Atypical Giant Cutaneous Horn with Previous Insult: Two Cases with Review

Cutaneous horns, or cornu cutaneum, are uncommon, keratinized protrusions typically found on sun-exposed skin areas. This article reports two cases of giant cutaneous horns located in covered body areas deltoid and thigh regions from a tertiary healthcare center in northern India. The first case is a 28-year-old female with a progressively enlarging horn on her right arm following a burn injury, and the second case is a 50-year-old male with a horn on his thigh following recurrent abscesses. Despite the usual benign nature of cutaneous horns, their potential for malignancy necessitates thorough histopathological examination. These cases highlight the rare occurrence of giant cutaneous horns in non-sun-exposed areas, emphasizing the need for further research into their etiopathogenesis.
