G-CSF-producing giant squamous cell carcinoma (SCC): changes in serum G-CSF in parallel with SCC antigen.

Sir, Squamous cell carcinoma (SCC) can occur anywhere on the skin and in mucous membranes with a squamous epithelium (1). Malignant tumours producing granulocyte colony-stimulating factor (G-CSF) have been reported in lung cancer, thyroid carcinoma, bladder carcinoma and cutaneous angiosarcoma (2). We encountered a case of G-CSF-producing SCC, which was diagnosed by immunohistochemical staining and showed changes in serum G-CSF in parallel with the serum SCC antigen level and the disease course.
