Cytomegalovirus (CMV) encephalitis in immunologically normal patients is rarely reported in the literature. CMV infection was diagnosed by viral DNA probe techniques on CSF cells in a 32-year-old, immunologically normal male presenting with a severe clinical picture due to encephalitis. Administration of ganciclovir was followed by an immediate improvement in the patient's condition. More sensitive techniques for CMV detection could allow to discover more cases of CMV encephalitis in non-immunocompromised patients than previously recognized.
reported a case in an immunosuppressed patient and suggested the role of decreased immune surveillance in the production of this lesion. Differential diagnoses to consider include acantholytic dermatoses such as pemphigus, Grover's disease, and Hailey-Hailey disease. These disorders are more extensive papular, vesicular, or papulovesicular eruptions. Acantholytic acanthoma can be differentiated from various acanthomas by the outstanding acantholysis. In focal acantholytic dyskeratosis and warty dyskeratoma, Darier-like alterations are more prominent; in epidermolytic acanthoma, epidermolytic hyperkeratosis are more prominent; in lichenoid keratosis, lichenoid hyperplasia; and in pale cell acanthoma, clear cell acanthosis. 1 Acantholytic acanthoma lacks the cellular dysplasia of acantholytic solar keratosis and the general configuration of an acantholytic seborrheic keratosis. 2 As acantholytic acanthoma is a benign solitary condition, simple excision is the treatment of choice.
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.
