INTRODUCTION Desmoplastic fibroblastoma (collagenous fibroma) is a recently described tumor thought to arise predominantly from subcutaneous tissue or skeletal muscle. The natural evolution of this tumor on magnetic resonance imaging has never been described, to the best of our knowledge. We herein report a case of desmoplastic fibroblastoma arising in the(More)
Enchondroma is the most common primary benign bone tumor of the hand. Chondrosarcomas in this location, however, are extremely rare. It often is difficult to make a histological distinction between benign cartilaginous tumors and low-grade chondrosarcomas, because enchondromas at this site often show histological features suggestive of malignancy. However,(More)
BS compounds, a series of new dihydropyridines, successfully overcame multidrug resistance in P388/ADR cells in vitro. These agents synergistically potentiated the cytotoxicity of Adriamycin to P388/ADR cells at a concentration of 1–2 μM, whereas they showed hardly any synergistic effect in the parental cell line (P388/S) at the same concentration. They(More)
A 30-year-old woman had suffered from recurrent and self-limiting fevers since childhood. Although she had no mutations in the exons or introns of the tumor necrosis factor (TNF) receptor superfamily member 1A gene, her clinical characteristics were consistent with those of TNF receptor-associated periodic syndrome (TRAPS). She did not respond to treatment(More)
Malignant bone tumors with epithelial differentiation are extremely rare. Only one case of primary malignant bone tumor with distinct squamous cell carcinoma and chondrosarcoma has ever been reported. Reported herein is a case of primary malignant bone tumor with distinct squamous cell carcinoma and chondrosarcoma, so-called carcinosarcoma of bone, arising(More)
To report a case of psoriasis triggered by anti-tumor necrosis factor-alpha (TNF-α) therapy in a uveitis patient with Behçet’s disease. A 34-year-old man with established Behçet’s disease was started on infliximab therapy for recurrent uveitis and showed an excellent response. After 2 years of infliximab treatment, he developed erythematous scaly plaques on(More)
From a clinicopathological conference on nine elderly patients with Epstein-Barr virus (EBV)-associated T/natural killer (NK)-cell lymphoma, we have addressed the patients' backgrounds, clinical manifestations, histopathological findings, cytogenesis, complications and prognoses. Among these elderly patients (>65 years old), seven patients had extranodal(More)
Acral lentiginous melanoma (ALM) of the sole sometimes has a hyperkeratotic appearance and mimics a pigmented wart. We report a case of an 81-year-old woman with an ALM on the left sole with hyperkeratosis. Due to its presentation it was difficult to make a correct diagnosis at the beginning. Finally we noticed several small, pigmented macules around the(More)
