A 68-year old man experienced a progressive proximal tetraparesis with anhidrosis and a single episode of horizontal diplopia before presenting exertional dyspnea; pulmonary investigations revealed a small cell carcinoma of the lung. Clinical and electrophysiological investigations with abnormal SFEMG, repetitive stimulations and autonomic assessment pointed to a pre-synaptic neuromuscular dysfunction compatible with a Lambert-Eaton syndrome. Antibodies to acetylcholine receptors and calcium channels were negative. Thoracic radiotherapy combined with chemotherapy produced marked improvement: repeated electrophysiological evaluations showed a strong correlation between median nerve CMAP amplitude and clinical course. This case prompted us to discuss current concepts of pre-synaptic dysfunction, and paraneoplastic syndrome, and to review therapeutic strategies, in the light of recent studies of Lambert-Eaton syndrome.

Thymoma is an uncommon canine neoplasm of thymic epithelial cells. It is seen in various breeds but may occur more frequently in German Shepherd Dogs. Middle-aged or older dogs can be affected and no sex predilection exists. A paraneoplastic syndrome of myasthenia gravis, nonthymic malignant tumors, and/or polymyositis occurs in a significant number of dogs with thymoma. Clinical signs are variable and are related to a space-occupying cranial mediastinal mass and/or manifestations of the paraneo-plastic syndrome. Dyspnea is the most common presenting clinical sign. Thoracic radiographs usually show a cranial mediastinal mass. Lymphoma is the main differential diagnosis. A definitive diagnosis may be made by closed biopsy but is more likely to be confirmed by thoracotomy. Thymomas may be completely contained within the thymic capsule or may spread by local invasion or metastasis. A staging system allows for an accurate prognosis and a therapeutic plan. Surgical removal of encapsulated thymomas may result in long-term survival or cure. Invasive or metastatic thymomas carry a guarded prognosis. Manifestations of the paraneoplastic syndrome complicate treatment. Adjuvant radiation and chemotherapy may be of value for advanced cases; however, adequate clinical trials have not been done in the dog.

A 67-year-old woman was admitted for intestinal pseudoobstruction associated with peripheral sensitive neuropathy. Jejunal biopsies performed during laparotomy, showed axonal degeneration and lympho-plasmocytic infiltration in myenteric plexus. High titer of seric anti-Hu antibodies suggested a paraneoplastic syndrome. Thoracic CT scan showed mediastinal lymph nodes. Their histological examination confirmed the diagnosis of metastatic small-cell lung carcinoma. Her condition gradually deteriorated despite supportive parenteral nutrition, chemotherapy, steroids and intravenous immunoglobulins. She died 12 months after the onset of symptoms.

A 13-year old cat had 3-day duration of vomiting, lethargy, and anorexia. A complete blood count revealed a severe neutrophilia (126.9 x 10(3) cells/microl). Thoracic radiographs demonstrated a large solitary lung mass. A bone marrow aspirate documented myeloid hyperplasia. A left intercostal thoracotomy was performed and left cranial and caudal lung lobectomies were performed in order to remove the mass in its entirety. Histological diagnosis was squamous cell carcinoma of the lung. Following surgery, the severe neutrophilia began to decrease. It was in the normal range approximately 6 weeks postoperatively. The presence of a primary lung tumor combined with a mature neutrophilia with resolution following surgical resection suggests a paraneoplastic syndrome.

An 8-year-old Thoroughbred mare presented for decreased appetite, ataxia, and weakness. Abdominal ultrasound revealed a large volume of anechoic fluid along with multiple masses involving the spleen, liver, and diaphragm. Pleural fluid was identified via ultrasonography and thoracic radiography. Thoracic radiographs also identified pulmonary interstitial nodules, an undulant dorsal diaphragmatic margin and enlargement of tracheobronchial lymph nodes. Clinical signs of weakness and mild seizures were concurrent with hypoglycemic episodes. The final diagnosis was cholangiocarcinoma with extensive metastasis. Clinical signs of weakness, ataxia, and seizures were attributed to a paraneoplastic syndrome of tumor-associated hypoglycemia that has been infrequently reported in horses.
