Malignant fibrous histiocytoma (MFH) arising within a cholecystectomy incision: A cause‐and‐effect relationship is possible between previous surgery and the development of a malignant fibrous histiocytoma within the operative site

Abstract

We present a report of a patient who, after an uneventful cholecystectomy, developed an incisional mass that proved to be a malignant fibrous histiocytoma and had to be excised. Five months later, the patient developed a similar incisional mass, which was shown to be a malignant fibrous histiocytoma and again had to be excised. The rarity of such a case and the details of the patient's case history are reported. The implications of a possible relationship between previous surgery, the patient's healing response, and the development of these tumors are discussed.

Ethylene oxide sterilization of autologous bone flaps following decompressive craniectomy

“…Among the reconstruction techniques using autologous bone, the flap positioned subcutaneously in the abdominal cavity [2,20,23,38] requires a second surgical wound. This aspect, seemingly marginal, should not be underestimated because the onset of benign [9,18,32] or malignant [13,16,21,30,31,34,35,39] primary tumours from the surgical abdominal or thoracic scar is well-documented, both many years after surgery for benign lesions and after a few months for malignant ones. On the other hand, if the bone flap is kept in the subgaleal space [12,19,25] there may be undesired subcutaneous blood collections, but mainly a smaller skin surface available for brain swelling, since it is already employed in containing the craniotomy flap.…”
