A 62-year-old female presented with a painless, gradually progressive mass in the upper lid of the right eye for 4 years. There was no significant past history or history of any swelling elsewhere in the body. Her uncorrected visual acuity was hand movements in the right eye. On examination a firm nontender mass of size 5 × 5 × 3 cm confined to the right upper eyelid involving the tarsus with necrotic areas present within and excoriation of the lower lid and periorbital skin was noted [Figure 1]a and [Figure 1]b. Excision of the tumor with a margin clearance of 5 mm was done. Histopathological examination revealed cords and nests of undifferentiated cells radiating from follicles with sebocytes and ducts suggestive of sebaceous mantleoma [Figure 1]c and [Figure 1]d. Immunohistochemistry was not done. Lid reconstruction was done using the Cutler Beard technique. On follow-up of 1 year, no recurrence was noted.

| Discussion|| |
A sebaceous mantle is an atrophic form of the sebaceous gland during the resting phase of its cycle which is observed during prepuberty and menopause/andropause. In the resting phase of the cycle, the mantle arises from the infundibulum of the hair follicle and then drops down aside in the form of a mantle or skirt., It is presumed that sebaceous glands involute to form undifferentiated mantles. An adenoma arising from these mantle differentiations is termed as mantle adenoma or mantleoma. Histopathologically, it is composed of cords of basaloid cells that hang downward, just like a skirt, from the junction of the follicular infundibulum and isthmus., On immunohistochemistry they express CD117, CD8, AR, and GATA 3. CD8 which cross-reacts with cytokeratin 15 is more specific to follicle bulges and sebaceous mantles. CK20 positive dendritic cells in addition to CK7 positive cells are admixed in this neoplasm. These neoplasms are completely benign and rarely recur.
