Inflammatory pseudotumor (myoblastic tumor) of the breast: a case report and review of the literature.

Inflammatory pseudotumor of the breast is a very rare cause of breast mass. To our knowledge, only a few cases have been described in the English literature. In this case, the lesion appeared on mammography as a round high-density mass with ill-defined margins and on sonography as an irregular mass of complex echogenicity with ill-defined margins and an echogenic rim. The lesion was resected with no evidence of local recurrence after 3 years. (c) 2009 Wiley Periodicals, Inc. J Clin Ultrasound, 2010.
