    背景:局灶性结节增生是一种常见的非恶性肝脏肿块。这种非血管病变在儿童中并不常见,尤其是那些没有诱发因素的人,即辐射,化疗,和造血干细胞治疗.病变的外生性生长超过肝脏边缘并不常见,并且可能使病变的诊断复杂化。本报告观察到健康儿童的局灶性结节增生是带蒂病变。
    方法:我们描述了一个9岁健康的波斯儿童,他在体外受精后出生,抱怨腹痛持续数月和心悸。采用超声波和计算机断层扫描,在右上象限检测到与局灶性结节增生成像特征相符的肿块.孩子接受了手术,肿块被切除。
    结论:诊断局灶性结节增生,尤其是有花梗的形式可能具有挑战性,尽管闪烁扫描的磁共振成像几乎100%敏感和特异性。因此,在某些情况下,可能需要进行活检以排除恶性肿瘤。可疑肿块患者的确定性治疗,连续检查中病变的显着增长,和持续的症状,如疼痛,是切除,可以开腹或腹腔镜。
    BACKGROUND: Focal nodular hyperplasia is a common nonmalignant liver mass. This nonvascular lesion is an uncommon mass in children, especially those with no predisposing factors, namely radiation, chemotherapy, and hematopoietic stem cell therapy. Exophytic growth of the lesion further than the liver margins is not common and can complicate the diagnosis of the lesion. This report observes a focal nodular hyperplasia as a pedunculated lesion in a healthy child.
    METHODS: We describe a 9-year-old healthy Persian child who was born following in vitro fertilization complaining of abdominal pain lasting for months and palpitation. Employing ultrasound and computed tomography, a mass was detected in the right upper quadrant compatible with focal nodular hyperplasia imaging features. The child underwent surgery and the mass was resected.
    CONCLUSIONS: Diagnosing focal nodular hyperplasia, especially pedunculated form can be challenging, although magnetic resonance imaging with scintigraphy is nearly 100% sensitive and specific. Thus, a biopsy may be needed to rule out malignancies in some cases. Deterministic treatment in patients with suspicious mass, remarkable growth of lesion in serial examination, and persistent symptoms, such as pain, is resection, which can be done open or laparoscopic.

    结膜乳头状瘤通常发生在婴儿和儿童中。据信病原体,人乳头瘤病毒(HPV),在分娩时从受感染的产妇产道植入新出生的结膜囊。它生长为单生或多个有花梗的良性肿块,与节状相邻。这是不常见的,但如果在成人中生长,它会在结膜角膜缘生长,可能是恶性的。
    一名美国黑人成年男性在其左下眼睑出现两种明显的结膜生长。一个生长被花梗,第二个生长被固着。最初诊断为“良性结膜乳头状瘤”。建议患者等待观察。大约两年后,肿瘤的大小增加了一倍。出于诊断和治疗原因,进行了手术切除活检。使用液氮并应用双冻融技术对瘤床进行术中冷冻治疗。组织病理学证明肿块是良性的,由HPV引起。手术切除期间病毒的复发和播种导致多个新肿块是结膜乳头状瘤治疗期间的可怕并发症。尽管是短暂的后续行动,然而三个月后没有复发的迹象.
    对文献的简要回顾强调了这样一个事实,即很少有结膜乳头状瘤可以在不寻常的部位和成人中发展。我们认为,这种病例的罕见人口统计学和解剖学表现值得与眼科社区分享。
    UNASSIGNED: Conjunctival papilloma commonly develops in infants and children. It is believed that the etiologic agent, human papillomavirus (HPV), gets implanted from the infected maternal birth canal in the conjunctival sac of the new borne while parturition. It grows as solitary or multiple pedunculated benign masses adjacent to the caruncle. It is uncommon but if growing in adults it grows on the limbal conjunctiva and could be malignant.
    UNASSIGNED: An Afro-American adult male developed two distinct conjunctival growths on his left lower lid. One growth was pedunculated and the second one sessile. The initial diagnosis of \'benign conjunctival papillomas\' was made. Patient was recommended to wait and watch. After about two years the neoplasia had doubled their sizes. Surgical excisional biopsy was performed for diagnostic and therapeutic reasons. The tumor beds were treated with intra-operative cryotherapy using liquid nitrogen and applying double-freeze-thaw technique. Histopathology proved the masses to be benign and caused by HPV. Recurrence and seeding of virus during surgical excision leading to multiple new masses are dreaded complications during management of conjunctival papilloma. Though a short follow-up, yet after three months there were no signs of recurrence.
    UNASSIGNED: A brief review of literature is presented to highlight the fact that rarely such conjunctival papillomas may develop at unusual sites and in adults. We believe that the uncommon demographic and anatomic presentation of this case is worth sharing with ophthalmic community.

