Respiratory papilloma is a relatively common benign tumor of the respiratory tract, and a few patients may develop malignant changes. The disease has an insidious onset and lacks specific clinical manifestations, and its manifestations are closely related to the growth mode, location and size of the tumor. It can involve multiple parts, such as the larynx, trachea, bronchus, and lung parenchyma, which cause coughing, hoarseness, dysphonia, and, in severe cases, may lead to obstruction of the respiratory tract. At present, the treatment of respiratory papilloma lacks standardization, and there is no effective method to cure the disease. Surgery remains the main treatment for alleviating patients\' symptoms and preventing airway obstruction. However, due to the high recurrence rate of respiratory papilloma, multiple surgeries are often needed, which reduces the quality of life of patients and increases their disease burden and economic burden. Bevacizumab, a vascular endothelial growth factor-binding antibody inhibitor, is a promising adjuvant treatment modality that shows good potential for reducing symptoms and the frequency of surgery. This article aimed to review the efficacy and safety of bevacizumab for the treatment of respiratory papilloma and discuss the differences and efficacy of the systemic application and intralesional injection of bevacizumab for the treatment of respiratory papilloma.
呼吸道乳头状瘤是呼吸道较常见的良性肿瘤，少数可发生恶变。该病起病隐匿，缺乏特异性临床表现，其表现与肿瘤生长方式、部位、大小密切相关，可有喉、气管、支气管、肺实质等多个部位受累，引起咳嗽、声音嘶哑、发音困难，严重者可致呼吸道梗阻。目前，呼吸道乳头状瘤的治疗缺乏规范统一的标准，且尚无治愈该病的有效方法，手术是减轻患者症状、预防气道梗阻的主要治疗方式。然而呼吸道乳头状瘤复发率高，患者往往需要经历多次手术治疗，频繁的手术降低患者的生活质量，增加患者的疾病负担与经济负担。贝伐珠单抗作为血管内皮生长因子结合抗体抑制剂，是一种有希望的辅助治疗方式，在减轻症状、减少手术频率方面表现出较好的潜力。本文主要对贝伐珠单抗治疗呼吸道乳头状瘤的有效性及安全性进行综述，并探讨全身性应用和病灶内注射贝伐珠单抗治疗呼吸道乳头状瘤的差异及疗效。.

Squamous papilloma is a benign neoplasm that originates from the stratified squamous epithelium of the mucous membrane. Its principal etiological factor is human papillomavirus infection, with a predilection for manifesting within the oral cavity. Squamous papilloma predominantly affects regions on the palate, cheeks, lips and tongue. However, to the best of our knowledge, the occurrence of squamous papilloma within the confines of the mandible remains unreported hitherto. The present report documents a case of squamous papilloma involving the mandible who was managed at the First Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) in January 2023. The patient underwent a series of recurrent jaw inflammations, manifesting with malignant imaging characteristics. Subsequent pathological analysis confirmed a diagnosis of papilloma in the jaw. The present report highlights the pivotal role of prolonged inflammation in the genesis of jaw squamous papilloma, prompting avenues for further investigation, including the potential of inflammation to induce aberrant cell growth, mediate cell interactions, orchestrate cytokine actions and influence stress mediators. In addition, the current study posits a plausible connection between persistent inflammation, compromised epithelial integrity and an increased likelihood of head and neck papilloma, particularly concerning human papillomavirus infection. This article delineates the clinical attributes of the uncommon manifestations of jaw papilloma and delves into the associated mechanisms, thereby contributing to an enhanced comprehension of jaw disorders. This comprehensive insight equips clinicians with a heightened knowledge base for more precise diagnosis and treatment of analogous cases.

BACKGROUND: With advancements in medicine and economy, it would be expected that there will be changes in the clinical characteristics of upper respiratory papillomatosis. The aim of this study was to examine the current clinical characteristics of upper respiratory papillomatosis, as there are no recent data in the literature.
METHODS: The medical records of 1894 patients with upper respiratory papillomatosis were retrospectively reviewed. Data extracted included clinical features, laryngoscopy images, and surgical procedure data.
RESULTS: The upper frequency of upper respiratory papillomatosis in the oropharynx was 69.1 %, and in the larynx was held 28.9 %. The overall postoperative relapse rate was 2.4 %. The relapse rate of laryngeal papillomatosis was 6.5 %. Approximately 2.6 % of cases were in children. All postoperative recurrences in children were laryngeal, and the recurrence rate was 30.4 %.
CONCLUSIONS: The oropharynx has the highest frequency of upper respiratory papillomatosis. The larynx, however, has the highest rate of postoperative recurrence. Compared to adults, children are more likely to experience a postoperative recurrence.

