primary bladder teratoma.She visited the hospital as she kept finding stones in her urine and was diagnosed by cystoscopy and histological confirmation. We also conducted a literature review concerning primary bladder teratoma.
Case Report
A 53-year-old post-menopausal Chinese woman presented with a chief complaint of repeated urinary interruption over a period of 5 years. There was neither a meaningful personal history nor any family history of malignancy, and she denied having any significant medical history or occupational exposure. According to her recollection, she had a history of pilimiction (hairs in the urine) in 1996 but did not get medical help because there was no reoccurrence thereafter. From June 2019 onwards, she occasionally found some little flaky stones in her urine. She did not attend the hospital until the frequent experience of urinary interruption in February 2024. She was diagnosed with a bladder stone after receiving abdominal computed tomography (CT) scan (Figure 1A) and ultrasound examination (Figure 1B). An operation was recommended but she rejected this option and ultrasonic lithotripsy treatment instead. After that, she intermittently found some circular stones with hair (Figure 1C) in her urine; meanwhile, urinary interruption still occurred occasionally.
In July 2024, she attended our hospital for treatment. No remarkable findings were seen on physical examination and a urine test showed: a white blood cell count of 3+, a urinary occult blood count of 3+, and nitrite (NIT) count of 2+. Urine culture was positive for Escherichia coli. Other laboratory tests, a chest X-ray and an electrocardiogram found no obvious abnormalities. We planned a cystoscopy after 3 days of antibiotic therapy. Cystoscopy showed a 2cm×4 cm white, pedunculated neoplasia with hair on the top wall of the bladder as well as
Rare Case of Bladder Teratoma in a 53-Year-Old Woman: A detailed Report
In a rare medical case, a 53-year-old woman was diagnosed with a bladder teratoma, a type of tumor that typically contains tissues like hair, teeth, or even glandular structures. This unusual condition, which primarily occurs in the bladder, was successfully treated through surgical intervention. The case, documented in a recent study, provides valuable insights into the diagnosis and management of this rare neoplasm.
the Case: A Unique Presentation
The patient presented with a neoplasia in the bladder, which had a stone attached to its surface. The stone was covered with hair, giving it a peculiar appearance that resembled a “needle mushroom” or “crab leg” (file/497270/aW1n/RRUA497270OF0002g.jpg”>Figure 2C and D).
histopathological examination revealed that the tumor was a mature teratoma,confined to the bladder wall. The slide showed distinct tissue types, including hair follicles, sebaceous glands, fibrous tissue, glandular tissue, adipose tissue, nervous tissue, and ganglion cells (Literature Review and Clinical Insights
The study also included a literature review of nine reported cases of bladder teratoma, focusing on clinical data published in English between 2000 and 2024. The review highlighted the rarity of this condition and provided a comparative analysis of diagnostic and treatment approaches (Key Takeaways

Table 1 Summary of Clinical Data of Reported Bladder Teratoma Cases in Recent Years
CT scan and cystoscopy are the best means of diagnosis, especially cystoscopy because it can efficiently differentiate tumors from recurrent stones or urinary tract infection.
Given this particular combination of a rare occurrence and a classic symptom, we hereby present this case to remind clinicians to consider this rare tumor in the bladder with various symptoms and help them make diagnostic and therapeutic decisions.
Conclusion
Teratoma in the bladder is usually rare but should be considered when encountering a patient with recurrent bladder stones or urinary tract infections. cystoscopy can be employed as a diagnostic approach and total tumor excision usually suffices. Here, we reported on a 53-year-old woman with chief complaints of urinary interruption, pilimiction, and stones in her urine. She was diagnosed with bladder teratoma and rehabilitated after tumor resection surgery.

Bladder teratomas, though exceedingly rare, have been the subject of increasing medical interest due to their unique presentation and diagnostic challenges. These tumors, which are typically benign, arise from germ cells and can contain a variety of tissue types, including hair, teeth, and even bone. Recent case reports and literature reviews shed light on this unusual condition,offering insights into its diagnosis,treatment,and clinical importance.
understanding Bladder Teratomas
A mature teratoma of the bladder is a rare entity, with only a handful of cases documented in medical literature. These tumors are often discovered incidentally during imaging or while investigating symptoms such as hematuria (blood in urine) or urinary obstruction. According to a case report by Prihadi and Kusumajaya, these teratomas are more commonly found in adolescents, though they can occur at any age.The diagnosis of bladder teratomas can be challenging due to their rarity and the nonspecific nature of their symptoms. Imaging techniques such as ultrasound, CT scans, and MRI are crucial in identifying these tumors. however, as Shah et al.note in their study, the definitive diagnosis often requires histopathological examination following surgical removal.
Case Studies and clinical Insights
one notable case involved a mature cystic teratoma in a young patient, as reported by Shah et al.The tumor was successfully excised, and the patient recovered without complications. Similarly,agrawal et al. documented a case of a primary bladder dermoid, another rare variant of teratoma, which was managed through surgical intervention.
In another instance, Okeke et al.described a dermoid cyst of the urinary bladder that was initially mistaken for a bladder calculus. This highlights the importance of considering teratomas in the differential diagnosis of bladder masses, especially in cases where imaging findings are ambiguous.
Treatment and prognosis
The primary treatment for bladder teratomas is surgical excision. As Jain et al. emphasize in their report, complete removal of the tumor is essential to prevent recurrence. Fortunately, most bladder teratomas are benign, and patients typically have an excellent prognosis following surgery.
Key Takeaways
| Aspect | Details |
|————————–|—————————————————————————–|
| Prevalence | Extremely rare, with few documented cases globally |
| Common Symptoms | Hematuria, urinary obstruction, incidental findings on imaging |
| Diagnostic Tools | Ultrasound, CT, MRI, histopathological examination |
| Treatment | surgical excision |
| Prognosis | Excellent, with low recurrence rates for benign teratomas |
Why This Matters
Bladder teratomas, though rare, underscore the importance of thorough diagnostic evaluation in urological practice. As Jain SK et al. point out, these tumors can mimic other bladder conditions, making accurate diagnosis critical for effective treatment.
