Skin window studies in polycythaemia rubra vera. 1975

M L Ghosh, and G Hudson, and E K Blackburn

The inflammatory response was studied in patients with primary polycythaemia by means of a modified skin window technique. In untreated patients, the overall cellularity was a prominent feature and, as compared with the controls, the 48 h preparations showed a significantly greater percentage of granulocytes with a corresponding decreased percentage of macrophages. In the peripheral blood of these patients, both total white cells and granulocyte counts were significantly higher than in the control subjects. A highly significant relationship between the blood and skin window neutrophils was demonstrated. In polycythaemia patients in remission, the results were generally similar to the controls, except that there was still a highly significant increase in the percentage of skin window basophils. The results provided no evidence of a defect in cell migration or in the phagocytic activity of macrophages in polycythaemia vera. Possible mechanisms of the cutaneous basophilia and its relevance to the manifestation of this disorder are discussed.

UI	MeSH Term	Description	Entries
D007958	Leukocyte Count	The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells.

D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D011087	Polycythemia Vera	A myeloproliferative disorder of unknown etiology, characterized by abnormal proliferation of all hematopoietic bone marrow elements and an absolute increase in red cell mass and total blood volume, associated frequently with splenomegaly, leukocytosis, and thrombocythemia. Hematopoiesis is also reactive in extramedullary sites (liver and spleen). In time myelofibrosis occurs.
