Periungual fibroma in Adult
Nontraumatic periungual fibromas are a major diagnostic criterion for the diagnosis of TSC. However, patients with a preceding history of trauma should also be examined for manifestations of TSC. "Red comets" (erythronychia) and longitudinal grooves may be found in nails of patients with TSC, and these findings should increase clinical suspicion of TSC, even in the absence of periungual fibromas.
