Description

Optimizing diagnostic yield from nail unit specimens starts with matching the suspected disease to the most appropriate sampling approach and then preserving anatomy, orientation, and clinical context from procedure to slide. Practical submission strategies include separating nail plate from accompanying soft tissue, using templates or paper supports to prevent curling of thin specimens, and supplying complete clinical details (including photos and expected orientation) to guide grossing and sectioning. The strengths and limitations of common procedures are reviewed: clippings/avulsions for onychomycosis, inflammatory disorders, select neoplasms, and screening pigmented nail plate changes; matrix shave/targeted biopsies for visible matrix lesions; punch biopsies for a broad range of conditions but with higher risk of “blind” sampling in melanonychia; and longitudinal en bloc excision as the gold standard for preserving nail unit architecture and reducing embedding/sectioning errors, particularly valuable in complex entities such as onychopapilloma. Processing pitfalls—brittle nail plate, section fracturing, tissue wash-off, crush artifact, and loss of key epithelium—are addressed with best practices such as nail softening protocols, perpendicular embedding, pre-soaking blocks, longer baking, and conservative use of levels and PAS to preserve tissue for immunostains and ancillary studies. Targeted stains can clarify common diagnostic dilemmas: Fontana-Masson for subtle melanin (with attention to titration and air-bubble mimics) and modified benzidine-based methods for hemoglobin in nail hemorrhage, emphasizing why hemosiderin stains are typically unhelpful. Overall, accurate nail pathology is framed as a team effort requiring close clinician–dermatopathologist collaboration and deliberate handling at every step to maximize interpretability and diagnostic confidence.
