The case of a 48-year-old patient is presented, suffering from persisting pain in the right lower leg for more than a year following a distortion of the ankle. The patient was known to have a history of severe asthmatic disease. Conventional X-rays showed a periostitis of the lower tibia and fibula. To exclude a malignant process, an open biopsy was performed. Neither tumor nor any histological signs of chronic inflammation were found. The patient claimed to have a similar pain in the contralateral lower leg 5 months after initial biopsy. X-rays again showed signs of a periostitis of the tibia and fibula. Furthermore, an increase in isotopes in this area was found in a performed bone scan. Diagnosis of osteoarthropathia hypertrophicans was confirmed 2 years after onset of the first symptoms. Pathogenetic variables both of the primary and secondary forms of hypertrophic osteoarthropathy (HOA) are as yet not completely clarified. Secondary hypertrophic osteoarthropathy (SHOA) may be defined as a syndrome of the long bones with clubbing of the fingers and toes, and occurs in the process of chronic lung and mediastinal disease. We conclude that HAO detection may contribute to early detection of lung disease, especially bronchopulmonary cancer, before it becomes clinically and radiographically manifest.

Malignant neoplasms are associated with a wide variety of paraneoplastic rheumatological syndromes. Among these, hypertrophic osteoarthropathy, carcinoma polyarthritis, dermatomyositis/polymyositis, and paraneoplastic vasculitis are the most frequently recognized. Other less known associations are based upon a smaller number of reported patients, and include fasciitis, panniculitis, erythema nodosum, Raynaud's syndrome, digital gangrene, erythromelalgia and lupus-like syndromes. Musculoskeletal manifestations of malignancy may coincide, follow or antedate the diagnosis of cancer, or herald its recurrence. The clinical course generally parallels that of the primary tumour, and treatment of the underlying malignancy often results in regression of the rheumatic disorder. Awareness that cancer can cause certain non-metastatic symptoms is important for early diagnosis and treatment of an occult neoplasm. Rheumatic manifestations suggesting a hidden cancer include: rapid onset of an unusual inflammatory arthritis clubbing or diffuse bone pains in a patient 50 years of age or older, chronic unexplained vasculitis, refractory fasciitis, Raynaud's syndrome unresponsive to vasodilator therapy, rapidly progressive digital gangrene or Lambert-Eaton myasthenic syndrome. Management consists of control of the underlying cancer and symptomatic treatment of the rheumatic syndrome with non-steroidal anti-inflammatory drugs or corticosteroids.

This is a case of a 70 year old male patient suffering from bilateral leg pain for 2 months. Physical examination disclosed clubbing. X-rays of the legs showed bilateral periosteal elevation with subperiosteal bone formation. 99TM-diphosphonate bone scan was negative. A search for malignancy revealed pleomorphic carcinoma of the right lung. Pain symptom disappeared 2 days after resection of the tumor. Repeated X-rays of the legs, three and a half months later showed no change and the clubbing persisted. Hence, unexplained bilateral leg pain should raise suspicion of hypertrophic osteoarthropathy, and elicit a search for secondary disease especially lung tumor. It is interesting to point out the negative bone scan and the rapid resolution of patient symptoms after resection of the tumor.

Hypertrophic osteoarthropathy (HOA) is a paraneoplastic syndrome consisting of digital clubbing, polyarthralgias, and periostosis that sometimes accompanies primary bronchogenic carcinoma and other pulmonary malignancies. We report a case of HOA as the initial manifestation of pulmonary metastases in a 42-year-old woman with malignant phyllodes tumor of the breast. Since the treatment for malignancy-associated HOA is targeted at the underlying neoplasm, it is important to make the diagnosis in a timely fashion so that appropriate therapy may be initiated without delay. HOA symptoms generally improve, as they did in our patient, if the cancer responds to treatment. The pathophysiology of HOA is poorly understood, but a role for tumor-associated humoral mediators has been postulated. The hypothesized mechanisms underlying HOA are reviewed, and evidence for a prominent role for platelet-derived growth factor in mediating this syndrome is examined. This unusual case illustrates the importance of suspecting HOA in a patient with a history of cancer who presents with otherwise unexplained polyarthralgias.

Facial pain can, on rare occasions, be the presenting symptom of lung cancer. This report describes a patient with non-metastatic lung cancer, which was associated with attacks of debilitating facial pain, presenting as cluster headache. Moreover, 32 reported cases of lung cancer-related facial pain (including the present one) are reviewed, and their clinical features are summarized. The facial pain is almost always unilateral, and is most commonly localized to the ear, the jaws, and the temporal region. The pain is frequently described as severe and aching, and may be continuous or intermittent. Aggravation and expansion of the pain, digital clubbing, increased erythrocyte sedimentation rate, and hypertrophic osteopathy, may contribute to the diagnosis. Referred pain, due to invasion or compression of the vagus nerve, as well as paraneoplastic syndrome secondary to the production of circulating humoral factors by the malignant tumor cells, is implicated in the pathophysiology of facial pain associated with non-metastatic lung cancer. Radiotherapy and tumor resection with vagotomy are very effective in aborting the facial pain. Thus, lung cancer should be included in the differential diagnosis of facial pain that is atypical and/or refractory to treatment.

