Summary A novel human myeloid cell line, designated HSM‐1, has been established from the pleural effusion of a patient with granulocytic sarcoma (GS) who had been followed as having primary myeiofibrosis for 10 years. When he was diagnosed as having granulocytic sarcoma in dermal tissues, no evidence of malignant transformation into leukaemia was found in both the peripheral blood and bone marrow. The established cell line was positive for myeloperoxidase, Sudan black B. Naphthol AS‐D chloroacetate esterase. Surface marker analysis revealed that HSM‐1 expressed CD4. CD13, CD11a, CDllb, Leu8. CD49b. CD49d, CD49e, CD29 and HLA‐DR. To clarify why the unusual myeloid tumours developed in non‐haematopoietic tissues, we examined the capability of HSM‐1 to bind to skin fibroblast layers. The HSM‐1 cells were found to bind to both bone marrow stromal layers and skin fibrobiast layers. Among the other myeloid ceil lines tested, none was found to bind to skin flbroblast layers. These findings suggest that the GS cell line may be derived from a haematopoietic precursor cell which can bind to skin fibroblasts and is localized in non‐haematopoietic tissues resulting in the formation of extramedullary myeloid metaplasia. HSM‐1 is a useful tool for analysing the characteristics of granuiocytic sarcoma and homing receptors for haematopoietic stem cells.
