ANTECEDENTES: Estudiamos las características inmunopatològicas de 5 casos de necrólisis epidérmica tóxica utilizando un amplio panel de anticuerpos. OSERVACIONES: El patrón y grado del infiltrado celular inflamatorio varió dependiendo del estado de la enfermedad. La principal característica constante fue la importante implicación de la línea monocito-macrófago, incluyendo dendrocitos factor XIIIa+ HLA-DR+ y macrófagos CD68+ Mac 387+, antes y durante la necrosis epidérmica. El número de linfocitos CD4+ y CD8+ era comparativamente reducido. Ello se asociaba con un denso marcaje para el factor de necrosis tumoral alfa en la epidermis. CONCLUSIONES: Las células de estirpe monocito-macrófago superan en nùmero ampliamente a los linfocitos en las lesiones de la necrólisis epidérmica tóxica. El factor de necrosis tumoral alfa es problablemente una de las citocinas principales responsables de la necrosis. [less ▲]

Acquired persistent atypical lentigines are pigmentary lesions that are unusual both clinically and microscopically. They occur in young adults with photosensitive skin using 5-methoxypsoralen-containing sunscreens during sunbathing. Their biologic behavior is benign, but there are grounds for concern regarding the carcinogenic risk in these patients. [less ▲]

Ninety-four cervical biopsies from normal tissue to high-grade squamous intraepithelial lesion (SILs) were examined for the presence of intraepithelial Langerhans' cells and subpopulations of stromal macrophages/dendrocytes by immunohistochemistry using anti-S100, -L1, -CD68 and -factor XIIIa antibodies. Human papillomavirus (HPV) detection was performed in all cases by using first a mixture of DNA probes for 14 HPV types commonly found in anogenital biopsies at low stringency conditions (Tm -40 degrees C) and by reanalyzing the tissues at high stringency (Tm -10 degrees C) with HPV 6/11, 16/18 and 31/33/35 biotinylated probe cocktails and individual digoxigenin-labelled probes. SILs and metaplastic tissues were significantly associated with a depletion of S100-positive intraepithelial Langerhans' cells when compared with normal epithelium. In contrast, there was a significant increase in L1-positive stromal macrophages in SIL biopsies compared with normal or metaplastic cervix. A significantly higher density of CD68-positive macrophages was also observed in high-grade SILs compared with normal or metaplastic biopsies and with low-grade SILs. The density of factor XIIIa-positive dendrocytes was found to be higher in SILs compared with metaplastic tissues and in high-grade SILs when compared with normal cervical biopsies. No specific relationship was found between the densities of these cells and the HPV type detected in SILs separated into low grade and high grade. The significance of this inverse modulation of intraepithelial Langerhans' cells and stromal macrophages/dendrocytes in normal and SIL biopsies is discussed in relation to HPV infection and malignant transformation.

BACKGROUND: We studied the immunopathologic characteristics of five cases of toxic epidermal necrolysis by using a large panel of antibodies. OBSERVATIONS: The pattern and amount of the inflammatory cell infiltrate varied according to the stage of the disease. The main constant feature was the prominent involvement of the monocyte-macrophage lineage, including factor XIIIa+HLA-DR+ dendrocytes and CD68+ Mac 387+ macrophages, before and during the epidermal necrosis. The number of CD4+ and CD8+ lymphocytes was comparatively small. This was associated with a dense labeling of the epidermis for tumor necrosis factor alpha. CONCLUSIONS: Cells of the monocyte-macrophage lineage largely outnumber lymphocytes in the lesions of toxic epidermal necrolysis. Tumor necrosis factor alpha is likely a major cytokine that is responsible for necrosis. [less ▲]

The fibroblast-like cell population of the dermis is heterogeneous. The name "fibroblast" appears to be out-dated and should be replaced by terms reflecting with precision the immunophenotype of the cells. Among them, dendrocytes type I (Factor XIIIa - positive) and dendrocytes type II (CD34 - positive) are involved in a wealth of pathologic conditions. [less ▲]

L'évaluation de l'érythème est difficile et souvent aléatoire en clinique. Afin d'étudier la couleur des téguments, la colorimétrie est proposée depuis quelques années. Elle permet plus de rigueur. En tous cas, elle permet d'aligner des chiffres dont les variations peuvent être étudiées dans le temps. Le présent travail a permis de tester, de "calibrer" la méthodologie colorimétrique dans le domaine de l'érythème cutané. D'une part, l'effet vasodilatateur (érythémateux) de l'histamine, de l'autre, le blanchiment induit par l'application de topiques corticoïdes et phytopharmaceutiques ont été mesurés et discutés.

Immunohistochemical and electron microscopic studies support a Schwann cell origin for most of the granular-cell tumors of the skin. We studied 9 granular-cell tumors by immunohistochemistry, using antibodies to CD68, S-100 proteins, factor XIIIa, L1 antigen, desmin and vimentin. The CD68 monocyte-macrophage-associated lysosomal antigen was expressed in granular cells which however had no Mac 387 reactivity. The 'satellite fibroblasts' were factor XIIIa-positive similarly to dendrocytes and perineurial cells. Our study reveals the lack of specificity of CD68 antibody to identify macrophages. It also presents granular cell tumor of the skin as an exception in the group of schwannomas by the presence of factor XIIIa-positive cells inside the neoplasm. [less ▲]

On connaît actuellement une soixantaine de papillomavirus humains. Ils sont responsables des verrues, des condylomes, de papillomes ainsi que de lésions maculeuses paucisymptomatiques. Certaines tumeux épithéliales, localement invasices ou franchement malignes sont également le reflet d'une infection par certains de ces papillomavirus. Nous présentons une brève revue des méthodes cliniques et histologiques qui peuvent être mises en oeuvre pour le dépistage et l'identification de ces atteintes virales. [less ▲]

La connaissance du système immunitaire cutané a beaucoup progressé durant les dernières années. Considérée auparavant comme un organe passif de protection, on sait aujourd'hui que la peau est un organe immunocompétent. Le vieillissement cutané et l'exposition à la lumière ultraviolette ont une influence importante sur le système immunitaire cutané. Après une brève actualisation et description des cellules immunocompétentes de l'épiderme et du derme, nous considérerons la modulation du système immunitaire cutané liée au photovieillissement.

We have raised a polyclonal antibody to the 170-kD epidermal growth factor receptor. We found an intercellular pattern of immunoreactivity in the epidermis as well as a positivity of the cytoplasm of keratinocytes and eccrine secretory cells. In some samples, a nuclear labelling was evidenced in these type of cells. There is a close resemblance in the topographical distribution of these cells with nuclear labelling and those synthesizing DNA under phytohaemagglutinin stimulation. [less ▲]

The morphology of Aspergillus hyphae in diffuse pulmonary aspergillosis were studied by computarized image analysis. We considered as parameters the angles of the mycelia. These data were constrasted, with similar morphometric evaluations of Pseudalleschria boydii in invasive pulmonary pseudallescheriasis. A significant difference was found between the degrees of branching angles in these two fungi. Conversely, there was no significant difference between the total surface areas covered by the two fungi. The above data suggest a potential interest of morphometry in mycology. [less ▲]
