Hamartoma of the urinary bladder

Abstract

Background: Hamartomas of the urinary bladder are extremely rare. We report on a case in a 58-year-old female who presented with the chief complaint of pain on urination. Methods/Results: Cystoscopy revealed a solid tumor on the left posterior wall of the bladder. Transurethral resection of the tumor failed to provide a definitive pathological diagnosis of the tumor. Thus, we performed partial cystectomy. The pathological diagnosis was hamartoma arising from the urinary bladder. Conclusion: This is the ninth case diagnosed as urinary bladder hamartoma to be reported in the literature.

Hamartoma of the urinary bladder in a 15-year-old boy

“…Hamartomas have been often reported in the gastrointestinal tract, bronchial tree, brain and bone, but they are very rare in the urinary bladder. [1] Since the first reported case in 1949, [2] to our best of knowledge, only 11 cases have been reported in the literature so far. [3] Most of the patients had similar clinical presentations, with gross hematuria, dysuria, and mild suprapubic discomfort.…”

“…[3] Most of the patients had similar clinical presentations, with gross hematuria, dysuria, and mild suprapubic discomfort. [1,4] The size of the lesions may range from tiny growths to large masses. They are always solitary and may be located anywhere, although they favor the bladder dome or its posterolateral walls.…”

High-grade urothelial bladder cancer in children: A case report and critical analysis of the literature

“…Microscopically, the glands are dilated and may be filled with eosinophilic or proteinaceous secretions. Other pathological findings include a higher vessel density and a lack of cellular atypia or mitotic activity 13 . These are crucial differences in comparison with a typical urothelial bladder malignancy.…”

High-Grade Non-Invasive Transitional Cell Carcinoma with Osseous Metaplasia of the 3-Year-Old Boy Urinary Bladder

“…There are neither cellular atypia nor mitotic activity of the epithelial or mesenchymal component of the tumor suggestive of true neoplastic growth. Hematopyuria associated with infection or inflammatory reaction in the bladder is a characteristic clinical sign in most reported cases [11].
