Pseudoepitheliomatous hyperplasia arising from hypertrophic lichen planus mimicking squamous cell carcinoma: limited value of immunohistochemistry.
نویسندگان
چکیده
Hypertrophic lichen planus shows prominent hyperplasia and overlying orthokeratosis of the epidermis. To date, 50 cases of squamous cell carcinoma (SCC) have been reported as neoplastic transformation of hypertrophic lichen planus. We report a case of pseudoepitheliomatous hyperplasia (PEH) simultaneously found in hypertrophic lichen planus lesions simulating SCC, with special reference to the value of immunohistochemistry in differential diagnosis.

BACKGROUND Retinoids have the capacity to accelerate the involution of multiple keratoacanthomas, including unusual variants such as keratoacanthoma marginatum centrifugum and keratoacanthoma en plaque that may persist and be associated with progressive growth and provide difficulties in diagnosis and management. OBSERVATIONS We describe 3 patients who had unusual infiltrated and keratotic pl...
