<unk>  also known as carcinomatous<unk> , is an inflammation of the lymph vessels secondary to a malignancy.<unk>  was first discovered by Gabriel Andral, a French pathologist, in 1829. The pathogenesis of<unk>  is characterized by the tumoral spread into the lymphatics, following hematogenous seeding of the lungs. The pathogenesis is also characterized by retrograde spread into lymphatics from the mediastinal and hilar lymph nodes in the lungs. Common causes of<unk>  include breast cancer (most common), lung cancer, colon cancer, stomach cancer, prostate cancer, cervical cancer, and thyroid cancer.<unk>  is a rare disease. The prevalence of<unk>  is approximately 0.03 per 100,000 individuals worldwide.<unk>  is more commonly observed among patients aged between 40 to 49 years old. Computed tomography is the imaging modality of choice for<unk> . On CT, characteristic findings of<unk>  include subpleural nodules, thickening on the interlobar fissures, pleural effusion, and hilar and mediastinal nodal enlargement (40-50%). The mainstay therapy for<unk>  is systemic chemotherapy (chemotherapeutic regimen depends on the tumor histology).
