Angiomyxoma of the ureter imitating an upper tract urothelial carcinoma: A case report

Abstract

HighlightsAngiomyxomas are rare benign neoplasms tumors arising from the soft tissues of the perineum and pelvis.Although benign, they are notorious for their locally infiltrative nature and their propensity to recur.To the best of our knowledge, we report the first case of ureteral angiomyxoma in the literature presenting with hematuria.If an angiomyxoma were to be considered in our differential diagnosis, a ureteral biopsy could have led to an organ-sparing surgery.

Incidental para-ureteral aggressive angiomyxoma: a rare case report and literature review

“…While, for those extensively and deeply invading the surrounding vital organs, if complete excision is infeasible or severe surgical injuries may happen, incomplete resection combined with adjuvant therapy are recommended [ 10 ]. Zugail et al reported a 35-mm AA mimicking an upper tract urothelial carcinoma (UTUC) of the right pelvic ureter treated with nephroureterectomy [ 11 ]. In our case, the tumor was small and well-defined, so wide local excision was performed successfully.…”

Aggressive Angiomyxoma: A Rare Perineal Mass

“…On MRI, due to increased water content and loose matrix of these lesions, they appear hyperintense on T2-weighted imaging and masses demonstrate a 'swirled' pattern 3,9,10 . Gilardi et al reported modorate FDG uptake of an AAM with 3.75 SUV max 11 .…”

“…Female/male incidence ratio is 6:1 1 . Generally, this tumour is found in the pelvic and perineal region of female but there are cases with intrabdominal AAM located in liver and pelvic ureter 2,3 . Patients with perineal AAM usually present with a nontender, edematous lesion which is found as a reducible mass in physical examination 4,5,6 .…”
