Differential Diagnosis
(In a Page: Signs and Symptoms)
- Onychomycosis
–Very common cause of nail thickening,
yellowing, and subungual debris
–Due to a dermatophyte infection
–May affect one or all fingers and toenails
–Patients often have coexisting tinea pedis or
tinea manum
- Psoriasis
–More than 50% of patients with psoriasis have associated nail changes, including pits, “oil spots,” and onycholysis
–Distinguishing nail fungus from psoriasis can be very difficult on clinical exam
–Most patients with nail disease have some other skin manifestation of psoriasis (plaques of thick, silvery white, adherent scalp scale that overlies well-demarcated patches of erythema)
- Paronychia
–Tenderness, erythema, and peeling around
the nail
–Very common and exquisitely painful
–Often exacerbated by “wet-work” (e.g.,
dishwasher)
–May have bacterial and/or yeast (candida)
component
–Occurs after minor cuticular trauma
–Can cause nail dystrophy without treatment
- Nail trauma
–Very common, especially great toenails and
thumbnails
–Easily misdiagnosed as fungal disease
–Can cause separation of the nail from the
nail plate
-
Malignancy (e.g., subungual melanoma, squamous cell carcinoma)
-
Endocrine disease (e.g., hyper- and hypothyroidism) can cause splitting, drying, and other nail changes
-
Lichen planus and atopic eczema can affect the nail matrix and lead to nail dystrophy
-
Alopecia areata (patchy autoimmune hair loss) can be associated with nail pits as well

Several congenital disorders (e.g., ectodermal dysplasia) can cause nail dystrophy in association with other skin and systemic disorders
