Introduction and Importance: Hydatid disease, caused by the zoonotic parasite Echinococcus granulosus, presents as cysts most commonly in the liver and the lungs. A hepato-pleural fistula is considered one of its complications and surgery remains the mainstay of treatment. A simultaneous invasive thoracic and abdominal access is routinely needed which is accompanied by increased morbidity and mortality., Case Presentation: In this case report, we present an innovative, less invasive, non-classical approach., Clinical Discussion: We introduce a successful transabdominal transdiaphragmatic laparoscopic technique for the management of a hepato-pulmonary fistula secondary to hydatid disease of the liver., Conclusion: Compared to the classical method, this new surgical approach towards hepato-pulmonary fistula paves the way for minimally invasive surgeries to manage complicated hydatid disease with a lower mortality and morbidity, faster recovery and shorter hospital stay. The work has been reported in line with the SCARE 2020 criteria., (Copyright © 2022. Published by Elsevier Ltd.)

Introduction: Malignant mesothelioma is a rare neoplasm of mesothelial cells arising most frequently in the pleura or peritoneum and less frequently in the liver., Case Presentation: We present a case of primary hepatic mesothelioma of 41year old woman. She had no history of asbestos exposure or cancer. Abdominal computed tomography (CT) showed 21cm intrahepatic mass in the right lobe with many cystic lesions and few small calcifications. Pathology showed a biphasic cellular pattern. In addition, the tumor cells were positive for Calretinin, Creatine Kinase (CK)5/6, CK7, CKAEI 1/3, Wilms Tumor protein (WT-1), and Vimentin, but were negative for Alpha Feto protein (AFP), Thrombotic Thrombocytopenic Purpura (TTP-1), Anti-Hepatocyte Specific Antigen (HSA), Synaptophysin, CK20, and Homeobox protein (CDx-2)., Discussion: Primary intrahepatic mesothelioma (PIHMM) is not included in the classification of the World Health Organization classification of hepatic tumors. Mesothelial cells are not normally found in the liver, but some reported cases suggest it may grow from the mesothelial cells of the Glisson's capsule., Conclusion: The probability of hepatic mesothelioma should not be ruled out, even in a young woman without a clear history of asbestos exposure., (Copyright © 2016 The Author(s).

Introduction: Aggressive angiomyxoma is a rare mesenchymal tumor occurring predominantly in the pelvi-perineal region. It is more common in females during their reproductive age. Our focus is on the surgical approach for a recurrent angiomyxoma., Case Presentation: We present a case of a 36-year-old female patient with a recurrent lower back and perineal bulges. One year ago, she had the same presentation and underwent resection of that mass in a peripheral hospital without available information. Five months later, she started to have the same bulge. Computed tomography scan and true cut biopsy were suggestive of angiomyxoma with single lung metastasis. The decision was to proceed with resection through a transabdominal and perineal incision, even in the presence of metastasis since it's a very slow growing tumor with long life expectancy. The pathology was consistent with aggressive angiomyxoma., Discussion: 90% of patients with angiomyxoma are women. Although it is benign, the tumor is still aggressive because of the high rate of local recurrence after resection. Angiomyxoma is a mesenchymal tumor, composed of fibroblasts within a myxoid background. Treatment is usually through wide local excision to achieve an R0 resection. Our approach was through a transabdominal and perineal incision, which allowed full control and mobilization of the tumor without disrupting the capsule. This surgical approach was not described previously in the literature., Conclusion: The principle to achieve cure in aggressive angiomyxoma is by optimizing exposure through two different incisions, wide excision while keeping the capsule intact and removing enbloc any invaded organ., (Copyright © 2016 The Authors.

Introduction: Gastric glomus tumors are fairly uncommon and mostly benign, with an estimated incidence of 1% of all GI soft tissue tumors. The most common GI site of involvement is the stomach, and in particular the antrum. Some cases have been discovered incidentally, but most are symptomatic presenting with GI bleeding, perforation or abdominal pain. Glomus tumors are submucosal tumors and hence mistaken with the more frequent gastrointestinal stromal tumors., Presentation of Case: A 33-year-old woman presented with intermittent dull upper abdominal pain for two days. Abdominal computed tomography (CT) was performed showing a hyperdense mass in the antrum. Endoscopy and endoscopic ultrasound revealed a submucosal antral mass along the greater curvature, suspicious for a gastrointestinal (GI) stromal tumor (GIST), a laparoscopic antrectomy with Billroth I reconstruction was done. Pathological examination revealed that the mass was a gastric glomus tumor., Discussion: The presented case report met all the usual standard criteria commonly used to identify glomus tumors, the uniqueness of the case lies in the occurrence of the glomus tumor in the stomach, first suspected as GIST, then confirmed as a gastric glomus tumor. The vast majority of glomus tumors of the GI tract have been described in the gastric antrum. They occur in adults of all ages with a significant female predominance (78%)., Conclusion: This case may aid in improving the recognition and diagnosis of this rare entity and in differentiating it from more common GISTs and gastric carcinoids. A built up knowledge between physicians is extremely necessary to avoid common confusion in taking the right medical approach., (Copyright © 2014 The Authors. Published by Elsevier Ltd..

Background: Malignant fibrous histiocytoma, a subtype of primary lung sarcoma is a very rare disease. It usually presents as a lung nodules and the final diagnosis is made by immunohistochemical studies., Methods: A 45-year-old patient presented with progressive dyspnea, dry cough and right shoulder pain. Chest X-ray revealed complete opacification of the right hemithorax. Chest computed tomography confirmed the presence of a heterogeneous lesion occupying the whole right hemithorax causing a mass effect on the trachea. Ultrasound guided biopsy was done and final pathology was suggestive of malignant fibrous histiocytoma., Conclusion: Progressive dyspnea in young otherwise healthy patients should be investigated early on. In our case the presence of right shoulder pain indicates advance disease illustrated by the singular imaging findings., (Copyright © 2014 The Authors. Published by Elsevier Ltd..