Epithelioid hemangioendothelioma is a rare vascular tumor, which occurs in the lung, liver, bone, and soft tissue. Hypertrophic osteoarthropathy is a syndrome characterized by subperiosteal new bone formation, joint effusion and clubbing, and may be associated with cyanotic heart disease, chronic pulmonary disease, liver disease, and other miscellaneous diseases. The activation of endothelium and platelets has been suggested to be involved in the development of hypertrophic osteoarthropathy. We report a rare case of hypertrophic osteoarthropathy, which developed in association with hepatic epithelioid hemangioendothelioma with pulmonary metastasis. We also discuss the role of vascular endothelial growth factor in its pathogenesis.

BACKGROUND: Periostitis, usually seen on X-ray, may be diagnosed on bone scan as non-nodular cortical bone hyperactivity. Both the complete form (including clubbing, arthritis and periostitis) and the incomplete form have been described in association with chronic pulmonary disease, neoplasm, hepatopathy and inflammatory bowel disease. It is not known whether the bone scan pattern of non-nodular cortical bone hyperactivity varies with the etiology. METHODS: We conducted a retrospective study to analyze the etiologies and bone scan patterns of 115 cases of non-nodular cortical bone hyperactivity. RESULTS: Eighty percent of our patients were asymptomatic. Thirty-four percent of all cases of periostitis (all bilateral) were associated with cancer. The rate of cancer in cases of periostitis involving both lower limbs was 28.5%; it was 61.3% when both lower and upper limbs were involved. The duration of the disease was not correlated with either the distribution of periostitis or the intensity of uptake. Moreover, the intensity of uptake was not correlated with the importance of the symptomatology. Bone scan pattern (regular versus heterogenous uptake, localized versus diffuse uptake) was not correlated with the etiology. CONCLUSIONS: Bilateral upper and lower uptake should alert the clinician to the risk of association with neoplasm. Bone scan pattern and intensity of uptake are not necessarily correlated with etiology.

Inflammatory myofibroblastic tumors of the lung are rare, here, an unusual case is described. A 14-year-old boy presented with a history of weight loss and clubbing and was found to have a solitary circumscribed mass in right lower lobe treated with lobectomy. This case indicates the need for early and complete removal of the inflammatory myofibroblastic tumor of the lung.

The patient was a 39-year-old woman admitted with complaints of fever, clubbed fingers and arthralgia. A chest roentgenogram and chest computed tomographic scan revealed a mass in the left lower lobe. Transbronchial lung biopsy was performed, and a diagnosis of moderately differentiated adenocarcinoma was made. Physical examination confirmed finger clubbing in both hands. Bone scintigram showed marked accumulation of 99mTc-MDP in the long bones, bones of the elbows, and patellae. These findings yielded a diagnosis of pulmonary hypertrophic osteoarthropathy associated with primary lung cancer in young adult. The patient had fever and disturbance of gait of arthralgia on admission, and was treated with an oral non-steroidal anti-inflammation drug (NSAID). Advanced non small cell lung cancer (clinical stage T2 N3 M1, Stage IV) was then diagnosed. Gefitinib was administered after EGFR mutation was found in the tumor specimen. NSAID therapy alleviated the fever and arthralgia. After starting gefitinib and discontinuing the NSAID, She had kept a remission of rational symptom with cytoreductive effect. The abnormal findings of bone scintigrams subsequently disappeared and the patient's serum ICTP dropped.

We report a case of a 65-year-old male patient who presented with gradually worsening dyspnea over 2 years. History was significant for smoking and the absence of any hazardous occupational exposure. The clinical findings at presentation included absent breath sounds and stony dullness on the left side, with tracheal deviation contralaterally and clubbing. A chest roentgenogram showed a left-sided opacity occupying almost the entire left hemithorax. A subsequent CT scan of the chest revealed an intrathoracic, extrapulmonary lesion producing a mediastinal shift. Surgical resection of the mass was performed, and pathology, along with immunohistochemical studies positive for CD34 and negative for epithelial markers, confirmed the diagnosis of solitary fibrous tumor of the pleura (SFTP). SFTP is a rare neoplasm, and diagnosis is often difficult. Suspicion of SFTP should arise in the setting of a patient presenting with a paucity of symptoms (except in the case of an accompanying paraneoplastic syndrome), the absence of exposure to asbestos, and a large mass with sharp margins and encapsulation seen on a chest radiograph.
