Abstract: 98 yo woman with exophitic tumor of the forehead
HPI: The patient is a light complected Caucasian with a 4 month history of a keratotic lersion on the forehead. She has a history of nonmelanoma skin cancer. She is a poor historian.
O/E: 4 cm in diameter crusted tumor forehead.
|After crust removed|
The specimen shows cocally confluent ulceration with underlhying granulation tissue and a moderate to dense lymphoplasmacytic infiltrate. This is consistent with erosive pustular dermatosis.
Diagnosis: Erosive Pustular Dermatosis
Discussion: Clinically, I thought this was a nonmelanoma skin cancer. Most cases of EPD are on the scalp but they have been described in other sites.

Abstract; Erosive pustular dermatosis of the scalp is characterized by an idiopathic pustular eruption occurring in association with iatrogenic or incidental, antecedent trauma to actinically damaged skin. We present two cases of erosive pustular dermatosis, one of which occurred on the scalp, the other of which was primarily located on the face. (The editor can send a link to full text if you want.)
