Peripilar keratin casts, also called pseudonits or hair casts, are thin, elongated, greyish-white, cylindrical, sleeve-like structures that encircle the hair shaft and can easily be slid along the hair. They may be clinically misdiagnosed as nits. ⋯ We report an 11-year-old girl with pseudonits. Although it is not a rare condition, underdiagnosis is common.

Review Case ReportsAgminated spitz nevi: case report and review of the literature.
Spitz nevi are benign melanocytic lesions with many histologic similarities to malignant melanoma. A case of agminated Spitz nevi on a 2-year-old boy's left cheek is reported and 41 other cases of agminated Spitz nevi are reviewed. In this case, two biopsies were performed on two different-appearing lesions and the results of both biopsies showed Spitz nevi.
