BACKGROUND Adenosquamous carcinoma (ASC) of skin is a rare but distinctive neoplasm that usually exhibits an aggressive course. To date, 13 well-documented and undisputed cases of primary cutaneous ASC have been reported. This term has been used for tumors with better prognosis, such as mucoepidermoid carcinomas and acantolytic squamous cell carcinomas,(More)
Oral involvement is uncommon in cutaneous T-cell lymphomas and usually associated with poor prognosis. The clinicopathological and immunohistochemical findings of 2 new cases are described along with a literature review. The first patient had a 10-year history of mycosis fungoides when she developed lesions in the oral tissues. She died 6 months later(More)
Knowledge about the molecular mechanisms involved in the pathogenesis of tumoral progression in mycosis fungoides (MF) is still scarce. Because the 9p21 locus seems to be a good target for a detailed study in MF, this prompted us to compare the mechanisms of inactivation of the p16(INK4a), p15(INK4b), and p14(ARF) genes in aggressive and stable forms of MF,(More)
Lichenoid drug eruption is an uncommon, but previously reported, side effect of anti-tumor necrosis factor therapy. The majority of these adverse events relate to infliximab. We report a patient who developed a lichenoid eruption on the back of her hands during etanercept therapy. She improved with topical treatment and discontinuation of the drug was not(More)
