Pelvic alveolar rhabdomyosarcoma in a young adult.

Rhabdomyosarcomas are soft-tissue tumors, rare in adults. Accounting for nearly 5% of childhood cancers, they represent less than 0.03% of adult malignancies (1, 2). Three different subtypes of rhabdomyosarcoma have been described (embryonal, alveolar and pleomorphic), making up approximately 50%, 30%, and 20% of the cases, respectively (3). Although the definitive diagnosis is made pathologically, some distinguishing features among these subtypes, and between rhabdomyosarcomas and other soft-tissue tumors, can be suggested on MRI and CT. We present an interesting case of a 20-year-old female with a locally aggressive pelvic alveolar rhabdomyosarcoma. While the prognosis has improved with newer treatment techniques, overall survival rates remain poor. Our case study presents typical features of a rare disease, which can often present a diagnostic dilemma for clinicians.

Mammary duct ectasia in a man with liver disease, end stage renal failure, and adjacent arteriovenous fistula.

Mammary duct ectasia is a rare finding in males. We report a case of mammary duct ectasia in a 58 year old male with liver failure and end stage renal failure. We discuss radiology findings of mammary duct ectasia as well as potential risk factors and management options for symptomatic male mammary duct ectasia.
