Trichoadenomas are benign hair follicle neoplasms that I occasionally encounter in both my The Woodlands dermatology and Conroe dermatology offices. Clinically, Trichoadenomas are scaly warty like growths that have the appearance of a seborrheic keratosis. They usually arise as single lesions on the face but can be located on any anatomic area. They are differentiated from seborrheic keratoses based on the histologic appearance as Trichoadenomas have characteristic eosinophillic (red) circular structures that resemble hoops. No treatment is necessary but can be removed with shave excision for cosmetic purposes or if they are becoming irritated.
