Primary angiosarcoma of the breast is a rare malignant tumor. Diagnostic breast imaging includes mammography and ultrasound, which are usually nonspecific. A 42-year-old woman with angiosarcoma of the breast is presented. Physical findings showed a hard exophytic mass in the upper part of the left breast, with skin discoloration overlaying the mass.

Combined hepatocellular carcinoma and cholangiocarcinoma (combined HCC-CC) is a rare subtype of liver cancer displaying components of both hepatocellular and cholangiocellular carcinoma. Not only are exophytic liver tumors very rare, but their diagnosis presents a challenge due to the uncertainty of the tumor origin. In this issue, we present a case of exophytic combined HCC-CC with unusual mor...

A 62-year-old female was referred to the department of medical imaging with complaints of right cervico brachialgia. MDCT examination of the cervical spine was performed. An exophytic pseudotumoral enlargement of the right posterior articular process of C6 was first suspected on the axial native scan (A, white arrow) but multiplanar reconstructions (B) clearly identified the articular nature of...

Sialadenoma papilliferum is a rare salivary gland tumor clinically resembling papilloma originating probably from the excretory duct. It is characterized by a biphasic growth pattern of exophytic squamous component and endophytic glandular component. We report a rare case of sialadenoma papilliferum in the floor of the mouth with epithelial dysplasia with pertinent review of literature. The pre...
