The presence of powdery tumors in the neck is usually asymptomatic, except for small localized dark spots, including small bumps under the skin, which are the most significant aspect. When secondary infection occurs, localized redness and swelling, sometimes accompanied by pressure pain, are the most important symptoms. If the resistance of the body is low or if folliculitis is secondary, the infection of the powdery tumor will be formed and the redness, swelling and pain will appear at this time, which is also rare in clinical practice. In terms of treatment, local excision can be done, and attention should be paid to regular life and a healthy diet to regulate the symptoms of the vegetative nervous system, including a light diet, early to bed and early to rise, and other healthy lifestyles, which can effectively regulate the secretion of sebaceous glands and reduce the chances of its recurrence.
