Dacrocyte (original) (raw)
A dacrocyte (or dacryocyte) is a type of poikilocyte that is shaped like a teardrop (a "teardrop cell"). A marked increase of dacrocytes is known as dacrocytosis.These tear drop cells are found primarily in diseases with bone marrow fibrosis, such as: primary myelofibrosis, myelodysplastic syndromes during the late course of the disease, rare form of acute leukemias and myelophthisis caused by metastatic cancers. Rare causes are myelofibrosis associated with post-irradiation, toxins, autoimmune diseases, metabolic conditions, inborn hemolytic anemias, iron-deficiency anemia or β-thalassemia.

(en) Dacryocyte est un terme issu du grec dakuron: larme et kutos: cellule Les dacryocytes sont des globules rouges en forme de larmes. Une prolifération de dacryocytes est appelée une dacryocytose. Une dacryocytose se voit souvent dans les myélofibroses, les thalassémies et toute hématopoïèse extramédullaire. (fr) Il dacriocita è un eritrocita a forma di lacrima. La sua presenza nel sangue, denominata dacriocitosi, è una forma di poichilocitosi. Rappresenta il segno tipico della mielofibrosi e dell'anemia mieloftisica e si formano solo in caso di emopoiesi extramidollare e solo se la milza è intatta. La loro assenza rende improbabile la diagnosi di mieloftisi, ma la loro presenza non è specifica per tale malattia. Infatti può essere presente inoltre nell'anemia megaloblastica e, occasionalmente, nelle sindromi mielodisplasiche e mieloproliferative, nella talassemia e nell'anemia sideropenica. (it) |
