Pelvic masses frequently originate from the pelvic cavity and are often associated with uterine, ovarian, or intestinal disorders. This report describes the case of a patient with a pelvic mass diagnosed as a retroperitoneal dermoid cyst at our hospital. We analyzed this case and conducted a literature review, to mitigate the risk of misdiagnosis and enhance the treatment of retroperitoneal masses.

An ectopic kidney is a rare congenital defect that is often asymptomatic, but can be incidentally discovered during imaging examinations. Moreover, the morphological characteristics and laboratory features of ectopic kidneys are nonspecific, which may lead to misleading diagnostic approaches, particularly when there are additional factors, such as infection, obstruction, or other anomalies. A 43-year-old female presented with a mass in the left adnexal area. She had septate uterus and a history of congenital urinary incontinence. Ultrasound and MRI findings indicated that the mass was a cyst originating from the ovary. However, it is possible that the lump was derived from the urinary system. To confirm the diagnosis, laparoscopy was performed, followed by pathological examination, which confirmed the presence of an ectopic kidney with a single-system ectopic ureter. The patient underwent nephroureterectomy, and her symptoms successfully resolved, leading to a favorable prognosis. This case report highlights a rare case involving an ectopic kidney with a vaginal ectopic ureter that initially presented as an adnexal cyst and caused urinary dribbling. This case emphasizes the importance of early recognition and accurate diagnosis in women with similar symptoms.

Meigs syndrome is a classic triad of ascites, pleural effusions, and an ovarian fibroma with resolution following excision. Pseudo-Meigs syndrome presents similarly but is caused by a pelvic mass other than an ovarian fibroma, such as a fibroid. We present a case report of a 33-year-old gravida 2 para 0-0-1-0 woman with a massive, pedunculated fibroid who developed rapid onset of ascites and edema beginning at 5 weeks of gestation. Malignant, cardiac, renal, hepatic, and rheumatologic causes were ruled out. Her symptoms resolved following myomectomy and delivery via cesarean. Pseudo-Meigs syndrome was suspected. Pseudo-Meigs syndrome is a diagnosis of exclusion and requires surgical management for resolution. Pregnancy may be an inciting factor. Myomectomy may be done safely at the time of cesarean.

We present a rare case of a female pelvic solitary fibrous tumor unsuccessfully resected using single-port laparoscopy, requiring conversion to laparotomy. Although the resection was successful, the surgical approach could have been improved. For large tumors, minimally invasive results are possible with flexible choices of equipment and incision position.

Castleman disease (CD) is a rare lymphoproliferative disorder characterized by localized (unicentric) or systemic (multicentric) lymphadenopathy. This study presents a unique case of a 29-year-old female with a rare pelvic presentation of unicentric Castleman disease, specifically the hyaline vascular variant. Despite surgical resection, an unresectable residual lesion prompted adjuvant radiotherapy and subsequent chemotherapy. The literature highlights surgical resection as the primary treatment for localized Castleman disease; however, radiotherapy and combined chemotherapy regimens like cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) have shown promise in unresectable cases, emphasizing a multidisciplinary approach. This case underscores the importance of tailoring treatment strategies for uncommon Castleman disease presentations.

A 48-year-old man with a medical history of hypertension and no family history of prostate cancer presented with abdominal distension, lower abdominal pain, and lower urinary symptoms. Physical examination revealed a palpable mass in the lower abdomen, and a digital rectal examination detected a firm mass on the anterior side of the rectum. Laboratory tests showed an elevated PSA level (7.9 ng/mL). Imaging studies indicated a solid mass connected to the prostate\'s posterior and rectum\'s anterior walls, along with bladder compression. Transperitoneal biopsy and histological analysis led to a diagnosis of a stromal tumor with uncertain potential malignancy. Considering the absence of apparent malignancy signs and the smooth outer wall of the tumor, the patient underwent, for the first time in the literature, a robot-assisted radical extraperitoneal prostatectomy for complete macroscopic resection. The surgery involved excision of the bulky pelvic mass, preservation of the urethra, and anatomical reconstruction. The postoperative course was uneventful, and we discharged the patient with no complications. The pathological examination documented the diagnosis of multilocular prostatic cystadenoma. Post-surgery follow-up examinations, including PSA levels and imaging scans, showed no signs of tumor recurrence. At the 3-, 6-, and 9-month follow-ups, the patient was asymptomatic and had fully recovered, with no urinary or sexual dysfunction reported.

