Microbiological evaluation of tissue expanders in patients who had first stage breast reconstruction.

Capsular contracture is one of the most common complications associated to the use of foreign materials in reconstruction after mastectomy and aesthetic breast augmentation. Many risk factors, causes, and conditions seldom associated with capsular contracture have been identified but none of these have been confirmed by published data. Among these, subclinical infections (particularly those caused by Staphylococcus epidermidis) seem to be one of the most likely. In the present study we analysed the correlation between capsular contracture and the incidence of periprosthetic subclinical infection in two groups of patients who had first-stage breast reconstruction: one group of patients who were not having adjuvant or neoadjuvant radiotherapy for breast cancer (n = 25) and a second group of patients who had had quadrantectomy and radiotherapy (QUART) and successive radical mastectomy for recurrent disease (n = 25). Patients who had radiotherapy had a significantly higher incidence of subclinical infection (n = 13) than patients who did not (n = 1), but there was no statistical correlation between subclinical infection and capsular contracture. Subclinical infections seemed to present at a later stage and under certain local and systemic circumstances that favoured bacterial growth, such as radiotherapy.

Three cases of embolia cutis medicamentosa (Nicolau's syndrome).

Embolia cutis medicamentosa, also known as Nicolau's syndrome, is a rare complication due to i.m. injections. Its real incidence is actually underestimated. Many drugs have been associated with it, but at the time only a few studies showed a related pathogenetic mechanism. Symptoms consist of immediate local pain, edema and cutaneous, subcutaneous and even muscular necrosis occurring in the first 48 h. The type of treatment depends mostly on time of diagnosis. A medical resolution can be achieved through heparin and cortisone injections within the first 48 h. Surgical debridement has to be considered as the main treatment in case of late diagnosis. We present three cases of Nicolau's syndrome presenting to us in a short period of time that we treated with surgical debridement.

Multiple localization of granular cell tumour: a case report.

INTRODUCTION: Granular cell tumour, also known as Abrikossoff's tumour, is a rare entity occurring in the skin as well as in internal organs, more common among the third to fifth decade of life. It has often been described as a peripheral neuroectodermal tumour and its clinical behaviour is usually benign although malignant and multifocal forms are also known to occur. CASE PRESENTATION: We report a case of multiple granular cell tumour in a 17-year-old Caucasian woman who presented with a nodular lesion in the popliteal cave, diagnosed as an Abrikossoff's Tumour, followed 2 years later by another soft tissue mass in the neck. CONCLUSION: This case is quite rare: only a few cases were presented in literature with an extended period of time before the clinical presentation of subsequent disease.
