Soft tissue metastases are an uncommon presenting feature for primary solid tumours. This case highlights a rare presentation in which a soft tissue mass is the first clinical manifestation of a widespread disseminated malignancy of the esophagus. A 73-year-old woman presented with a soft swelling in the left upper quadrant of the abdomen arising from the anterior abdominal wall, suspicious of liposarcoma.

Have the organisms that cause breast abscess changed with time?--Implications for appropriate antibiotic usage in primary and secondary care.

Many patients with breast abscess are managed in primary care. Knowledge of current trends in the bacteriology is valuable in informing antibiotic choices. This study reviews bacterial cultures of a large series of breast abscesses to determine whether there has been a change in the causative organisms during the era of increasing methicillin-resistant Staphylococcus aureus (MRSA).

The nuclear BAG-1 isoform, BAG-1L, enhances oestrogen-dependent transcription.

BAG-1 is a multifunctional protein that interacts with a wide range of cellular targets including heat-shock proteins and some nuclear hormone receptors. BAG-1 exists as three major isoforms, BAG-1L, BAG-1M and BAG-1S. BAG-1L contains a nuclear localization signal, which is not present in the other isoforms, and is predominantly localized in the cell nucleus.
