Papillary hidradenoma, also known as nodular hidradenoma, is a rare, benign (non-cancerous) tumor that originates from sweat glands. These tumors typically appear as small, firm lumps under the skin and are most commonly found on the head, neck, or extremities. Although generally harmless, they can sometimes become symptomatic or recur after removal.
Pathophysiology
Structure
Papillary hidradenomas are composed of cells resembling those of sweat glands. They form well-defined nodules that may be single or multiple. The tumors are usually slow-growing and encapsulated, making surgical removal straightforward.
Blood Supply
These tumors receive blood through small blood vessels in the surrounding tissue. Adequate blood supply is essential for tumor growth and maintenance.
Nerve Supply
Papillary hidradenomas are innervated by small nerve fibers, which can cause sensations like tenderness or pain if the tumor enlarges or becomes inflamed.
Types of Papillary Hidradenoma
While papillary hidradenoma is generally considered a single entity, variations can occur based on location, size, and cellular characteristics. However, no widely recognized subtypes exist.
Causes
Papillary hidradenoma is sporadic, meaning it typically occurs without a clear cause. However, potential factors include:
- Genetic mutations
- Family history of sweat gland tumors
- Chronic skin irritation
- Previous skin trauma
- Exposure to radiation
- Hormonal imbalances
- Immune system dysfunction
- Certain genetic syndromes
- Aging skin
- UV radiation exposure
- Skin infections
- Obesity
- Diabetes
- Smoking
- Exposure to chemicals
- Stress
- Poor hygiene
- Allergic reactions
- Hormone replacement therapy
- Unknown environmental factors
Symptoms
Individuals with papillary hidradenoma may experience:
- Small, firm lumps under the skin

Medications (Drugs)
While medications are not the primary treatment, they may assist in managing symptoms or preventing recurrence:
- Antibiotics: If infection occurs post-surgery.
