Crusted scabies in a patient with brain astrocytoma: report of a case.

A 31-year-old man was referred to our clinic complaining of generalized erythematous and scaly papules and plaques. He suffered from a brain tumor (astrocytoma) and was immunosuppressed because he was receiving systemic steroids and chemo-radiation therapy. He also had psychomotor retardation and behavior changes due to the pressure effect of his brain tumor. The diagnosis of crusted scabies was established based on direct positive skin smears from the lesions.
