Although, as already specified, breast neoplasms, small cell lung tumours, and gynaecological neoformations are those most associated with paraneoplastic syndromes with neurological involvement, particularly with cerebellar degeneration, thymoma, testicular neoplasms, and Hodgkin’s lymphoma are also significantly associated with this pathology; in fact, other antibodies of possible finding are anti-CV2, related to thymoma and microcytoma, anti-Ma2, associated with testicular malignancy, and anti-Tr, present in patients with Hodgkin’s lymphoma [4]. This evidence concerns the gene DPYSL5 and breast neoplasm.
