We report a 73-year-old Japanese man with dermatitis herpetiformis which developed after diagnosis of anaplastic large cell lymphoma. The patient suffered fever, sweating, shivering, and multiple enlarged cervical lymph nodes. The diagnosis of anaplastic large cell lymphoma was confirmed by the histologic features of a biopsied cervical lymph node. The(More)
Nestin is an intermediate filament protein, and serves as a hair follicle stem cell and neural stem cell marker. Recent studies have suggested that nestin expression is also important for tumorigenesis. Previous reports from our laboratory have revealed that nestin is a marker of HMB-45-negative melanoma cells in dermal invasive lesions of nodular malignant(More)
Chronic leg ulcers have various causes and can be difficult to treat, although topical treatments, including basic fibroblast growth factor and PGE1, have been used. We applied an allogeneic cultured dermal substitute (CDS) to eight patients with intractable ulcers. The patients had various underlying diseases, including diabetes mellitus, systemic lupus(More)
Human papillomaviruses (HPVs) have been detected in lesions of Bowen's disease (BD) and Bowen's carcinoma (BC); the invasive tumor retains the cytological characteristics of BD. Previous reports suggest that nestin-expressing hair follicle stem cells are undifferentiated and pluripotent, and nestin expression in some tumors indicates poor differentiation(More)
A 66-year-old woman with a history of deep vein thrombosis (DVT) presented with an irregularly shaped leg ulcer surrounded by pigmentation on the left lower limb. In addition, the circumference of her left thigh had gradually increased. The ulcer did not respond to topical treatment and enlarged, therefore, she visited our hospital. Arteriography of the(More)
Nestin, a marker of neural stem cells, is expressed in the stem cells of the mouse hair follicle. The nestin-expressing hair follicle stem cells can differentiate into neurons, glia, keratocytes, smooth muscle cells and melanocytes in vitro. These pluripotent nestin-expressing stem cells are keratin 15 (K15)-negative, suggesting that they are in a(More)
