Vesical dermoid: a rare bladder tumour

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 2.5x2 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.
