Laparoscopic surgical management and clinical characteristics of ovarian fibromas

Objective:

This study aims to analyze the clinical characteristics and diagnostic features of ovarian fibromas and to evaluate the efficacy and safety of laparoscopic surgery for ovarian fibromas.

Methods:

We reviewed the records of 47 consecutive women who underwent laparoscopic or laparotomic surgeries and whose final histopathological diagnoses were ovarian fibroma, cellular fibroma, or fibrothecoma from January 1999 to August 2010.

Results:

During the study period, 49 tumors were removed from 47 women including 27 ovarian fibromas, 19 fibrothecomas, and 3 cellular fibromas. The preoperative diagnoses were ovarian fibroma in 25 women (53.2%) and uterine myoma in 16 women (34.0%). A high serum CA 125 level (>35U/mL) was observed in 15 women, and serum CA 125 level was significantly higher in women with ascites (P=<0.001). The tumors were removed surgically in all women, using the laparotomic approach in 16 women (34.0%) and the laparoscopic approach in 31 women (66.0%). The laparoscopic surgery had the advantages of shorter hospital stay and faster return of bowel activities compared to laparotomy.

Conclusions:

Ovarian fibromas are often misdiagnosed as uterine myomas, and sometimes mistaken for a malignant tumor of the ovary preoperatively. Laparoscopic surgery can be an effective and safe surgical approach for managing ovarian fibromas.     

Desmoplastic Fibroblastoma (Collagenous Fibroma): A Case Identified in the Buccal Mucosa

Desmoplastic fibroblastoma is a rare, benign, soft tissue tumor affecting mainly the subcutaneous and muscle tissue. Only five cases identified in the oral cavity have been reported in prior literature. This article presents a case report of a 56-year-old man, with no previous history of trauma, who presented a slow-growing mass in the buccal mucosa. Histopathology and immunohistochemistry staining studies were performed, and a diagnosis of the desmoplastic fibroblastoma was made. The patient has been disease-free for one year.     

牙骨质-骨化纤维瘤的X线表现及其病理学分析

目的 观察牙骨质-骨化纤维瘤的X线表现,并探讨其X线表现的病理学基础.方法 牙骨质-骨化纤维瘤患者25例,男性7例,女性18例,初诊年龄12-65岁,平均38.5岁,上颌4例,下颌21例.观察牙骨质-骨化纤维瘤的X线表现,并从其病理表现分析其病理学基础.结果 牙骨质-骨化纤维瘤的X线表现共分为三类:(1)密度减低影像.病理学上主要为富含成纤维细胞的纤维结缔组织构成.(2)密度减低-密度增高的混合影像.病理学上主要为含有牙骨质团块、编织骨及小梁状骨的纤维结缔组织构成.(3)密度增高影像.病理学上主要为牙骨质团块及小梁状骨构成,而纤维结缔组织成分较少.结论 随着牙骨质-骨化纤维瘤病变内部硬组织含量和钙化程度的不同,从而有不同的X线表现,并且结合X线表现及其病理学基础,能够判断牙骨质-骨化纤维瘤的病变特性.

乳腺纤维瘤的超声诊断价值

目的探讨彩色超声对乳腺纤维瘤诊断的价值,提高乳腺纤维瘤患者的早期诊断率。方法选择2009年12月-2011年11月本院做乳腺检查的60例乳腺纤维瘤患者,使用美国GELogic7彩色多普勒超声诊断仪．探头频率为5-12MHz。结果（1）典型的声像图表现的患者为46例,非典型的患者为14例;（2）手术病理证实有38例乳腺纤维瘤,占全部的63-3％。结论彩色超声可以用来作为乳腺纤维瘤的诊断依据,为临床治疗提供了重要依据,值得在基层医院进一步推广使用。     

非骨化性纤维瘤的影像学表现及病理对照研究

目的 分析非骨化性纤维瘤(NOF)的X线及CT表现,并结合病理特征,以提高NOF的诊断与鉴别诊断水平.方法 回顾性分析28例经手术病理证实的NOF患者X线及CT表现.结果临床症状轻微,好发于长管状骨的干骺端或骨干,病变发生于胫骨18例,股骨9例,肱骨1例,皮质型19例,表现为皮质内或紧贴皮质下的单房或多房透亮区,周围有致密的硬化带环绕;髓质型9例,病灶在骨内呈中央性发展,显示单房或多房透亮区,边缘硬化,骨皮质变薄,轻度向周围膨隆.结论 NOF的影像学表现具有一定的特征性,X线及CT是诊断NOF的非常有用的方法,多层螺旋CT的薄层扫描及多平面重建能更清晰地显示NOF的影像特征.     

