[Primary systemic amyloidosis presenting as polymyalgia rheumatica and giant cell arteritis].

Primary systemic amyloidosis or AL-amyloidosis is an uncommon disease characterized by the accumulation in vital organs of a fibrillar protein consisting of monoclonal light chains. It is a plasma-cell dyscrasia related to multiple myeloma where clonal plasma cells in the bone marrow produce immunoglobulins that are amyloidogenic. A monoclonal component is present in the serum or urine of 90% of patients. The presentation of most patients with AL amyloidosis is usually related to congestive heart failure, nephrotic syndrome o peripheral neuropathy, but there are unusual features suggesting giant cell arteritis (GCA) and polymyalgia rheumatic (PMR). Although in the majority of AL cases the plasma cells clone is small, the assumption is that the outcome of the disease is uniformly fatal (median survival 12-15 months) and treatment is analogous to those used in malignant proliferative disease. We describe a patient with AL amyloidosis who presented with manifestations of GCA and PMR, and we review the main characteristics of primary amyloidosis.

[Solitary pulmonary nodule in a patient with treated carcinoma of the renal pelvis: metastatic disease?].

OBJECTIVE: To describe a case of a solitary pulmonary nodule in a patient that had been treated for carcinoma of the renal pelvis. METHODS: A solitary pulmonary nodule was detected on the chest film of a patient that had been treated for carcinoma of the renal pelvis. The characteristics of the nodule are described and its diagnosis, with special reference to metastasis and primary pulmonary carcinoma, is discussed. RESULTS: The anatomopathological study demonstrated a chondroid hamartoma. CONCLUSIONS: A metastatic or a primary tumor is suspected when a solitary pulmonary nodule is detected in a patient that has been previously treated for urothelial carcinoma. However, other types of lesions with a more favourable outcome cannot be discarded, such as chondroid hamartoma as in the case described herein.

[Dilatation of the azygos vein: an unusual cause of pulmonary mass].

Infrahepatic interruption of the inferior cava vein, is a rare congenital anomaly, usually associated with congenital heart and abdominal diseases. The systemic venous flow is accommodated by the dilated azygos. This dilated azygos arch accounts for the right paratracheal or mediastinal mass, and may be misinterpreted as a neoplasm. We report a case with this congenital vascular anomaly, associated with another of tracheobronchial tree.

[Prostatic syndrome and pleural effusion: are they different diseases?].

OBJECTIVE: To report an uncommon association of prostate and lung cancer. METHODS: The characteristics of both tumors, their association with tumors in other sites and the time of presentation are analyzed. RESULTS: Both tumors were in the advanced stages. Metastatic carcinoma of the prostate was discarded due to the form of presentation. CONCLUSIONS: Although the association of prostate and lung cancer is uncommon, the possibility of synchronous tumors should be considered in patients with urinary and pulmonary symptoms suggestive of neoplasm. It is important to determine if the lesion is a metastasis, since the prognosis depends on the second tumor.

Leg bone pain syndrome due to cyclosporine in a renal transplant patient.

A leg bone pain syndrome of unclear etiology has been recently described in renal transplant patients receiving cyclosporine A. Herein we report a 54-year-old woman treated with cyclosporine A (CsA), corticosteroids and azathioprine who developed two months after renal transplantation severe symmetric pain with periarticular soft tissue swelling in the knees and metatarsophalangeal joints. Scintigraphy showed periarticular radionuclide activity. Clinical onset was associated with both the high dosage and with the plasma levels of CsA. Symptoms improved when the dosage of CsA was reduced and the plasma levels declined to less than 150 ng/ml.
