“…Umbilical discharge was only seen in the pediatric cases. Diagnosis of the urachal anomaly was made by US supplemented by a CT‐scan in three of the cases and in two cases, including the current one, also an MRI . Radiographic imaging revealed in the majority of cases a cystic mass in close correlation with the urachus.…”

Urachal anomalies are most often seen in children, seldom in adults, but are in general considered rare. The estimated incidence is one in 5000-7000 live births and appears twice as common in males. Despite their rarity, they need to be considered by clinicians, as diseases in the urachus can mimic many abdominal and pelvic conditions and constitute an important differential diagnosis to these. Diagnosis can be made by clinical examination and imaging modalities (computed tomography, ultrasonography, magnetic resonance imaging, voiding cystourethrogram), but some are discovered incidentally. Management of symptomatic urachal anomalies is surgery. Histological examination of the specimen should always be performed to rule out malignancy. We report on the first adolescent described in the literature diagnosed with a urachal sinus harboring a benign teratoma. A combination of the two pathologies is by inference an extremely rare condition, which we here report on and we review the relevant literature on this topic.

“…Both tumors were successfully removed and the patients rendered asymptomatic. Subsequently, three more cases of urachal teratomas have been reported in the literature, two in English (1998 and 2006) and another one in the French literature (2006) (Table ).…”

“…[4] Other benign tumors like desmoid tumor, inflammatory myofibroblastic tumor and teratoma arising from the urachus have also been reported. [67] Leiomyoma of the urachus is a rare entity with only seven cases being reported. [2] Its incidence is suspected to be higher, but this tumor type is detected only when complications such as bleeding or infection arise.…”

“…The radiological differential diagnosis also include adenocarcinoma of non-urachal origin, transitional cell carcinoma, infected urachal remnants and metastasis originating from primary lesions of colon, prostate or female genital tract. [47] Because of lack of specificity of CT and ultrasonography in the differential diagnosis of solid urachal masses, a definitive pathological diagnosis is required to optimize the surgical approach and preclude unnecessary radical surgery.

Angiomatous leiomyoma of the urachus: A rare entity masquerading as extraluminal gastrointestinal stromal tumor

et al. 2013

The urachus is a vestigial structure located between the dome of the bladder and the umbilicus, which results from the involution of the allantoic duct and the cloaca. Persistence of an embryonic urachal remnant can cause various problems during childhood and young adulthood. Urachal leiomyoma is a rare entity with very few cases being reported in literature. It can be misdiagnosed and confused with a wide spectrum of intra-abdominal or pelvic disorders. We hereby report a case of angiomatous leiomyoma originating from the urachal remnant in a 45-year-old lady, masquerading as extraluminal gastrointestinal stromal tumor. Understanding the embryological basis of these urachal disorders and their imaging features coupled with histopathological examination is crucial for the correct diagnosis and management. Pathological diagnosis is required to optimize the surgical approach and preclude unnecessary radical surgery.

“…Other malignant urachal lesions that have been described in the literature are endodermical sinus tumor [13], neuroblastoma [8], teratoma [14], and mixed tumors [3]. Therefore, in this location, the most commonly diagnosed tumors during early infancy should be considered in the differential diagnosis of the different urachal anomalies [1,4,5], the most frequent being the persistence of an embryonic urachal remnant.…”

RADICAL SURGERY AND IVA-CHEMOTHERAPEUTIC REGIMEN TO TREAT EMBRYONAL RHABDOMYOSARCOMA OF THE URACHUS: Case Report

Although rhabdomyosarcoma is the most frequent soft tissue tumor in children, there are extremely few reports of this tumor arising from the urachus. The authors describe another case in a 6-year-old female associated with constipation and a painless suprapubic mass. The specimen had the pathological criteria used to define urachal sarcoma (cytological, histological, and immunohistochemical findings) and urachal remnants were not observed. After complete resection of the primary tumor the patient was treated with chemotherapy (ifosfamide, vincristine, and dactinomycin) and remains alive at 4 years' follow-up with no signs of recurrence. Nowadays the management of children with urachal rhabdomyosarcoma usually includes surgery and chemotherapy. Multimodal therapy and surgery are constantly evolving and have significantly improved overall survival of these patients especially in R0 resected patients.
