[Pre-iliac tumor mass syndrome: An atypical rheumatoid nodule]. / Syndrome de masse tumorale pré-iliaque : un nodule rhumatoïde atypique.

Rheumatoid arthritis (RA) is a polymorphous chronic inflammatory disease that is common in general population and is responsible for the occurrence of subcutaneous or visceral rheumatoid nodules. Their typical clinical presentations and localizations do not generally pose any diagnostic or therapeutic problem. We report here an atypical fistulized presentation of an unusual iliac rheumatoid nodule in a 65-year-old female patient. The evolution was favorable without recurrence at 6 months after complete surgical resection and appropriate antibiotherapy.

Bamboo nodes associated with mixed connective tissue disease as a cause of hoarseness.

Vocal fold lesions related to autoimmune diseases are rheumatoid nodules and, to a lesser extent, bamboo nodes. Mostly transverse, they are located in the middle third of the vocal cord and exhibit a yellowish appearance. The characteristic shape of these lesions led to their name. These vocal fold deposits may interfere with the normal vibratory cycle during phonation and thus may be an unusual cause of hoarseness. We present a 43-year-old woman with known mixed connective tissue disease and a dysphonia. Laryngostroboscopy showed bamboo nodes as described above. We applied several laryngeal injections of cortisone as described previously in the literature. Since this treatment did not lead to a sufficient voice improvement, we attempted to surgically remove the deposits. After the surgery, the voice improved considerably. In all patients with rheumatic diseases who suffer from a rough, breathy, or unstable voice, a laryngostroboscopic examination should be done. If, however, a bamboo node lesion of the vocal folds is found by the laryngologists, an associated autoimmune disorder must be assumed, and adequate diagnostic procedures have to be initiated. Local laryngeal injections (1-3 times) with steroids should be the first line of therapy. In unsuccessful cases, subsequent surgery can be a useful treatment of bamboo nodes to stabilize and improve voice quality.

Fluorodeoxyglucose (FDG) uptake in pulmonary rheumatoid nodules diagnosed by video-assisted thoracic surgery lung biopsy: two case reports and a review of the literature.

Two cases of rheumatoid nodules evaluated by fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) and video-assisted thoracic surgery (VATS) biopsy are reported. The first case was that of a 44-year-old woman who presented with a cavitated nodule with intense standardized uptake values (SUVs) both in the early (max 3.4) and delayed (max 4.4) phases, suggesting malignancy. However, after VATS biopsy, she was diagnosed as having a rheumatoid nodule with vasculitis. The second case was that of a 74-year-old woman admitted with bilateral lung nodules, two of which showed intense early (max 2.2) and delayed (max 6.0) phase SUVs, and mild early (max 0.6) and delayed (max 0.9) phase SUVs. These two nodules were finally proven to be a lung cancer and rheumatoid nodule without vasculitis, respectively. These cases show that rheumatoid nodules with an enhanced inflammatory process, such as vasculitis, can appear false-positive for malignancy on FDG-PET/CT scan images.

Rheumatoid nodule presenting as Morton's neuroma.

Among 101 feet that presented with symptoms and signs similar to Morton's neuroma, intermetatarsal rheumatoid nodules were found in five feet (three patients). Two patients had bilateral involvement. Histology of the excised tissue showed the presence of a rheumatoid nodule and Morton's neuroma in four feet and a rheumatoid nodule with unremarkable nerve bundles in one. A rheumatoid nodule can coexist with Morton's neuroma, as seen in our patients, and the presentation is often similar to that of a Morton's neuroma. Our patients were rendered asymptomatic with surgical treatment and went on to have appropriate management of rheumatoid arthritis. Rheumatoid nodule should be considered in the differential diagnosis of Morton's neuroma in not only rheumatoid arthritis patients but also asymptomatic patients who have never been tested for rheumatoid antibodies.

Collision Lesions of Calcifying Pseudoneoplasm of the Neuraxis and Rheumatoid Nodules: A Case Report With New Pathogenic Insights.

