Purpose We developed a new approach to visualize skin Langerhans cells by in vivo fluorescence imaging in nonhuman primates. Procedures Macaques were intradermally injected with a monoclonal, fluorescently labeled antibody against HLA-DR molecule and were imaged for up to 5 days by fibered confocal microscopy (FCFM). Results The network of skin Langerhans cells was visualized by in vivo fib...

Langerhans' cell histiocytosis summarizes a spectrum of diseases on the basis of histogenetic criteria. These are characterized by an accumulation of cells with Langerhans' cell phenotype in one or multiple organs. Up to 50% of patients with either single or multi-organ manifestation of Langerhans' cell histiocytosis initially present with cutaneous symptoms. Nevertheless, cutaneous Langerhans'...

Langerhans' cells were observed to migrate into chemically injured corneal epithelium of pigmented and albino guinea pigs in substantial numbers. Whereas the migration of Langerhans' cells was a regular occurrence in both pigmented and nonpigmented animals, the migration of melanocytes occurred in only a portion of the pigmented animals and in fewer numbers. These observations may have signific...

Langerhans' cell histiocytosis of the lung can be part of a multisystem disorder or an isolated disorder. Ninety percent of adult patients with Langerhans' cell histiocytosis of the lung are smokers. This article reports a case of Langerhans' cell histiocytosis presenting with haemoptysis. The diagnostic signs on chest X-ray, high-resolution computed tomography, and histology are highlighted, f...

the occurrence of langerhans cell histiocytosis (lch) in a patient with lymphoma is an indication of a probable relationship between them. the two conditions have similarities both clinically and histopathologically. occurrence of these two conditions in the same patient, particularly not simultaneously, is rare. according to different management and treatment of these conditions, exact histopa...

Langerhans’ cell histiocytosis may cause irreversible respiratory failure due to progressive destruction of lung parenchyma and widespread cystic change. Transplantation oVers a therapeutic option. A case is described of recurrence of Langerhans’ cell histiocytosis which was associated with deterioration in lung function four years following bilateral lung transplantation. Patients transplanted...

isolation of rat islets of langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of hanks' solution into the common bile duct. the identification of the islets was done by techniques including the use of a stereomicroscope against a black background. vital staining was done by an injection of neutral red solution through ...

Langerhans’ cell histiocytosis presenting as a parotid gland mass is extremely rare. We report a case of Langerhans’ cell histiocytosis in the parotid gland that occurred in a 34-year-old Korean male. The patient underwent parotidectomy followed by adjuvant chemotherapy. There has been no evidence of local recurrence or disease progression during 20 months after the lesion was first diagnosed. ...

1. Hypertrophy of the islands of Langerhans occurs in two forms: (1) the simple type which is nothing more than an increase in size of preexisting islands; and (2) the columnar type, in which the islands are composed of anastomosing columns of cylindrical cells. 2. Regeneration of the islands of Langerhans takes place by means of a budding off of columnar cells from the ducts. The process is an...
