Abstract
Background: We incidentally observed CD138 (syndecan-1) expression in a cellular neurothekeoma (CNT) and sought to investigate whether this is a consistent finding in these tumors.
Methods: We evaluated a series of 20 skin biopsy specimens diagnosed as CNT for CD138 immunohistochemical staining in comparison to the more traditional CNT immunohistochemical stains, NKI/C3 and MITF. Control cases of xanthogranuloma (XG), dermal Spitz nevi, and epithelioid fibrous histiocytomas (EFH) were included based on similar histopathologic morphology.
Results: CD138 expression in a membranous and reticulated extracellular pattern was observed in 95% of CNT cases evaluated. NKI/C3 was expressed in 83% of CNT, and MITF in 72%. Of the control cases, 10% of XG, 10% of dermal Spitz nevi, and 17% of EFH expressed CD138.
Conclusions: Our data suggest that CD138 may be a useful adjunctive marker in the diagnosis of CNT, particularly when utilized in a panel with other established markers such as NKI/C3 and MITF.
期刊介绍：
Journal of Cutaneous Pathology publishes manuscripts broadly relevant to diseases of the skin and mucosae, with the aims of advancing scientific knowledge regarding dermatopathology and enhancing the communication between clinical practitioners and research scientists. Original scientific manuscripts on diagnostic and experimental cutaneous pathology are especially desirable. Timely, pertinent review articles also will be given high priority. Manuscripts based on light, fluorescence, and electron microscopy, histochemistry, immunology, molecular biology, and genetics, as well as allied sciences, are all welcome, provided their principal focus is on cutaneous pathology. Publication time will be kept as short as possible, ensuring that articles will be quickly available to all interested in this speciality.
