Introduction
In general, black spots growing under the skin and within the tissue may be related to factors such as trauma, pigmented nevi, folliculitis, hemangioma, or plantar warts. Patients are advised to follow medical instructions for symptomatic treatment. Additionally, such spots may also be associated with conditions like flat warts or melanoma. If patients experience any discomfort or symptoms, it is recommended to seek timely medical evaluation at a hospital to avoid delaying diagnosis and treatment.
Under normal circumstances, black spots appearing under the skin and embedded in the flesh may be related to factors such as trauma, pigmented nevi, folliculitis, hemangioma, or plantar warts. Patients are advised to follow medical advice for symptomatic treatment. Specific analysis is as follows:
1. Trauma
If the area with the black spot has experienced pressure or impact, it may cause rupture of subcutaneous capillaries, leading to blood accumulation. This can result in dark purple or black spots or patches under the skin, often accompanied by pain. Patients may take medications such as Sanqi Capsules or Xuefu Zhuyu Capsules as directed by a physician.
2. Pigmented Nevus
A pigmented nevus is a benign skin tumor originating from melanocytes. The exact cause is unknown but may be related to genetic or developmental factors. It can occur anywhere on the body and may appear brown, tan, bluish-black, or black. Pigmented nevi on the soles of the feet are frequently subjected to friction and irritation. Generally, they do not cause itching or pain and may not require special treatment. If desired for cosmetic reasons, they can be removed under medical guidance using methods such as laser therapy or liquid nitrogen cryotherapy.
3. Folliculitis
Clinically, after the onset of folliculitis, secretions may accumulate at the hair follicle site, causing metabolic abnormalities that could lead to the aforementioned symptoms. Under medical supervision, patients may use medications such as Doxycycline Capsules, Clarithromycin Capsules, or Mupirocin Ointment for treatment.
4. Hemangioma
Hemangioma refers to a benign tumor arising from vascular endothelial cells. The skin may show bruising, purpura, nodules, or papules that resemble small black spots. Patients may follow medical advice to use medications such as Propranolol Hydrochloride Tablets, Prednisone Acetate Tablets, or Dexamethasone Tablets.
5. Plantar Wart
Caused by infection with the human papillomavirus (HPV), it can spread through minor breaks in the skin. It appears as yellowish or brownish callus-like plaques or flat papules with a rough surface. After removing the keratinized layer, small black dots formed by ruptured capillaries bleeding into the area become visible, resembling black spots embedded in the subcutaneous tissue. Patients may use topical medications such as Fluorouracil Cream, Imiquimod Cream, or Cantharidin Cream as prescribed.
In addition, other possible causes include flat warts or melanoma. If patients experience any discomfort, they should promptly seek medical attention at a hospital to avoid delays in diagnosis and treatment.
