We report a case of dermatomyositis (DM) associated with invasive thymoma in a 22-year-old woman who was admitted to our hospital complaining of dyspnea which required ventilation support. The reddened elevated scaly eruptions were prominent over the extensor surfaces. Chest X-ray and computed tomography showed mediastinal masses, which were diagnosed as mixed type thymoma. Muscle and skin biopsy specimens were compatible with DM. She was treated with methylprednisolone pulse therapy followed by extended removal of the anterior mediastinal tumor and subsequent radiotherapy. She has had a good clinical course without recurrence of thymoma or DM for more than 3 years. The role of thymoma in the development of DM is discussed.

We report two Japanese patients with dermatomyositis whose serum hyaluronate levels were correlated with their disease activities. The diagnosis of one patient was primary idiopathic dermatomyositis, and that of the second patient was dermatomyositis associated with neoplasia. The serum hyaluronate level of the former patient was decreased by systemic corticosteroid therapy, and that of the latter patient decreased following the surgical resection of mammary carcinoma and subsequent chemotherapy. The disease activity of each patient was greatly improved after these therapies. The longitudinal measurement of serum hyaluronate concentration may be useful to estimate the disease activity of patients with dermatomyositis whose initial serum levels of hyaluronate are elevated.

Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) is a rare lymphoproliferative disorder that often progresses to high grade T cell lymphoma. We describe a 63-year-old woman with longstanding seropositive rheumatoid arthritis who developed fever, cutaneous findings of dermatomyositis, a diffuse pruritic maculopapular rash, enlarged lymph nodes, polyclonal elevated serum gammaglobulins, and an IgG lambda paraprotein. Lymph node biopsies yielded tissue with characteristic changes of AILD and T cell lymphoma. Interleukin 6 (IL-6) was present during the early, active phase of disease, and circulating IL-6 and IL-2 were detected one month before tumor recurrence. Two years after AILD and T cell lymphoma were diagnosed, she developed a B cell lymphoma that involved the oropharynx.

Inflammatory pseudotumor (IPT) is a rare pulmonary tumor of uncertain etiology that usually presents as an asymptomatic radiographic finding. We describe a case of pulmonary IPT presenting as dermatomyositis with complete resolution following surgical resection.

Dermatomyositis, an inflammatory muscle disease probably related to dysimmunity, is associated with character skin eruptions. Dermatomyositis is often associated with cancer (15 to 40% of cases depending on the series). All histological types and all cancer localizations observed in the general population can be associated with dermatomyositis. We report the case of a patient with dermatomyositis who developed small-cell lung cancer. There have been few descriptions of this association in the literature. Certain clinical features of dermatomyositis would be predictive of its paraneoplastic nature. Prognosis is very poor. Treatment is basically dictated by the underlying neoplasia.

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.

A 52-year-old Japanese woman developed dermatomyositis. She had undergone a standard radical mastectomy for left breast cancer 21 years earlier. Though no physical sign of recurrent breast cancer appeared clinically, levels of tumor markers were abnormally elevated. Therefore, tamoxifen and CAF therapy were given. Further, the clinical course of dermatomyositis almost paralleled the level of serum tumor markers and the clinical course of her recurrent breast cancer. These markers were useful for detecting the recurrence, following the metastatic disease, and monitoring her response to therapy.

A 59-year-old man was admitted presenting systemic rash and muscle weakness. He was diagnosed to have dermatomyositis and a check was made for internal malignancy. Gastrointestinal endoscopy revealed a Borrmann type II tumor on the middle body of the stomach. Biopsy specimens showed a well differentiated adenocarcinoma, and total gastrectomy was performed. The final diagnosis was moderately differentiated adenocarcinoma invading into the proper muscular layer, with metastases to regional lymph nodes. Most of the neoplastic cells were shown to be positive for Epstein-Barr virus by means of EBV-encoded RNA in situ hybridization. The symptoms of dermatomyositis disappeared completely after surgery.

A 42-year-old man with dermatomyositis presented with right-upper-quadrant dull pain and normal blood pressure for 10 days. Abdominal ultrasonography, abdominal computed tomography, and angiography revealed a retroperitoneal tumor with direct invasion to the liver and the diaphragm. The diagnosis of nonfunctioning malignant pheochromocytoma was made on the basis of clinical evidence. The tumor was removed en bloc with part of the diaphragm, the right lobe of the liver, the right adrenal gland, and the right kidney. Pathologic examination with immunohistochemical staining revealed a malignant pheochromocytoma growing exophytically from the right adrenal gland and invading the right lobe of the liver and the diaphragm. The postoperative course has been uneventful and no recurrence has been noted over a 6-month follow-up period.

Dermatomyositis is associated with malignancy in approximately 20-25% of cases. The most common associated cancers are ovarian, lung, pancreatic, stomach, colon and non-Hodgkin's lymphoma. Nasopharyngeal cancer is not common in the Caucasian population; however, there is a much higher incidence in Asian patients. Radiotherapy is the mainstay of treatment for early nasopharyngeal cancer, but combination chemoradiotherapy is becoming more common for patients with advanced disease since the Intergroup trial 0099 demonstrated improved progression-free survival and overall survival for chemoradiotherapy. Increasingly, the cytotoxic agent amifostine is being used prior to radiotherapy in an attempt to decrease associated morbidities. Amifostine has been found to significantly decrease acute and chronic xerostomia but not mucositis. It appears to be selectively protective to salivary glands and kidneys without being tumor protective. The most common side effects associated with amifostine are nausea, vomiting, hypotension, hypocalcemia and allergic reactions. We describe the case of a man with dermatomyositis and stage IV nasopharyngeal cancer treated with chemoradiotherapy and s.c. amifostine. The patient suffered a life-threatening anaphylactoid reaction to amifostine.
