Three medical doctors have published a case report of a 40-year-old Italian man who developed a tumor in his thigh, near where he “habitually” kept his smartphone in a trouser pocket.

The case was published at the end of August in Radiology Case Reports, a peer-reviewed, open access journal.

The tumor, a painless mass, gradually expanded in the man’s left thigh over a period of six months, they wrote. It grew in his Schwann cells and is known as a schwannoma. It was benign.

Schwann cells play an important role in the functioning of the peripheral nervous system. They make up the myelin sheath, which insulates nerve fibers and helps speed the conduction of electrical impulses. They are present in most organs of the body —whether of mice, rats or humans.

The authors —two Italians and one Moroccan— acknowledge that they “cannot establish a definitive causal relationship” between the tumor and the placement of the phone in the trouser pocket, but they state that the case underscores the “need for further research.”
