Langerhans cell histiocytosis [PDF]
Abstract Langerhans cell histiocytosis (LCH) is caused by clonal expansion of myeloid precursors that differentiate into CD1a+/CD207+ cells in lesions that leads to a spectrum of organ involvement and dysfunction. The pathogenic cells are defined by constitutive activation of the MAPK signaling pathway.

Background Langerhans cells belong to the histiocytic system and give rise to two tumors: Langerhans cell histiocytosis and Langerhans cell sarcoma. Clinical aggressiveness and degree of atypia distinguish the two neoplasms. Langerhans cell histiocytosis

Langerhans cell histiocytosis developing acute lymphoblastic leukemia
The sequential occurrence of Langerhans cell histiocytosis and acute leukemia in only one individual has been reported previously; however, it is rarely observed that Langerhans cell histiocytosis can transform into acute lymphoblastic leukemia, and the ...

Lymphangiogenesis and angiogenesis during human fetal pancreas development [PDF]
Background: The complex endocrine and exocrine functionality of the human pancreas depends on an efficient fluid transport through the blood and the lymphatic vascular systems. The lymphatic vasculature has key roles in the physiology of the pancreas and
