What are the black spots under the armpit?
Generally, black spots appearing under the arms may be caused by conditions such as tinea versicolor, blackheads, or sebaceous cysts, and specific diagnosis should be based on individual circumstances. Detailed explanations are as follows:
1. Tinea Versicolor
Tinea versicolor is a common skin pigmentation disorder that typically presents as black or brown spots in areas such as the armpits, neck, and waist. It can be effectively treated with topical medications such as compound sulfur cream or sertaconazole nitrate cream, as directed by a physician.
2. Blackheads
Due to excessive sebum production, over-keratinization occurs at the opening of hair follicles, causing enlarged pores and a visible black spot at the center. Treatment may include topical application of adapalene gel or tretinoin ointment, as prescribed by a doctor.
3. Sebaceous Cyst
If the spot is a raised bump with a black dot on the surface from which oxidized keratinous material can be expressed, it is likely a sebaceous cyst. In most cases, surgical excision is the recommended treatment option.
In addition, acanthosis nigricans could also be a possible cause. If the black spots persist for a prolonged period or are accompanied by other symptoms, timely medical consultation is advised for accurate diagnosis and treatment by a qualified healthcare professional.
