“…Complete surgical resection with tumor-free resection margins is the treatment of choice [ 3 , 5 , 7 , 16 , 22 , 24 , 31 – 34 ]. The extent of resection depends, among other factors, on the risk of malignancy [ 31 ].…”

“…In the literature, a posterior approach (e.g., Kraske procedure) is classically described for the resection of retro- or pararectal tumors, especially in cases of tailgut cysts [ 5 , 30 , 36 ]. Alternatives are transabdominal, transvaginal, transrectal, or combined approaches [ 30 , 31 , 34 , 37 , 38 ]. Abdominoperineal resection or robotic-assisted resection has also been described [ 25 , 39 ].…”

Purpose Solitary fibrous tumors (SFT) are a rare entity of in majority benign neoplasms. Nevertheless, up to 20% of cases show a malignant tendency with local infiltration or metastasis. Commonly arising in the thoracic cavity, only few cases of SFT of the mesorectal tissue have been reported in the literature. Complete surgical resection, classically by posterior approach, is the treatment of choice. The purpose of this review is to demonstrate the safety and suitability of transanal minimally invasive surgery (TAMIS) as a surgical approach for the resection of benign pararectal solid tumors. Methods We report the case of a 52-year-old man who was diagnosed incidentally with SFT of the distal mesorectum. Resection by TAMIS was performed. Based on this case, we describe the steps and potential benefits of this procedure and provide a comprehensive review of the literature. Results Histopathology confirms the completely resected SFT. After uneventful postoperative course and discharge on day four, follow-up was recommended by a multidisciplinary board by clinical examination and MRI, which showed a well-healed scar and no recurrence up to 3 years after resection. Conclusion SFT of the mesorectum is a very rare entity. To our knowledge, this is the first report on a TAMIS resection for SFT, demonstrated as a safe approach for complete resection of benign pararectal solid tumors.

“…IMT with epithelioid morphology is particularly aggressive and has been reclassified as epithelioid inflammatory myofibroblastic sarcoma. SFTs are exceedingly rare in the gastrointestinal tract [71][72][73][74][75][76][77][78][79][80][81][82]. Histologically, SFTs are usually hypercellular and consist of spindle cells arranged in a storiform pattern, hemangiopericytoma-like vascular pattern, and bands of hyalinized collagen [83].…”

Inflammatory fibroid polyp (IFP), initially considered a reactive process, is now recognized as a benign mesenchymal neoplasm of the gastrointestinal tract. We report a case of a 68-year-old woman with medically refractory Crohn disease that presented with intussusception requiring surgical intervention. The resection revealed a jejunal mass consisting of a submucosal proliferation of bland spindle cells in a fibrous stroma infiltrated by numerous eosinophils. By immunohistochemistry, the lesion was positive for vimentin and negative for desmin, smooth muscle actin (SMA), S-100, CD117, DOG1, ALK (D5F3), Melan-A, HMB-45, CD34, and STAT6. Ki-67 proliferative index was low (<1%). The mass was classified as IFP by its characteristic morphology and associated eosinophilia. IFP should be considered in the differential diagnosis of adults with intussusception or bowel obstruction. Definitive treatment typically requires surgical resection of the involved bowel segment.

“…Reports of SFTs originating in the bowel itself are rare, although a few cases of SFTs originating in the intestinal mesentery have been reported [ 7 , 15 , 16 ]. Liu et al describe a case in which an SFT surgically excised from the small bowel mesentery was found to be responsible for a chronic abdominal mass, but the patient did not experience obstructive symptoms [ 7 ].…”

Solitary fibrous tumors are rare tumors of mesenchymal origin. Although most often observed in the lung pleura, they have been reported in varied extrapleural sites. A 70-year-old male with complicated Crohn’s disease presented with 3 days of nausea, emesis, constipation, and abdominal pain. Computed Tomography (CT) demonstrated mucosal thickening of the middescending colon, consistent with fibrosing stricture. Surgical excision revealed an unusual, 5 cm mass originating in the subserosa. Histopathology of the lesion was notable for a proliferation of cells with spindle and stellate-shaped nuclei and no appreciable mitotic figures, which extended into the muscularis and submucosa. Immunohistochemistry was STAT6 nuclear positive and cytoplasmic CD34 positive, diagnostic for solitary fibrous tumor (SFT). In this case, the SFT infiltrating into the muscularis propria and subserosa caused the stricture and bowel obstruction. This illustrates that while fibrosing strictures are usually the etiology of bowel obstruction in the setting of Crohn’s disease, other rare possible causes should be considered.
