Intestinal obstruction is one of causes of acute abdomen leading to laparotomy. Even though there are different causes of small bowel obstruction (SBO), internal hernia is a rare one. Though different types of internal hernias occur, herniation through the mesoappendix is reported only four times in the literature.
Case presentation
We describe here such a type of hernia on a 50 yrs old male presented with symptoms and signs of SBO whose cause was diagnosed to be internal hernia through mesoappendix intraoperatively. He was managed with appendectomy and release of the hernia.
Clinical discussion
Intestinal obstruction is a common cause of acute abdominal conditions and can lead to significant mortality if not managed appropriately. Internal hernias account for less than 1 % of intestinal obstruction cases. The cause of trans-mesoappendicular internal hernias remains largely unknown. A congenital defect in the mesoappendix may contribute to the development of these hernias.
Conclusion
In patients with acute intestinal obstruction without previous surgery, internal hernia should be considered as a differential diagnosis. Trans-mesoappendicular hernia is extremely rare type of internal hernia.

Introduction and importance: Stability of the peroneal tendon and lateral ankle structure is essential. Appropriate treatment is mandatory to improve the outcome.
Case presentation: A 47-year-old female has had ankle pain for around six months. She has a history of falling while getting downstairs. A physical examination around the lateral ankle revealed slight local swelling and tenderness. Advanced radiography shows peroneal inflammation, subluxation, and an Anterior Talo-Fibular Ligament (ATFL) tear. The patient was diagnosed with peroneal tendinitis with subluxation of the peroneal longus tendon and ATFL tear.
Clinical discussion: We performed an open procedure with debridement, tubularization, and superior retinaculum repair, followed by ATFL repair using a modified Brostorm-Gould technique to stabilize the ankle. The outcomes of the Foot and Ankle Disability Index (FADI) and Visual Analogue Scale (VAS) were evaluated, and they showed promising results after treatment.
Conclusion: Appropriate treatment should be performed to manage lateral ankle pain. A peroneal subluxation accompanied by an ATFL tear could be treated by an open procedure with debridement, tubularization, and superior retinaculum repair, followed by a modified Brostorm-Gould procedure. All these subsequent procedures are valuable and straightforward techniques for managing ankle stabilization.

Introduction and importance: The importance of preoperative tumor site marking has increased over the years, as the method of intraoperative primary lesion identification and determination of resection margins is one factor determining whether oncological safety and function-preserving gastrectomy are possible during surgery. We hypothesize that preoperative placement of the near-infrared fluorescent (NIRF) clip, ZEOCLIP FS, near the oral incision line of the gastric tumor will allow for Firefly recognition of the NIRF clip on da Vinci during surgery and easy determination of the tumor location and incision line. Hence, we report on two cases in which the procedure was performed.
Case presentation: Case 1: A 62-year-old woman was diagnosed with early gastric cancer of 35 mm in size located in the greater curvature of the gastric angle and underwent robot-assisted distal gastrectomy. NIRF clips were placed around the negative biopsy-confirmed area on the tumor's oral side by endoscopy on the day before surgery. The clips were identified intraoperatively in Firefly mode, and we performed gastrectomy without using an intraoperative endoscope. Case 2: A 60-year-old man was diagnosed with early gastric cancer 40 mm in size on the anterior wall of the gastric angle and underwent robot-assisted distal gastrectomy. Similarly, NIRF clips were placed around the site of negative biopsy confirmation the day before surgery. NIRF clips were identified, and we performed gastrectomy.
Clinical discussion: The time taken to mark the gastric resection line after activating the Firefly imaging system was 120 and 154 s, respectively, and intraoperative endoscopy was not required. The advantage of our two-step method is that a surgeon can mark the clips the day before the surgery, even if they are not endoscopists. Increasing the recognition rate of fluorescent clips and preventing their remains are future issues.
Conclusion: Based on the results of the above two cases, ZEOCLIP FS is influential in determining the tumor's location and the resection line.

Introduction: Although shim dislocation is one of the post-UKA complications, the repeated shim dislocations early after the operation are rarely reported. Currently, no consensual clinical guideline for the reliable prevention and proper management of this complication has been available.
Case presentation: Two years ago, a 60s old female patient came to the hospital for treatment due to left knee joint pain for more than 10 years and the failure to release her suffering via conservative treatment. Given the evidence of X-ray (Fig. 1), the patient was diagnosed as left knee medial compartment osteoarthritis and was hospitalized for surgical treatment.
Clinical discussion: For a mobile platform UKA, whether it is an initial liner dislocation or a re-dislocation, revision to TKA is optimal when the underlying cause of the dislocation cannot be determined or corrected.
Conclusion: Standardized and precise surgical procedures as well as postoperative patient instructions are key factors in avoiding complications.

