RESUMO
Histologically, Kikuchi-Fujimoto disease (KFD) is a necrotising, self-limiting lymphadenitis. It typically affects the lymph nodes of the neck and it is often accompanied by a high fever. The present paper documents the case of a 28-year old male carrier of KFD. From the x-ray images, the KFD clinically appeared to be a submandibular salivary gland tumor. An ultrasound study led us to believe that it was more likely a branchial cyst. Malignant lymphoma can be mistaken for KFD, thus the diagnosis must be precise and the differentiation is crucial.

Tumours of the renal pelvis are usually urothelial carcinomas. The benign tumors are extremely rare. Fibroepithelial polyps are the most common mesodermal tumors of the upper urinary tract. They are found most commonly in the ureter but several have been reported in the renal pelvis. Patients usually present with pain and less commonly hematuria. Grossly, these polypoid structures are smooth nodules or filiform projections varying is size from a few millimeters to several centimetres. Histologically, they consist of a thick fibrous stalk with numerous vascular channels covered by a layer of normal or hyperplastic transitional epithelium. The etiology of these tumors is unknown but congenital, obstruction, allergy and trauma have been implicated. Conservative treatment is recommended when the diagnosis is certain. To our knowledge, this is the first report of fibroepithelial polyp of the renal pelvis in a patient with horseshoe kidney.

Paragangliomas are rare tumours of the bladder accounting for 0.06% of all vesical tumours. This paper reports one case of vesical paraganglioma in a young female patient that has the singularity of being associated to melanin pigmentation. A review is made of cases treated in Spain, adding some comments on the signs and symptoms presented, as well as the diagnostic and therapeutical methods used in this unusual condition.

Amyloidosis as a complication of patients afflicted with multiple myeloma only arose in 15% of the cases. The articular localization is particularly rare, the clinical findings being similar to rheumatoid arthritis. A case of amyloid arthritis associated to Bence-Jones myeloma, kappa type, is presented and the literature is reviewed.
