Adamantinoma Presenting With Local Recurrence and Inguinal Lymph Node Metastasis: A Case Report

Adamantinoma of long bones is a slow-growing, low-grade primary malignant bone tumor. It is a rare entity and accounts for less than 1% of all primary bone tumors, and in most cases, it occurs in the mid-axis of the tibia of adolescents and young adults. In this report, we describe the case of a 53-...

Summary:Adamantinoma of long bones is a slow-growing, low-grade primary malignant bone tumor. It is a rare entity and accounts for less than 1% of all primary bone tumors, and in most cases, it occurs in the mid-axis of the tibia of adolescents and young adults. In this report, we describe the case of a 53-year-old woman with a diagnosis of adamantinoma of the left tibia who was initially treated surgically in 2004. Two years later, she presented with local relapse, for which she underwent new surgical management. The patient was referred to our practice 16 years after the initial diagnosis, and she presented with recurrence characterized by ipsilateral inguinal lymph node metastasis. The histological findings and immunohistochemistry were compatible with metastatic adamantinoma with high-grade differentiation, which ultimately required surgical salvage management.
