Paraneoplastic cerebellar degeneration is a rare non-metastatic complication of malignancies. It presents with acute or subacute onset of ataxia, dysarthria and intention tremor. Paraneoplastic cerebellar degeneration is most commonly associated with malignancies of the ovary, breast and lung. The anti-Yo (anti-Purkinje cells) antibodies that specifically damage the Purkinje cells of the cerebellum are found in the serum and cerebrospinal fluid. Anti-Yo-related paraneoplastic cerebellar degeneration is most commonly found in women with gynecological and breast cancers, but it is reported in other malignancies. Patients with paraneoplastic syndromes most often present with neurologic symptoms before an underlying cancer is detected. We report a case of anti-Yo-related paraneoplastic cerebellar degeneration associated with pleural malignant mesothelioma in a 51-year-old female patient. She presented to our department with a 2-week history after the last chemotherapy of progressive dizziness related to head movement, nausea, vomiting, ataxia and unsteady gait. A western blot assay was negative for anti-Hu, anti-Ri, anti-Ma2, anti-CV2 and anti-amphiphysin paraneoplastic antibody markers but positive for anti-Yo. In conclusion, we report a case of paraneoplastic cerebellar degeneration in a patient with pleural malignant mesothelioma because of the rarity of this neurologic presentation after the diagnosis of malignant mesothelioma and of the association with anti-Yo antibodies.

Background. Stiff person syndrome (SPS) is a rare neurological disorder characterized by progressive rigidity of axial and limb muscles associated with painful spasms. SPS can be classified into classic SPS, paraneoplastic SPS, and SPS variants. Its underlying pathogenesis is probably autoimmune, as in most cases antibodies against glutamic acid decarboxylase (GAD) are observed. Similarly, paraneoplastic SPS is usually linked to anti-amphiphysin antibodies. Treatment is based on drugs enhancing gamma-aminobutyric acid (GABA) transmission and immunomodulatory agents. Case Series. Patient 1 is a 45-year-old male affected by the classic SPS, Patient 2 is a 73-year-old male affected by paraneoplastic SPS, and Patient 3 is a 68-year-old male affected by the stiff limb syndrome, a SPS variant where symptoms are confined to the limbs. Symptoms, diagnostic findings, and clinical course were extremely variable in the three patients, and treatment was often unsatisfactory and not well tolerated, thus reducing patient compliance. Clinical manifestations also included some unusual features such as recurrent vomiting and progressive dysarthria. Conclusions. SPS is a rare disorder that causes significant disability. Because of its extensive clinical variability, a multitask and personalized treatment is indicated. A clearer understanding of uncommon clinical features and better-tolerated therapeutic strategies are still needed.
