Longitudinal melanonychia has a broad differential diagnosis including melanoma. Subungual haematomas rarely present as dark bands resembling longitudinal melanonychia. A 35-year-old Caucasian tennis player presented with a decade-long history of black bands involving bilateral great toenails [Figure 1]. Dermoscopy showed homogeneous areas and globules without melanin lines [Figure 2]. Nail plate clippings with histopathology showed entrapped blood without hyphae or melanin. Stopping short while playing tennis may force the toes into the narrow part of the sneaker, rupturing subungual blood vessels. Tennis toe is most common in the great toenail in patients ≥35 years old. The patient’s avid tennis history likely resulted in subungual haematomas from trauma.
