    Notes: Many patients who present with patch and early plaque stage mycosis fungoides follow an indolent course and survive for many years following diagnosis. A certain subset of patients, however, have rapidly progressive disease leading to accelerated demise. We examined 21 histologic sections from initial biopsies taken from patients with stable disease and 26 from patients with rapidly progressive disease in order to evaluate the role of histology in predicting the disease course. Two or three authors examined each case and scored each of 24 histologic parameters using a previously described four-point scale with no knowledge of the patients' clinical courses. Interobserver agreement was quite high. The only histologic parameter that demonstrated statistical differences between the two groups of patients was degree of acanthosis. The degree of spongiosis, number of eosinophils, amount of hyperconvolution of dermal lymphocytes and density of the dermal infiltrate approached statistical significance but did not attain this level. All of these differences were quite small. No differences were seen for the other 19 parameters. Patients with rapidly progressive disease tended to have more acanthosis, a few more hyperconvoluted dermal lymphocytes, a slightly greater number of eosinophils and perhaps a slightly more dense dermal infiltrate than patients who had stable disease. However, as all of these changes were very slight, it appears unlikely that evaluation of any single biopsy specimen for the histologic parameters we studied is helpful in predicting the prognosis for a specific patient.

    Mycosis fungoides skin lesions contain CD8+ tumor-infiltrating lymphocytes expressing an activated, MHC-restricted cytotoxic T-lymphocyte phenotype (1994)

    Notes: In prior studies, we showed that most CD8+ cells infiltrating skin lesions of CD3+CD4+ mycosis fungoides were CD3+ T-line-age tumor-infiltrating lymphocytes (TIL) whose overall phenotype was suggestive of MHC-restricted cytotoxic T lymphocytes (CTL). However, their lack of cytotoxic-associated granzyme A mRNA suggested that they might be inactivated CTL precursors. In this study, we used single- and double-label immunohistologic techniques to assess the expression of TlA-1-reactive protein and HLA-DR by these CD8+TIL. Monoclonal antibody TIA-1 recognises a novel family of proteins expressed preferentially by cytotoxic cells, including some that lack grauzyme A. HLA-DR is a marker of T-cell activation. Single-label studies of 32 cases showed that CD8+TIL and TIA-1+ cells constituted a variable minority of the total cellular infiltrate and had a similar distribution. Double-label studies of 14 cases showed that in most instances the aggregate phenotype of the majority of CD8+TIL was CD3+TIA-1+HLA-DR+CD56−CD57−. These findings suggest that many of the CD8+TIL within skin lesions of CD3+CD4+ mycosis fungoides are activated, MHC-restricted CTL.

    EXPRESSION OF CLASS II MAJOR HISTOCOMPATIBILITY ANTIGENS BY KERATINOCYTES IN CUTANEOUS T CELL LYMPHOMA (1994)

    Notes: Background. Expression of various class II MHC antigens by lesional keratinocytes may play an important role in the pathophysiology of a wide variety of human dermatoses including cutaneous T cell lymphoma (CTCL). Nevertheless, there is relatively little information available concerning the concurrent expression of HLA-DR, -DP, and -DO class II MHC antigens in CTCL. Therefore, our aim in this study was to determine the prevalence, localization, extent, temporal sequence, and consistency of class II MHC antigen expression by lesional keratinocytes in CTCL. Methods. We used a semiquantitative immunohistologic analysis to analyze HLA-DR, -DP, and -DO. expression by lesional keratinocytes in 66 skin biopsies obtained from 39 patients with CTCL. Results. Class II MHC antigen expression by keratinocytes was observed in 77% of cases. Expression was detected on the cytoplasmic membrane and within the cytoplasm. It varied among cases from focal to confluent. There was a hierarchy of antigen expression in terms of both extent and time course. HLA-DR was expressed first and most extensively, followed by HLA-DP and then HLA-DQ. Comparative studies of multiple serial or concurrent active lesions from 13 cases indicated that the overall pattern and extent of antigen expression was relatively constant within individual patients. Conclusions. There was no apparent correlation between class II MHC antigen expression and the clinical stage of disease, the type of CTCL skin lesion, or the overall density of the lesional T cell infiltrate. The hierarchy of keratinocyte class II MHC antigen expression observed in this study paralleled that noted in earlier studies of cultured keratinocytes exposed to recombinant interferon-γin vitro. This suggests that lesional cytokine levels may be the critical factor governing class II MHC antigen expression by lesional keratinocytes in CTCL.
