BACKGROUND Cryopelling uses diffuse cryotherapy not only on lesions of actinic keratosis but all over the photodamaged skin. OBJECTIVES The aim of this study was to compare two cryopeeling methods (liquid nitrogen- LN and portable system - PS) and demonstrate their efficiency in the treatment of actinic keratoses, patient tolerance, researcher and patient preference and aesthetic results. M...

Basal cell carcinoma and actinic keratosis are frequent neoplasms. Topical treatments include the recently approved imiquimod cream. We describe here the case of a 68-year-old man with multiple actinic keratosis on the forehead, upper trunk and on the left cheek. In addition, an exulcerated basal cell carcinoma was observed. The patient was advised only to treat lesions on the forehead with imi...

Light-response curves (LCs) of chlorophyll fluorescence are widely used in plant physiology. Most commonly, LCs are generated sequentially, exposing the same sample to a sequence of distinct actinic light intensities. These measurements are not independent, as the response to each new light level is affected by the light exposure history experienced during previous steps of the LC, an issue par...

Granuloma annulare is self-limiting cutaneous condition of unknown etiology, causing necrobiotic dermal and subcutaneous papules. A number of conditions have been described in association with Granuloma annulare, including lymphoma, anemia, intestinal bleeding, seronegative arthralgia, vasculitis and autoimmune thyroiditis. This manuscript, as the first report of this combination in Iran, descr...

OBJECTIVE To investigate the influence of a regular oral use of acetylsalicylic acid in the prevalence of actinic keratosis. METHODS A case-control study with dermatologic outpatients above 50 years of age assessed between 2009 and 2011. Cases were defined as those who had been under regular use of oral acetylsalicylic acid for more than six consecutive months. The assessment focused on: age,...

The association of granuloma annulare and some neoplasms is controversial. However, there is an increase in the number of case reports and relevant studies supporting the conceptof granuloma annulare being associated with certain types of hematologic neoplasms and solid tumors.Herein, we describe a 54-year-old woman with a 20-month history of generalized annular lesions that did not respond to ...

Actinic prurigo is a pruritic sun-induced dermatosis classified among the immunologically mediated photodermatoses. The disease is a well-known entity among Native Americans and in Central and South America, however rare in Caucasians with only a few reports from Australia, Britain and France. We report the first case of actinic prurigo in a Scandinavian patient, responding favorably to systemi...

PURPOSE To evaluate the surgical outcomes of ocular surface reconstruction in corneal-conjunctival tumors using fibrin tissue adhesive. METHODS A prospective noncomparative study was performed between May 2013 and February 2015. Patients were submitted to routine surgical procedure for corneal-conjunctival tumor excision followed by amniotic membrane graft transplantation using fibrin tissue ...

Background: Untreated actinic keratosis can advance to squamous cell carcinoma, which in turn is associated with a risk of metastasis. Current treatments for actinic keratosis have many shortcomings. This communication describes the efficacy and safety of a topical cream therapy, Curaderm, containing solasodine glycosides (0.005%) for actinic keratosis. Methods: Randomly assigned patients with ...
