Summary
Colloid milium, a rare skin condition, involves amorphous material deposition. This case highlights its coexistence with chronic actinic dermatitis, both triggered by sun exposure, in a patient with an outdoor occupation.
Area of Science:
- Dermatology
- Histopathology
- Dermatoses
Background:
- Colloid milium is a rare, underdiagnosed skin condition characterized by dermal amorphous material deposition.
- Diagnosis is confirmed via histopathology showing colloid in dermal papillae.
- Typically affects sun-exposed areas like hands, neck, and ears.

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.

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...
