Radiology pathology conference of Brooke Army Medical Center: trichoblastoma of breast


      The differential diagnosis of a superficial breast lesion detected on mammography typically includes seborrheic keratosis, dermal nevus, epidermal inclusion cyst, and basal cell carcinoma with subcutaneous invasion [Kopans DB. Breast Imaging. 3rd ed. Philadelphia: Lippincott Williams & Wilkins; 2007; pp. 481-2]. The case presented is of a trichoblastoma of the superficial breast.

This case describes and correlates the findings of trichoblastoma of the breast on mammography, sonography, and histology.
