Retroperitoneal and horseshoe ABSCESSes are particularly important because of the anatomic characteristics and the clinical differences between treatment approaches. There are several challenges in treating perirectal and retroperitoneal ABSCESS, the most important of which are partial recovery, high recurrence rates, and continence problems. A 65-yearold male patient underwent laparotomy at an external center with a diagnosis of ileus. Although no intraoperative pathology was detected, ileus persisted postoperatively, and the patient was referred to our clinic where he was diagnosed with a complicated horseshoe ABSCESS, 9 cm in diameter and displaying retroperitoneal extension. Perirectal ABSCESS drainage was performed, and the patient was discharged on the 5th day after the treatment. To the best of our knowledge, there have not been any previously reported cases of ileus caused by retroperitoneal ABSCESS as a complication of horseshoe ABSCESS. The case presented in this paper represents a RARE complication, thereby contributing to the literature which remains to be explored.

Acute pancreatitis is characterized by activation of digestive enzymes inside the pancreas. In severe pancreatitis, necrosis of pancreas and surrounding tissues may occur. Acute necrotizing pancreatitis commonly presents as pancreatic ABSCESS occasionally with systemic complications. RAREly, necrotic tissue may be drained from scrotum due to retroperitoneal extension of necrotic process. Here, we report a case of acute necrotizing pancreatitis in a 29-year-old man who presented with severe abdominal pain, nausea and vomiting. A computerized tomography (CT) scan confirmed necrotizing pancreatitis with multiple ABSCESSes spreading bilaterally in the pelvic cavity. Several surgical operations were performed, including necrosectomy and drainage. Subsequently, the patient developed a scrotal ABSCESS, which was drained surgically. The patient’ s condition was complicated by pleural effusion, acute respiratory distress syndrome, colocutaneous and scrotal fistulas, and incisional hernia. It seems that the scrotal ABSCESS is a very RARE complication of necrotizing pancreatitis.

Background: Brain ABSCESS is a serious infection within the cranial space characterized by an encapsulated accumulation of purulent exudates. This report presents a case of a 14-day-old neonate with a brain ABSCESS caused by Klebsiella pneumoniae.Case Report: The neonate, who had been treated with a traditional remedy involving bread dough and spices on the umbilical cord, presented with fever, poor feeding, and lethargy and later experienced seizures. Laboratory investigations confirmed the presence of K. pneumoniae in the blood and cerebrospinal fluid (CSF). Brain magnetic resonance imaging (MRI) demonstrated multiple ring-enhancing lesions in the bilateral frontal and left parietal regions, suggestive of brain ABSCESSes. After treatment, the patient’s condition improved, and he was referred to another equipped center for further treatment.Discussion: Previous cases were linked to idiopathic or maternal causes, such as urinary tract infections. There was no evidence that the causes of these ABSCESSes were community-acquired. This case, the first reported outside of India, may indicate a community-acquired brain ABSCESS.Conclusion: This case report highlights the need for awareness and appropriate management of brain ABSCESS caused by K. pneumoniae.

Infective endocarditis is a serious complication of intravenous (IV) drug abuse, with a reported mortality of 5 to 10%. A 21-year-old man, who was an intravenous drug abuser, presented with fever and dyspnea. Transthoracic echocardiography showed a highly mobile, large vegetation on the anterior leaflet of the tricuspid valve. Despite antibiotic therapy for ten days, the patient remained febrile. Transesophageal echocardiography revealed severe aortic regurgitation and an echo-lucent space between the tricuspid and aortic valves. Color Doppler demonstrated a flow within the echo-lucent space and a connection between that and the left ventricle, suggesting a perivalvular ABSCESS of the tricuspid valve opening in the left ventricle. The patient was transferred to the operating room, where he unfortunately expired.

Cataneous metastases from carcinoma of the larynx are very RARE. We observed a 75-year-old male patient with squamous cell carcinoma of the larynx who developed a subcutaneous nodule as an ABSCESS presentation in the buttock. It was found to be a metastatic squamous cell carcinoma of the laryngeal cancer, histopathologically. The skin manifestations proceeded laryngeal metastases by 18 months after laryngectomy and radical neck dissection. After three months, the patient died. Cutaneous metastasis of laryngeal carcinoma should be considered in all patients with previous laryngeal carcinoma represnting with cutaneous lesion.

Desmoid tumors (DTs) are slow-growing tumors with no malignant or metastatic features but are locally invasive. These tumors have an unpredictable but varied clinical course. Intra-abdominal sporadic DTs are very RARE and have a worse prognosis due to the mass effect on abdominal organs. This paper reports the diagnostic and surgical treatment of a 34-year-old man with DT of the small intestine without any genetic predisposing factor or history of trauma and abdominal surgery. The patient initially had mild pain in the periumbilical area and then presented with exacerbation of abdominal pain, acute abdominal symptoms, and peritonitis during elective diagnostic procedures. Abdominal CT scan with contrast injection showed a hypodense area with irregular borders and open-air foci of 171*160*85 mm in the middle of the abdomen and displacement of intestinal loops. Diagnostic and therapeutic laparotomy revealed a very large mass (18 cm in diameter) in the mesentery of a large part of the small intestine, a purulent ABSCESS adjacent to the mass, and perforation of the D4 part of the duodenum. Debulking resection of the tumor was performed due to the involvement of the upper mesenteric artery. Preoperative elective core needle biopsy, surgical biopsy, and immunohistochemistry reports revealed desmoid tumor. Desmoid tumor as a benign tumor can have aggressive manifestations similar to intra-abdominal malignancies.
