Leiomyosarcoma in the humerus with leukocytosis and elevation of serum G-CSF

Abstract: Leukocytosis associated with secretion of granulocyte colony-stimulating factor (G-CSF) has been reported in various tumors, primarily poorly differentiated epithelial tumors, but is extremely rare in bone tumors. An 84-year-old woman experienced swelling and pain in the shoulder for 1 month. Leukocytosis and elevated serum G-CSF were observed, but resolved following tumor resection. A diagnosis of leiomyosarcoma of the bone with expression of G-CSF was confirmed immunohistochemically. Histological diagnosis o… Show more

“…[1][2][3] Su presentación ósea es rara; en la literatura, la información respecto al LMS intraóseo es escasa, y la mayoría corresponde a reportes de caso. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Se presenta el caso de una paciente con un LMS primario óseo en fémur distal izquierdo primario, tratado quirúrgicamente y con quimioterapia, en quien posteriormente, durante el seguimiento, se identificó una lesión metastásica en clavícula con fractura patológica manejada con resección quirúrgica.…”

“…Leukocytosis with non-clonally derived mature neutrophils, due to paraneoplastic production of granulocyte colony-stimulating factor (G-CSF) is a rare phenomenon and has been described in a variety of different tumors [2,3]. Most cases are associated with gastrointestinal, lung, or genitourinary carcinomas [4-8]. G-CSF producing tumors are typically poorly differentiated and patients are diagnosed in an advanced stage with a large tumor burden [9,10].…”
