The body louse (Pediculus humanus humanus, sometimes called Pediculus humanus corporis) is a louse that infests humans. The condition of being infested with head lice, body lice, or pubic lice is known as pediculosis. Nits are louse eggs. 2  They are generally easy to see in the seams of an infested person's clothing, particularly around the waistline, under armpits or even in body hair. 3  They are oval and usually yellow to white in color.
Parakeratosis pustulosa (PP) is a cause of distal nail inflammation and nail dystrophy that affects a single digit. It is nonpruritic and minimally painful. This distal digital dactylitis is characterized by the lack of a cuticle along with erythematous swelling of the proximal and lateral nail folds. The distal free edge of the nail demonstrates hyperkeratosis while eczema of the nail bed causes onychomadesis (see Figure 5).
