Case Reports
Gefitinib for a poor performance status patient with squamous cell carcinoma of the lung harboring EGFR mutation.
Recent reports have shown gefitinib, epidermal growth factor tyrosine kinase inhibitor (EGFR-TKI) induced marked improvement in ECOG performance status (PS) as first-line therapy in EGFR mutation-positive patients with extremely poor PS. EGFR mutations frequently occur in east-Asian, female, non-smoking, adenocarcinoma patients, however they are occasionally detected in patients with non-adenocarcinomas or with a heavy smoking history. We describe a case in which EGFR mutation was detected in a male, current smoker, squamous cell carcinoma (SCC) patient with PS 4, who showed a marked response to the first-line gefitinib therapy. EGFR mutational analysis is recommended even for SCC patients especially in east-Asian populations.

We herein describe the case of a 25-year-old woman who suffered from atypical familial Mediterranean fever for more than a decade. She presented with a periodic fever, abdominal pain and persistent ulcers in the terminal ileum. Colchicine was effective, and familial Mediterranean fever was diagnosed. ⋯ Infliximab was administered when colchicine treatment became ineffective. However, infliximab treatment soon became ineffective, probably because antibodies were generated against it. Therefore, etanercept treatment was started, and the patient showed an immediate response.

Behçet's disease is a chronic relapsing disease with multiple organ system involvement, including the gastrointestinal tract, which is known as intestinal Behçet's disease. Intestinal Behçet's disease is often resistant to empirical treatments such as 5-aminosalicylic acid, immunomodulators and steroids and often causes a perforation, requiring surgical resection. Therefore, intestinal lesions are considered to be a poor prognostic factor in Behçet's disease. ⋯ We herein report the case of an adult female patient with intestinal Behçet's disease who responded well to the induction therapy with infliximab, and has been maintained in remission by scheduled administration of infliximab. Her C-reactive protein level has been sustained at a negative level, and endoscopic findings revealed complete mucosal healing. Therefore, infliximab may have the potential to induce "sustained deep remission" in patients with intestinal Behçet's disease.

To evaluate the incidence and risk factors for malignancy in Japanese patients with systemic sclerosis (SSc). ⋯ Lung cancer was significantly frequent in SSc patients, which could develop on the basis of complicated ILD.

We herein describe a rare case of meningeal carcinomatosis in a 77-year-old woman who had bilateral deafness as the initial symptom of a previously undetected colon cancer malignancy. Meningeal carcinomatosis should be considered in the differential diagnosis in cases of abrupt-onset sensorineural deafness. Both MRI scans and cerebrospinal fluid evaluation are necessary diagnostic tools, and should be used in conjunction as each of these procedures could have false-negative results. This should apply even when there is no known primary malignancy.
