In 4 patients with mycosis fungoides in the praemycotic, infiltrative and tumour stage of the disease, a differentiation and functional characterization of the infiltrate cells, obtained from cell suspensions and cutaneous smears, was carried out by means of enzyme cytochemical and immunological
The coexistence of a T-cell lymphoma with a myelodysplatic syndrome seems to be exceptional. In the case reported here the diagnostic problems raised by the appearance of cutaneous nodules in a patient with chronic myeloid leukaemia (CML) were solved by histo-immunological examinations. A 70-year
BACKGROUND
The molecular basis of unilesional mycosis fungoides (MF), characterized by a solitary lesion which is clinicopathologically indistinguishable from multifocal patch/plaque MF (early MF), is unknown.
OBJECTIVE
To investigate the microRNA (miR) profile in unilesional MF distinguishing it
Because Langerhans' cells (LC) (CD1a-positive epidermal cells) have been discussed to be involved in the pathogenesis of mycosis fungoides and Sézary syndrome, the authors examined the influence of densities of Langerhans' cells and, concurrently, of other phenotypes retrospectively on survival of
A seven-year-old castrated male Yorkshire terrier dog was presented for a recurrent skin disease. Erythematous skin during the first visit progressed from multiple plaques to patch lesions and exudative erosion in the oral mucosa membrane. Biopsy samples were taken from erythematous skin and were
Cutaneous T-cell lymphomas (CTCLs) represent different subtypes of lymphoproliferative disorders with no curative therapies for the advanced forms of the disease (namely mycosis fungoides and the leukemic variant, Sézary syndrome). Molecular events leading to CTCL progression are heterogeneous,
BACKGROUND
No immunohistologic techniques are currently available to demonstrate clonality of T-cell lymphomas. Monoclonal antibodies to the variable region of the T-cell receptor (TCR) have been produced that identify minor populations of normal peripheral blood T lymphocytes.
OBJECTIVE
We
The human T-cell leukemia/lymphoma virus (HTLV) is a novel Type-C retrovirus isolated from patients with post-thymic T-cell malignancies. Thirteen patients diagnosed in the United States were identified as having antibodies to HTLV and a typical clinicopathologic syndrome characteristic of adult
This paper describes our own findings on the role of Langerhans' cells in dermatology and discusses literature data on their detection in seven different dermatoses. The skin is an integral part of immune system. During the past 30 years, increasing evidence has been accumulated that the skin
A patient with a history of "leukemia" for 19 yr and documented hairy cell (HC) leukemia for 10 yr developed mycosis fungoides and the Sézary syndrome. The manifestations of both diseases were diagnostic on clinical and pathologic grounds. Ultrastructural, immunohistochemical, and surface marker
Cantharis vesicatoria (blister beetle) is used in Chinese medicine and has been categorized as highly toxic in the Chinese pharmacopeia. In Europe, Cantharis patches have been used since ages to treat various skin-related diseases. We investigated the cytotoxicity of the Cantharis ingredient,
Plasminogen activators (PA) play an important role in cell migration and tissue degradation. Considering the strong epidermotropism of atypical mononuclear cells in histiocytosis X (HX) skin infiltrates leading to intraepidermal abscess formation, it was the purpose of this study to look for
Advances in the molecular definition of surface proteins (adhesion molecules) involved in tumor metastasis may help to explain the invasive behavior of malignant tumors, that is, the migration of tumor cells involving reversible adhesive contacts, their release in the circulation, and their
The present study sought to delineate the phenotypic heterogeneity of the human T-cell malignancies. Twenty T-cell neoplasms were investigated for reactivity with the OKT hybridoma monoclonal antibodies and expression of acid alpha-naphthyl acetate esterase (ANAE), beta-glucuronidase (BG), and acid
This study investigates the applicability of immunocytochemical techniques towards improving the cytological diagnosis of lymph node disorders. Cytocentrifuge preparations of fine needle aspirates were examined using an indirect immunoperoxidase method and the alkaline phosphatase-antialkaline
