Chylothorax associated with inflammatory carcinoma

We report a rare case of a woman with inflammatory carcinoma, an unusual type of cutaneous metastasis, arising from signet-ring cell carcinoma of the stomach, who developed chylothorax as the skin lesion progressed over the chest. No thoracoabdominal lymphadenopathy which can cause obstruction of the thoracic duct was shown by computed tomography. Although a very rare condition, inflammatory carcinoma could be a cause of non-traumatic chylothorax.
