Summary
Subungual elastofibroma, a rare connective tissue nevus, can occur in the nail bed. This case highlights an unusual presentation of this benign tumor on the big toe.
Area of Science:
- Dermatopathology
- Connective tissue disorders
- Nail bed pathology
Background:
- Cutaneous elastofibroma is a rare benign tumor.
- It is classified within the connective tissue nevus complex.
- Subungual involvement is exceptionally uncommon.
Observation:
- A patient presented with a unique subungual elastofibroma on the big toe.
- The lesion was surgically excised.
- Histopathological examination revealed a tumor densely packed with fine elastic fibers.
Findings:
- The tumor demonstrated a significant abundance of fine elastic fibers.
- The relationship between these fibers and oxytalan and elaunin fibers was analyzed.
- A potential connection to the onychodermis was explored.
Implications:
- This case expands the known clinical spectrum of cutaneous elastofibroma.
- Understanding the unique fiber composition may offer insights into tumor development.
- Further research could clarify the association with the onychodermis and nail disorders.

Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

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

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
