A Rare Case of Coinfection with White Piedra and Pediculosis Capitis

On scalp hair examination, there were multiple white‐to‐brownish, firm‐to‐hard, 2–3 mm sized nodules distributed at irregular interval and encircling the hair shaft completely [Figure 1]. The nodules could not be slid over the hair shaft. Moreover, structures resembling nits were seen in the retroauricular area. Hair pull test and tug test were negative. Scalp was otherwise normal with no signs of inflammation. The other hair bearing sites of the body were normal. Rest of the cutaneous and systemic examination including lymph node examination was normal. The differential diagnosis of pediculosis, piedra, keratin pilar cast, and trichoblastosis were kept.
