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...

INTRODUCTION Skin cancer treatment includes surgical and non-surgical techniques. Among surgical techniques, Mohs micrographic surgery permits a complete evaluation of surgical margins with maximal tissue sparing. MATERIAL AND METHODS Retrospective review of dermatology database of skin cancer cases treated with Mohs surgery at University Hospital Dr. José Eleuterio González from 1988 to 2015...

Skin cancers are the most common malignancies occurring in the Caucasian population. Basal cell carcinoma (BCC) represents 75% and squamous cell carcinoma (SCC) 20% of cutaneous malignancies5,29. The other 5%, including melanomas, are beyond the scope of this article. Over the last decade, a significant rise in incidence of non melanoma skin cancer (NMSC) has been noted16,20,29. However, the mo...

MMS: Mohs micrographic surgery SSDC: sclerosing sweat duct carcinoma INTRODUCTION Sclerosing sweat duct carcinoma (SSDC) is a rare slow-growing malignant tumor of the sweat glands that usually occurs in the head and neck region. SSDC isoftenmisdiagnosedclinically,which can result in tumor mismanagement and recurrence. Recent literature has shifted in favor of Mohs micrographic surgery (MMS) as ...

Dermatofibrosarcoma protuberans (DFSP) is an unusual spindle cell tumor with a high rate of local recurrence with traditional excision. Fortunately, Mohs micrographic surgery yields excellent cure rates for this neoplasm due to contiguous tumor spread and meticulous tumor mapping and margin analysis. We present the unique case of a patient treated with a modified Mohs technique with an analysis...

dHACM: dehydrated human amnion/chorion membrane INTRODUCTION Mohs surgery and repair of lower eyelid surgical defects present unique reconstruction challenges because of risk for ectropion. There are several options to avoid this adverse outcome, but when a patient declines surgical repair, there are no alternatives aside from second-intention healing with or without adjunctive therapy. One pro...

Financial support: None Conflict of interest: None ABSTRACT Basal cell carcinoma is a locally invasive malignant tumor, most frequently affecting Caucasian people. The nasal ala is a frequent site for this neoplasia. The treatment of choice is surgical, and Mohs micrographic surgery is one of the indicated techniques for presenting great accuracy in the histological control of margins and high ...

Optical coherence tomography (OCT) is an imaging technology with the potential to provide high-resolution images of the skin non-invasively. With this device, it is possible to identify a host of skin structures including tumors. In this case report, we demonstrate the use of an OCT device in delineating a lateral tumor margin of an ill-defined basal cell carcinoma prior to Mohs micrographic su...
