Calcified Keratoacanthoma with Tumoral Calcinosis in a 10-year-old Boy: A mere Co-incidence?

Abstract

Keratoacanthoma (KA) is a rapidly evolving benign cutaneous tumor, occurring in elderly individuals with a tendency towards spontaneous regression and histopathologic similarity to squamous cell carcinoma. Tumoral calcinosis is an uncommon condition, associated with the deposition of painless calcific masses. The occurrence of these two conditions in the same patient is a rarity itself, whereas deposition of calcium within the KA lesion in our 13-year-old patient makes it even more intriguing. Such an association has been seldom reported in the literature, and this prompted the current report.
