To date, only 3 patients with MF have been reported with clinically detectable pancreatic metastases.[74–76] Ceriolo et al[74] hypothesized that a potential mechanism for pancreatic metastasis in MF involves the expression of the CCL27 chemokine by glucagon-secreting cells within the pancreatic islets. The gene discussed is GCG; the disease is mycosis fungoides.
