Abstract:
We present an unusual case of combined nevus of the tarsal conjunctiva and eyelid margin in a pregnant woman who noticed morphological changes of the lesion during pregnancy. The patient underwent a wide full-thickness eyelid excisional biopsy including tarsal conjunctiva. Histopathologically, a subepithelial combined nevus (nevocellular and blue nevus) was observed. Conjunctival nevi are benign lesions with wide variation in clinical and histopathological features. Tarsal conjunctival involvement, as in the present case, is extremely rare (less than 1% of conjunctival nevi), especially the blue type nevus. Definitive diagnosis is possible only with excisional biopsy.

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.
