The cancer associated with "moth eaten" bone that primarily affects adolescent boys is Ewing's sarcoma. This aggressive tumor is a type of bone cancer that typically occurs in the long bones and pelvis and is most prevalent in children and young adults, particularly during the teenage years. The "moth eaten" appearance on radiographs is due to the infiltration of the cancer cells into the bone, causing the bone structure to appear irregular and eroded.

Ewing's sarcoma is characterized by its rapid growth and tendency to metastasize, often presenting in the diaphysis of long bones. Understanding the demographics of the disease is essential, as it predominantly affects younger populations. This is distinct from the other conditions, such as osteosarcoma, which also occurs in adolescents but is typically characterized by different radiographic findings. Multiple myeloma and acute lymphoblastic leukemia, while they can impact the bones, tend to affect different age groups and exhibit differing pathological characteristics. In this context, Ewing's sarcoma stands out due to its specific clinical presentation and age-related incidences.
