A 31-year-old female had a painless, slow-growing lesion over the right sub-brow region of 3 months duration. Examination showed a localized, subcutaneous, yellowish mass (8 mm × 7 mm) with bluish-black peripheral discoloration [Figure 1]. The mass was firm-to-hard and adherent to overlying skin. The rest of the ophthalmic examination was within the normal limits. A working diagnosis of epithelial inclusion cyst and sarcoid nodule was kept, and an excisional biopsy was performed. The overlying adherent skin was removed with the mass followed by direct closure of undermined normal skin margins. Histopathology showed squamous cells arranged in clusters and nodules containing shadow cells or ghost cells (acellular eosinophilic material) in the dermis layer with unremarkable epidermis [Figure 2]. A foreign-body giant cell reaction was also noted. There were no basaloid cells, and the Congo-red stain did not show any congophilic material. The final diagnosis of eyelid pilomatrixomawas established, and the patient showed she is doing well at 1-year follow-up. | Figure 1: The eyebrow skin lesion showing bluish-black peripheral discoloration

Eyelid pilomatrixoma or pilomatricoma, aka calcifying epithelioma of Malherbe, is a rare benign tumor originating from the hair-root matrix cells. The majority of cases occur in children with a female preponderance. It presents as a solitary, painless lesion that may show rapid progression, especially after trauma.[1] This benign tumor consists of basaloid and shadow cells in combination with inflammation (foreign-body giant cells), calcification, and ossification.[2]
