title: [Pilomatrixoma of the eyelid. Apropos of a case].
abstract: Primary adnexal tumors of the eyelids are quite uncommon. This diagnosis should be considered in the case of a sub-epidermal tumor. We report the case of a 25-year-old female patient presenting with a left eyelid nodular tumor, which appeared clinically as a whitish swelling of the lateral part of the eyelid, covered by normal epidermis. Ultrasonography showed a heterogeneous structure probably containing calcified areas. Complete surgical removal was performed under local anesthesia. Macroscopically, the tumor was encapsulated, with an irregular surface, and it appeared stony under section. Microscopically, it was characteristic of a pilomatrixoma, with sheets of mummified cells devoid of nuclei, either clear or basophilic, and partially calcified. Neither granulomatous reaction nor ossification were observed. This clinicopathological report recalls that pilomatrixoma may appear as a single nodular tumor of the eyelid.
