Copyright © 2012. Korean Society of Obstetrics and Gynecology Due to its bizarre and atypical behavior, accurate diagnosis of a pelvic mass prior to exploration of the pelvic cavity by laparotomy or laparoscopy is a challenge to the gynecologist. Pelvic mass is one of the most common clinical presentations, representing a number of benign and malignant conditions. Beforehand knowledge of whethe...

Neurilemomas are benign usually encapsulated nerve sheath tumors derived from the Schwann cells. These tumors commonly arise from the cranial nerves as acoustic neurinomas but they are extremely rare in the pelvis and the retroperitoneal area (less than 0.5% of reported cases), unless they are combined with von Recklinghausen disease (type 1 neurofibromatosis). We report the case of a 58-year-o...

Urachal carcinoma is a rare neoplasm, which accounts for only 0.5-2% of bladder malignancies, and arises from a remnant of the fetal genitourinary tract. A 46-year-old woman presented with a history of pelvic pain and frequent daytime urination. Ultrasound (US), computed tomography (CT), and magnetic resonance (MR) demonstrated a supravesical heterogeneous mass with calcifications. The patient ...

Eccrine porocarcinoma is a rare neoplasm that originates from the intraepidermal ductal portion of the eccrine sweat gland, and it usually occurs on the pre-existing lesion of benign eccine poroma. Its occurrence is more common in females and elderly persons. We present a case of a 44-year-old man who suffered from eccrine porocarcinoma, which developed on the right scrotum and pelvic area with...

This report describes two patients who developed leiomyosarcomas, one involving the subcutaneous tissue of the thigh and the pelvic soft tissues and the other the urinary bladder, following hereditary retinoblastoma 36 and 38 years earlier, respectively. There is an increased risk of the development of sarcoma, most commonly osteosarcoma, as a second malignancy following hereditary retinoblasto...

The parasitic tapeworm Echinococcus granulosis causes hydatid disease, which is rarely encountered in nonendemic regions. It is a progressive disease with serious morbidity risks. Rarely, these cysts are found in the spine. They are mainly found epidurally, originating from direct extension from pulmonary, abdominal or pelvic infestation. Nevertheless, the main mechanism for intradural involvem...

Angiomyxoma is a rare, slow-growing myxoid neoplasm that occurs almost exclusively in the genital, perineal, and pelvic regions of adult women. It mostly occurs during the reproductive years. It has propensity for local recurrence [1–4]. Macroscopically, they are soft, partly circumscribed, polypoids; across cross section, they have a glistening, homogeneous, gelatinous appearance; and sizes ra...

Appendiceal tumors are rare, late diagnosed neoplasms that may not be differentiated from adnexal masses even by advanced imaging methods and other diagnostic procedures. They may be asymptomatic and remain undiagnosed until surgery. We report a case of an 80-year-old postmenopausal woman presenting with a pelvic mass and a history of weight loss. The patient underwent laparotomy which revealed...
