1/6. Cancer polyarthritis resembling rheumatoid arthritis as a first sign of hidden neoplasms. Report of two cases and review of the literature.Recent onset arthritis reminiscent of rheumatoid arthritis (RA) may be an early manifestation of an occult malignancy. In this report, we present two patients with cancer-associated polyarthritis. Both suffered from symmetric polyarthritis when initially visiting their physicians and did not achieve relief when treated with non-steroidal anti-rheumatic drugs (NSAIDs). In both patients, subsequent work-up led to the diagnosis of an underlying malignancy. One patient suffered from small cell lung cancer (SCLC), while the other was diagnosed with adenocarcinoma of the colon. In both, the arthritis spontaneously disappeared after successful treatment of the malignancy, i.e. chemotherapy and tumor resection, respectively. We discuss these cases in view of the existing literature, since awareness of the entity of cancer polyarthritis is necessary for its timely treatment and may potentially be life-saving.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
2/6. Rheumatoid arthritis-like syndrome: a presenting symptom of malignancy. Report of 3 cases and review of the literature.Recent onset arthritis might be an early manifestation of an occult malignancy. Three patients are described: one with carcinoma, primary site unknown; one with oat cell carcinoma of the bronchus; and one with breast cancer. The presenting symptom of their disease was polyarthritis. Two of the patients were seropositive and in two patients the arthritis regressed following the removal of the tumor. awareness of paraneoplastic arthritis, especially if its appearance is explosive or in relatively old age, should caution the physician of the possibility of a potentially curable, but hidden neoplasm.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
3/6. Metastatic umbilical carcinoma: the Sister Joseph's nodule.Metastatic umbilical carcinoma has been referred to by generations of physicians as Sister Joseph's nodule. Though not common, this characteristic lesion is important to recognize and properly evaluate. We present a case of an eighty-two-year-old woman with a Sister Joseph's nodule due to an unknown primary carcinoma, and we review the diagnostic and prognostic features of umbilical metastases.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
4/6. Lumbosacral radiculopathy secondary to L5 metastatic melanoma of unknown primary.Lumbosacral radiculopathy secondary to spinal malignancy is rare. Spinal melanoma without cutaneous manifestations is even more unusual. We present the case of a 45-year-old physician with a history of degenerative disease of lumbar spine and chronic back pain who presented with increasing back pain with right radiculopathy despite conservative management for 6 months. Computed tomography showed a destructive lesion of the L5 vertebral body. Results from a biopsy guided by computed tomography suggested neoplasm of unknown origin. The patient underwent anterior vertebrectomy with instrumentation and fusion. Surgical pathology study results showed metastatic melanoma of unknown primary. The patient had no cutaneous manifestation of the disease. This is the first reported case of radiculopathy due to melanoma metastatic to the lumbar spine. In view of the atypical presentation of our patient's malignancy, we emphasize the importance of including malignancy of lumbar spine in the differential diagnosis of progressive lower back pain with radiculopathy.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
5/6. Anterior hip pain in the adult: an algorithmic approach to diagnosis.The adult patient who complains of anterior hip pain is a dilemma frequently encountered by the primary care physician. Detailed history taking, physical examination, and plain x-ray films are indicated for the initial evaluation. Anterior hip pain is often diagnosed as musculoskeletal strain/sprain and treated with a conservative regimen represented by the acronym NICER (nonsteroidal anti-inflammatory drugs, ice, compression, elevation, and rest) with or without physical therapy. On occasion, this therapy fails to eradicate the symptoms. When these symptoms are refractory to diagnosis by conventional means, a more comprehensive evaluation of the etiology is warranted. Refractory pain is defined in the authors' practice as pain that persists after 4 weeks of initial conservative management. This subsequent evaluation includes the use of such laboratory tests as complete blood cell count with differential count, Chem 20 health profile, erythrocyte sedimentation rate, and an arthritic panel (assessment of rheumatoid factor, antinuclear antibody, c-reactive protein). Ancillary radiologic tests warranted include a nuclear bone scan, a magnetic resonance imaging scan, a computed tomography arthrogram with hip aspiration, and/or a scan of white blood cells labeled with indium 111. The test chosen depends on the etiology most suspected. A useful diagnostic algorithm for the investigation of anterior hip pain in the adult is provided. An illustrative case presentation of carcinoma of an unknown primary site presenting as anterior hip pain demonstrates the algorithm as it applies in the authors' practice.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
6/6. paraneoplastic cerebellar degeneration. Case report and literature review.paraneoplastic cerebellar degeneration (PCD) presents with acute or subacute onset of ataxia, dysarthria, and intention tremor. In patients older than 50 years, acute or subacute cerebellar degeneration is paraneoplastic in origin in 50% of cases. paraneoplastic cerebellar degeneration most often precedes a potentially curable remote malignancy. Less often, PCD occurs in a patient with a known malignancy or heralds the onset of a recurrence. The presence of specific antibodies in serum samples helps to guide identification of the occult underlying malignancy. physicians should entertain the diagnosis of PCD when older patients present with signs of cerebellar degeneration without an obvious cause. A systematic evaluation, including the selection of appropriate imaging and laboratory studies, will often enable physicians to identify the responsible cancer. However, because PCD can precede a cancer by months to years, periodic reevaluation is needed when the cancer remains occult.- - - - - - - - - - ranking = 1keywords = physician (Clic here for more details about this article) |
