Mondor's disease: a rare cause of anterior chest pain.

We report the case of a 52-year-old patient who sought a rheumatologic consultation for anterior chest pain of 2 weeks' duration. Radiology for trauma did not reveal any pathology. The laboratory findings focusing on rheumatologic diseases remained unhelpful and no abnormalities were found. After a cutaneous linear cordlike lesion at the right lateral chest wall occurred, the diagnosis of Mondor's disease could be made on the basis of clinical and histologic investigation. Because pain precedes the typical clinical manifestation, problems of diagnosis can occur in the early phase of the illness.
