 Introduction | |  |
Dermoid originates commonly in the testis, ovary, retroperitoneal and sacrococcygeal areas. [1] A defect in differentiation of embryonic cells or blastogenic theory explains the formation of dermoids in the above areas. This report presents two cases of ovarian dermoids perforating silently into the urinary bladder and presenting with urinary complaints.
| Case Report 1 | | |
A 31-year-old female presented with history of recurrent episodes of dysuria and pyuria of six-months' duration. She underwent ultrasound and intravenous urogram, which was suggestive of bladder calculus. Cystoscopy showed a calcified mass with hair in the posterior wall. Transurethral resection was done and biopsy proved to be dermoid of the ovary. Patient was advised exploration, which she refused.
| Case Report 2 | | |
A 50-year-old female presented with history of recurrent episodes of dysuria and pyuria of one-year's duration. She underwent ultrasound and intravenous urogram, which was suggestive of calcification in the bladder [Figure - 1]. Cystoscopy showed a mass lesion in the dome of the bladder with teeth and tufts of hair. Partial cystectomy and left oophrectomy was done [Figure - 2]. Biopsy showed it to be dermoid from the ovary infiltrating bladder. There were no malignant elements.
| Discussion | | |
Though primary bladder dermoids are extremely rare it has been reported as early as 1700 by Wallace. [2] The common presentation is an ovarian dermoid eroding into the urinary bladder. This erosion being a slow process the patient will not have acute presenting complaints. Irritative voiding symptoms of a long duration is commonly present. Though symptoms like passage of hair is a definitive pointer to the diagnosis, in both of our cases it was absent. The final diagnosis was revealed only during cystoscopic evaluation when hair and teeth were noted. Partial cystectomy with removal of the affected ovary is the curative treatment.
