Abstract:
Widespread eruptive purpura, hematuria and proteinuria developed in a 56-year-old woman. A skin biopsy showed leukocytoclastic vasculitis. During a 31-month follow-up, the purpura repeatedly cleared with corticosteroid treatment only to flare with tapering of the medication. Awareness of possible cancer-associated vasculitis led us to search for an occult malignancy, and an asymptomatic lung tumor was discovered. During a 32-month observation period, after resection of a well differentiated peripheral pulmonary adenocarcinoma, the purpuric skin eruption did not recur, although steroid therapy was withheld.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
