An unusual cause of subcutaneous emphysema, pneumomediastinum and pneumoperitoneum.

A 62 year old female with subcutaneous emphysema, pneumomediastinum and pneumoperitoneum, was observed. Pneumothorax, however, was not present. Laparotomy revealed a large infiltrate in the left lower abdomen, which had penetrated the anterior abdominal wall. Microscopically, a recurrence of previously diagnosed vulval carcinoma was demonstrated. Despite intensive treatment the patient died two months later.
