“…Of all omental tumors, metastatic malignant tumors are the most common, and they mainly occur in the stomach, colon, pancreas, and ovary[ 1 ]. Primary peritoneal tumors are rare and can be benign or malignant, accounting for approximately 50% each[ 2 ].…”

BACKGROUND The most common causes of scrotal enlargement in patients include primary tumor of the scrotum, inflammation, hydrocele of the tunica vaginalis, and indirect inguinal hernia; scrotal enlargement caused by external tumors of the scrotum is rare. The patient had both a greater omentum tumor and an inguinal hernia, and the tumor protruded into the scrotum through the hernia sac, which is even rarer. Moreover, omental tumors are mostly metastatic, and primary omental fibroma is rare. CASE SUMMARY Here, we report a rare case of a 25-year-old young man with scrotal enlargement and pain for 3 months. Preoperative examination and multidisciplinary discussions considered intra-abdominal tumor displacement and inguinal hernia, and intraoperative exploration confirmed that the greater omentum tumor protruded into the scrotum. Therefore, tumor resection and tension-free inguinal hernia repair were performed. The final diagnosis was benign fibroma of the greater omentum accompanied by an indirect inguinal hernia. CONCLUSION This unusual presentation of a common inguinal hernia disease illustrates the necessity of performing detailed history taking, physical examination, and imaging before surgery.

“…IHC markers also helped to differentiate SFT from its differential diagnoses in a study by Rao et al in which a child was presented with a congenital mass 22 . Guo et al showed that histological tests in addition to gene sequencing could help to distinguish a malignant SFT of the greater omentum which was first suspected as a GIST 23 . Lau and colleagues also showed the importance of IHC methods in SFT diagnosis by providing a rare SFT case (with small intestinal mesentery origin) which has some similarities to a GIST on imaging 24 …”

“…The incidence rate of SFTs remains at 1 case/million individuals/year ( 5 ). Notably, the majority of SFTs occur in the thoracic cavity; however, previous studies have demonstrated the occurrence of SFTs throughout extrathoracic sites, such as the retroperitoneal space ( 6 ), meninges ( 7 ), orbit ( 8 ), breast ( 9 ), thyroid gland ( 10 ), pericardium ( 11 ), parotid gland ( 12 ), spine ( 13 ), pelvic cavity ( 14 ), omentum ( 15 ), perineum ( 16 ), bladder ( 17 ), prostate ( 18 ), external auditory canal ( 19 ), pancreas ( 20 ) and, less often, in the liver ( 21 ).…”

Multidisciplinary collaboration for the successful treatment of a giant hepatic solitary fibrous tumor protruding into the thorax: A case report

Solitary fibrous tumors (SFTs) are composed of spindle cells and collagen fibers, and these form rare mesenchymal tumors. SFTs are most frequently observed in intrathoracic sites; however, they may also occur in extrathoracic sites, such as the liver. Unlike the hepatic SFTs (HSFTs) reported in the literature, the SFT detailed in the present case report was a large tumor that originated from the liver, with a dumbbell-shaped growth through the diaphragm into the right thoracic cavity. This posed substantial challenges in both diagnosis and treatment. Thus, the present report outlines the findings of a multidisciplinary team meeting that was used to discuss and develop an optimal and personalized treatment strategy for the patient. Transhepatic arterial embolization was performed to block the major arterial blood supply to the tumor in order to reduce its size. Subsequently, the tumor was fully resected, following the collaboration of the experienced hepatobiliary and thoracic surgeons. Following surgery, the abdominal distension experienced by the patient ceased, and no tumor recurrence was detected at the 1-year follow-up. In conclusion, due to limited previous reports of HSFT treatment using multidisciplinary collaboration, the present study outlined the treatment used for this specific tumor type, and the corresponding literature was reviewed.
