OBJECTIVE To determine long-term tumor recurrence rates after treatment of primary nonmelanoma skin cancer (NMSC). Data are currently insufficient to permit evidence-based choices among treatments for NMSC. DESIGN Prospective study of an inception cohort observed for a median of 6.6 years after treatment. SETTING Dermatology clinic at a Veterans Affairs hospital. Care was provided by dermat...

AE1/AE3: anti-pan cytokeratin 1/3 ART: adjuvant radiation therapy H&E: hematoxylin and eosin IHC: immunohistochemistry SCC: squamous cell carcinoma INTRODUCTION Mohs micrographic surgery remains the gold standard for the treatment of cutaneous squamous cell carcinomas (SCCs) of the head and neck. However, for recurrent or aggressive SCCs, it can be challenging at times to ensure complete margin...

Mohs' micrographic surgery of facial basal cell carcinoma ensures a high cure rate with maximal preservation of healthy tissue. Using precise margin control, this procedure allows complete examination of all margins of tissue removed. Due to the insufficient facilities for Mohs' micrographic surgery in Sweden, only the most aggressive tumours are referred for this procedure, which could increas...

Mohs micrographic surgery allows for complete microscopic examination of the surgical margin when treating aggressive and recurrent facial basal cell carcinomas. This leads to the highest cure rates and maximal preservation of healthy tissue. The 5-year recurrence rates of 587 aggressive and/or recurrent facial basal cell carcinomas treated during 1993 to 2003 at our centre were studied retrosp...

BACKGROUND Microcystic adnexal carcinoma, or sclerosing sweat duct carcinoma, is an uncommon cutaneous neoplasm associated with extensive local invasion. The standard of care with regard to the best excisional method in treating microcystic adnexal carcinoma has not been established. OBJECTIVES To perform a retrospective study comparing patients treated by Mohs micrographic surgery with those...

BACKGROUND Malignant proliferating trichilemmal tumor (MPTT) is a rare neoplasm originating in the outer sheath of a hair follicle that often presents as a slowly enlarging, painful, subcutaneous scalp nodule. The authors describe a case of malignant proliferating trichilemmal tumor (MPTT) in an elderly 65-year-old Asian male who presented with a 5.5 x 5.0 cm mass on the posterior scalp. METH...

Technology has been successfully applied in sports, where biomechanical analysis is one of the most important areas used to raise the performance of athletes. In this context, this paper focuses on swim velocity profile identification using Radial Basis Functions Neural Networks (RBF-NN) trained by the Gustafson-Kessel clustering combined with a novel Dynamic Self-adaptive Multiobjective Harmon...
