Abstract
Tumor of the follicular infundibulum (TFI) is a rare benign cutaneous adnexal neoplasm first described by Mehregan and Butler in 1961.1 TFI most commonly presents as a solitary papule, plaque, or macule, on the head and neck region.2 Clinical variants include multiple or eruptive forms.3 Histopathologically, solitary lesions present as platelike subepidermal proliferations of eosinophilic, pale-staining keratinocytes, creating a reticulated pattern.3, 4 Many cases of TFI have been associated with other cutaneous lesions, stimulating discussions surrounding the histogeneis of TFI. Basal cell carcinoma (BCC) is the most commonly reported association, with varying rates of associated lesions seen in other reports.3 Here, we present the case of a 69-year-old man with TFI and an associated dysplastic nevus.
