摘要:

A scanning electron microscopic (SEM) study of intertrigo is presented. Marked changes of the keratinocyte surface characteristics and in the number and distribution of bacteria in the various stages of intertrigo are reported. Bacterial overgrowth was significant. This study confirms the value of SEM in the study of the skin surface and in cutaneous microbiology.

摘要:

This case report illustrates the microscopical and ultrastructural findings obtained in a case of Abrikossoff's tumor. On the basis of the light and ultrastructural data a neural histogenesis is suggested.

摘要:

In order to characterize the benign and malignant proliferation of lymphoid cells in skin, we compared surface markers and cytoplasmic organelles of cells in cutaneous lymphoid hyperplasia (CLH), lymphomatoid papulosis (LP), mycosis fungoides (MF), Sézary's syndrome (SS) and primary cutaneous malignant lymphoma (ML). The immunohistochemical study showed cells with both T‐ and B‐cell markers in CLH, LP and early MF, whereas cells with only the T‐cell marker were seen in late MF, SS and ML. T‐cells in all cutaneous lesions possessed the surface marker common to T‐cells of peripheral lymph nodes, and not that of central thymus cells. Cutaneous T‐cells contained clustered or scattered dense core granules. Although no specific organelles indicative of benign or malignant lymphoid proliferation were found, there were several ultrastructural features that could help identifying each form of cutaneous lymphoid lesions. These included clustered or scattered dense‐core granules, the variable degree of nuclear convolutions as well as dendritic arborization, and the presence or absence of 1

摘要:

A case of rudimentary polydactyly (cutaneous neuroma) on the ulnar aspect of the left fifth finger of a 38‐year‐old male was examined and the skin was studied by light and electron microscopy. In addition to a proliferation of nerve fibers and encapsulated corpuscles, normal Merkel cells were often present in the basal portion of the epidermis. It is suggested that proliferation of various neural components is the essential feature of the affected s

摘要:

A case of generalized pediculosis corporis is presented. Microscopic study of sectioned hairs stained with hematoxylin and eosin and of hairs under polarized light allowed identification of larval content and eggs. The value of microscopic examination of hairs is shown.

摘要:

The skin of a patient with giant axonal neuropathy was studied by light and electron microscopy. Enlarged melanocytes protruded into the papillary dermis. An increased number of microfilaments (100 A), which accumulated in rounded or irregular clusters was the main pathological feature. Melanosomes and melanisation were normal.A similar increase of microfilaments was seen in axons and Schwann cells of peripheral nerves, fibroblasts and endothelial cells. This suggests that this metabolic, probably inborn and genetic disorder, does not only affect the nervous system but also the whole microfilament system (cytoskeleton).
