Abstract
Anaplastic lymphoma kinase-positive histiocytosis, first reported in 2008, is a rare, novel type of neoplasm. To date, no more than 100 cases of anaplastic lymphoma kinase-positive histiocytosis have been reported. In this retrospective study, 12 cases of anaplastic lymphoma kinase-positive histiocytosis, including clinical symptoms, histological features, molecular pathology, treatment, and prognosis, in children were analyzed to gain a deeper understanding of the disease. All patients were Asian children, aged 2 months to 8 years and 2 months (mean 3.1 years), and the male-to-female ratio was 5:7. All patients were followed up closely. One patient died during the follow-up period, seven (case 1–7) had focal anaplastic lymphoma kinase-positive histiocytosis, and five (case 8–12) had multisystem anaplastic lymphoma kinase-positive histiocytosis. In addition, we report the case of a patient who benefited from anaplastic lymphoma kinase-targeted therapy and a patient with the rare EML4-ALK fusion gene. The current study is expected to substantially contribute to increasing the awareness of anaplastic lymphoma kinase-positive histiocytosis.
期刊介绍：
Human Pathology is designed to bring information of clinicopathologic significance to human disease to the laboratory and clinical physician. It presents information drawn from morphologic and clinical laboratory studies with direct relevance to the understanding of human diseases. Papers published concern morphologic and clinicopathologic observations, reviews of diseases, analyses of problems in pathology, significant collections of case material and advances in concepts or techniques of value in the analysis and diagnosis of disease. Theoretical and experimental pathology and molecular biology pertinent to human disease are included. This critical journal is well illustrated with exceptional reproductions of photomicrographs and microscopic anatomy.
