Pilomatrixoma of the eyelid is extremely rare in middle age and rarely develops into a large tumor. A 45-year-old female developed a painless, progressive swelling (3.0 cm x 2.0 cm) of the left upper eyelid over a period of two years. Overlying skin was normal in color and texture. A differential diagnosis of dermoid, epidermoid cyst, chalazion and basal cell carcinoma was made. An excisional biopsy was performed. A diagnosis of pilomatrixoma was made on histopathological features (dystrophic calcification of matrix with keratin and foreign body granulomatous reaction, basaloid cells and shadow cells/ghost cells). It also comprises ossification apart from the usual calcification. This is a report of an unusually large ossifying pilomatrixoma in left upper eyelid of a middle-aged woman. The patient should be followed up at regular intervals to rule out any recurrence or malignant transformation.
