BACKGROUND Among nonmelanoma skin cancer (NMSC), basal cell carcinoma (BCC), and squamous cell carcinoma (SCC) are the most common. Giant NMSCs have occasionally reported in the medical literature with particular problems related to diagnosis and treatment. The aim of this study was to analyze patients, treatment, and outcome with giant BCC/SCC. MATERIALS(More)
Adult cutaneous Langerhans cell histiocytosis (LCH) is a rare disease. We report two cases illustrating the variability of the clinical presentation and the response to treatment. In both cases a remission was achieved: in one case a partial remission with psoralen plus UVA irradiation (PUVA) and methotrexate plus topical corticosteroid ointment; in the(More)
The microcirculation of the wound bed is a key parameter for improving granulation tissue formation and, hence, wound healing. The aim of this study was to determine whether a wound dressing comprising collagen/oxidized regenerated cellulose has effects over a short term on wound healing. Wounds were evaluated using a clinical wound score; pain associated(More)
BACKGROUND Myiasis is defined as invasion of tissues by Diptera flies. The condition is endemic in the forested areas of Mexico, Central and South America.
