Thanks for reaching out. Could this be a bite wound from the other hamster? The dark skin is probably necrotic (dead) dermis. It could be an abscess. Infections should be treated with systemic antibiotics and possible anti-inflammatories/analgesia, as it could be painful. A veterinary visit is recommended, as only a veterinarian can prescribe antibiotics. Good luck.
