Abstract:
Although benign, cutaneous pseudoepitheliomatous hyperplasia (PEH) is oftentimes difficult to distinguish from squamous cell carcinoma (SCC). PEH arises from underlying dermal neoplasia, infection, or inflammation. This case report presents the case of a patient with PEH that occurred as a reactive inflammatory response to a foreign body canine hair, which was originally misdiagnosed as SCC. This case highlights a unique etiology of PEH and the importance of using the patient's social history, physical examination, and appropriate biopsy considerations in complex dermatologic cases where pathology alone is not definitive.

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.
