Abstract. The paper proposes new exposure data on etiopathogenesis basal cell epithelioma and present a clinical case investigated dermatoscopic, biochemically, treated surgically and guided to avoid relapses. The case presented is part of typical cases of pigmented basal cell carcinoma. Biochemical and haematological investigations performed one day before the excisional intervention (results 1) and 30 days (results 2) after the intervention: It is recommended to monitor biochemical investigations in which alterations were found, and ways for raising the immunological status.
Christmas tree cataract is a rare type of lens opacification which is usually age related, though several cases have been seen in patients with myotonic dystrophy. It consists of highly refractive multicolored needle-shaped opacities within the deep cortex of the lens (1). The exact mechanism of crystals is not exactly known, but different theories have been proposed. Shun-Shin et al. postulated that the crystals were most likely of cystine due to an age-related aberrant breakdown of lens induced by elevated Ca++ levels (1). According to Anders and Wollensak, the crystals were cholesterol in nature and were the result of lens metabolism (2). A 64 years old female presented with reduced visual acuity in her right eye. Her best corrected visual acuity (BCVA) in right eye was 6/10 Snellen chart. Slit lamp examination after pupillary dilatation revealed highly reflective, polychromatic, needle-shaped crystals in the temporal and inferior cortex of the right lens with associated nuclear sclerosis. This aspect of glittering multi-colored opacities varying with the angle of light incidence resembles the colored lights decorating the Christmas tree(Fig.1). As the visual acuity was significantly reduced and there were no other associated ocular pathologies, we decided for a cataract surgery in the right eye. Since the crystals are highly refringent and change considerably the viewing of the surgeon during the procedure, an increased time of surgery should be avoided (3) (4). Uneventful extracapsular phacoemusification of the lens with monofocal artificial intraocular lens implantation within the capsular bag was performed with very good results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
