Baby James McCallum, at just 19 months old, has earned the affectionate nickname ‘little ninja-turtle’ from his parents. His unique and rare skin condition has caused a fascinating growth on his back, which covers an astonishing 75% of his back, leaving both his parents and doctors amazed and puzzled.

When Kaitlyn, 35, gave birth to James on August 19th, 2021, at Morton Plant Hospital in Clearwater, Florida, the ultrasounds offered no indication of the surprise in store for them.
Initially mistaking the growth for a birthmark, Kaitlyn grew increasingly worried as scabbing and lumps appeared on James’s back. As they waited for a diagnosis, the growth continued to expand, covering most of their baby’s back.
After two months and numerous consultations with doctors, baby James was finally diagnosed with giant congenital melanocytic nevus—a benign, tumor-like malformation caused by the abnormal development of pigment cells.

Upon receiving the diagnosis, James’s parents learned that the growth could be eliminated through a series of surgical procedures. Consequently, James underwent two rounds of surgery in February and May 2022.
As a result, most of the nevus was successfully removed, providing James with the ability to comfortably lie on his back. A procedure called tissue expansion followed, where healthy skin from his remaining back was used to replace the nevus.
The surgeries were a success, bringing a great sense of relief to Kaitlyn and Tim. They are now optimistic that one more round of surgery will completely eliminate the nevus, improving James’s quality of life even further. James’s increased mobility and comfort, especially his ability to lie on his back, are evident to his parents and a source of joy for the entire family.
Kaitlyn recalls the early days when the strange growth on James’s back first became apparent. Both she and Tim, along with her mother, Mary, noticed something unusual that resembled a birthmark but seemed different due to scabbing and lumps. Concerned, they consulted with doctors who initially struggled to diagnose the condition. However, once they discovered what it was, the process of removing it began.

Before James’s initial surgery in February 2022, he underwent an MRI to ensure that the mass was not growing internally on his brain or spine. Fortunately, the results came back clear, bringing some relief to his parents.
Kaitlyn and Tim were eager to have the nevus removed as it started to impact James’s sleep. The growth even prevented him from lying flat on his back, making sleeping difficult. The concern of potential melanoma risk also prompted them to seek a plastic surgeon for removal.
Over the course of a few months, two surgeries were performed to remove the bulk of the nevus. Tests on the removed skin came back negative for any diseases, providing further reassurance.
