摘要:

ABSTRACT:The morphologic examination of neonatal subcutaneous fat necrosis is reported.Subcutaneous nodules afterprolonged labor and asphyxia appeared in the skin of the back and neck. Biopsy was performed at 16 days. The infants' general state did not change and the nodules spontaneously regressed. Light microscopically focal necroses of the subcutaneous adipose tissue were present, with granulation tissue. Electron microscopy revealed complex material replacing the necrotic fat cells. Two types of crystals could be observed: short, rectangular ones irregularly arranged and long, needle‐shaped ones, parallel or radial in arrangement. The dissolved lipid crystals were surrounded by membranes that probably arose from the necrotic fat cells. The crystals passed the cytoplasm membrane of the macrophages. Giant cells arose from macrophages, partly by fusion of the cells and partly by amitosi

摘要:

ABSTRACT:Some immunologic studies were carried out for 31 patients with pityriasis rosea. Normal levels of serum IgG and IgA but higher levels of IgM were obtained. Serum C3 values were decreased while C4 values were normal. B lymphocytes showed no difference from the controls, whereas T‐cell counts were significantly lower in the patients. The migration inhibition indices were higher in the patients than the controls. Direct immunofluorescence tests were negative in the studied three cases. The possible implication of a viral infection in the production of the reported changes was discusse

摘要:

ABSTRACT:A recent 5‐year period study of the incidence of pityriasis rosea among dermatologic outpatients was conducted at the Lagos University Teaching Hospital. Three hundred fifty‐two patients with pityriasis rosea were seen. The average annual incidence was 4.8 per 100 dermatologic patients. Women predominated by a margin of 1.2:1.0. More than 91% of the patients were between the ages of 5 and 35 years, with a peak at ages 10–14. The incidence of the disease was significantly higher in the early part of the rainy season. No declining incidence was observed over the years. A blood picture of a leukopenia with relative lymphocytosis was observed early in the disease. Ampicillin, when consumed after the onset of the eruption, made the patient with pityriasis rosea clinically

摘要:

ABSTRACT:Light and electron microscopic studies of biopsy specimens taken from five patients with pityriasis rosea revealed the most conspicuous finding to be the presence of dyskeratotic cells within the epidermis. Ultrastructurally. these cells contained an aggregation of tonofilaments, intracytoplasmic desmosomes, many vacuoles, and viral‐like particles. It is assumed that pityriasis rosea is caused by a virus to which these changes are relate
