Vesical dermoid: a rare bladder tumour

Abstract

Dermoid cysts are benign developmental lesions consisting of tissues of more than one germ cell lineage origin. The urinary bladder is a very rare location of dermoid cysts. We report a case of an 18-year-old woman who presented with suprapubic pain, dysuria and turbid urine. Blood and serum chemistry was normal. Contrast-enhanced CT revealed a heterogeneously enhancing mass of 2.5×2 cm within the urinary bladder infiltrating fundus of urinary bladder with extraluminal extension. At cystoscopy, an irregular mass arising from the dome of the urinary bladder with a covering of hair and whitish scales was seen. The patient was managed by transperitoneal laparoscopic partial cystectomy with left oophorectomy. Histology revealed dermoid cyst arising from the urinary bladder and simple serous cyst in the ovary. Postoperative course was uneventful.

Numerical Analysis of the Heat and Fluids Flow Performance of Cuo-nanofluids in Flat Tube with Bend

“…Maximum decrease of 14.97 % is obtained at 0.3 % volume concentration upon use of bent tube. (6). Friction factor increases with rise in nanoparticle concentrations and decreases with rise in Reynolds number.…”

“…Almost every study conducted after introduction of nanofluids terminology have reported significant amount of enhancement in performance of conventional heat transfer fluids [3][4][5][6][7][8]. Heris et al [9] reported in their study of Al2O3/water nanofluids flowing through circular tube that heat transfer coefficient increased with increase in volume concentration of nanoparticle from 0.2 % to 2.5 % with Reynolds number varying in between 700 and 2050.…”
