“…Abdominal solitary fibrous tumours have been described in the liver, stomach, kidney, adrenal glands, urinary bladder, prostate gland and uterus. 4 A solitary fibrous tumour in the mesocolon is an extremely rare clinical entity and, to the best of our knowledge, there are only two other cases in the literature, both reporting a tumour in the mesocolon. 2,3 Extrapleural solitary fibrous tumours are most commonly observed in adults with a wide age range of 20-70 years and tend to affect both genders equally.…”

“…1 They are usually slow-growing, painless masses with no clinical symptoms, unless they compress adjacent anatomical structures. 2,4 They can be detected via imaging techniques such as MRI or computed tomography. Macroscopically, most solitary fibrous tumours are well circumscribed, frequently encapsulated masses that are 1-25 cm in size.…”

“…2 The histological differential diagnosis of extra-pleural solitary fibrous tumours includes tumours with mesenchymal contents such as desmoid, inflammatory pseudotumor, mesenteric fibromatosis, gastrointestinal stromal tumour, desmoplastic mesothelioma, leiomyoma and leiomyosarcoma. 4 Immunohistochemical studies are essential to differentiate spindle-cell tumours. A vast majority of solitary fibrous tumours stain positive for CD34, STAT6, Bcl2, CD99, beta-catenin, vimentin and are usually negative for actin, desmin, h-caldesmon, smooth muscle actin and CD117.…”

Solitary fibrous tumours are rare mesenchymal tumours which mostly arise from pleura. Such tumours occurring in the mesocolon are exceptionally rare. A 35-year-old man was referred to the general surgery department with a painless and nonpalpable mass in the right quadrant of the abdomen, which was detected incidentally on magnetic resonance imaging. The patient had no symptoms and the physical examination revealed no findings. The patient underwent surgical resection and excisional biopsy results revealed an intra-abdominal solitary fibrous tumour originating from the ascending mesocolon. He was discharged two days after surgery and remained disease-free at the end of the two-month follow-up period.

“…SFT were originally described in the pleura by Klemperer and Rabin in 1931,4 consistent with most series finding a thoracic origin in up to 70% of the cases (80% pleural, 10% mediastinal and 10% intrapulmonary) 5. Today, SFT are known to arise from many extrathoracic tissues including but not limited to head and neck, retroperitoneum, peritoneum, abdomen, meninges, orbit, upper respiratory tract, salivary glands, thyroid, liver, adrenal gland, kidney, spermatic cord, urinary bladder, prostate, uterine cervix, spinal cord and periosteum 4…”

“…Tumour markers found on SFT include CD34 (present in over 95% of cases) and Bcl-24; however, their lack of expression does not rule out the presence of SFT 10. In fact, low expression of CD34 and high expression of IGF2 are significantly associated with malignant transformation and might be a target of individualised therapy 6.…”

Solitary fibrous tumours (SFTs) are rare tumours arising from mesenchymal tissues. Despite of their more frequent occurrence in the pleura, SFT can present anywhere in the body. Only a few cases have been described arising from the mesentery. Most tumours have a benign nature; however, up to 20% of them can spread, most commonly to liver, lung and bone. Surgical excision including all surrounding tissues remains the treatment of choice; however, there is no consensus regarding the need for adjuvant therapies. We present a 79-year-old man with abdominal pain who was found to have a SFT in the mesentery of the sigmoid colon, treated with en bloc resection. A multidisciplinary team including surgeons, medical and radiation oncologists is recommended in the care of these patients.

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.
