目的:探讨成人恶性睾丸间质细胞瘤的临床病理特点,明确适宜的治疗方式.方法:回顾性分析我院从1997年6月至2009年12月诊治的3例成年恶性睾丸间质细胞瘤患者,分析其临床资料包括症状体征、实验室检查、影像学检查、治疗方式、病理结果及随访情况.结果:3例患者均行睾丸根治性切除术.1例患者术后9个月出现淋巴结转移,13个月出现肺转移并于术后26个月死于肿瘤广泛转移;另2例患者术后即刻行腹膜后淋巴结清扫发现了CT未提示的腹膜后淋巴结转移,其中1例术后43个月出现肺转移.结论:部分成人睾丸间质细胞瘤呈恶性病程,需严密随诊.腹膜后淋巴结清扫术具有诊断价值,转移患者预后较差. 相似文献

We describe a rare case of basosquamous carcinoma (BSC) in a 69‐year‐old man. He had noticed a pigmented nodule on his left thigh. Dermoscopic examination showed ulceration at the center and non‐typical leaf‐like areas at the periphery. Linear‐irregular vessels were also seen. He underwent tumor excision in addition to sentinel lymph node biopsy (SLNB). Histopathological examination revealed both features of basal cell carcinoma (BCC) and squamous cell carcinoma. The sentinel lymph node was positive for tumor cells. Immunostaining for Ber‐EP4 was focally positive for invasive tumor cells. Although complete inguinal lymphadenectomy had been performed, multiple in‐transit metastases around the primary lesion and left iliac lymph node metastasis developed after the operation. It is considered that BSC has a worse prognosis than BCC with a potential for metastasis. Based on the findings of previously reported cases and our case, SLNB may be applied for certain high‐risk cases including BSC larger than 3 cm in size and careful follow up is recommended for patients with BSC. 相似文献

目的:探讨皮肤鳞状细胞癌(简称鳞癌)中基质金属蛋白酶2(MMP-2)、金属蛋白酶组织抑制因子2(TIMP-2)的表达及其与肿瘤分化程度和淋巴结转移的关系。方法:用ABC免疫组化技术观察50例皮肤鳞癌(高分化鳞癌34例,低分化鳞癌16例,其中14例淋巴结转移)。结果:MMP-2与TIMP-2均表达于瘤细胞和癌旁间质细胞、血管内皮细胞质中。MMP-2表达阳性率为76%(38/50),在低分化鳞癌组中的表达明显高于高分化组(P=0.021)和有淋巴结转移组(P=0.003)。TIMP-2表达阳性率为74%(37/50),在高分化或无淋巴结转移的鳞癌组中的表达明显高于低分化(P=0.010)或有淋巴结转移组(P=0.018)。结论:皮肤鳞癌中MMP-2和TIMP-2表达与其分化程度及淋巴结转移有关。 相似文献

A 68-year-old white man with type 1 neurofibromafosis presented with a 1 -year history of a pruritic non-healing eruption on his left breast. The persistent lesion had been gradually enlarging. This had been unsuccessfully treated with both corticosteroid and antifungal creams. Physical examination of the involved breast revealed a well-demarcated 5 × 3 cm red, slightly Jnfiltrated piaque with adherent fine white scale and erosions with serous exudate (Fig. 1). The areola was completely obscured by the lesion and the nipple could not be identified. Neither a breast mass nor axillary adenopathy was present. A punch biopsy confirmed the diagnosis of Paget's disease. The patient subsequently underwent a left modified radical mastectomy with ipsilateral lymph node dissection. The final pathology revealed intraductal carcinoma, comedo and noncomedo type, with overlying pagetoid cells in the epidermis (Figs 2–4). Special stains included a positive epithelial membrane antigen, focally positive carcinoembryonic antigen, and negative S-100. All 21 lymph nodes submitted from the axillary lymph node dissection were negative for tumor. 相似文献

