Loeys-Dietz syndrome (LDS) has been associated with multiple vascular abnormalities involving the entire arterial tree. However, limited reports regarding compromise in the aortoiliac and femoral bifurcation are available. Further, recommendations for optimal approach, thresholds for diameter at the time of surgery, and surveillance are also limited. We present a case of a 67-year-old male patient with LDS and aneurysmal aortoiliac and enlarging common femoral arteries aneurysms, who underwent open surgical repair. His past surgical history included multiple vascular interventions for lower extremity claudication and bilateral hip replacements. The right hip arthroplasty was previously removed due to infection. From the vascular standpoint, the patient underwent staged endovascular left hypogastric artery embolization and open aorto-bi-profunda bypass with a Rifampin-soaked Dacron graft. At 5-month follow-up, he remains asymptomatic with healed incisions and patent bypasses. This case highlights the challenges in managing peripheral aneurysms in LDS patients, emphasizing the need for tailored treatment strategies. While open repair is preferred, endovascular options may be considered in selected cases. Surveillance remains critical with annual cross-sectional imaging. Surgical planning is intricate due to comorbidities, anatomical complexities, and previous surgical infection. Surveillance of these patients must be strict as multiple vascular and non-vascular complications may arise. Therefore, collaborative decision-making is essential for optimal outcomes in this known high-risk population with connective tissue disorders.

Werner\'s syndrome is a rare progressive disorder that is characterized by a variety of clinical manifestations which mimic features of advanced ageing. Malignancy is one of the most problematic complications of Werner\'s syndrome. Lung cancer associated with Werner\'s syndrome is rare. A 54-year-old woman with Werner\'s syndrome was referred to our department because an abnormal shadow had been detected on routine chest radiography. Chest computed tomography revealed an abnormal nodule in the left upper lobe. Bronchoscopic examination revealed the presence of squamous cell carcinoma. Other imaging studies showed no metastatic lesions; therefore, the patient was diagnosed with stage IA3 squamous cell carcinoma. She underwent left upper lobectomy and lymph node dissection without major complications, and no recurrence was found for 2 years postoperatively.

Castleman disease (CD), also known as giant lymph node hyperplasia or angiofollicular lymph node hyperplasia, is a rare and indeterminate group of chronic lymphoproliferative disorders. CD is highly heterogeneous, classified into unicentric Castleman disease (UCD) and multicentric Castleman disease (MCD) based on lesion distribution, and further categorized into three pathological types: hyaline vascular type (HV), plasma cell type (PC), and mixed type (Mix). This paper describes a rare case of solitary mediastinal Castleman disease with transparent vessels in the anterior sacrum, presenting as the HV type. Surgical excision of the mass was performed following coccygectomy for treatment. The patient recovered well postoperatively. During a 6-month follow-up period, there were no signs of recurrence, and the patient\'s quality of life significantly improved.

A 40-year-old male patient was admitted due to abdominal distension and discomfort in the upper abdomen persisting for three days. Enhanced CT of the upper abdomen revealed an irregularly dense soft tissue area in the body and tail of the pancreas, approximately 7.6 × 3.1 cm in size, with blurred boundaries, and indistinct separation from the splenic artery and vein. Multiple liver lesions of varying sizes and slightly lower densities were also observed. Liver tumor biopsy considering a neuroendocrine tumor G2, combined with the medical history, led to a diagnosis of pancreatic neuroendocrine tumor G2 with liver metastasis. Physical examination showed mild tenderness in the upper abdomen but no other significant positive signs. During treatment, the patient developed multiple red papular rashes around the mouth, on both lower limbs, and the perineum, accompanied by itching. The glucagon level was 1138.3 pg/L. The patient underwent resection of the pancreatic body and tail, splenectomy, partial liver tumor resection, and cholecystectomy. Within five days post-surgery, the skin lesions began to crust and flake off. On the 14th day post-surgery, the serum glucagon level was rechecked at 136.4 pg/L. As of April 2024, progression of liver lesions was noted, with no significant skin symptoms during the period.

BACKGROUND: An ependymoma is a glial tumor that usually occurs in or near the ventricle, close to the ependyma. It rarely occurs exclusively in the brain parenchyma without being associated with the ventricle.
METHODS: Here, we report a rare case of a cerebellar ependymoma completely located in the brain parenchyma. A previously healthy 32-year-old female with a 1-month history of dizziness was admitted to our hospital. During hospitalization, magnetic resonance imaging of the brain revealed a space-occupying lesion measuring 57 mm × 41 mm × 51 mm in the right cerebellar hemisphere and inferior cerebellar vermis. The patient underwent surgical resection for the right cerebellar mass. Postoperative pathological examination revealed an ependymoma. At 1 year follow-up, the patient was doing well and showed no recurrence.
CONCLUSIONS: We conducted a literature review and summarized three theories regarding ependymomas located exclusively in the brain parenchyma, which are key to the diagnosis of intraparenchymal cerebellar ependymomas. Surgery and postoperative radiotherapy are the primary treatment options for ependymomas.

Calcifying odontogenic cyst, also known as Gorlin cyst is a rare benign cystic lesion primarily found in the jawbones, accounting less than 1% of odontogenic cysts. It can be associated with odontogenic tumors such as odontomas. We report a rare case of COC associated with complex odontoma in a young patient and discuss its clinical features, diagnosis, and treatment options. An 18-year-old female patient presented with a painless radiopaque lesion of the right mandibular bone at Oral Medicine and Oral Surgery department. Radiographs revealed irregular tooth-like structures in the canine-premolar area. The lesion was surgically removed, and histopathology confirmed COC with a complex odontoma. As of the World Health Organization\'s 2022 definition, COC is a developmental odontogenic cyst characterized by calcified ghost cells. It typically affects individuals during their second and third decades of life, with no gender preference, almost equally in the maxilla and the mandible. The main treatment is total enucleation, with a generally favorable prognosis. Histopathology is essential for diagnosis due to its mimicry of other jaw conditions. Long-term follow-up is needed to prevent recurrences.

