Squamous cell carcinoma is a form of skin malignancy that involves squamous cells lining the epidermis. It is the second most common form of non-melanoma skin malignancy. We describe a case of squamous cell carcinoma involving the nail bed of an elderly gentleman that was initially diagnosed as a case of fungal infection of the nail bed.

Infection is a dreaded complication in patients who have underwent arthroplasty and often very challenging to treat. It accounts for lesser than 1% of arthroplasty cases and although low in occurrence, requires appropriate investigations and management to successfully treat the condition. This case demonstrates a case of a rare microorganism with unusual antibiotic susceptibility causing a prosthetic joint infection and the use of serum procalcitonin level as guide in management of the patient.