UNASSIGNED: Bladder papilloma, a rare benign tumor of the urinary tract, accounts for 1-4 % of bladder tumors. Its distinct features, diagnosed through light microscopy, include architectural and cytological characteristics. Despite its rarity, bladder papilloma is clinically significant due to its distinct traits, low recurrence risk, and potential progression to other urothelial neoplasms. Understanding this condition is crucial for early diagnosis and optimal patient care.
METHODS: A 66-year-old male with benign prostatic hyperplasia presented with one month of intermittent hematuria. Physical examination and laboratory tests were unremarkable. Imaging revealed an 11 × 10 × 7 mm echogenic nodular lesion with calcifications on the right bladder wall. Cystoscopy identified a polypoid lesion, leading to transurethral resection. Histopathological examination confirmed bladder papilloma without malignant features.
UNASSIGNED: Bladder papilloma typically presents with hematuria, mainly in younger patients, with low recurrence and rare progression to aggressive cancers. Diagnosis involves endoscopy and resection, followed by cystoscopic surveillance. Understanding its classification, characteristics, and risk factors aids in accurate management.
CONCLUSIONS: Bladder papilloma diagnosis relies on light microscopy, with hematuria as a primary symptom, often in younger patients. Recurrence risk is low, and progression to aggressive cancers is rare. Diagnosis involves endoscopy, resection, and cystoscopic follow-up. This case enhances our understanding of bladder papilloma, contributing to improved care.

The literature review presents current data on the epidemiology, drug, and surgical treatment of laryngeal papillomatosis in adults. Possible prospects for further study of the prevalence and incidence of the disease and provoking factors of recurrence of the disease for the development of possible preventive measures are considered.

In this study, we compared the effectiveness of various methods used in the treatment of cattle with cutaneous papillomatosis. Ivermectin, Tarantula cubensis extract, levamisole, autovaccine, and a combination of T. cubensis extract + levamisole were administered to the animals. The animals were divided into six equal groups. Animals in the control group (n = 10) did not receive any treatment. The animals in the experimental group were administered Ivermectin [three times a week, n = 10, subcutaneous, (SC)], Tarantula cubensis extract (twice a week, n = 10, SC), autologous vaccine (three times at 10-day intervals, n = 10, SC), levamisole [twice at one-week intervals, n = 10, intramuscular (IM)], and levamisole + Tarantula cubensis extract (concurrently). All animals used in the study were monitored for three months at an interval of 15 days. No regression was detected in the papillomas of the control group animals, but recovery was recorded in animals treated with ivermectin at a rate of 70% (7/10), while it was 60% (6/10) in those treated with T. cubensis extract, 100% (10/10) in those treated with autovaccine, 50% (5/10) in those treated with levamisole, and 90% (9/10) in those treated with the combination of T. cubensis extract + levamisole. Significant differences were found between the control group and all treatment groups. Recovery mostly occurred within 45-60 days (P < 0.05). The five treatment modalities applied for the treatment of bovine cutaneous papillomatosis were statistically evaluated and all methods of treatment were effective at different rates. The most precise and effective treatment method was the autovaccine one.

A papilloma is a benign tumor arising from an epithelial surface. Mostly a papilloma appears as an asymptomatic intraoral lesion and is often associated with the human papilloma virus (HPV). In this case report two similar, verrucous papules, sessile bilateral on the back of the tongue, were surgically removed in a 65-year-old male patient. Thereby two different methods of treatment were compared. On the right side of the back of the tongue, excision by scalpel, as the gold standard treatment modality, was performed. On the left side a surgical removal by a CO2 laser was performed. In a photothermal procedure, without direct contact to the tissue, the laser beam is cutting through the mucosa. Secondary wound healing can take place. Both methods were compared in relation to their application, wound healing, quality of the biopsy and morbidity. Postoperative less discomfort and a slightly faster wound healing could be seen after scalpel removal. The histopathological examination was comparable for both methods.

Squamous papilloma of the oral cavity is frequently seen in adult patients and is typically presented as painless exophytic granular or cauliflower-like lesions over the tongue, floor of the mouth, palate, uvula, lips, and faucial pillars. Most of the lesions are solitary and grow rapidly to about 0.5 cm. Oral squamous papilloma has no known malignant potential, with conservative surgical excision being the treatment of choice. Recurrence is rare. It occasionally causes symptoms, unless the presentation is atypical, as in our case. An elongated uvula can cause discomfort and reduce a patient\'s quality of life. This study aims to report an atypical presentation of a squamous papilloma over the soft palate.
