Primary Bone Lymphoma: A Rare Case of Anaplastic Large Cell Lymphoma in Calcaneus in a Child.

INTRODUCTION

Primary bone lymphomas are rare, and primary anaplastic large cell lymphomas (ALCLs) of bone in a child are even rarer. A case of primary ALCL of calcaneus in a 7-year-old child is presented.

CASE REPORT

Child aged 7 years presented with fungating swelling over his right heel which was associated with fever. The diagnosis was established by immunohistochemistry (CD30, ALK) of the biopsied specimen. Treatment was done by chemotherapy and subsequent radiotherapy. At 12-month follow-up, the child was ambulant with complete resolution of the swelling.

CONCLUSION

Masses arising from the foot and ankle can be a diagnostic challenge, and both infection and neoplasm should be considered in its differentials.
