A brownish-yellow, hardened skin growth on a man’s back grew to such massive proportions that it resembled a giant dragon’s horn by the time surgeons finally removed it.
The so-called horn started out humbly as a rough, scaly lesion that first appeared in the middle of a 50-year-old man’s back years ago, according to findings published online in the December 2019 issue of the journal BMJ Case Reports.
Over the next three years, the patch of toughened skin grew progressively bigger. Eventually, it formed a thick, curved, horn-like structure that extended nearly to the man’s waist; at the time of its removal, the growth measured 5.5 inches (140 millimeters) long and over 2 inches (60 mm) wide, reaching just over 2 inches (55 mm) thick.
