Textured and smooth breast implants: is there a difference in the chemical structure of silicone?: an analysis with fourier transformation infrared and attenuated total reflectance spectroscopy.

Scientific controversy concerning silicone and its biocompatibility has been ongoing for the last 10 years. This study on textured and smooth silicone breast implant shells using fourier transformation infrared spectroscopy associated with attenuated total reflectance cells aimed to identify eventual chemical modifications of silicone induced by texturization. The surfaces of 8 new implants produced by 2 well-known manufactures have been taken into consideration.

Recurrent atypical eccrine spiradenoma of the forehead.

Eccrine spiradenoma is an uncommon but well recognized benign adnexal tumour of the eccrine sweat glands. It can appear at any age, but the highest rate of incidence is observed among young adults, without any sex predilection. The commonest clinical presentation is a solitary blue-red dermal or subcutaneous cystic nodule, ranging from 0.

Metatypical basal cell carcinoma: a clinical review.

Background: Metatypical cell carcinoma can be considered as a new entity of skin cancer, being an intermediate typology between basal cell carcinomas and squamous cell carcinomas. The behaviour of the metatypical cell carcinoma lies between these two varieties of skin cancer. It is difficult to perform a differential diagnosis based on morphological and clinical features - therefore it is only possible by accurate histology.

Spitz nevus: follow-up study of 8 cases of childhood starburst type and proposal for management.

Spitz nevus is an uncommon, benign melanocytic neoplasm that shares many clinical and histological features with melanoma. It presents clinical ambiguity that makes the diagnosis and management of the patient difficult. We present our experience in the management of Spitz nevus by rigorous dermoscopic long-term follow-up of 8 Spitz nevi in patients younger than 12 years.

Burn after breast reconstruction.

Aims: Burns occur rarely after breast reconstruction, and results from loss of sensory and thermoregulatory skin functions. We aimed to investigate the pathophysiological processes leading to these injuries.

Method: Cases described in the literature are reviewed and discussed.

Poroid hidradenoma: a case report.

Poroid hidradenoma is a variant of the eccrine poroma that belongs to the group of poroid neoplasms. It presents architectural features of hidradenoma, with solid and cystic areas and tumour cells restricted to the dermis, and cytological features of poroid neoplasm such as poroid and cuticular cells. Poroid hidradenoma becomes malignant in less than 1% of cases, but its histologic characteristics may resemble those of malignant neoplasms; thus it is easily misdiagnosed.

An increase in basal cell carcinoma among the young: an epidemiological study in a middle-south Italian population.

During the last 20 years, an increasing incidence of basal cell carcinoma (BCC) has been demonstrated by several studies. A ten-year retrospective analysis on 7,266 cases of primary BCC of the Department of Dermatology and Plastic Surgery of the University of Rome La Sapienza and the Department of Dermatology of the University of Naples "Federico If' is reported. Among a population aged over 35 years, BCC cases increased from 618 in 1994 up to 749 cases in 2003, while among the younger population (<35 years), BCC cases increased from 30 in 1994 to 47 cases in 2003.

Adipose compartments of the upper eyelid: anatomy applied to blepharoplasty.

Many authors have indicated the presence of ectopic or accessory upper eyelid fat pads, but the effective rate of eyelid fat variations and the corresponding clinical features are still unclear. The purpose of this study was to evaluate the variability of upper lid fat and to define the anatomical landmarks of the adipose pockets of the upper lid. From January of 1998 to January of 2002, the authors investigated the upper eyelid fat compartments of 47 patients who underwent upper blepharoplasty.