Cameroon is a low-and-middle income country (LMIC) with one of the highest incidence and mortality from cervical cancer in Africa. In this Central African country where the prevalence of human immunodeficiency virus (HIV) is high and the screening coverage is low, cervical cancer is the most deadly and the second most common cancer among women. Notwithstanding the growing burden of cervical cancer in Cameroon, most patients - often of lower socioeconomic status - continue to encounter multi-level barriers to timely and adequate care. These include the lack of physical and financial access to healthcare facilities, limited quality pathology, imaging and treatment services, ignorance of disease by the population, shortage of a well-trained oncology workfroce, which result in significant delays in gaining access to screening, diagnosis, treatment and care. This paper presents 3 cases of patients with advanced cervical cancer who had surgery (hysterectomy) as primary treatment, without appropriate post-surgical investigation to further specify disease stage, persistence of residual disease, and need for adjuvant chemoradiation. Pathology services and diagnostic imaging procedures remain scarce and underused in LMIC countries like Cameroon. Healthcare professionals involved in patient care lack adequate knowledge, skills and collaborative strategy to properly navigate these patients. To address these challenges, the health system should be reinforced with adequate infrastructures, sustainable funding should be secured to enhance universal health coverage and promote cancer prevention and control programs, multidisciplinary teams and coordination of care among providers should be improved, and relevant health indicators should be put in place to better monitor the quality of care delivered to patients who are mostly vulnerable and uninformed.

Present case report describes a case of an atypical oesophageal actinobacillosis in an adult cow presented to the university hospital with a history of inability to drink and swallow. Clinical examination revealed a five-inch swelling in the jugular groove. Skiagram revealed the presence of a small and slightly radio opaque round growth. Exploratory surgical excision of the growth was adapted as palliative treatment and the extirpated tissue was fixed in 10% buffered formalin. Histopathological examination revealed pyogranulomatous inflammation with radiating eosinophilic club shaped bodies surrounding small colonies of coccobacilli. Gram and Ziehl-Neelsen stains confirmed the presence of Gram-negative and non-acid-fast coccobacilli. Histopathology confirmed the pathognomonic lesion and proved to be a modality of choice for pathologists to reach at a diagnosis of atypical oesophageal actinobacillosis in a cow. After the exhaustive search of relevant literature on atypical actinobacillosis, the authors claim this to be the second report of oesophageal actinobacillosis worldwide.

BACKGROUND: Colo-colonic intussusception (CI) in adults is rare, usually caused by malignant conditions. Nonmalignant tumors, like colonic lipomas (CLs), can also be an underlying cause.
METHODS: We report an unusual case of a 62-year-old man admitted to the emergency department with acute abdominal symptoms. The CT scan confirmed the colonic obstruction, causing significant distention in the transverse and right colon. It also revealed an intraluminal pedunculated colonic mass with fatty density. Peroperatively, a descending colon intussusception was noted. We performed a left colon resection with a double colostomy on the left flank. The postoperative follow-up was uneventful. Pathologic examination of the surgical specimen revealed two lipomas. One of them was pedunculated and protruded into the colonic lumen causing the intussusception.
CONCLUSIONS: We conducted a literature review of adult CLs complicated by CI, covering the period from January 1900 to June 2024, including 203 cases. We excluded lipomas exclusive to the small intestine and ileocecal valvula. Our analysis focused on the clinical and pathological characteristics of these cases, as well as the available management options.
CONCLUSIONS: Colonic intussusception due to lipomas are uncommon with a challenging preoperative diagnosis despite the evolution of imaging procedures. We aimed by our case to highlight such pathology and to study its features and the possibilities of its management.

UNASSIGNED: Frontal bone osteomyelitis associated with a subperiosteal abscess is known as Pott\'s puffy tumor. Pott puffy tumor (PPT) is a rare entity that mainly affects children and adolescents. It is less common in adults, accounting for 30 % of cases, and predominates in men. The therapeutic management of Pott\'s puffy tumor is an emergency and is based on a combination of antibiotic therapy and surgical treatment to prevent the emergence of intracranial complications and reduce morbidity and mortality.
METHODS: We report the case of a 29-year-old female patient, who consulted our ENT (ear, nose, and throat) department for a post-traumatic periorbital swelling. CT scan confirmed osteomyelitis of the frontal bone and subperiosteal abscess. The patient underwent a combined surgical drainage with antibiotics. The aim is to describe an effective management of this clinical case.
UNASSIGNED: This condition presents as a subperiosteal/subgaleal abscess creating a frontal swelling, with osteomyelitis of the frontal bone most often secondary to frontal sinusitis. The most feared complications are intracranial, which can be life-threatening. Imaging is the key to positive diagnosis, as the evolution and prognosis of TPP depend on rapid management. A CT scan of the head is the examination of choice to confirm the diagnosis. Antibiotic therapy should be started as soon as possible, it is usually administered by intravenous injection. Surgical management may be limited to percutaneous drainage by needle or transnasal endoscopy or trephination, sometimes including trimming of the subperiosteal/subgaleal abscess. In the case of intracranial complications, a craniotomy may be necessary.
CONCLUSIONS: The Pott\'s puffy tumor is little-known complication, usually secondary to untreated or poorly treated sinusitis. As a result of this poor understanding, the condition can lead to complications, especially intracranial ones, which increase morbidity and mortality.
