Can you guess the diagnosis? A 28-year-old patient presents with numerous small, firm, skin-colored to light-brown papules that have gradually increased over several years. The lesions form symmetrical clusters on the upper and lower eyelids, with additional scattered papules on the lateral face and neck. The papules are uniform and asymptomatic, without inflammation, comedones, or surface scaling. A punch biopsy reveals small eccrine ductal structures within a dense fibrous stroma. Classic diagnostic clue: Symmetrical clusters of tiny periocular papules with similar lesions on the neck.
