Introduction: Breast cancer can spread to the chest wall. It is an aggressive stage of poor prognosis. We have developed a technique of major chest wall resection extended beyond the breast area in order to reduce the recurrence., Patients and Methods: This is a retrospective single-center series of 33 patients with breast cancer spread to the chest wall without metastasis (13 patients present with primary breast cancer and 20 patients present with recurrent breast cancer) treated by major chest wall resection between January 1993 and January 2013, by the same surgeon. Analysis of the results was made by another surgeon., Results: Patients aged between 27-83years with an average of 55years. The removed parts measured 350cm(2) to 1200cm(2), and the average duration of complete healing was 7.9months. The mean follow-up time was 122months (6months-240months). The 1 year survival was 84.4%, at 2years 72.6%, at 3years 69.5% and at 5 years of 66.4%., Conclusion: The technique of major chest wall resection is simple and reproducible. Breast cancer with chest wall extension has a poor prognosis. At the end of the study, 20 of 33 patients who benefit from this technique are still alive., (Copyright © 2013 Elsevier Masson SAS.

The authors report a very rare case of necrobiosis lipoidica, histopathologically confirmed, which happened in the breast a few months following the insertion of a silicone implant (post-mastectomy reconstruction). This case raises two problems: the physiopathology (role of the silicone implant) and the treatment of this accident, resistant to current therapy., (Copyright © 2010 Elsevier Masson SAS.

Aim: The aim of this paper is to discuss, through four cases, the characteristics of sinonasal hemangiopericytoma (SNHP) and its diagnostic difficulties., Materials and Methods: Description of four recent, histologically proven cases of SNHP. Bibliographic research was conducted using the following principal key word: "sinonasal hemangiopericytoma"., Results: The four patients complained of non-specific rhino-sinusal symptoms. In each case, physical examination revealed a voluminous unilateral polyploïd tumour of the nasal cavities, documented by CT Scan and MRI. Each patient underwent complete tumour resection by endoscopic sinus surgery. Histological and immunohistochemical examination confirmed SNHP diagnosis, although no specific marker was constantly observed. To date, none of the patients has presented with recurrence., Conclusion: SNHP is of poorly specific clinical and histological presentation. This tumour is difficult to distinguish from solitary fibrous tumour (SFT), with which it is often confused. SNHP is of good prognosis, however lifelong follow-up must be observed.

The authors report a very rare case of lipome extended to the superficial and deep lobes of parotid gland. MRI remains the best complementary examination to direct the diagnosis; however only the surgery will bring a histological proof formal.
