Genital Nodular Scabies: A Case Report

Abstract

Scabies is a highly infectious skin disease caused by the ectoparasite; Sarcoptes scabiei var. hominis. It is an often neglected skin disease which is especially common in developing countries particularly, in poor hygienic conditions. It typically presents as erythematous, papular, vesicular or nodular rashes with crusts or excoriations. Nodular scabies is an uncommon variant seen in about 7% of patients with scabies. The most common sites of nodular lesions are the genitals and scrotum. This case report explored a case of genital nodular scabies involving the phallus and scrotum of a man who complained of a rash on the phallus and scrotum. There was associated genital itching which was worse at night. Examination revealed erythematous, firm, nodular rash on the glans penis, penile shaft and scrotum. A diagnosis of genital nodular scabies was made. The risk factors identified were poor hygienic practices. Treatment included oral ivermectin and antihistamines with total resolution of symptoms.
