ABSTRACT

Pilomatrixoma is a rare, benign, calcified, adnexial soft tissue tumor of the eyelid which originates from the matrix of hair follicle. In this study, we aimed to present a pilomatrixoma case which presented as a benign mass at the lower part of the eyebrow. An 8-year-old child patient referred to our clinic with a painless mass at the right superior eyelid which had appeared 1,5 month before and seemed to be increasing in size for the last week. The ophthalmologic examination revealed a lobular, 0,7x1 cm sized, pink–violet, solid, swollen mass at the lower part of the right eyebrow. The position of globe was normal and the ocular motility was unrestricted. Orbital computed tomography (CT) revealed 7 mm sized, smooth, noninvasive, benign, homogeneous, well-contoured mass lesion. The lesion was totally excised with sharp dissection under general anesthesia. Benign pilomatrixoma (Malherbe tumor), which is frequently seen especially in the initial two decades, is to be kept in mind in the differential diagnosis of eyelid masses. We should follow up the patients for long term due to possible malignant transformation of pilomatrixoma.
