Abstract:
Subepidermal calcified nodule, a rare variant of calcinosis cutis, is a benign lesion typically affecting the eyelid in children. We report a 14-year-old boy presenting with bilateral nodules on the upper eyelids. Clinical examination revealed a papule on the right eyelid and a plaque measuring 0.5 × 1 cm on the left, both pearly white, firm, and non-tender. Dermoscopy showed whitish, flocculent areas with linear vessels. Excisional biopsy confirmed dermal calcium deposits with surrounding collagenous fibrosis, establishing the diagnosis. Serum calcium, phosphorus, and parathyroid hormone levels were normal. No recurrence was observed at 6 months. This case highlights the unusual bilateral and symmetrical presentation of eyelid SCNs and the role of dermoscopy in supporting the diagnosis.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...

The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
