A 75 year old man presented with a four month history of presumed paronychia of his right index finger. Antibiotic and antifungal treatment had not been effective. Destruction of the distal phalanx on plain radiographs was thought to be caused by osteomyelitis⇓.
Surgical debridement showed a well defined subungual mass. Histological examination confirmed invasive, moderately differentiated squamous cell carcinoma of the nail bed with no infection.
Although the causes of squamous cell carcinoma are uncertain, it is the most common primary nail bed malignancy. Metastasis is rare and no regional lymphadenopathy was found. Amputation through the middle phalanx resulted in clear tumour margins.
Subungual squamous cell carcinoma can mimic benign conditions and should be suspected in atypical presentations
A multidisciplinary approach to the assessment, management, and follow-up of these lesions is advised
If in doubt, any bone or soft tissue tumour should be discussed with the appropriate tertiary referral service
