Key Clinical Message: Pauci‐immune necrotizing glomerulonephritis (PING) is a small vessel renal vasculitis usually associated with the presence of antineutrophil cytoplasmic antibodies (ANCA) against myeloperoxidase or proteinase. A small proportion of PING patients do not have ANCA antibodies. A condition known as Pauci‐immune necrotizing glomerulonephritis, or PING for short, is a type of kidney inflammation that affects small blood vessels. This condition is typically linked with the existence of certain antibodies, specifically antineutrophil cytoplasmic antibodies or ANCA, which target myeloperoxidase or proteinase. However, it's worth noting that a minor percentage of individuals diagnosed with PING do not possess these ANCA antibodies. A 24‐year‐old woman with no previous medical history arrived at the ER due to various symptoms including joint pain, fever, difficulty swallowing, and shortness of breath. Despite multiple symptoms suggesting systemic lupus erythematosus (SLE), this diagnosis was ruled out based on the EULAR/ACR 2019 classification criteria and laboratory tests. Other potential diagnoses such as rheumatoid arthritis (RA) and eosinophilic garnulomatosis with polyaniitis (EGPA) were also excluded based on respective criteria. The patient was treated with a 3‐day course of methylprednisolone, followed by prednisolone, which improved her creatinine levels. Subsequent tests for P‐ANCA and C‐ANCA were negative. A kidney biopsy confirmed necrotizing glomerulonephritis, consistent with pauci‐immune vasculitis. A bronchoscopy revealed bleeding and hemorrhage in her lungs, but bacterial culture analysis was negative. The patient was given piperacillin, tazobactam, and vancomycin for septic coverage, as well as intravenous immunoglobulin (IVIg), which led to symptom improvement. [ABSTRACT FROM AUTHOR]

Key Clinical Message: In the context of lymphoma, it is of paramount importance to perform subsequent Positron Emission Tomography‐Computed Tomography (PET‐CT) scans to ensure the comprehensive eradication of neoplasms. Primary renal diffuse tumors constitute less than 1% of all renal neoplasms. Among these, diffuse renal large B‐cell lymphoma is an exceedingly rare extranodal lymphoma. A 64‐year‐old male presented to the Department of Urology with complaints of persistent left flank discomfort for a duration of 2 weeks. Additionally, he reported generalized weakness, fatigue, and symptoms indicative of lower urinary tract obstruction, such as discomfort in the left testicle and dysuria. Ultrasound imaging revealed an echogenic structure with thickened, reactive walls and a turbid fluid core, located in the left flank, proximal to the lower pole of the kidney. This structure was subsequently identified as diffuse renal large B‐cell lymphoma. For the diagnosis of large B‐cell lymphomas, it is imperative that a proficient hematopathologist performs a comprehensive examination of the tumor tissue, preferably utilizing an excisional biopsy. The categorization of lymphoma requires specialized tests such as immunohistochemistry, flow cytometry, fluorescence in situ hybridization (FISH), and molecular testing. In instances where a renal mass is detected, healthcare professionals should consider performing a biopsy. In lymphoma cases, follow‐up Positron Emission Tomography‐Computed Tomography (PET‐CT) scans are crucial to confirm the complete eradication of the tumor. [ABSTRACT FROM AUTHOR]

Key Clinical Message: The importance of urologists and pathologists being knowledgable about primary testicular hemangiomas and other benign adult testicular neoplasms, though rare, is crucial. Ensuring these professionals are well‐versed in these conditions is vital in medicine. Testicular sparing surgery, especially when tumor markers are negative, is a common approach for patients with small or uncertain testicular masses. The cause of the uncommon benign testicular tumor known as testicular capillary hemangioma is currently unclear. Children are shown to have a greater incidence than adults. Histopathological examination reveals a vascular tumor with a well‐formed capillary lumina. The lesions are bordered by flattened endothelium and have lobulated clusters of closely spaced capillaries with an abundance of vascular gaps. These capillaries have anaplastic characteristics and lack mitotic activity. The patient, who was 24‐year‐old, came to the urology department complaining of severe testicular pain. He had no significant medical history. Clinical examination found a mass at the upper pole of the testicle. An ultrasonography Doppler study found a left varicocele that measured 3.5 mm in diameter, as well as a mass at the upper part of the left testicle. Pathologic examination confirmed the presence of a benign hemangioma with. Although rare, it is important for urologists and pathologists to be aware of primary testicular hemangiomas and other benign adult testicular neoplasms. Testicular sparing surgery has always been considered in patients with small or indeterminate testicular masses with negative tumor markers. [ABSTRACT FROM AUTHOR]

Introduction and Importance: Kimura's disease (KD) is a chronic, nonmalignant inflammatory disorder that primarily affects subcutaneous tissue. It is typically characterized by painless nodules in the head and neck regions, accompanied by elevated eosinophil and serum IgE levels. The purpose of this case study is to elucidate this rare disease, particularly in the Asian region and Syria, and to explore diagnostic and therapeutic methodologies with the objective of mitigating the number of undiagnosed patients suffering from this disease., Case Presentation: A 23-year-old male patient presented to the Ear, Nose, and Throat (ENT) Department of the hospital with symptoms that had been initiated 7 months prior. The primary symptoms were pain and swelling in the left preauricular area, followed by subsequent swelling in the right preauricular area the next day. The patient experienced severe, intermittent pain, generalized pruritus, and systemic manifestations, including fever, chills, fatigue, malaise, anorexia, and a weight loss of 20 kg over the course of seven months. A fine-needle aspiration of the left parotid gland revealed the presence of lymphocytes at various maturation stages, with no evidence of abnormal cells. A diagnosis of KD was subsequently confirmed., Clinical Discussion: To our knowledge, this case represents the second documented instance of KD in Syria. Furthermore, our case is among the extremely rare instances of KD in a patient without a history of renal transplantation., Conclusion: Further research is essential to ascertain the actual prevalence of this condition and to identify the most effective management strategies., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 The Author(s).

Introduction: Univentricular heart disease is a relatively rare condition that affects infants, with a prevalence ranging from 0.05 to 0.1 per 1000 live births. It is characterized by an abnormality in the structure of the heart, specifically the presence of only one main pumping chamber (ventricle) instead of the usual two., Presentation of Case: In this particular case, a newborn male was diagnosed with double-inlet left ventricle (DILV), a specific form of univentricular heart disease. Following his birth, he exhibited symptoms of central cyanosis (a bluish tint to the skin due to poor oxygenation) and difficulties with breastfeeding. Clinical evaluation, along with a heart ultrasound, confirmed the need for palliative surgery. At the age of 6 months, the patient is scheduled to undergo the Glenn procedure, a surgical intervention that aims to redirect blood flow to the lungs and improve oxygenation., Clinical Discussion: Given the complexity of double-inlet single ventricle anomalies, there are multiple differential diagnoses that need to be considered for accurate diagnosis, including conditions such as tricuspid atresia, large ventricular septal defect and corrected transposition of the great arteries with ventricular septal defect., Conclusion: Early intervention in the immediate postnatal period plays a crucial role in improving survival rates and reducing long-term complications. It is, therefore, essential to continue researching and refining treatment approaches., Competing Interests: No conflict of interest.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2024 The Author(s).
