Neurological manifestations of bronchogenic carcinoma were studied in 50 cases, 42% of whom showed neurological abnormalities with 6% having more than one type. Recurrent laryngeal nerve paralysis (20%) was the commonest, phrenic nerve paralysis (2%), paraneoplastic syndrome (12%), Pancoast's syndrome (10%) and metastatic involvement of central nervous system (4%) were other neurological manifestations. No evidence of encephalitis, motor neurone disease, myelopathy, Eaton-Lambert syndrome, myositis and drug-induced peripheral neuropathy was found in this study.

We describe a patient with bilateral orbital myositis, multiple cranial neuropathies, a sensory polyneuropathy, serum and cerebrospinal fluid paraproteins, and high-grade non-Hodgkin's lymphoma. Neurologic symptoms began more than 1 year before diagnosis of the lymphoma. Results of extraocular muscle biopsy showed extensive destruction of myofibers and granulomatous features, with no evidence of direct tumor involvement. The cranial neuropathies and orbital myositis improved with immunosuppressive therapy, while the patient's tumor progressed. We believe the orbital myositis and the multiple neurologic abnormalities were paraneoplastic effects of the lymphoma. To our knowledge, this is the first case of orbital myositis identified as a paraneoplastic syndrome.

A 54 year old waiter was referred to the hospital because of proximal muscle weakness, most pronounced in his legs, which progressed to an inability to stand or walk within weeks. Myopathy was diagnosed based on the muscle biopsy findings and myositis was ruled out by laboratory and biopsy results. Further investigations led us to exclude an endocrine cause, hypovitaminosis D, infectious myopathy or a paraneoplastic syndrome. Heteroanamnesis revealed severe alcoholism, lasting for more than 30 years. The presumed alcohol induced hepatopathy was confirmed by liver biopsy. There were no signs of an acute alcoholic myopathy, as the weakness had developed rather insidiously, there was no elevation of the CK serum level nor myoglobinuria and a type 2 fibre atrophy was found by muscle biopsy. As expected the weakness improved under abstention. Thus the final diagnosis of a chronic alcohol induced myopathy was established.

The polymyalgic syndrome may be the presenting clinical feature for several diseases such as polymyalgia rheumatica, temporal arteritis, malignancy, rheumatoid arthritis, virus infections, connective tissue diseases, and myositis. In this review we present the various diagnostic options seen from a rheumatological point of view, with emphasis on polymyalgia rheumatica, temporal arteritis and the paraneoplastic syndrome. We are of the opinion that polymyalgia rheumatica is overdiagnosed in general practice, and steroid treatment may delay diagnosis and treatment of other differential diagnosis presenting as the polymyalgic syndrome. Several recently published Norwegian epidemiological studies offer new information on various aspects of the polymyalgic syndrome, which will be discussed.

Dermatomyositis (DM) is an inflammatory myopathy characterized by a typical cutaneous rash and proximal weakness. DM results from endothelium deposition of the complement membranolytic attack complex C5b-9, followed by inflammation. It is thus possible to have cases of DM with the typical rash, but with no associated myositis--amiopathic DM. DM represents a higher risk of association with malignancy and sometimes behaves as a paraneoplastic syndrome. As DM can be the alarm sign, once diagnosed, exclusion of malignancy should be done. In this article we also discuss the treatment and prognosis of dermatomyositis, according to the literature.

Camptocormia is defined as a forced posture with a forward-bent trunk which appears during standing and sitting. It was first described in 1818 by Brodie. In the last 100 years, numerous cases were observed. A psychogenic origin was presumed in most cases. We describe four patients with typical symptoms of camptocormia who present with the clinical and electromyographical criteria of a segmental dystonia. A new classification of camptocormia is proposed including (1) the primary form, a segmental dystonia of the abdominal wall muscles and (2) secondary forms. Among other conditions (psychogenic disorder, neurosis, myopathy, myositis, Parkinson's disease, multiple-system atrophy, thoracolumbar kyphosis, paraneoplastic syndrome), camptocormia is to be considered in essential tremor. A combination of dystonia of the abdominal wall muscles and essential tremor seems possible.

