Histopathology of the nail.
Introductory sections on why and how to biopsy the nail unit and on the handling and processing of the specimen are followed by a presentation of normal histologic findings. These are contrasted with the abnormal changes in infections, especially fungal, of the nail unit, and in skin diseases that may affect the nail, especially psoriasis and lichen planus. Benign and malignant neoplasms that may occur beneath or around the nail, including melanoma, conclude the discussion.
