Background: Cutaneous myiasis in patients with malignant wounds or skin cancer is a rare and undesirable event with limited epidemiological data. A subregister of reports, lack of education in the population, inadequate empirical treatments, and medical underestimation are components of a public health problem that threatens patients' lives.
Methods: We conducted a systematic review of the literature of cutaneous myiasis associated with malignant wounds and skin cancer, characterizing sociodemographic variables, risk factors, clinical and histological features, and treatment.
Introduction: Gastric pseudotumors are rare entities whose clinical presentation resembles typical gastric neoplasias, often making them unrecognized unless other causes are considered.
Presentation Of Case: We present a case report of a patient that debuts with dysphagia, with an abdominal computed axial tomography (CAT) scan revealing a mass at the gastro-esophageal junction suggestive of malignant origin, with studies revealing it to be Immunoglobulin G4-related (IgG4).
Discussion: The diagnosis and identification of IgG4-related gastric pseudotumors is very complicated, often and most commonly an incidental diagnosis upon histologic analysis, as is the situation in this case.
Introduction: Angiokeratoma corporis diffusum are benign capillary malformations typically associated with Fabry disease and other lysosomal storage disorders. Only in a few cases they appear in healthy individuals.
Methods And Case: We carried out an exhaustive review of the literature on angiokeratomas and their main clinical, dermoscopy and histological features.
Cell culture on biopolymeric scaffolds has provided treatments for tissue engineering. Biopolymeric mixtures based on gelatin (Ge), chitosan (Ch) and hyaluronic acid (Ha) have been used to make scaffolds for wound healing. Thermal and physical properties of scaffolds prepared with Ge, Ch and Ha were characterized.
