  • Large B-cell lymphoma of the leg in a patient with multiple malignant tumours.
  • 2003
  • Ingår i: Acta dermato-venereologica. - : Medical Journals Sweden AB. - 0001-5555. ; 83:5, s. 354-7

    • A patient who had primary gastric B-cell non-Hodgkin's lymphoma, invasive ductal breast cancer and a basocellular carcinoma of the forehead in her medical history was studied. Three years after polychemotherapy and irradiation of the breast cancer, a rapidly enlarging, ulcerated violaceous tumour developed on the patient's left leg. The tumour was identified by the histopathological, immunohistochemical and immunoglobulin gene rearrangement analyses as a cutaneous large B-cell lymphoma. No signs of extracutaneous involvement were detectable. Despite surgical excision, interferon-alpha2b treatment and chlorambucil + prednisone chemotherapy, a relapse occurred in the previously affected site, whereafter the patient received radiotherapy. She was lost to follow-up, and died approximately 14 months after the surgical intervention without autopsy. We discuss the clinical and histologic features and outcome of the large B-cell lymphoma of the leg, its coincidence with other diseases, and the uncommon occurrence of primary multiple malignant tumours.

  • [New aspects in the classification of cutaneous lymphomas]. : Szemléletváltozás a kután lymphomák klasszifikációjában.
  • 2001
  • Ingår i: Orvosi hetilap. - 0030-6002. ; 142:8, s. 393-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Authors discuss the classification of primary cutaneous lymphomas created by the Cutaneous Lymphoma Study Group of the European Organization for Research and Treatment of Cancer (EORTC) in 1996, which is based on the clinical, histological, immunohistochemical and genetic features of cutaneous lymphomas. Unlike the previous histologic classifications it contains well-defined disease entities characterized by their clinical and histological picture, clinical outcome, behaviour and therapeutic response. This classification does not use the term of low grade or high grade lymphoma, but introduces the indolent, aggressive and provisional subgroups in the T-cell lymphomas, and indolent, intermediate and provisional subgroups in the B-cell group. Authors demonstrate the EORTC classification by their own cases calling the attention to the clinical and therapeutic difference between nodal and extranodal lymphomas, and discuss the up-to-date therapeutic possibilities.

  • Immunohistochemical examination of P-cadherin in bullous and acantholytic skin diseases.
  • 2004
  • Ingår i: Acta dermato-venereologica. - : Medical Journals Sweden AB. - 0001-5555. ; 84:2, s. 116-9
  • Tidskriftsartikel (refereegranskat)abstract
    • Autoimmune blistering diseases (pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, dermatitis herpetiformis) and certain genodermatoses with acantholysis (Darier-disease, Hailey-Hailey disease) have different aetiological factors, but all result in bulla formation and/or in acantholysis. Cadherins are Ca++-dependent cell-cell adhesion molecules which play an important role in the cellular connection between normal cells. P-cadherin is involved in the selective adhesion of epidermal cells, and is expressed only on the surfaces of the two basal layers. We examined the expression of P-cadherin in some autoimmune bullous skin diseases and Darier's disease using immunohistochemistry and found P-cadherin to be strongly upregulated. We believe the upregulation is compensatory to the primary pathophysiological events in the various bullous dermatoses.

  • [Immunohistochemical study of P-cadherin in breast cancer]. : P-cadherin immunhisztokémiai vizsgálata emlórákokban.
  • 2002

    • Cell adhesion molecules play a significant role in the cellular connection of normal cells. The cadherins are believed to act as tumour suppressors, and their altered expression and function have been associated with tumour development.The authors examined the expression of a Ca++ dependent intercellular adhesion molecule, P-cadherin using an immunohistochemical method in 69 surgically resected breast carcinomas.P-cadherin was detected in 30 cases (43.5%, cytoplasmic and/or membrane staining). The expression of P-cadherin was independent of tumour size and lymph node status, but correlated with a high tumour grade (grade III). In contrast, expression of E-cadherin correlated with lower tumour grade (grade I-II). P-cadherin expression was not detected in invasive lobular carcinomas.In general, P-cadherin was expressed at a lower frequency compared to E-cadherin, alpha-, and beta-catenin. These results suggest that an inverse relationship may exist between E- and P-cadherin in relation to grade, and that the expression of P-cadherin may be a marker of aggressiveness.

  • P-cadherin as a marker in the differential diagnosis of breast lesions.
  • 2003
  • Ingår i: Journal of clinical pathology. - : BMJ. - 0021-9746. ; 56:2, s. 139-41
  • Tidskriftsartikel (refereegranskat)abstract
    • To assess the value of the calcium dependent cell adhesion molecule P-cadherin as a myoepithelial marker in the differential diagnosis of benign and malignant breast lesions.Immunohistochemical analysis of normal breast, sclerotic breast lesions, tubular carcinomas, and ductal carcinoma in situ using a P-cadherin specific antibody and comparison with smooth muscle actin.All myoepithelial cells in normal breast ducts, ductules, and lobules and sclerotic lesions showed strong staining for P-cadherin. There was no staining of tubular carcinomas; myoepithelial cells were demonstrated around in situ carcinomas. Weaker reactivity was seen in a proportion of cells in some hyperplasias and in situ carcinomas. This weak reactivity in these tissues was not seen for smooth muscle actin but in radial scars, tubular carcinomas, and ductal carcinoma in situ staining of stromal cells caused difficulties in the identification of myoepithelial cells.P-cadherin is a useful marker in the differential diagnosis of breast lesions.