Vulvar leiomyomas are extremely rare smooth muscle tumors that are easily mistaken for other lesions, as the differential diagnosis must consider a wide spectrum of benign and malignant lesions. We present the case of a 52-year-old woman with a three-year history of progressive abdominal distension and pain and an enlarging vulvar mass distorting the labia majora and causing gait disturbance. Imaging confirmed an enormous pelvic mass originating in the uterus, compatible with a leiomyoma/sarcoma, and large perineal and vulvar masses with similar characteristics. Histopathology after surgical removal revealed benign abdominal, vulvar, and perineal leiomyomas. This case highlights the rarity and diagnostic challenges of extra-uterine leiomyomas, particularly those in the vulvar region.

A 37-year-old lady, when being evaluated in gynecology for pain in the abdomen, was found to have a pelvic mass suspicious of ovarian cancer with markers negative. There was an ovarian vein thrombosis extending to the right atrium in the contrast-enhanced computed tomography scan. A fluorodeoxyglucose positron emission tomography-computed tomography ruled out any other lesions. The patient underwent surgery under general anesthesia with transesophageal echocardiography to monitor the atrial thrombus. Intraoperatively, a retroperitoneal mass is seen arising from the right adnexal region of the uterus extending to the lumbar area. After the hysterectomy, bilateral salpingo-oophorectomy, tumor resection, and baring and looping of the retroperitoneal vessels, a sternotomy was done, and she was put on cardiopulmonary bypass. The tumor thrombus had two limbs both arising from the mass, one through the ovarian and the second through the iliac veins and joining together inside the inferior vena cava (IVC). With the excision of the ovarian vein at its junction, atrial incision, and incisions over the iliac veins and IVC, the thrombus was removed completely in a single sitting. Final histopathology revealed intravenous leiomyomatosis and no malignancy. We report this case as a rare disease, with both ovarian and iliac thrombus being a further rarity and a multidepartment joint effort with a successful outcome.

Cervical adenocarcinoma accounts for 10%-25% of total cases of cervical carcinoma. But in recent years, the incidence of adenocarcinoma has risen both proportionally and absolutely. Clinically, most cervical adenocarcinoma show no symptom or present with abnormal uterine bleeding or vaginal discharge, similar to squamous cell carcinoma. What different about it is that cervical cytological testing demonstrates a high false-negative rate of cervical adenocarcinoma, potentially leading to the failure in detecting in early stage. This report presents two cases both with pelvic masses, and massive ascites served as the initial symptom, which is similar to the clinical symptom of ovarian cancer, but ultimately diagnosed with cervical adenocarcinoma through surgical specimens. There are few literature reports on this situation. Hence, a literature review also has been performed to improve the recognition for cervical adenocarcinoma presenting with pelvic masses and massive ascites, and to avoid misdiagnosis.

Scrotal epidermoid cysts are rare. Intratesticular epidermoid cysts are more common than extra scrotal cysts and are the most commonest benign tumors of the testicles. Midline scrotal raphe cysts are reported, but only a few have intrapelvic extensions deep into the pelvis. A nine-year-old boy presented with a painless scrotal swelling. Magnetic resonance imaging (MRI) of the pelvis confirmed the cystic nature with an extension of the swelling up to the base of the prostate. On surgical exploration, the cyst had a tapering stalk with cranial extension up to the base of the prostate. The patient underwent an excision of the cyst and made an uneventful recovery and was asymptomatic at the end of three months of surgery. The histopathology of the lesion was typical of an epidermoid cyst. Extratesticular scrotal epidermoid cysts with pelvic extension are a rarity with less than five cases reported in the literature. Our case stands to be the youngest reported case of a scrotal epidermoid cyst based on our knowledge. Scrotal epidermoid cysts are a very rare and benign entity, and upon recognition and confirmation of the extent of spread, extratesticular scrotal cysts can safely be removed. No other management may be required with no recurrences reported.
