[Heterotopic ossification on a midline laparotomy scar after digestive surgery: etiopathogenic discussion about two cases]. / Ossification heterotopique sur cicatrice mediane abdominale apres chirurgie digestive: discussion etiopathogenique a propos de deux cas.

Heterotopic ossification (HO) is rarely seen after abdominal surgery and usually occurs after orthopedic surgery. It is a benign affection with an unknown mechanism and an unpredictable occurrence rate; but some etiopathogenic hypotheses have been put forward. Therapeutic attitudes were not assessed in this study. We report two observations of heterotopic ossification on mid-line laparotomy scar which could support the etiopathogenic hypothesis of osteoblastic cells migration in granulation tissue from the neighbouring bone tissue, particularly from the sternum or pubian structures. The etiopathogenic mechanism and treatment of this affection are discussed with regards to previously published literature.

L'ossification hétérotopique (OH) est rare au cours de la chirurgie abdominale et intéresse surtout la pathologie orthopédique. C'est une affection bénigne, de survenue imprévisible, de mécanisme encore discuté et des hypothèses étiopathogéniques sont proposées. L'attitude thérapeutique n'est pas codifiée. Nous rapportons deux observations d'ossification hétérotopique sur cicatrice médiane sus ombilicale qui pourraient supporter l'hypothèse étiopathogénique d'une greffe de cellules ostéoblastiques au sein du tissu de granulation à la faveur d'un tissu osseux de voisinage notamment les structures osseuses xiphoïdiennes ou pubiennes. L'étiopathogénie et le traitement de cette affection sont discutés à la lumière des données de la littérature.

Delayed repair for traumatic abdominal wall hernia: is it safe?

Abdominal wall hernias after trauma have been recognized for more than a century, with the first case reported as occurring after a fall. Traumatic abdominal wall hernias (TAWHs) after blunt trauma are uncommon. The timing of definitive repair, early or delayed, is not clear. We report a case on TAWH and mesenteric avulsion, highlighting the reasons for immediate or delayed repair. A single case study can hardly be considered as a basis for profound changes in the management of post traumatic hernias. However, damage to all layers of the abdominal wall indicates high-energy trauma. In such cases, the damage is not, in all probability, limited to the integumentary system. For the moment, the timing of surgery in any TAWH should be considered differently according to the trauma, the wall defect, clinical and radiological findings, associated injuries, and the clinical status of the patient.

[Anorectal Buschke-Lowenstein tumor. (Three cases report)]. / Tumeur de Buschke- Lowenstein à localisation anorectale. (A propos de trois cas).

Buschke-Lowenstein tumor or giant condyloma acuminata is characterized by a proliferation locally aggressive with extensive tissue destruction. We report three cases of Buschke-Lowenstein tumor with anorectal localization. The histology is characterized by papillomatosis and endo or exophytic acanthosis secondary to papillomavirus. The variety of treatment regimens applied do not allow formulation of definitive therapeutic guidelines.
