Abstract Although the primary purpose of periodic mammograms in screening programs is to identify lesions suspected of being carcinomas, the findings are often related to systemic (benign or malignant) diseases, rather than breast cancer. Although the involvement of breast structures in systemic diseases is unusual, it can be included in the differential diagnosis of masses, skin changes, calcifications, asymmetry, and axillary lymphadenopathy. The main diagnostic entities that can be associated with such involvement are diabetes, chronic kidney disease, heart diseases, connective tissue diseases, HIV infection, lymphoma, ...

In reviewing cutaneous manifestations of various hematologic malignancies, the authors focus on secondary cutaneous lymphomas and cutaneous manifestations of histiocyte disorders. Secondary cutaneous lymphomas are defined as skin lesions that develop secondary to infiltration by systemic lymphomas with predominantly extracutaneous involvement. In their review of histiocytic disorders with skin involvement, the authors focus on Langerhans cell histiocytosis and Rosai-Dorfman disease. Their review emphasizes the histology, pathophysiology, clinical presentation, prognosis, and treatments available for these diseases.

Erdheim Chester disease (ECD) is a rare, non-Langerhans cell histiocytosis characterized by widespread tissue infiltration by CD68-positive, CD1a-negative foamy histiocytes. ECD can be difficult to identify, a...

CONCLUSION: Our data support the view that single-agent treatment with an RAF inhibitor reduces disease activity but does not cure LCH. PMID: 30474648 [PubMed - as supplied by publisher]

Conclusions: Definitive histopathological diagnosis and subsequent appropriate therapy, such as steroid administration, are required when LCH lesions in the hypothalamus become progressively enlarged and new lesions appear in the brain parenchyma. PMID: 30450262 [PubMed]

Conclusions: MAPK pathway inhibitors may be a relatively safe salvage therapy for refractory systemic LCH and LCH-ND but the efficacy and durability of responses with this strategy remains to be delineated. Children with relapsed/refractory high-risk LCH who were at the highest risk of death from disease generally benefited from this strategy. Patients with longstanding neurodegenerative disease seem to have the least benefit from MAPK inhibitors. However, patients with relatively early onset neurodegenerative disease, especially without clinical manifestations, seem to have the greatest benefit. While the presence of pers...

Introduction:Langerhans cell histiocytosis (LCH) is a rare disease involving inflammatory lesions that can occur in essentially any organ of the body. LCH lesions are defined by the presence of CD1a+/CD207+ myeloid lineage cells (LCH cells), which often have mutations within the RAS/RAF/MEK/ERK pathway and constitutive activation of ERK. A range of other immune cells are also present within lesions including an enrichment of Foxp3 regulatory T cells (Tregs).The immune suppressive cytokine transforming growth factor beta (TGF-β), which is commonly produced by Foxp3 Tregs has also been detected within lesions and blood ...
