Giant fibrokeratoma, a rare soft tissue tumor presenting like an accessory digit, a case report and review of literature.

Abstract

INTRODUCTION: Acquired digital fibrokeratoma is an uncommon, benign fibrous tumour that usually occurs in adults as a solitary lesion with a typical size of less than 1cm. CASE PRESENTATION: A 48-year-old Afro-Caribbean man presented to our foot and ankle clinic with a long-standing growth over the plantar aspect of the distal phalanx of the left great toe. The growth was painful and affected the patient's mobility. It had gradually increased in size over a period of 17 years. The growth was completely excised, and the base was allowed to heal by secondary intention. The skin eventually healed, and the patient had a good outcome. The histological results confirmed that the growth was a digital fibrokeratoma. CONCLUSION: This case is of interest because of the rarity of digital fibrokeratoma and the unique morphological appearance of the tumor in this case. Additionally, we emphasise the importance of ruling out other causes of abnormal growths and considering fibrokeratoma during differential diagnoses.
