Suprapubic Panniculitis with Localized Hypertrichosis in an Infant

Panniculitis is a heterogeneous group of inflammatory conditions initiated by multiple factors, yet rarely reported in children. We describe a 5-month-old healthy Asian male infant with a small asymptomatic indurated swelling just above the pubic crest. His general physical and systemic examination was reassuring. Clinical and laboratory parameters for systemic inflammation were unremarkable. Close follow-up showed longitudinal growth along with localized abnormal hair growth. Histopathological examination confirmed the diagnosis of panniculitis. The induration continued to be persistent, yet stable and asymptomatic till 24 months of age. Keeping in mind the self-limiting nature of localized panniculitis in children, the infant was managed conservatively with a close surveillance. These rare findings of panniculitis in children can pose a diagnostic challenge. Physicians should be aware of this benign and localized form of panniculitis in children to avoid unnecessary investigations and interventions, as there is no specific treatment.
