The difference between sweat gland tumor and sweat duct tumor is reflected in the definition, clinical manifestations, and treatment.
1. Definition: Sweat gland tumor is a kind of misshapen tumor originating from the sweat glands of the skin. Histopathological examination of skin lesions shows nodular dermal tumors with clear boundaries, some of which are attached to the epidermis. Sweat duct tumor is a benign tumor involving the ducts of sweat glands with unknown etiology.
2. Clinical manifestations: sweat gland tumor lesions are single intradermal or subcutaneous solid or cystic nodules, 0.5-3cm in diameter, sometimes with surface ulceration and plasma-like exudation. Sweat duct tumor lesions are normal skin color, yellowish or tawny hemispherical or flat papules, often without conscious symptoms.
3. Treatment: Sweat gland tumor is a benign tumor, surgical excision can be cured. Sweat duct tumor generally does not need treatment, and laser treatment or surgical excision can be used when it affects aesthetics or itching seriously.
Sweat gland tumor and sweat duct tumor are both tumors originated from sweat gland structure, and the difference between the two can be identified from the above aspects.
