Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare cutaneous neoplasm with microscopic similarities to non-cutaneous lymphoepitheliomatous malignancies, particularly undifferentiated carcinoma of the nasopharynx. It can be clinically and histologically confused with other benign and malignant tumors. If not adequately treated, recurrence and distant metastasis are probable. We prese...

BACKGROUND With the advent of incorporating the immunoperoxidase staining technique into the processing of frozen tissue, the use of Mohs micrographic surgery (MMS) has been expanded to include several high-risk tumors such as lentigo maligna, malignant melanoma, and dermatofibrosarcoma protuberans. OBJECTIVES To thoroughly review the English medical literature pertaining to the use of immuno...

Highly sensitive and selective gas sensors with low energy consumption amenable to miniaturization are required for real-time monitoring applications. The challenge is produce sensing units at a sufficiently cost allow broad deployment, which can only be reached efficient materials fabrication procedures. In this context, metal oxides promising next-generation due their high surface-area-to-vol...

OBJECTIVE Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal. METHODS The records of patients who underwent Mohs micrographic surg...

An 80-year-old woman presented for surgical treatment of an invasive squamous cell carcinoma on the left temple (Figure 1). The lesion had been present for several months and had been enlarging. The patient did not have any motor deficit in the forehead region. The tumor was removed in two stages using the Mohs technique (Figure 2). Nerve tissue was not seen on the Mohs slides. The defect was c...

The presence of perineural invasion in skin tumors constitutes a major risk factor for local recurrence.1-3 Perineural invasion is not a common finding in basal cell carcinomas, with an estimated incidence that, depending on the series, varies between 0.17%2 and 3.8%.4 The frequency is higher in more aggressive histological subtypes and in recurrent tumors.1,2,4,5 The patient was a 69-year-old ...
