Pediculosis capitis is a common condition caused by infestation with the human head louse, \<i\>Pediculus humanus capitis\</i\>, and primarily affects children in the age-group of 6\–12 years. The most prominent symptom is intense scalp itching, yet moving lice or nonmoving nits may be seen on the scalp and hair. Tinea capitis, also known as scalp ringworm, is a superficial fungal infection caused by keratinophilic fungi termed dermatophytes. Tinea capitis is rare in adults, and its symptoms include hair loss, dry scaly areas, redness, and itching. We here report a case of a rare coexistence between pediculosis capitis and tinea capitis in an otherwise healthy adult female, motivating the search for a possible cause of this rare coexistence and alarming dermatologists to be aware of the modified clinical appearance of this coexistence which could be mistaken with other conditions such as cutaneous lupus erythematosus or lichen planopilaris.

Aim: The purpose of the study was to describe the trichoscopic features of pseudonits and to assess the usefulness of trichoscopy in their differential diagnosis.

Methods: A retrospective study was performed on those patients seen for the suspicion of head or pubic lice and who underwent trichoscopy with polarized light at \×10 magnification for a more accurate diagnosis. Forty-two patients (28 males/14 females, mean age: 34.5 years, range: 7\–59) were evaluated.

Results: In 30 cases, trichoscopy confirmed the suspicion of head (24 cases) or pubic (6 cases) lice, whereas in 12 cases it allowed for a final diagnosis of seborrheic dermatitis (5 cases), hair casts (3 cases), trichobacteriosis (2 cases), white piedra (1 case), and trichorrhexis nodosa (1 case), by showing different types of pseudonits.

Conclusion: Hair examination using trichoscopy in routine clinical practice may provide useful information for the correct diagnosis, ranging from common head and pubic lice infestations to rarer shaft abnormalities. Differentiating pseudonits from nits is essential to make the correct diagnosis in order to prevent unnecessary treatment, anxiety, and/or embarrassment

Scalp itch is a frequent complaint in the dermatological set- ting. It is common for the dermatologist to encounter pa- tients with no evident cause of scalp pruritus, making it a distressing situation for both the clinician and the patient. The aim of this paper is to propose a systematic approach to scalp itch, which classifies scalp pruritus into two types: (1) with or (2) without dermatological lesions, and presence or absence of hair loss. Also, it is important to think first about the most common causes and then rule out other, less com- mon etiologies. The acronym SCALLP and the five steps for scalp evaluation (listen, look, touch, magnify, and sample) are useful tools to keep in mind for an assertive approach in these patients.
