Symmetric Asymptomatic Plantar Nodules in an Infant

“…[1][2][3] However, the incidence is underestimated. 3 Typically, these lesions are asymptomatic, single, and present since the first months of life.…”

“…Although usually bilateral and symmetrical, they can also be unilateral. [1][2][3] PCFH usually occurs in otherwise healthy children and although mostly sporadic, it can also be hereditary. 2,3 The etiology and natural history of PCFH remain unclear.…”

“…2,3 The etiology and natural history of PCFH remain unclear. [1][2][3] Regression during infancy or persistence into adulthood have been described, [1][2][3] but no malignancy was reported. 2 The main differential diagnoses include plantar fibromatosis and piezogenic papules.…”

“…In general, no biopsy or treatment is required. [1][2][3] Precalcaneal congenital lipofibromatous hamartoma is an underestimated benign condition that can be diagnosed clinically. The clinical awareness and recognition of this disorder can avoid unnecessary complementary exams as well as relieve anxiety of parents.…”