Calcifying pseudoneoplasm of the neuraxis (CAPNON) is a rare tumor-like lesion with unclear pathogenesis. Collision lesions of CAPNONs with neoplasms are occasionally reported. In this article, we report the first case of collision lesions between CAPNON and rheumatoid nodules (RNs) in a patient with systemic lupus erythematosus. The patient was a 51-year-old female who presented with lower back pain and subsequently a lower back mass over 2 years. Spinal magnetic resonance imaging demonstrated a heterogeneous, partially calcified mass centered in the L3-4 paravertebral regions. A biopsy of the mass was diagnostic of CAPNON. As the mass grew over the following 5 months, it was resected en bloc. Its pathological examination revealed collision lesions of RNs at different histopathological stages and CAPNON lesions, and transitional lesions exhibiting combined RN and CAPNON features, with immune cell infiltrates. Our findings provide new evidence for an immune-mediated reactive process and insights into the pathogenies of CAPNON.

Posterior tibial artery pseudoaneurysm identified subsequent to surgical wound dehiscence.

UNLABELLED: The development of a pseudoaneurysm of the posterior tibial artery is a rare event. In this article, we describe the case of a 63-year-old female with rheumatoid arthritis, who initially presented with a symptomatic subcutaneous nodule localized to the medial aspect of the right ankle. After excision of the subcutaneous nodule, she failed to heal the surgical wound and, eventually, the pseudoaneurysm of the posterior tibial artery was identified. It was not until after the posterior tibial artery was ligated and the pseudoaneurysm excised, that the wound finally healed. LEVEL OF CLINICAL EVIDENCE: 4.

Lumbar radiculopathy caused by extradural rheumatoid nodules. Case report.

The authors report on a 51-year-old woman with a 9-year history of rheumatoid arthritis (RA) who presented with symptomatic rheumatoid nodules in the lumbar extradural region with compression on the L-5 nerve roots bilaterally. She had also suffered from dysesthesia in the right lower leg and intermittent claudication. Magnetic resonance imaging revealed masses compressing the dural sac, and on lumbar myelography and computed tomography myelography a filling defect at L4-5 was revealed, which was compressing the dural sac posterolaterally on both sides. The masses were surgically removed. On histological examination the typical characteristics of rheumatoid nodules were found. Soon after the operation all of the patient's symptoms disappeared. There have been few reports on extradural rheumatoid nodules. Patients with RA usually complain of articular symptoms, and in fact the patient in the present study had been referred to the authors' institution for total hip arthroplasty. However, various symptoms other than those arising from articular lesions were found clinically. The authors believe that if patients with RA are also examined for extraarticular lesions, it is likely that these will be more frequently detected.

Rheumatoid nodulosis. Two cases with destructive polyarthritis after 20 years.

The term "rheumatoid nodulosis" was coined by Ginsberg in 1975 to designate a rare and distinctive form of rheumatoid disease. Anecdotal case reports suggest a benign nondestructive course, although prolonged follow-up data are usually unavailable. We describe two cases of typical rheumatoid nodulosis with follow-ups exceeding 25 years. Onset occurred at 14 and 22 years of age, respectively. Both patients presented with palindromic rheumatism, positive tests for rheumatoid factors, negative tests for other biological markers, and normal radiographs. Multiple subcutaneous nodules developed after 4 and 6 years with palindromic flares, respectively. Functional impairments and disfigurement required several surgical procedures to remove nodules. Histology was typical for rheumatoid nodules. Neither patient responded to disease-modifying anti-rheumatic drugs (gold, antimalarials, and D-penicillamine). Treatment consisted of nonsteroidal anti-inflammatory drugs combined with prednisone as needed. After 20 and 22 years of follow-up, respectively, both patients had typical rheumatoid arthritis with deformities and radiological joint destruction. In conclusion, these two cases establish that rheumatoid nodulosis can occur as a presentation of rheumatoid arthritis with a potential for severe joint damage after many years.

Aortic valve rheumatoid nodules producing clinical aortic regurgitation and a review of the literature.

