Aim and background: Pilar cysts in the foot are uncommon occurrences and pose diagnostic challenges, as they are difficult to distinguish from other cystic lesions through both clinical examination and radiological imaging. Consequently, surgical excision is often deemed necessary for definitive diagnosis and treatment. Case description: A 12-year-old female presented with persistent right foot pain subsequent to a glass prick injury. Ultrasonography (USG) of the foot suggested an infective collection, while magnetic resonance imaging (MRI) revealed a well-lobulated lesion along the plantar aspect of the 3rd and 4th toes, initially indicative of a posttraumatic collection or hemangiovenous malformation. Excision biopsy was performed, and histopathological examination revealed a classical pilar cyst with the cyst wall lined by keratinizing squamous epithelium. Conclusion: Pilar cysts in the foot are exceptionally rare and can mimic foreign body granulomas or arteriovenous (AV) malformations. Surgical excision emerges as the preferred treatment for symptomatic cases, emphasizing the significance of accurate diagnosis and intervention. Clinical significance: Persistent foot pain subsequent to a glass prick injury warrants thorough investigation, including consideration of foreign body granuloma or pilar cyst. This case underscores the need for surgical intervention in such cases to rule out uncommon but significant pathologies and provide appropriate treatment.
