Scalp involvement by Sarcoptes scabiei var hominis resembling seborrhoeic dermatitis in two immunocompromised patients with systemic lupus erythematosus.

We report two cases of immunocompromised patients with systemic lupus erythematosus (SLE) who had scalp infestation clinically mimicking seborrhoeic dermatitis.
