Abstract
Background Intraabdominal and retroperitoneal leiomyosarcomas are rare cancers, which cause significant morbidity and mortality. Symptoms, treatment and follow up differs from other cancers, and proper diagnosis and treatment of intraabdominal and retroperitoneal leiomyosarcomas is of utmost importance. We performed a systematic review to collect and summarize available evidence for diagnosis and treatment for these tumours. Methods We performed a systematic literature search of Pubmed from the earliest entry possible, until January 2021. Our search phrase was (((((colon) OR (rectum)) OR (intestine)) OR (abdomen)) OR (retroperitoneum)) AND (leiomyosarcoma). All hits were evaluated by two of the authors. Results Our predefined search identified 1983 hits, we selected 218 hits and retrieved full-text copies of these. 144 studies were included in the review. Discussion This review summarizes the current knowledge and evidence on non-uterine abdominal and retroperitoneal leiomyosarcomas. The review has revealed a lack of high-quality evidence, and randomized clinical trials. There is a great need for more substantial and high-quality research in the area of leiomyosarcomas of the abdomen and retroperitoneum. Systematic Review Registration PROSPERO, identifier, CRD42023480527.

Abstract
BACKGROUND Primary tumors of the ischiorectal fossa are rare and comprise a wide array of pathologies with varying malignant potential. Because of the low prevalence, there is a paucity of data in the literature. This article presents a case series on the management of ischiorectal fossa tumors. OBJECTIVE To present experience from 30 years of managing ischiorectal fossa tumors. DESIGN Retrospective single-center analysis. SETTINGS A quaternary referral academic health care center. PATIENTS All patients treated for ischiorectal fossa tumors were included in the study. INTERVENTIONS All patients underwent surgical management of their disease. MAIN OUTCOME MEASURES Disease recurrence and overall survival. RESULTS A total of 34 patients (53% women) were identified with a median follow-up of 23 months. Twenty-one patients (62%) were diagnosed with benign and 13 (38%) with malignant tumors. All underwent surgical resection. The median tumor size was 8.4 cm. R0 resection was obtained in 28 patients. Twelve patients (35%) developed recurrence (9 after R0 resection) after a median time of 6.5 months. There were no surgical-related mortalities. LIMITATIONS Limitations to the study include its retrospective nature, single-center experience, and small patient sample size. CONCLUSIONS Ischiorectal fossa tumors are primarily benign; however, they are associated with high recurrence rates even in the setting of an R0 resection. Treatment should be approached in a multidisciplinary manner, preferably in centers with experience treating these tumors. Close posttreatment surveillance is imperative. See Video Abstract .

Transperineal excision of malignant peripheral nerve sheath tumors of the ischiorectal fossa: Case report of a rare tumor in a frequently forgotten anatomical region. Int J Surg Case Rep 2023; 110:108674.

Abstract
INTRODUCTION AND IMPORTANCE Malignant peripheral nerve sheath tumor is an aggressive tumor that arises from peripheral nerves. Frequently associated with neurofibromatosis, its common localization is in the extremities, trunk (with paravertebral regions), neck and head. Some cases have been found in the pelvis or uterus. In this case report we illustrate one of the rarest localization of this type of tumor in the ischiorectal fossa, with the full recovery of the patient after surgical excision and radiotherapy. CASE PRESENTATION A 61-year-old woman showed a lump near the anus which was initially diagnosed as a lipoma of the right ischiorectal fossa, by Computed Tomography scan. The tumor was completely removed with a minimal skin incision, and the patient had a complete recovery. Only the pathological examination determined the diagnosis of malignant peripheral nerve sheath tumor, in this unusual localization. In consideration of its high aggressiveness the patient underwent radiotherapy. After more than two years of follow-up there is no sign of recurrence. DISCUSSION In sites far from branches of nerves, malignant peripheral nerve sheath tumors can be considered episodic. Ischiorectal fossa is a rare localization, and the differential diagnosis from benign mesenchymal cell tumors can be challenging. When possible, a biopsy should be performed before surgery. CONCLUSION Surgical excision of tumors in ischiorectal fossa should be always complete, in consideration of possible histological surprise.

