he correct answer is C. Genetic counseling.

The presentation of palmar pits in a child with a history of medulloblastoma and a prior basal cell carcinoma is most concerning for basal cell nevus syndrome (i.e., Gorlin syndrome). Genetic counseling, along with a variety of imaging tests, should be performed to monitor the patient.

Abdominal or pelvic imaging is necessary for children that are closer to the age of puberty so as to evaluate for ovarian fibromas. Bone density scanning and a HIDA scan are not necessary for this patient.
