Mesanenin Nadir Benign Neoplazmı: Mesane Leiomyomu

Mesanenin benign mezenşimal lezyonları oldukça nadirdir ve tüm mesane tümörlerinin %1-5’inin oluştururlar. Bunların içinde de en sık leiomyoma saptanmaktadır. Benign lezyonlar radyolojik olarak maling kitleleri taklit etmesi nedeniyle klinik öneme sahiptir. Tanı radyolojik tetkiklerle kitlenin saptanması ve sonrasında yapılan cerrahi eksizyon ya da biyopsi ile histopatolojik olarak konulmaktadır. Ekstravezikal ve intramural form sistoskopik olarak saptanamayabilirken intravezikal leiomyomlar sistoskopi ile saptanabilir. Sistoskopi sırasında mesane içinde protrüde, kısmen düzgün sınırlı ve yüzeyi mesane mukozası ile kaplı lezyonlar görüldüğünde mesane leiomyomu ayırıcı tanıda düşünülmelidir. 44 yaşında kliniğimize irridatif semptomlarla tarafımıza başvuran ve mikroskopik hematüri saptanan erkek hastada mesanede 2x2 cm kitle saptandı. Minimal invaziv tedavi (TUR-mesane) sonrasında leiomyoma tanısı konulan vaka sunulmaktadır.

Rare Benign Neoplasm of the Bladder: Leiomyoma of the Bladder

Benign mesenchymal lesions of the bladder are very rare and constitute 1-5% of all bladder tumors. Among these, leiomyoma is the most common. Benign lesions are clinically important because they mimic radiologically malign masses. The diagnosis is made histopathologically by detecting the mass by radiological examinations and subsequent surgical excision or biopsy. Extravesical and intramural forms may not be detected cystoscopically, while intravesical leiomyomas can be detected by cystoscopy. Bladder leiomyoma should be considered in the differential diagnosis when protruding, partially smoothly bound and covered bladder mucosa lesions are observed during cystoscopy. A 44-year-old male patient who presented to our clinic with irridative symptoms and was found to have microscopic hematuria and 2x2 cm mass in the bladder. A case of leiomyoma diagnosed after minimally invasive treatment (TUR-bladder) is presented.
