Cutaneous secretory carcinoma McKee, Grishakov, Arida & Hernane

Primary cutaneous secretory carcinoma is exceedingly rare. Before making the diagnosis it is important to make sure that it is not arising in a salivary gland or breast. Although considered to be a low grade tumor, a recent publication where a patient developed nodal and lung metastases challenges this supposition. Most tumors are associated with the ETV6-NTRK3 fusion gene.