Introduction and importance
Eosinophilic mastitis is a very rare but benign entity of complex pathogenesis. Most cases present similar to breast carcinoma, which makes it a challenging condition to diagnose. We report the sixteenth case of eosinophilic mastitis and the third case without systemic demonstrations. In this paper, we present the first case of eosinophilic mastitis from Syria and the third isolated one in the literature.
Case presentation
This case report discusses a 38-year-old female patient presented to the clinic of thoracic surgery at the Hospital on January 2020 with a pain and swelling in the left breast, with no remarkable personal or family history.
Clinical discussion
Eosinophilic mastitis is an extremely rare benign pathology that may be mistaken for breast carcinoma. However, eosinophilic mastitis can be diagnosed using a combination of ultrasound imaging and fine needle aspiration or ultrasound guided biopsy or excisional biopsy. Histopathology examination is the key tool to a proper diagnosis.
Conclusion
Eosinophilic mastitis is an extremely rare benign pathology that affects the breast tissue presenting in the form of an ill-defined mass and may be mistaken for breast carcinoma.

Introduction and importance
The severity of a bee sting reaction can vary. There are two kinds of responses: local and systemic. The systemic manifestations are rare, especially polyserositis. Polyserositis describes the inflammation of serous membranes such as the pericardium, the pleura, or the peritoneum. We reported a case of polyserositis following a honeybee sting with late presentation.
Case presentation
This is a case report of a 30-year-old man who presented with progressive dyspnea, swelling of both lower limbs, and abdominal pain that began three days after the bite. CT showed pericardial, pleural, and abdominal fluid. Echocardiography showed tamponade. He underwent surgery to remove pericardial and pleural fluid. Following surgery, the patient underwent medical treatment. Ten days following treatment he developed a complete resolution of all symptoms and signs.
Clinical discussion
Bee stings can be life- threatening. Polyserositis occurring due to honey bee sting is a rare complication. The honey bee sting appeared to cause increased microvascular permeability. Pericardial, pleural effusion, abdominal ascites, and lower limb edema due to honey bee stings are infrequent complications. The physician should know enough about all the possible side effects of bee stings.
Conclusion
Physicians should be informed of the rare complications of bee stings. To prevent systemic complications medical treatment is recommended.

Introduction and importance
Oncocytic cysts are benign lesions seldom found in the region of the larynx. The phenomenon leading to their appearance is currently not well known but could be linked with aging and smoking. This article describes the case of a patient in whom a laryngeal oncocytic cyst was found.
Case presentation
A 52-year-old man presented during a screening for upper aerodigestive tract cancer with a lesion on the anterior third of the left vocal cord. He reported no symptoms but had tobacco use. Other medical history was unremarkable. Laryngoscopy revealed a cyst arising from the left vocal cord. It was excised with CO2 laser and measured 0,3 × 0,2 × 0,1 cm. Histopathology revealed that the cyst was composed of oncocytic cells lining the epithelium, with eosinophilic and granular aspect in the cytoplasm, with a small and dark nucleus. Thus far, there is no sign of recurrence with this patient.
Clinical discussion
Laryngeal oncocytic cysts are unusual lesions which can appear with different types of symptoms or with no symptoms. They are formed with oncocytes, with eosinophilic cytoplasm and dark nuclei. Oncocytic cysts have generally no recurrence, but follow-up care is required for mechanisms of such lesions are not well known. Metaplasia in this type of lesions would be caused by physiological exhaustion and inflammation.
Conclusion
A patient presented with an oncocytic cyst fortuitously discovered and underwent CO2 laser to remove it. The causes may have been smoking and aging, but it remains a rare and atypical case.

