Email: fakhirbouchra@hotmail.com  Received for publication on 25 December 2008. Accepted in revised form 13 January 2009     Key words: Cyst; Epidermic; Pelvis.  To The Editor: Epidermoid cyst is a frequent benign cutaneous tumor that could occur  in any part of the human body. The pelvic cysts are uncommon and only a few cases are described in the literature. The following is a report of a rare case of a pelvic epidermoid cyst.   A seventy year old multiparus lady presented with progressive swelling in the abdomen. Clinical examination confirmed a large mass in the abdomin. The ultrasound showed a giant 35 cm abdomino-pelvic echogene mass, extending from the pubis symphysis to the epigastric region, displacing the liver, spleen and the urinary bladder. The computed      tomography showed similar finding (figure 1). A giant ovarian cyst was diagnosed.  Median laparotomy was performed and a 30 cm retroperitoneal cyst was found. Ovaries and uterus were normal. Uneventful cyst cleavage was performed after liberation of some intestinal and epiploic adherences (figure 2). The cyst contained sebaceous matter and histological examination shows that the cystic wall was lined with flattened squamous epithelia with a distinguished granular layer. The cystic space was filled with a large amount of keratinized material. The histology was compatible with an epidermoid cyst. The post operative course was uneventful and the patient was doing well at the 5 months follow-up visit.      Figure 1: Reconstruction of the image with CT scan, giant intra-abdominal mass.

In children it is associated with a Gardner syndrome in 50% of cases [1]. It was described in various parts of the body including penis, spleen and brain [2-4]. It is the most frequent cutaneous cyst in the head and neck (49%) [5]. Only three cases of pelvic epidermoid cyst were reported in the literature, one was retroperitoneal [1] and the other two were retro-rectal [6,7]. Concerning pathogenic theories, the epidermal cyst could be congenital, or post traumatic [8]. Epidermoid cysts are benign tumors with no risk of malignant transformation, but they may grow insidiously to reach a considerable sizes displacing or damaging other tissues and organs [9].   Pre-operatively, diagnosis of pelvic epidermoid cyst is difficult. Ultrasound and computed tomography often lead to a diagnosis of ovarian cyst. Magnetic resonance imaging (MRI) is more specific, as it shows epidermoid cyst as hypointense area on T1-weighted imaging and hyperintense on T2 weighted imaging without enhancement at contrast injection [10]. MRI could also help in confirming retroperitoneal localization; unfortunately it was not performed in our patient’s case.   The treatment of the pelvic epidermoid cyst is a surgical ablation using a cleavage to avoid any organ damage. However, in dealing with retroperitoneal space it could be difficult to avoid damaging iliac vessels and nerves [11] and if that is the case then the cyst must be punctured and drained before it  is dissected. Precaution should be taken to avoid spillage of the contents out. A successful laparoscopic excision of a retro-rectal epidermoid cyst was described [7].   In conclusion, this report described a patient with a giant retroperitoneal pelvic epidermoid cyst which was successfully treated surgically. Although the pelvic epidermoid cysts are rare and difficult to diagnose pre-operatively, it should be considered in the differential diagnosis of ovarian tumors.