Focal myositis, the much rarer clinical and pathological variant of polymyositis, is generally a benign inflammatory pseudotumor of skeletal muscle Thus far, only three cases have been reported in association with a neoplasm. We now describe a fourth case of localized gluteal myositis seen in a case of signet ring adenocarcinoma of the stomach occurring not as a paraneoplastic syndrome, as in the previously reported three cases, but as an immunoinflammatory response around metastatic cell foci in both the involved muscles and local lymphatics.

The patient is a 56-year-old Japanese woman who suffered from breast cancer and ovarian cancer at intervals of 6 years, and was also complicated by two episodes of dermatomyositis, each of which occurred simultaneously with each of two cancers. When she was 51 years old, she developed dermatomyositis for the first time 6 months after the resection of breast cancer, whose histological type was tubular adenocarcinoma. The dermatomyositis remitted without oral corticosteroids in 2 months, and the remission had continued for 6 years. However, at the age of 56, dermatomyositis abruptly recurred with a pruritic generalized rash, Gottron's papules and elevated serum CK levels. Examination for malignancy revealed an ovarian tumor, which was diagnosed as serous papillaly adenocarcinoma, and the surgery was performed. After the resection of the ovarian cancer, skin rash was improved dramatically and CK levels were normalized again without oral corticosteroids. Since there were no evidences of recurrence of the breast cancer, it was considered that each episode of dermatomyositis was associated with each of the cancers, respectively. We report this rare and interesting case to consider the etiology of cancer-associated myositis as a paraneoplastic syndrome, since the two cancers have different histological types.

Phosphaturic mesenchymal tumor is an extremely rare disease and is frequently associated with oncogenic osteomalacia showing paraneoplastic syndrome, which is characterized by phosphaturia, hypophosphatemia, normocalcemia, and decreased levels of 1,25-dihydroxyvitamin D3 associated with a tumor. A 2-year-old boy, who had a soft tissue tumor on his right thigh and previously diagnosed as myositis ossificans at 9-months-old, was presented with rachitic rosary and mildly enlarged tumor. Biochemical investigations showed hypophosphatemia, hyperphosphaturia, and an increased alkaline phosphatase level of 440 U/l (25-100 U/l), suggesting rickets, which was resistant to vitamin D dietary supplementation. We were certain of intractable rickets because of oncogenic hypophosphatemia and thus decided to excise the soft tissue mass. We observed laboratory improvement of rickets after 2 weeks. On the basis of surgical and histopathological examinations, the tumor was finally diagnosed as the phosphaturic mesenchymal tumor.

A 72-year-old woman referred to our hospital because of slowly progressive (over 2 years) muscle weakness and paresthesias of the lower limbs. On neurological examination, weakness and muscle atrophies were noted in the distal upper limbs as well as the proximal lower limbs. She had also paresthesias of the legs. The level of creatinine phosphokinase (CK) was 126 IU/l. The magnetic resonance imaging demonstrated gadolinium enhancement of the nerve roots at the L4-S2 vertebrate levels. Nerve conduction study showed decreased compound muscle action potential and motor conduction velocity of tibial and peroneal nerves. Biopsy of the left biceps brachii muscle showed variations in fiber size, endomysial mononuclear cell infiltration and the findings like a rimmed vacuole. Although almost of her findings were in accord with clinical features of inclusion body myositis, strong inflammatory cellular influences allowed us to administer corticosteroid therapy. Because her weakness was well responded to steroid therapy, polymyositis was considered as differential diagnosis. Then, further examinations were investigated to search any occult neoplasm, and detected the early gastric cancer. Total gastrectomy was performed later, and the pathological diagnosis was made as a signet-ring cell carcinoma. To our knowledge, this is the first report of systemic myositis and subacute sensory neuropathy concomitant with signet-ring cell carcinoma. These symptoms might be occurred as a result of paraneoplastic syndrome associated with satellite effects of the signet-ring cell carcinoma.
