摘要
目的:探讨原发性皮肤间变性大细胞淋巴瘤(ALCL)临床及病理特征。方法:复习4例患者的临床资料、肿瘤组织的病理形态和免疫表型。结果:4例中男3例,女1例,平均年龄为55.5岁。患者临床上均表现为皮下结节。光镜下以75%以上CD30^+间变性大细胞弥漫浸润真皮及皮下脂肪组织为特征,多数瘤细胞表达T细胞免疫表型。随访3例12—36个月肿瘤均无复发或转移。结论:原发性皮肤ALCL是少见的低度恶性T细胞性淋巴瘤,预后较好。依据其组织病理学特征及免疫组化CD30阳性标记,可与其他恶性肿瘤进行鉴别。
Objective: To analyze the clinicopathologic characteristics of primary cutaneous anaplastic large cell lymphoma (ALCL). Methods: The clinical history, histopathological changes and expression in 4 cases of primary cutaneous ALCL were investigated. Results: There were 3 males and 1 female with an average age of 55.5 years. All patients presented with subcutaneous masses. The lymphoma was characterized by a dermal and subcutaneous infiltration of atypical large cells. More than 75 % of the neoplastic cells were CD30^+ and expressed T- cell immunophenotype. No recurrences or metastases were found in the follow- up of 3 cases for 12 - 36 months. Conclusion: Primary cutaneous ALCL is a rare low- grade malignancy with a generally favorable outcome. This tumor can be differentiated from other malignant tumors by means of histopathologic features and positive expression of CD30.
