Abstract:
Keratoacanthomas rarely occur in the conjunctiva. We report a case of a 24-year-old man with a rapidly growing conjunctival mass. The tumor was excised with a safety margin to exclude squamous cell carcinoma and was histopathologically diagnosed as a keratoacanthoma. There has been no recurrence over 2 years of follow-up. To the best of our knowledge, he is the youngest patient to be diagnosed with conjunctival keratoacanthoma who had no known risk factors such as skin disorders, trauma, surgery, or infection. In similar cases, we recommend complete early surgical excision and careful follow-up to exclude malignancy.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
