Abstract

Factor XIIIa, a blood coagulation factor, has been found in a variety of cell types, including dendritic reticulum cells and fibroblast-like mesenchymal cells. We hypothesized that fibrous papule, a lesion of uncertain histogenesis, was composed of dermal stellate cells and in this report demonstrate that this neoplasm consists of cells that contain this factor. Nevus cells do not contain factor XIIIa.

摘要

凝血因子XIIIa已在多种细胞类型中被发现，包括树突状网状细胞和成纤维细胞样间充质细胞。我们推测，组织发生不明的损害——纤维性丘疹，是由真皮星状细胞构成，并且在本报告中证实这种肿瘤由含有该因子的细胞组成。痣细胞不含因子XIIIa。
