Abstract
Multicentric reticulohistiocytosis is a rare non-Langerhans cell histiocytosis of unknown etiology. It is classified as multicentric because of multisystem involvement. The disease predominantly affects the skin and joints, but visceral involvement is possible. Multiple erythematous-brownish, pruritic nodules and papules on the face, hands, neck, and trunk are characteristic. It is associated with autoimmune diseases, or malignant neoplasms are seen in 20% to 30% of patients with multicentric reticulohistiocytosis. The diagnosis is based on histopathology of affected tissues. As it is an underreported disease, there is no standardized treatment. A case of multicentric reticulohistiocytosis is reported as a paraneoplastic manifestation of ductal breast cancer, being successfully treated with no recurrence after two years of follow-up. Few cases of multicentric reticulohistiocytosis associated with breast cancer have been reported in the literature.
期刊介绍:
Medwave is a peer-reviewed, biomedical and public health journal. Since its foundation in 2001 (Volume 1) it has always been an online only, open access publication that does not charge subscription or reader fees. Since January 2011 (Volume 11, Number 1), all articles are peer-reviewed. Without losing sight of the importance of evidence-based approach and methodological soundness, the journal accepts for publication articles that focus on providing updates for clinical practice, review and analysis articles on topics such as ethics, public health and health policy; clinical, social and economic health determinants; clinical and health research findings from all of the major disciplines of medicine, medical science and public health. The journal does not publish basic science manuscripts or experiments conducted on animals. Until March 2013, Medwave was publishing 11-12 numbers a year. Each issue would be posted on the homepage on day 1 of each month, except for Chile’s summer holiday when the issue would cover two months. Starting from April 2013, Medwave adopted the continuous mode of publication, which means that the copyedited accepted articles are posted on the journal’s homepage as they are ready. They are then collated in the respective issue and included in the Past Issues section.
