In recent years, technology has allowed the development of new diagnostic techniques which allow real-time, in vivo, noninvasive evaluation of morphological changes in tissue. This study compares and correlates the images and findings obtained by high-definition optical coherence tomography (HD-OCT) and reflectance confocal microscopy (RCM) with histology(More)
OBJECTIVE Longitudinal melanonychia (LM) is a common dermatologic problem encountered in everyday practice. Its diagnostic approach is critical as it can be an early sign of nail melanoma. Racial melanonychia is the entity most frequently associated with LM. Because there are no clinical data regarding these associations in a Mexican population, we(More)
OBJECTIVE To describe the results of an intervention program to reduce the rate of surgical site infection (SSI) in the breast tumor department of a referral teaching hospital for patients with cancer. METHODS Preventive measures introduced in the Breast Tumor Department of the study hospital included the following: starting in July 2000, use of sterile(More)
Lobular capillary hemangioma (pyogenic granuloma) has been reported more frequently in the skin (88%) than in the mucous membranes (12%). Granuloma gravidarum is a pyogenic granuloma that develops during pregnancy, often in the oral mucosa. Estrogens apparently increase the inflammatory response of mucous membranes. In this article, we describe the first(More)
UNLABELLED Infundibulocystic basal cell carcinoma is a rare variant. It was first described in 1987 and proposed as a new basal cell carcinoma (BCC) subtype by Ackerman and Walsh in 1990. Dermoscopy is a noninvasive diagnostic technique that allows prompt identification of many types of BCC. However, dermoscopic findings for the infundibulocystic variant(More)
Acral melanoma is the most frequent subtype in the Asian and Mexican mestizo populations. Dermoscopy is a noninvasive diagnostic technique that helps the differential diagnosis of pigmented skin lesions on acral volar skin. We, herein, present a case of acral congenital melanocytic nevus with a parallel ridge dermoscopic pattern. Since the parallel ridge(More)
Transepidermal elimination is a mechanism by which altered dermal extracellular material is discharged through the epidermis. Perforating elastosis is a rare disease characterized by the transepidermal elimination of abnormal elastic fibers. Clinically it manifests as skin-colored keratotic papules that may coalesce and form arcuate or serpiginous plaques.(More)
Most of our current knowledge of melanoma is derived from the study of patients from populations of European descent, for whom public health, sun protection initiatives and screening measures have appreciably decreased disease mortality. Notably, some melanoma subtypes that most commonly develop in other populations are not associated with exposure to(More)
All cases of MM diagnosed in 23 hospitals in Catalonia, from 2000 to 2007 were recorded and melanoma incidence calculated and adjusted for the European standard population via the direct method. The age standardised rate/100,000 inhabitants varied from 6.74 in 2000 to 8.64 in 2007 for all melanomas and from 4.79 to 5.80 for invasive MMs; the Breslow(More)
