abstract = {Myasthenia gravis (MG) is a heterogeneous autoimmune
disease, which is characterized by a postsynaptic
neuromuscular transmission defect, with antibodies directly
targeting the acetylcholine receptor (AChR) or other
structural proteins of the neuromuscular junction. The
majority of MG cases are associated with thymic pathologies,
including thymoma, thyroiditis, autoimmune diseases or
malignant hematologic neoplasia. The present study reported
a rare case of AChR-positive and late-onset ocular MG, which
rapidly progressed to a generalized myasthenic syndrome as
an initial presentation of a pancreatic neuroendocrine
neoplasia (pNEN). Following complete surgical resection of
the pNEN, the myasthenic syndrome was improved and the
anti-AChR antibody titers were reduced. It has been reported
that MG is a paraneoplastic syndrome in thymic neoplasms and
less common in hematologic malignancies. However, currently,
only few cases of MG as initial presentation of a solid
tumor, and more particular of a neuroendocrine neoplasm,
have been reported in the literature. In conclusion,
surveillance for extrathymic solid malignancies in newly
diagnosed patients with MG could promote the early diagnosis
of associated tumor diseases.},
