Abstract:
Clear cell fibrous papule (FP) is a rare variant of FP. We report a 39-year-old female patient who presented with a dome-shaped papule on the nose. The diagnosis of clear cell FP was made based on histological and immunohistochemical studies. Interestingly, scattered S-100 cells were admixed within the lesion, a finding hitherto not reported. The S-100 positivity may be misleading and should be cautiously interpreted.

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 and...
