Post-surgical pyoderma gangrenosum (PSPG) represents a specific entity: it shares some clinical aspects of pyoderma gangrenosum (PG), but has a series of its own features. In this paper, two cases of PSPG associated with breast surgery are presented: their analysis, combined with a review of the few other cases reported in the literature, show the particular clinical presentation and evolution of this condition. Firstly, the onset of PSPG follows a sequence. After an apparently normal evolution of scar formation following a surgical procedure, the scar presents with many small dehiscences, which will progressively coalesce to some larger areas of wound ulceration, with no visible granulation tissue. Secondly, the delay between surgery and the beginning of symptoms is variable, from 4 days to sometimes 6 weeks. The process will evolve well beyond what would be expected for the initial wound that was created by surgery, with no self-limitation. The skin ulcerations become larger, despite any local treatment or antibiotics. Thirdly, PSPG can affect any anatomical location with the exception of the nipple-areolar complex. Fourthly, a dramatic response to immunomodulatory drugs will be observed. The pain is an inconstant symptom. Present in the first week after surgery, it can be severe and disproportionate regarding clinical presentation.

We report the case of a 74-year-old man who presented an acute haemoperitoneum further to the rupture of the cystic artery. The bleeding was successfully controlled using embolization. This procedure was complicated by ischaemic necrosis and perforation of the gall-bladder requiring laparoscopic cholecystectomy. Spontaneous rupture of intra-abdominal arteries is a rare event. This usually occurs in abnormal arteries, presenting pseudo-aneurysm or, weakened by arterial hypertension, diabetes or corticotherapy. In the case of a cystic artery rupture, embolization can be safely done as long as the arterial anastomotic network with hepatic parenchyma is sufficient to supply the gall-bladder.

Diaphragmatic rupture after blunt trauma is rare, but indicates a powerful external impact. Associated lesions are often life-threatening and require a rapid diagnosis and management. We report a case of a 24-year-old man, admitted to the emergency department after a serious car accident. He complained of a left sided thoraco-abdominal pain with breathing difficulties. Chest X-ray showed a left diaphragmatic elevation. Computed tomography demonstrated a left haemo-pneumothorax, herniation of the stomach in the chest and a haemoperitonium. Laparoscopically, herniated organs were re-integrated in the abdominal cavity ; the diaphragmatic tear was repaired by both direct suture and synthetic prosthesis. Closure of a small bowel perforation found during the laparoscopic exploration was also performed. We consider this therapeutic modality to be an excellent approach in the management of acute left side diaphragmatic rupture in haemodynamically stable patients. Firstly, it permits an inspection of the thoracic cavity through the diaphragmatic tear and secondly, an easy repair of damaged structures in the abdominal cavity.