    肛门的纤维上皮息肉已被描述为响应于慢性刺激或组织损伤的粘膜肥大。病变通常很小,并且主要存在于患有局部疾病的老年人中。病例报告:一名原本健康的15岁男性,表现出巨大的花梗肿块,从肛门边缘伸出,扩大了2年,造成不适。结果:经手术切除和组织学检查,肿块类似于纤维上皮息肉,淋巴管扩张。结论:虽然文献描述了此类病变可能的病理学谱,通常由基质和上皮成分的混合物组成,扩张的淋巴管不太常见。这种巨大的肛门纤维上皮息肉的特征是水肿基质和许多扩张的淋巴管,与淋巴管瘤一致。据我们所知,在这个年龄组中,这种介绍是新颖的,没有潜在的危险因素.
    UNASSIGNED: Fibroepithelial polyps of the anus have been described as mucosal hypertrophy in response to chronic irritation or tissue damage. Lesions usually remain small and mostly present in elderly adults with local disease. Case Report: An otherwise healthy 15-year-old male presented with a giant pedunculated mass projecting out of the anal verge that enlarged over 2 years, causing discomfort. Results: Upon surgical excision and histologic examination, the mass resembled a fibroepithelial polyp with numerous dilated lymphatics. Conclusions: While literature describes the spectrum of pathology possible in such lesions, often consisting of a mixture of stromal and epithelial components, dilated lymphatics are less common. This giant anal fibroepithelial polyp characterized by edematous stroma and numerous dilated lymphatics is consistent with lymphangioma. To our knowledge, this presentation is novel in this age group with no underlying risk factors.

    背景:室管膜下瘤是罕见的良性,非侵袭性肿瘤,被世界卫生组织列为低度肿瘤。国际数据估计其频率在颅内肿瘤的0.2%至0.7%之间,它们通常是尸检中的偶然发现。最好位于第四脑室,当这些肿瘤通过阻塞脑脊液循环引起脑积水时,它们往往会出现症状。
    方法:我们介绍病态肥胖的情况,高血压,糖尿病患者,出现步态共济失调症状的人,括约肌失禁,和与左侧脑室带蒂室管膜下瘤有关的异常。他接受了显微显微外科手术的双顶开颅手术,通过它实现了总的全切除。无围手术期并发症发生。
    结论:鉴于其良性行为和对手术治疗的良好反应,室管膜下瘤应及时诊断和手术治疗,以避免出现症状时可能的神经损伤。
    BACKGROUND: Subependymomas are rare benign, noninvasive tumors, classified by the World Health Organization as low grade neoplasms. International data estimate their frequency between 0.2% and 0.7% of the intracranial tumors, and they usually are an incidental finding in autopsies. Preferably located in the fourth ventricle, these tumors tend to become symptomatic when they cause hydrocephalous by obstructing cerebrospinal fluid circulation.
    METHODS: We present the case of a morbidly obese, hypertense, and diabetic patient, who presented with symptoms of gait ataxia, sphincter incontinence, and dysartria in relation to a pedunculated subependymoma in the left lateral ventricle. He underwent a biparietal craniotomy with a microscopic microsurgical approach, through which gross total resection was achieved. No perioperative complications ensued.
    CONCLUSIONS: Given their benign behavior and their excellent response to surgical treatment, subependymomas should be promptly diagnosed and surgically treated to avoid possible neurological damage when they become symptomatic.
