Background: Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the development of benign hamartomas in multiple organs. Most patients with TSC exhibit cutaneous manifestations. Methods: We report a 28-year-old patient with multiple pink papules at the proximal nail fold of several toes. Results: Histopathological analysis of a biopsy of a papule was consistent with an ungual fibroma. Histopathological analysis of a biopsy of an elevated skin-colored plaque at the lower back was diagnostic for a Shagreen patch. These findings were consistent with a clinical diagnosis of TSC. This patient was subsequently referred to a multidisciplinary TSC clinic for further screening, which revealed a giant cell astrocytoma and multiple subependymal tubers. Annual monitoring was recommended. The skin lesions were treated with topical rapamycin ointment. Conclusions: Recognizing dermatological manifestations of TSC is of importance to allow early diagnosis. TSC should be considered as a differential diagnosis in the case of ungual fibromas, even in older patients.
