Bottom Line: In most cases the diagnosis is made with the help of histopathology, due to lack of a characteristic clinical presentation.The most common form is a solitary lesion, but it can be multiple or eruptive, then called infundibulomatose.This case report illustrates a patient with multiple lesions of tumor of the follicular infundibulum with bizarre aspect and atypical location.

ABSTRACT
Tumor of the follicular infundibulum is a rare benign cutaneous adnexal neoplasm with variable clinical presentation. In most cases the diagnosis is made with the help of histopathology, due to lack of a characteristic clinical presentation. The most common form is a solitary lesion, but it can be multiple or eruptive, then called infundibulomatose. This case report illustrates a patient with multiple lesions of tumor of the follicular infundibulum with bizarre aspect and atypical location.

f05: Cytoplasm of cells strongly stained by PAS due to accumulation of glycogen (100xmagnification)

Mentions: Two biopsies were done in distinct sites. The microscopic examination evidenced benignepithelial neoplasm, characterized by irregular projections that are formed in theepidermis and are anastomosed with each other in the subjacent dermis, whose cells showclear cytoplasm with normochromatic regular nuclei (Figure 3 and 4). PAS staining wasstrongly positive in the cytoplasm of these cells (Figure5). The stroma of neoplasm is fibrillar connective with proliferation of bloodcapillaries. These findings were consistent with the diagnosis of multiple tumor offollicular infundibulum (infundibulomatosis).
