A rare case of invasive keratinizing squamous cell carcinoma of the foot

Abstract

Lower extremity soft-tissue lesions are frequently encountered in clinical practice. Cellulitis, osteomyelitis, and diabetic foot ulcerations remain the top differentials. The acuity of illness, imaging studies, and deep wound cultures are helpful in most cases. Malignancies are rare but need immediate attention. Hereby, we report a case of a chronic heel wound which on workup was confirmed as cutaneous squamous cell carcinoma (SCC).
