Penile chestnut papules

Simply put, papules are the phenomenon that bacteria accumulate on the surface of the skin after the skin is infected. Papules are widely distributed in various parts of the human body, and sometimes occur in private parts, such as penile chestnut papules, which is a classic example. The shapes and colors of the papules are different. The occurrence of penile chestnut papules is the result of a combination of factors. Next, we will introduce the main symptoms of penile chestnut papules in detail.

Most of the sebaceous cysts are chestnut papules, which are small milky white or light yellow cysts. When pricked with a needle, small white lumps appear. It can happen to any age, any gender, and even newborns.

One of the causes is genetics, and the other is trauma. Milia caused by trauma often occurs after abrasions, scratches, or inflammatory rashes on the face. Another reason is that the skin secretes too much oil, which cannot be discharged normally, clogs the hair follicles and causes penile chestnut papules.

2. Secondary lesions are mostly distributed around the original skin lesions, can last for several years, and fall off naturally without scar formation.

3. Some lesions may have calcium salt deposits, which are as hard as cartilage and dark yellow as the lesions grow larger.

3. Clinical classification

1. Primary type: It occurs from newborns, is formed by undeveloped sebaceous glands, and the lesions can disappear naturally.

2. Secondary type: often occurs after inflammation and may be related to damage to the sweat ducts. It may occur after sunlight exposure, second-degree burns, epidermolysis bullosa, delayed cutaneous epidermal hyperplasia, lichen planus, vesicular dermatitis, perianthia, perianthoides, and X-ray exposure.

3. Pathological diagnosis

Histopathology showed an epidermoid cyst, the cyst wall was composed of multiple layers of squamous epithelial cells, and the cyst cavity was filled with keratinocytes arranged in concentric circles.