The majority of cardiac involvement in rheumatoid arthritis (RA) is an incidental finding at postmortem, as less than 3% of patients with RA have clinical cardiac signs or symptoms. Most cardiac involvement in RA involves the pericardium and has been known since Charcot first described an RA patient with pericarditis in 1881. Cardiac involvement takes two different forms: non-specific inflammatory changes and specific granuloma formation. Specific rheumatoid nodules in the heart are an infrequent complication of RA. This is the first case report of a surgically excised heart valve with rheumatoid nodules. A 74-year-old RA patient with a high seropositive rheumatoid factor presented with severe aortic regurgitation and underwent a valve replacement. The native aortic valve showed significant stenosis with multiple, classic rheumatoid nodules.

A rare case of embolizing cardiac tumor: rheumatoid nodule of the mitral valve.

We report the case of a 65-year-old woman with rheumatoid arthritis who was admitted with a stroke. Echocardiographic examination revealed a multilobule, highly mobile tumor on the posterior leaflet of the mitral valve. Surgical exploration showed a tumor infiltrating the valve, the annulus, and the adjacent left ventricular wall, which required complete valve resection. Histologic study demonstrated typical characteristics of a rheumatoid nodule.

A giant rheumatoid nodule.

Subcutaneous rheumatoid nodules occur commonly in advanced cases of rheumatoid arthritis and are the most common extra-articular lesion of this disease. We present a case of a very unusual giant rheumatoid nodule that developed on the lateral side of a knee. The case was devoid of systemic symptoms of arthritis and the lesion was limited to a rheumatoid nodule. The nodule was successfully treated by surgical excision. However, other new nodules developed in her hand. Her clinical course has not been satisfactory.

Rheumatoid nodules of the larynx.

Two unique cases of rheumatoid nodules affecting the larynx are reported. These subcutaneous nodules represent localized laryngeal involvement from autoimmune disorders. The otolaryngologist should be aware of these possibilities as part of the differential diagnosis in the workup of dysphonia.

A case of rheumatoid nodulosis successfully treated with surgery.

We report the case of a 76 year-old male with multiple subcutaneous nodules, but without joint symptoms or deformities, who was diagnosed histopathologically with rheumatoid nodulosis after resection of the nodules. Rheumatoid nodulosis is a disease characterized by multiple subcutaneous nodules that are histopathologically similar to rheumatoid nodules, a high titer of rheumatoid factor, and radiologically detectable cystic bone lesions, but with none or few of the systemic manifestations orjoint activity of rheumatoid arthritis (RA). It is considered to be a benign variant of RA. This rare disease must be considered when a case of multiple subcutaneous nodules is encountered, even in aged males withoutjoint symptoms or deformities.

Rheumatoid nodule of the nasal septum.

Necrotizing granulomatous nodules are a common feature in patients with rheumatoid disease, affecting 20 per cent of seropositive patients. Although most commonly found subcutaneously at points of pressure, these nodules may occur in the connective tissues elsewhere in the body. In the upper aerodigestive tract, nodules have been described in diverse locations, but commonly in the trachea, larynx and the ear. We present the first reported case of a rheumatoid nodule affecting the nasal septum.

Surgery of the elbow joint in rheumatoid arthritis.

A review is made of the literature of the mechanics of the elbow joint and the types of operations available. It is clear that the elbow is a complex joint and that in patients with rheumatoid arthritis destruction and disability occurs relatively late in the disease. Of the operations available, synovectomy and excision of the radial head are best done early in order to obtain the movement of supination and pronation. Total elbow replacement, particularly the unconstrained type is producing encouraging results and seems rational in view of the structure of the elbow. However it is early days in the design of these prostheses and the clear message is that the patients need full assessment in the light of their other joints involved.

The management of rheumatoid nodules.

Rheumatoid nodules are present in approximately 25% of patients with seropositive rheumatoid arthritis (RA) and are the most common extra-articular lesions of this disease. Current methods of treatment include a variety of antirheumatic agents, surgical excision, or observation. Treatment options for the rheumatoid nodule are limited, due in part to the highly variable nature of the nodule. This series describes 4 seropositive RA patients, all with extensive rheumatoid nodules. Three were successfully treated by surgical excision, and 1 was successfully treated with conservative management. Surgical treatment is effective. Indications include local pain, nerve compression, limited range of motion, erosion, and infection.
