A 14-year-old boy was admitted to the hospital due to a single episode of afebrile seizure and four hours of impaired consciousness. Three months prior to admission, he had a history of bilateral uveitis. Cerebrospinal fluid analysis revealed a mild elevation in white blood cell count. Cranial magnetic resonance imaging and contrast-enhanced scans showed multiple abnormal signals in both cerebral hemispheres, with punctate and nodular enhancement. Susceptibility-weighted imaging revealed multiple punctate hemorrhages within lesions in the bilateral frontal and left parietal lobes, suggestive of vasculitis. Brain biopsy demonstrated inflammatory granulomatous lesions. No secondary causes were identified, and the final diagnosis was granulomatous primary central nervous system vasculitis. The patient's condition improved after treatment with methylprednisolone sodium succinate and mycophenolate mofetil. This report describes a rare case of granulomatous central nervous system vasculitis in a child and provides valuable insights for the diagnosis and treatment of this disease.

Objective:This article explores the diagnosis and treatment of a special type of laryngeal foreign body with granuloma in children, providing a clinical reference for standardized diagnosis and treatment. Methods:This article retrospectively analyzes one case admitted to our department and five other cases reported in relevant literature involving a special type of laryngeal foreign body with granuloma in children. It summarizes the clinical characteristics of this disease and explores its diagnosis and treatment. Results:①A total of 6 cases were misdiagnosed and had a long course of illness. Five cases had no clear history of foreign body at the first visit. One case had foreign body history but no foreign body was found. ②The clinical symptoms were diverse, which could be hoarseness, cough, wheezing, dyspnea, or no symptoms. ③A total of 3 cases were diagnosed by laryngoscopy, and 3 cases were diagnosed by laryngoscopy and imaging examination. ④Foreign bodies that were not wrapped in granulomas, were removed first and then the granulomas were treated; foreign bodies wrapped in granulomas were removed after the removal of granulomas. Conclusion:A special type of laryngeal foreign body with granuloma may lack of accurate foreign body history, resulting in long-term retention of foreign bodies, leading to granuloma formation and misdiagnosis. Electronic laryngoscopy combined with CT examination contribute to early diagnosis. Low temperature plasma under endoscope and anesthetic laryngoscope is conducive to the exposure and precise removal of foreign bodies and avoids tracheotomy to a certain extent.

Objective:This study aims to explore the clinical effectiveness of a novel treatment method for refractory laryngeal contact granuloma, involving CO2 laser excision with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. Methods:A retrospective analysis was conducted on 18 patients with refractory laryngeal contact granuloma who visited Department of Otolaryngology Head and Neck Surgery, Nanjing Tongren Hospital, School of Medicine, Southeast University from January 2021 to June 2023. These patients underwent CO2 laser excision of the granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. During follow-up, electronic laryngoscopy were performed at 1, 3, 6, and 12 months postoperatively, and local laryngeal mucosa, voice quality, and pharyngeal discomfort symptoms were evaluated. Results:Postoperative electronic laryngoscopy revealed the disappearance of granulomas in all 18 patients. Symptoms such as hoarseness, foreign body sensation in the throat, and cough were significantly improved. No complications were observed systemically or locally. No recurrence was observed during one-year follow-up. Conclusion:CO2 laser excision of granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection could eliminate the lesion, restore the integrity of the vocal fold lining, preserve the perichondrium, and provide a time window for mucosal flap recovery. This approach adheres to the principle of preserving normal mucosa, achieves a high cure rate, and is therefore worthy of widespread promotion and application in clinical practice.

Syphilis is one of the most common sexually transmitted diseases in the world. It is known as “the great mimicker” due to its varied cutaneous presentations, which can make it challenging to diagnose. We report a case of a 20‑year‑old female presenting with a nonhealing, pruritic, annular plaque on the left malar area of 3‑month duration. She was initially treated as a case of tinea faciei. The lesion was unresponsive to topical antifungals and steroids with continued increase in size and number. Skin biopsy revealed secondary syphilis with histopathologic features of granuloma annulare. Degenerated collagen, not a feature of secondary syphilis, was seen, prompting further studies to confirm the diagnosis of secondary syphilis. Alcian blue stain was negative, which helped rule out granuloma annulare. She was then given benzathine penicillin G 2.4 million U, which led to a significant decrease in the size of the lesion noted 1 week posttreatment. Only postinflammatory hyperpigmentation was noted after 1 month of treatment. Clinically, secondary syphilis may present as an annular lesion that can mimic tinea. This can also present with atypical histopathologic features and an in‑depth investigation is needed to further confirm the diagnosis.

Inflammatory myofibroblastic tumor is a rare tumor of mesenchymal origin. A case of intratracheal inflammatory myofibroblastic tumor in a male child was reported. The clinical characteristics, diagnosis, treatment and prognosis of the disease were reviewed based on the literature, and a differential diagnosis between inflammatory myofibroblastic tumor and hamartoma was performed to ultimately confirm the nature of the tumor in the child.

Inflammatory myofibroblastic tumor （IMT） is a rare mesenchymal soft tissue tumor characterized by borderline or low-grade malignancy. It is rare childhood tumor with an average age of onset of 10 years old. It is even rarer in infants and toddlers, and the etiology and pathogenesis of this tumor are still unclear. The clinical presentation of IMT is non-specific and are related to the location of the tumor. When the tumor compresses adjacent organs, it can cause pain and functional impairment. According to the current literature, IMT is most commonly found in the digestive and respiratory systems, but also occasionally occur in the genitourinary system, head and neck, and limbs. At present, there have been no reports of nasopharyngeal IMT involving nasal cavity of infants and toddlers at home and abroad.This article reports a case of a massive inflammatory myofibroblastic tumor involving the nasal cavity and nasopharynx in an infant. Plasma-assisted minimally invasive surgery was performed through multiple surgical approaches and achieved satisfactory therapeutic results. This case report may provide valuable reference for the treatment of similar diseases.

Epstein-Barr virus (EBV), a double-stranded DNA virus with an envelope, is a ubiquitous pathogen that is prevalent in humans, although most people who contract it do not develop symptoms (Kerr, 2019). While the primary cells EBV attacks are epithelial cells and B lymphocytes, its target range expands to a variety of cell types in immunodeficient hosts. Serological change occurs in 90% of infected patients. Therefore, immunoglobulin M (IgM) and IgG, serologically reactive to viral capsid antigens, are reliable biomarkers for the detection of acute and chronic EBV infections (Cohen, 2000). Symptoms of EBV infection vary according to age and immune status. Young patients with primary infection may present with infectious mononucleosis; there is a typical triad of symptoms including fever, angina, and lymphadenectasis (Houen and Trier, 2021). In immunocompromised patients, response after EBV infection may be atypical, with unexplained fever. The nucleic acid of EBV can be detected to confirm whether high-risk patients are infected (Smets et al., 2000). EBV is also associated with the occurrence of certain tumors (such as lymphoma and nasopharyngeal carcinoma) because it transforms host cells (Shannon-Lowe et al., 2017; Tsao et al., 2017).
