Trichofolliculomas are benign hair follicle hamartomas which were initially considered as hair follicle tumors. Usually presenting as a solitary lesion associated with a tuft of vellus hairs, multiple trichofolliculomas are rare. Trichofolliculomas are characterized by a histopathological feature of dermal keratin cyst with cyst wall showing radiating hair follicles. We report this case for the rare presentation of multiple trichofolliculomas on the face which clinically mimicked multiple trichoepitheliomas.
毛发毛囊瘤是一种良性毛囊错构瘤,最初被认为是毛囊肿瘤。通常表现为单个病变并伴有一簇毳毛,多发性毛发毛囊瘤较为罕见。毛发毛囊瘤的组织病理学特征为真皮角质囊肿,囊肿壁可见呈放射状排列的毛囊。我们报告该病例,其为面部多发性毛发毛囊瘤的罕见表现,临床上酷似多发性毛发上皮瘤。
