Perianal abscesses due to ingested foreign bodies.

The clinical presentation of perianal abscesses due to foreign bodies (FBs) impacted in the anal canal mimics common causes of acute anal pain. The diagnosis can be established by digital rectal examination and/or proctoscopy, but may miss the presence of an FB. Incision and drainage of the abscess, along with removal of the FB, results in immediate pain relief and cure. Impacted FB must not be overlooked as an unusual cause of perianal abscess. One case of perianal abscesses due to FB impacted in the anal canal is reported.

Concurrent bilateral renal angiomyolipoma and renal cell carcinoma in a patient with tuberous sclerosis complex.

Renal angiomyolipomas (AMLs) are often associated with tuberous sclerosis. These tumors are predominantly benign, although malignant forms do exist and are known to be associated with renal cell carcinoma. This case report describes a patient with tuberous sclerosis and massive bilateral AML. Total right nephrectomy was performed; histopathologic examination revealed the coexistence of AML and clear cell renal carcinoma in the same kidney. Because differentiation between renal cell carcinoma and AML with minimal or no fat component can be difficult, an accurate diagnosis is critical in the management of renal AML.
