Endometriosis is defined as the growth of functional endometriotic gland and stroma outside the uterine cavity. Although it is common in women of reproductive age, extragenital endometriosis is considerably rare. Due to its frequent localization at the rectosigmoid junction in the gastrointestinal system, endometriosis may manifest with abdominal pain, constipation, and rectal bleeding. Gastrointestinal stromal tumor is the most common mesenchymal tumor of the gastrointestinal system and develops from the muscularis propria. Its extraluminal component is prominent. This study aimed to report a rare case of a 37-year-old patient who was operated with laparoscopic colon resection for a malignant-appearing submucosal mass with indistinct borders at the rectosigmoid junction that received the final diagnosis in histopathological examination. Endometriosis should be considered in the differential diagnosis of non-specific gastrointestinal symptoms in female subjects of reproductive age as the one reported here.

Jejunal Gossypiboma Mimicking a Gastrointestinal Stromal Tumor: A Case of a Rare Iatrogenic Complication and Review of the Literature.

The term "gossypiboma" or "textiloma" is used to describe a mass of retained cotton matrix and the surrounding inflammatory response inside a body cavity following surgical intervention. The precise incidence of this phenomenon is uncertain, as cases are frequently underreported due to concerns related to medical malpractice. This rare complication poses a diagnostic dilemma due to the non-specific clinical and radiological features, which can result in significant morbidity and mortality.

Introduction: Liquid biopsy as a non-invasive method to investigate cancer biology and monitor residual disease has gained significance in clinical practice over the years. Whilst its applicability in carcinomas is well established, the low incidence and heterogeneity of bone and soft tissue sarcomas explains the less well-established knowledge considering liquid biopsy in these highly malignant mesenchymal neoplasms.
Materials And Methods: A systematic literature review adhering to the PRISMA guidelines initially identified 920 studies, of whom 68 original articles could be finally included, all dealing with clinical applicability of liquid biopsy in sarcoma.
Novel Therapeutics in Soft Tissue Sarcoma.

Sarcoma Unit, The Royal Marsden Hospital and Institute of Cancer Research, London SW3 6JZ, UK.
There has been noteworthy progress in molecular characterisation and therapeutics in soft tissue sarcomas. Novel agents have gained regulatory approval by the FDA. Examples are the tyrosine kinase inhibitors avapritinib and ripretinib in gastrointestinal stromal tumours (GIST), the immune check point inhibitor atezolizumab in alveolar soft part tissue sarcoma, the γ-secretase inhibitor nirogacestat in desmoid tumours, the NTRK inhibitors larotrectinib and entrectinib in tumours with fusions, the mTOR inhibitor nab-sirolimus in PEComa, and the EZH-2 inhibitor tazemetostat in epithelioid sarcoma.

Medicine (Baltimore)

Department of Pathology, Keck School of Medicine, University of Southern California, Los Angeles, CA.
Rationale: Solitary fibrous tumors (SFTs) are spindle cell tumors that typically occur in the pleura and peritoneum, but very rarely in the stomach. To our best knowledge, there are only 10 cases reported in English literature. We reported a case of primary stomach SFT and summarized the characteristics of all previous cases, suggesting that pathologists and surgeons should include this disease in the differential diagnosis list of primary mesenchymal tumor of the stomach.

Department of Gastroenterology, Zhongda Hospital Southeast University, Nanjing, China.
Background: The aim of this study was to verify the safety and efficacy of endoscopic resection (ER) for gastric gastrointestinal stromal tumors (GISTs).
Methods: Among a consecutive series of resections for gastric GISTs performed in a single center, the outcomes of patients who had ER were compared to standard surgical resection (SR).
Results: In the cohort, 329 consecutive primary localized gastric GISTs patients (, ER/SR = 251/78) were enrolled.
