Giant porokeratosis (PK) is a rare entity. Many consider it as a variant of PK of Mibelli, while others describe it as a separate variant. The diameter may range between 10 and 12 cm and the wall of hyperkeratotic ridge may be upto 1 cm. High tropical temperature and long duration of outdoor activities without adequate clothing are known influencing factors of PK. To the best of our knowledge, only five cases of solitary giant PK and a case of disseminated giant PK have been documented from India. We report three cases of giant PK for their rarity.