Giant-cell-rich tumors of bone

Neoplasms of bone with numerous non-neoplastic osteoclast type giant cells are relatively common and exhibit diverse phenotypes of the neoplastic cells. These tumors have a broad spectrum of biological potential which necessitates accurate recognition and diagnosis. Their clinicopathological features are overlapping, therefore, immunohistochemistry and molecular studies may be required for evaluation. Correlation with imaging studies provides additional information that should be incorporated into the pathological interpretation.     

There is fat in this sclerosis: A case report of sclerotic lipoma and review of the literature

Sclerotic lipomas, a lipoma variant, are benign subcutaneous tumors, so-named because of their resemblance to sclerotic fibromas. Previous literature has suggested that these tumors may show a predilection for middle-aged adult males. We report an unusual case of a sclerotic lipoma diagnosed on the scalp of a 66-year-old female. The patient presented to the outpatient clinic with a 3- to 4-year history of an enlarging and irritated 2.6-cm nodule on the anterior crown of the scalp, clinically thought to be a pilar cyst. Histopathological examination from the excisional specimen revealed a well-circumscribed dermal to subcutaneous tumor with ample sclerotic collagen bundles, an increased number of CD34 positive spindled cells, and prominent S-100 positive mature adipocytes comprising greater than 50% of the tumor. We present this case given its atypical clinical and histopathological presentation, review the literature of sclerotic lipomas, and discuss the differential diagnosis to raise awareness of this rare entity.     

鼻腔鼻窦青少年型骨化纤维瘤六例临床分析

目的 分析鼻腔鼻窦青少年骨化纤维瘤的临床特点,并探讨治疗方法。 方法 选取2015年5月至2017年12月治疗的6例鼻腔鼻窦青少年骨化纤维瘤,男4例、女2例,年龄2个月~12岁6个月,中位年龄6岁2个月。肿瘤发生于上颌窦1例,筛窦3例,蝶窦1例,额窦1例。患儿入院后均行手术治疗,1例患儿肿物累及视神经,为保留患儿视力行鼻内镜下肿物部分切除术,术后半年发现肿物累及视神经并广泛累及颅底,行第2次鼻内镜下肿物部分切除术,术后半年因肿物复发且累及范围广泛,在第3次手术时行右侧鼻侧切开联合鼻内镜下鼻-鼻窦骨化纤维瘤部分切除术。其余患儿均行鼻内镜下肿物切除术。除1例年龄为2个月的患儿未行导航CT检查外,患儿术中均采用美敦力FUSION ENT Image Guidance System电磁导航技术对肿物边缘予以定位。另有1例患儿因肿物位于蝶窦且有明确的滋养血管,鼻内镜术前1 d予以介入血管造影及栓塞术。患儿术后均定期随访,包括鼻内镜检查及鼻窦CT检查,了解患儿术区情况、症状是否缓解及有无并发症出现。 结果 6例患儿病理分型为砂砾样5例,小梁状1例。患儿均未失访,平均随访时间2.2年。其中1例复发,予以肿物部分切除,术后带瘤生存。其余患儿随访期内均未发现肿物复发且无并发症出现,患儿的原发症状均得到有效缓解。 结论 鼻腔鼻窦青少年骨化纤维瘤具有侵袭性生长和术后易复发的临床特点,手术是惟一有效的治疗方法。影像导航下鼻内镜手术是适合儿童的术式。     

钙化性腱膜纤维瘤2例临床病理分析

目的:探讨钙化性腱膜纤维瘤(CAF)临床病理特点、免疫组化、病理诊断与鉴别诊断要点。方法:分析2例CAF临床病理特点、免疫组化、治疗与预后并复习相关文献。结果:CFA好发于青少年手掌和足底。肿瘤多< 3 cm,界不清;切面呈灰白色,质硬。镜下可见增生的纤维母细胞、散在分布的钙化小灶及软骨小岛。免疫组化:vimentin（+）,SMA（+）,CD68（+）,CD99（+）。结论:CAF是一种少见的良性软组织肿瘤,其诊断需要结合临床病理形态学特点及免疫组化,且还需与腱鞘巨细胞瘤、软骨母细胞瘤、肿瘤样钙盐沉着症、掌跖纤维瘤病、婴儿型纤维瘤病、婴儿纤维性错构瘤、软组织软骨瘤、单相纤维型滑膜肉瘤鉴别。