Abstract
Lipoblastoma is a relatively rare tumor that occurs in infancy and early childhood which arises from embryonic fat. It occurs mostly in trunk and extremities, but abdomen and pelvic lipoblastomas are rare. It presents as a mass with or without mass effect. Computed tomography/magnetic resonance imaging of the abdomen with pelvis is the investigation of choice. We present two cases of pelvic lipoblastoma with extension in ischiorectal fossa and the intra-abdominal lipoblastoma which were excised completely by laparoscopy. We are reporting these cases because of rarity of the disease and feasibility of complete laparoscopic excision.

Abstract
Introduction and importance Colorectal cancer is one of the most common cancers both nationally and internationally. It commonly metastases to local lymph nodes, liver and lungs, with few reported cases of rare sites of metastasis such as adrenal glands, breast and skin. Case presentation We report a 55-year-old-female admitted as case of large bowel obstruction and unintentional weight loss. Computed tomography scan of chest, abdomen and pelvis (CT CAP) showed sigmoid colon circumferential thickening with three lesions in the right hemi-liver. A laparoscopic diverting ileostomy followed by a colonoscopy showed a sigmoidal mass consistent with adenocarcinoma on histopathology. Hence, she received neoadjuvant chemotherapy followed by hepatectomy for the liver metastasis. Post-operatively CT CAP showed a newly developed right ischiorectal fossa (IRF) nodule along with newly developed porta hepatis lymph node. PET scan showed uptake in these two new lesions. Therefore, the patient underwent resection of the primary tumor, porta hepatis lymph node and right ischiorectal fossa nodule excision. The histopathology of the primary tumor came as moderately differentiated adenocarcinoma with both ischiorectal lesion and the porta hepatis nodule being positive for metastatic disease. Clinical discussion & conclusion Ischiorectal fossa tumors are extremely rare with the majority being benign in origin. Nevertheless, the possibility of metastasis is there with no clear explanation regarding the pathway of how the metastatic cells can reach the IRF. Pre-operative diagnosis is important to determine the appropriate approach particularly if the mass is thought to be malignant. Further larger studies are needed to understand the pathway of metastasis to IRF. Colorectal cancer is one of the most common malignancies worldwide. Colorectal cancer has a tendency to metastasize to certain locations like local lymph nodes, liver and lungs. However, the ischiorectal fossa is an extremely rare location for metastatic tumors with vast majority being benign tumors. The ischiorectal fossa hasn't been reported before to be one of the sites of colon cancer metastasis. The exact pathway of metastasis to the ischiorectal fossa remains unknown.

Abstract
Aggressive angiomyxoma is a rare mesenchymal tumour, primarily arising in the soft tissue of the pelvis and perineum in women of reproductive age. There is a paucity of evidence on optimal management because of the rarity of these tumours, but the consensus has been for surgical excision. We present the case of a 65-year-old woman who was admitted with left-sided buttock pain and initially diagnosed with a perianal abscess. She underwent examination under anaesthesia rectum with surgical excision of the lesion, subsequent histopathological and immunochemical analysis was suggestive of aggressive angiomyxoma. To complement our case report, we also present a literature review focusing on aggressive angiomyxoma in the ischioanal fossa (also known as the ischiorectal fossa) with only eight cases of primary aggressive angiomyxoma involving the ischioanal fossa documented to date. The primary aims of this case report and literature review are to familiarise clinicians with the clinical, histopathological and immunochemical features of these tumours, and to increase appreciation that despite the rarity of aggressive angiomyxoma, it might be considered in the differential diagnosis of ischioanal lesions.

Abstract
This is a case of a young healthy woman who presented with left groin pain. On work-up, she was found to have a large, well-defined mass in the ischiorectal fossa with a percutaneous biopsy of only a benign mesenchymal mass. A multidisciplinary team of surgeons (ie, colorectal, orthopaedic, vascular and urological surgery) collaborated in planning and performing the extirpation of the tumour. Final histopathology identified the tumour to be an aggressive angiomyxoma, a benign tumour with a high predilection for local recurrence. The patient had an uneventful postoperative course, with maintenance of good functional status.

