Using computational learning for non-melanoma skin cancer and actinic keratosis near-infrared hyperspectral signature classification.

Background: The early detection of Non-Melanoma Skin Cancer (NMSC) is essential to ensure patients receive the most effective treatment. Diagnostic screening tools for NMSC are crucial due to high confusion rates with other types of skin lesions, such as Actinic Keratosis. Nevertheless, current means of diagnosing and screening patients rely on either visual criteria, that are often conditioned by subjectivity and experience, or highly invasive, slow, and costly methods, such as histological diagnoses.

[Localized acquired cutis laxa associated with trachyonychia].

Acquired cutis laxa is a rare disease of unknown cause, which affects elastin metabolism. Clinically, it is characterized by redundant skin and hyperelasticity, while the histological study shows a reduction in or absence of elastic fibers in the dermis. We present a case of localized acquired cutis laxa associated with trachyonychia.

[Herpetiform pemphigus associated with esophageal carcinoma].

We present the case of a 63-year-old woman with herpetiform pemphigus and disseminated esophageal carcinoma which began to manifest themselves simultaneously. Some cases of herpetiform pemphigus associated with neoplasms have previously been reported, but these have primarily been bronchopulmonary. The association of any type of pemphigus with esophageal cancer is very infrequent.
