Decubitus ulcer is a pressure sore that could be anywhere on the body, and in this case is on the head because the baby can't move.
Ecthyma gangrenosum is an infection usually seen in patients who are critically ill and immunocompromised. The characteristic lesions of ecthyma gangrenosum are haemorrhagic (bloody) pustules that evolve into necrotic (black) ulcers, which doesn't really fit the description here.
Kerion is an abscess caused by a fungal infection, and likely wouldn't be ulcerative
Recluse spider bite would have more severe systemic symptoms in a child (weakness, fever, joint pain, hemolytic anemia, thrombocytopenia, organ failure, disseminated intravascular coagulation, seizures, or death) and you would see puncture wounds.
I didn't think atypical TB or scabies made sense so I didn't go into those.
