Profuse bleeding from a pseudoaneurysm of the right superior thyroid artery after tracheostomy.

Case: A 70-year-old man was brought to our hospital emergency department with accidental thermal burns. Surgical tracheostomy was carried out on day 8 after admission, followed by several profuse bleeding episodes from the orifice. Contrast-enhanced computed tomography of the neck revealed a small nodule with arterial phase enhancement that was suspected to be a pseudoaneurysm.

Potential tumor markers of renal cell carcinoma: α-enolase for postoperative follow up, and galectin-1 and galectin-3 for primary detection.

The diagnosis of renal cell carcinoma is currently based on imaging techniques, mainly because there is no blood marker available for its detection. Thus, there is still the need for the development of novel tumor markers. We examined plasma levels of eight proteins in 15 renal cell carcinoma patients before and after surgery, and in 51 healthy controls using enzyme-linked immunosorbent assay.

[Case of bilateral renal cell carcinoma with the tumor thrombus in the inferior vena cava].

We describe a case of bilateral renal cell carcinoma with the tumor thrombus in the inferior vena cava. A 71-year-old male was admitted to our department for, careful examination of bilateral renal tumors. Abdominal computed tomography (CT) revealed bilateral solid enhanced renal masses with the tumor thrombus in the inferior vena cava (IVC) and the left renal vein.

[Cutaneous epithelioid granulomas caused by subcutaneous infusion of leuprorelin acetate: a case report].

A 73-year-old man presented with an ulcer and a subcutaneous nodule where he was receiving leuprorelin acetate injections to treat his prostatic carcinoma. Pathological findings of a skin biopsy showed many epithelioid granulomas with multinuclear giant cells, which contained small vacuoles. Recently, these lesions have been suggested to be caused by a type IV allergic response to the copolymer of lactic and glycolic acids used as a vehicle for drug administration.
