Sports dermatology describes skin conditions occurring in athletes. We describe a man with callosities on his palmar hands and fingers secondary to pull-ups and review sports-related dermatoses involving the hands. A 42-year-old man presented with a several-year history of calluses on his palmar hands. The lesions correspond to areas of contact on his ventral hand with the pull-up bar; therefore, the condition is referred to as pull-up palms (PUP). Sports-related dermatoses affecting the hands include contact dermatitis, infections, lacerations, and mechanical trauma. Several of the sports-associated conditions of the hand are unique to a specific sport. Hand-associated sports dermatoses are reviewed.

Discoid lupus erythematosus is an autoimmune connective-tissue disease that represents a subset of conditions on the cutaneous lupus spectrum. The lesions are characterized by disk-shaped plaques on photo-exposed skin with inflammatory hyperpigmentation and adherent scale. Here, we present a patient with a rare manifestation of discoid lesions on the palms.
