    Notes: A case of primary low cerebrospinal fluid (CSF) pressure syndrome with galactorrhea is reported. Magnetic resonance imaging demonstrated diffusely enhanced meninges, edematous brain, and enlarged pituitary gland. Coincidental enlargement of pituitary gland and edematous brain due to low CSF pressure compressed the pituitary portal system. The 1ow-perfused anterior lobe of pituitary gland would be the mechanism of galactorrhea.

    Notes: Summary Multiple facial angiofibroma are thought to be a pathognomonic and common, feature of tuberous sclerosis. In contrast, it is rare to see multiple angiofibroma limited to one side of the face. We have studied a patient with multiple angiofibroma of one cheek, in order to search for other manifestations of tuberous sclerosis and to determine the histochemical identity of the angiofibroma. No evidence of other pathology known to be associated with the tuberous sclerosis complex was uncovered. Histopathology of the unilateral lesions revealed focal fibroplasias and positive cellular staining for factor XIIIa and vimentin similar to that described for bilateral angiofibroma. We suggested that the segmental expression of tuberous sclerosis, in the form of unilateral facial angiofibroma may result from a postzygotic mutation.

    Notes: Abstract We examined 42 herpes gestationis sera with immunofluorescence of normal human skin sections, and found that anti-keratinocyte cell surface antibodies were detected specifically in 10 herpes gestationis sera. The diagnosis of these herpes gestationis cases was confirmed by detecting antibodies against the 180 kD bullous pemphigoid antigen with immunoblotting of its fusion protein. The results of immunoadsorption assay using baculoproteins of both pemphigus vulgaris and pemphigus foliaceus antigens indicated that the herpes gestalionis sera did not recognize common pemphigus antigens. Immunoblotting of human epidermal extracts and immunofluorescence of various tissues also suggested that the sera did not recognize any other desmosomal components or paraneoplastic pemphigus antigens. The significance of this reactivity is unclear. However, because no control bullous pemphigoid sera showed this reactivity, it may suggest a different pathophysiology between herpes gestationis and bullous pemphigoid.

    Notes: The follicular proximal ends of arrector pili muscles anchor the bulge areas of human hair follicles. However, the location of the ends of these muscles towards the epidermis, especially the fine points of attachment, is not fully understood. Conventional serial sections of the scalp skin of a 12-month-old infant were examined. Most of the distal ends were situated in the upper dermis. while some seemed to be in close contact with the epidermal basal layers. In vertical sections of the scalp skin of 16-week-old fetus, double immunoenzyme staining showed a close topographic correlation between the epidermal ends of the arrector pili muscles and the epidermal and dermal Merkel cells. These findings allow speculation that fetal Merkel cells participate in the induction and alignment of arrector pili muscles.

    Notes: Summary A patient with AIDS was found to have skin lesions which contained the organisms Pneumocystis carinii and Cryptococcus neoformans. Both organisms were identified using haematoxylin and eosin. Gomori methenamine silver. Giemsa and mucicarmine stains. Electron microscopy was performed and confirmed their presence. The clinical presentation, histopathology, differential diagnosis and treatment of cutaneous P. carinii and C. neoformans in AIDS is presented.

    Description / Table of Contents: Zusammenfassung Die Nagelzellen, die von den ventralen, apikalen und dorsalen Anteilen der proximalen Matrix gebildet wurden, rückten in axial-distaler Richtung vorwärts, bis sie amproximalen Verhornungspunkte zusammentrafen. Von diesem Punkte an wurden der proximalen Nagelplatte ununterbrochen Zellen von der ventralen und dorsalen Matrix und vom Nagelbett zugefügt. Bald hörte die dorsale Matrix auf, Nagelzellen zu entwickeln und wurde weiter distal in den hinteren Nagelfalz umgewandelt. Mit der differentialen Phasenkontrast-Apparatur von Zeiss-Nomarski konnte man die Teilung der proximalen Nagelplatte in eine ventrale und dorsale Hälfte erkennen. Nächst der Lunula entwickelte das Nagelbett noch eine weitere deutliche Schicht unter der proximalen ventralen Schicht. Elektronmikroskopisch zeigten alle Nagelzellen, ohne Rücksicht auf ihren Ursprung, Verhornung durch Anhäufung von Fibrillen ohne Bildung von Keratohyalinkörnern. Membrane-coating granules (MCG) entstanden in reichlicher Menge. Sie wurden abgestoßen und bildeten die intercellulßre Kittsubstanz. Das abgestoßene Material erweiterte einige der engen Membranspalten, während es gewöhnliche, klaffende (nicht-spezifische) Zellgrenzen verengte und dadurch 150–180 Å weite intercelluläre Zwischenräume bildete, nämlich dieengen Zellverkittungen. Die engen Zellverkittungen stellten den häufigsten Typ der intercellulären Anlagerung dar, wodurch die verhornten Nagelzellen zusammengehalten wurden. Die dicke Zellhülle der verhornten Zellen, nämlich dasGrenzband, wurde durch Niederschlag von dichtem Material an der protoplasmatischen Seite der Zellmembran gebildet und nicht durch die membrane-coating granules.
    Notes: Summary The nail cells produced in the ventral, apical and dorsal portions of the proximal matrix moved in axiodistal direction to meat together at theproximal point of keratinization. The proximal nail plate from this point on was added continuously by the cells from ventral matrix and nail bed. Dorsal matrix soon ceased to produce nail cells and further distally transformed into the posterior nail fold. With Zeiss-Nomarski differential interference contrast equipment, the proximal nail plate could be divided into the ventral and dorsal halves. Near the lunula the nail bed produced one more distinct layer beneath the proximal ventral layer. Electron miscroscopically all nail cells regardless of their origins were seen keratinizing by accretion of tonofibrils without formation of keratohyaline granules. Membrane-coating granules (MGG's) were produced in abundance. They were discharged and provided the intercellular cement. The discharged material widened some of the gap junctions while it tightened nonspeccific junctions to produce 150–180 Å intercellular spaces, i.e. thenarrow junctions. The narrow junctions were the most common type of intercellular junction connecting the keratinized nail cells. The thick cellular envelope of the keratinized cells, i.e. themarginal band, was formed by a precipitation of dense material on the cytoplasmic side of the plasma membranes and not by discharged MCG's.

    Notes: Abstract We have analyzed muscle biopsy specimens from polymyositis patients who are also positive for human T cell lymphotropic virus type I (HTLV-I) using both immunohistochemistry for surface antigens of lymphocytes and macrophages and in situ polymerase chain reaction for HTLV-I proviral DNA on the same sections. We found HTLV-I in CD4+ cells but not in macrophages. This finding suggests that most of the HTLV-I-containing CD4+ cells are not macrophages but lymphocytes.