Abstract
BACKGROUND Ischiorectal fossa tumors are rare. OBJECTIVE This study reviews a single institution's series of ischiorectal tumors with comparison against presacral tumors and assesses the utility of preoperative biopsy and angioembolization. DESIGN This is a retrospective study. SETTINGS This study was conducted at a quaternary referral center. PATIENTS All patients with ischiorectal tumor treated between February 1995 and April 2017 were retrospectively reviewed. Tumors extending secondarily into the ischiorectal fossa and inflammatory pathologies were excluded. INTERVENTIONS Preoperative biopsy, neoadjuvant therapy, angioembolization, and surgical excision of these tumors were reviewed. MAIN OUTCOME MEASURES Demographic, perioperative, pathological, and oncologic outcomes were evaluated. RESULTS Twenty-four patients (15 female; median age 54) were identified. Two-thirds were symptomatic. Forty-six percent had a palpable mass. All patients had CT and/or MRI. Fifty percent had a preoperative biopsy, of which 83% were diagnostic, and management was altered in 50%. All patients underwent surgical excision. Fifty-five percent had local excision, 38% had radical pelvic excision, and 8% had total mesorectal excision. Two patients had preoperative angioembolization. Both had successful R0 local excision. Morbidity occurred in 25%, with 1 major complication. There was no 30-day mortality. Histopathology demonstrated 17 soft tissue tumors (3 malignant), 2 GI stromal tumors, 1 neuroendocrine tumor, 1 Merkel cell carcinoma, 1 basaloid carcinoma, 1 epidermal cyst, and 1 lipoma. R0 resection was achieved in 75%. All patients were alive after a median follow-up of 33 months. Four patients developed recurrence at a median 10 months postoperatively. All recurrences were malignant, and 75% had had a R1 resection. LIMITATIONS This study is limited by its small numbers. The quaternary institution source may introduce bias. CONCLUSIONS Ischiorectal fossa tumors are heterogeneous and more likely to be malignant than presacral tumors. Biopsy can be useful if a malignant diagnosis is suspected and changes management in 50% of cases. Preoperative embolization may be useful for large vascular tumors. R0 resection is important to minimize recurrence. See Video Abstract at http://links.lww.com/DCR/A779.

[PMID: 30284069 PMCID: PMC6170515 DOI: 10.1186/s40792-018-0533-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Accepted: 09/21/2018] [Indexed: 01/19/2023] Open
Abstract
Background A solitary fibrous tumor (SFT) is a rare mesenchymal tumor that occurs mostly in pleural sites, and an SFT occurring in the ischiorectal fossa is extremely rare. Because of the rarity, there are few reports detailing an SFT in the ischiorectal fossa. Case presentation A pararectal tumor was incidentally found in a 42-year-old man during a routine medical examination. The patient had no symptoms and no previous medical history. In the physical examination, a smooth-margined and hard elastic mass was felt, and in a digital rectal examination, the rectal mucosa appeared normal. A computed tomography (CT) scan showed a 5-cm, well-defined, solid mass in the left ischiorectal fossa. Contrast-enhanced CT in the early phase showed intense heterogeneous enhancement that persisted during the delayed phase. T2-weighted images of magnetic resonance imaging yielded heterogeneous intermediate and low signal intensity. Intense arterial enhancement suggested a hypervascular nature, and persistent delayed enhancement and low signal bands on T2-weighted images suggested a fibrous component of the mass. An SFT was suspected. Most SFTs are benign but have malignant potential. Our patient did not hope for surgery if the tumor was benign; therefore, an ultrasound-guided transperineal core needle biopsy was performed to decide on a treatment strategy. Microscopic examination showed tumor cells appearing as spindle and fibroblast-like cells within a collagenous stroma. Immunohistochemistry identified CD34 and vimentin, supporting the diagnosis of an SFT. The patient consented to excision of the mass. He was placed in a prone jackknife position, and the tumor was removed transperineally using a posterior approach (modified Kraske procedure). The levator ani muscle, external sphincter muscles, and rectum were not involved and separated from the tumor. The tumor was successfully resected en bloc with no complications. Five uneventful days post surgery, the patient was discharged. There was no local recurrence during the year following surgery. Conclusion Imaging findings reflect the tissue characterization such as hypervascularity and fibrous nature of SFTs. We have presented a rare case of an SFT in the ischiorectal fossa with useful imaging findings for diagnosis, treatment strategy, and successful surgical removal using a posterior approach.