Cutaneous metastasis of visceral tumors accounts for 2% of skin tumors. We report the case of a 71‐year‐old male with a smoking history who presented to dermatology department with a violaceous nodule of the right sideburn skin. The lesion was interpreted as an adenocarcinoma that was completely excised and was suspicious for a metastasis. There was a recommendation for additional work‐up. At a different institution, a positron emission tomography scan showed a left hilar mass and uptake in the right thyroid. He was then referred to our hospital for tissue diagnosis. Mediastinoscopy with biopsy of the left hilar mass showed metastatic follicular thyroid carcinoma. Subsequently, a thyroid fine needle aspirate showed suspicion for malignancy with similar morphology. Thyroidectomy and central neck dissection showed right thyroid papillary carcinoma extending to one margin and involving the lymph nodes. The left hilar metastasis mass resection showed similar lymph node findings. A re‐review of the sideburn excision revealed similar histopathology to the thyroid and mediastinal resection. This case illustrates the opportunity of considering metastatic thyroid carcinoma to skin even in cases which lack the classic cytologic and architectural features of papillary thyroid carcinoma follicular variant. 相似文献

目的:分析纳米炭混悬注射液作为SLN示踪剂对早期宫颈癌盆腔淋巴结转移状态预测价值。方法:选取我院2015年2月至2015年12月妇科门诊及住院部确诊为浸润性宫颈癌的患者42例。注射纳米炭混悬注射液作为SLN示踪剂,切除黑染淋巴结。然后所有患者均进行广泛子宫切除术和腹腔镜盆腔淋巴结清扫术,标本送往实验室进行病理检验。结果:42例患者中40例检出SLN出现黑染,其中30例双侧均出现黑染。共清除出1004枚盆腔淋巴结,平均每例患者共切除23.9个淋巴结,每例患者平均SLN检验出的淋巴结为3.9。病理结果表明SLN准确率为100%,而假阴性为0%。结论:SLN被检测出来的淋巴引流区最多的是闭孔,其与盆腔淋巴结的转移具有一致性,且初步证明了纳米炭混悬液作为SLN示踪剂检测宫颈癌的安全性和可靠性。 相似文献

Sentinel node biopsy (SNB) is increasingly being used as a minimally invasive staging procedure in patients with malignant melanoma. For decades elective lymph node dissection (ELND) was performed in many centers on patients at risk for lymph node metastasis but without clinically detectable lymph node involvement. Today, selective lymph node dissection (SLND) is offered only to patients with histologically proven metastasis in a SN (10-29%). A positive SN is one of the most important prognostic parameters. Ten years after the introduction of the technique, the role of SNB in the treatment of cutaneous melanoma still remains controversial. Issues include the usefulness of highly sensitive evaluation of SN using molecular biology or cytology techniques, as well as the therapeutic impact of the SNB per se and the associated combined surgical or medical adjuvant therapies. 相似文献

Cutaneous clear cell sarcoma (CCS) is a rare soft tissue malignancy that typically manifests in the distal extremities of young adults. Although it shows melanocytic differentiation, CCS is clearly pathologically and genetically distinct from malignant melanoma. Here, we report the case of a 43-year-old male who had an asymptomatic, deep-seated, slowly enlarging, firm mass over the right heel for 30 years that recently and rapidly progressed with tenderness. We arranged for the total excision of the tumor. Pathological and cytogenetic analysis of the biopsied specimen showed that it was a clear cell sarcoma. Computed tomography and positron emission tomography scans showed no signs of metastasis, and no other abnormal hypermetabolic lesions were detected. Wide excision with split-thickness skin graft and a sentinel lymph node biopsy were performed. Because of positive findings in the sentinel lymph nodes, the patient was transferred to the plastic surgery department for further radical popliteal and inguinal lymph node dissection. The patient has received regular outpatient follow-up care in our hospital for the past 8 months with no evidence of recurrence. 相似文献

Twelve cases of eccrine porocarcinoma have been reported at our facility in the past 10 years. All of them were Japanese; half had lymph node metastases; and one-third died of this disease. Lymph node metastasis was correlated with pathological lymphovascular invasion. Death was correlated with a pathological growth pattern and clinical lymph node metastasis. Sentinel lymph node biopsy was performed usefully in two patients. 相似文献