Trichinellosis is a zoonosis, caused by roundworms of the genus Trichinella. Domestic pigs, wild boars, bears, rodents and horses are reservoir animals. We report a case of neck trichinosis presenting as lateral neck swelling. The diagnosis of trichinosis was confirmed by the presence of larvae on muscle biopsy. Furthermore, lateral neck swelling may provide a diagnostic challenge by clinically mimicking a lymphoma or other causes of lateral neck swelling. Due to its rarity and its tendency to pose a clinical diagnostic challenge, we decided to report it.
Case presentation
A-10 yr old male patient presented with a 6 × 4 cm firm; non-tender left lateral neck swelling. Histopathology examination confirmed the diagnosis of trichinosis and the patient was started on albendazole 15 mg/kg/day, divided into two doses and prednisolone 20 mg by mouth, two times daily, for 14 days. Having completed his medication, he had a smooth course and was discharged with appointment scheduled for follow-up after 3 months.
Discussion
Trichinella spp. occur worldwide, most frequently in regions with temperate climates. About 10,000 human infections occur annually worldwide. Cultural factors such as traditional dishes based on raw or undercooked meat or meat-derived products play an important role in the epidemiology of the disease.
Conclusion
In the clinical evaluation of a patient with lateral neck swelling, trichinosis must be considered as a differential diagnosis in subjects from endemic areas for early diagnostic workup and management.

Metastatic liver tumors result from distant metastasis of a primary tumor. While chemotherapy is the treatment of choice, liver resection is aggressively performed for metastatic liver cancer derived from colorectal cancer. However, during chemotherapy, some disappearing liver metastases (DLMs) can be undetectable on computed tomography (CT), and surgical treatment remains challenging.
Presentation of case
A 48-year-old woman with abdominal pain and constipation was diagnosed with multiple liver metastases of colorectal cancer (CRLM) origin after a thorough examination involving CT and ethoxybenzyl-magnetic resonance imaging. Thirteen simultaneous CRLM were observed (largest metastasis diameter, 37 mm). Resection of the primary tumor (laparoscopy-assisted left colon resection + D3 dissection) was performed. Following eight courses of chemotherapy with mFOLFOX6 + panitumumab, only two CRLM and 11 DLMs were detectable on CT. With no new lesions identified, the patient underwent anterior segment resection and segment 3 and segment 7 partial hepatectomies. Contrast-enhanced intraoperative ultrasonography was performed, and all detectable lesions were resected. However, pathology results showed three CRLM in the anterior segment and no tumor cells in the segment 3 and segment 7 specimens. Postoperatively, the patient received eight courses of adjuvant chemotherapy with capecitabine and oxaliplatin (with capecitabine as a single agent beginning mid-course). The patient is currently alive and recurrence-free 3.5 years post-hepatic resection.
Discussion
The utility of EOB-MRI in the detection of DLMs has been demonstrated. The incidence of residual disease and subsequent early recurrence at sites diagnosed as DLMs on CT is reported to be approximately 80 %. Although aggressive resection of resectable DLMs is desirable to the extent that residual liver function can be preserved, recurrence is frequent and long-term careful follow-up is considered important.
Conclusion
Our patient, with multiple CRLM, responded to chemotherapy and underwent conversion surgery following resection of the primary tumor. Surgeons should consider possible surgical resection and DLM management when selecting the primary treatment.

Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms, initially described in the pleura but capable of arising in various anatomical locations, including the central nervous system. Dedifferentiation, characterized by the transformation of a low-grade tumor into a high-grade sarcoma, is an uncommon phenomenon in SFTs, especially in the intracranial region.
Case presentation
A 31-year-old male visited the neurology outpatient department with complaints of frequent headaches, seizures, speech difficulties, and weakness on the left side of his body. MRI was done which showed a relatively well defined T1 isointense and T2 hypointense extra-axial mass lesion in the right frontal lobe. Histopathological analysis confirmed the diagnosis of dedifferentiated SFT, marked by distinct fibroblastic differentiation and areas of high-grade sarcomatous transformation (rhabdomyosarcoma). Immunohistochemically, areas with fibroblastic differentiation showed strong and diffuse positivity for CD99, STAT6, vimentin and focal BCL-2 High-grade sarcomatous area was positive for vimentin, desmin and Myo-D1 and was negative for GFAP, EMA, PR, S-100, SMA and CD-34. It also showed focal positivity for STAT-6. The final diagnosis of intracranial solitary fibrous tumor with rhabdomyosarcomatous differentiation was made. At 2 months of follow-up, the patient is doing well.
Clinical discussion
Given the rarity of dedifferentiation in intracranial SFTs, there is limited consensus on optimal management strategies. En bloc resection remains the primary treatment approach, though the unpredictable behaviour of dedifferentiated SFTs complicates prognosis. This case underscores the importance of integrating clinical, radiological, and pathological findings for accurate diagnosis and discusses the need for further research into effective therapeutic options for dedifferentiated SFTs, particularly in challenging intracranial cases.
Conclusion
This case report presents a unique instance of an intracranial dedifferentiated SFT with rhabdomyosarcomatous dedifferentiation, highlighting the significant diagnostic challenges posed by this rare entity.
