Why Are There Many Dense Small Dots on My Lower Legs?
The presence of many dense small dots on the lower legs may be related to diseases such as folliculitis, keratosis follicularis, contact dermatitis, and allergic purpura. The treatment measures should be determined based on the cause, as detailed below:
1. Folliculitis
The main clinical symptom of folliculitis is red papules centered on the hair follicles. Therefore, if folliculitis occurs on the lower legs, there will be many dense small dots locally. For folliculitis caused by bacterial infection, topical medications such as mupirocin ointment and erythromycin ointment can be used for treatment. If it is caused by fungal infection, topical medications such as terbinafine cream and ketoconazole cream can be used. The prognosis of folliculitis is good, so there is no need to worry too much. In daily life, attention should be paid to maintaining personal hygiene, but the frequency of cleaning should not be too high.
2. Keratosis Follicularis
Keratosis follicularis is a hereditary skin disease characterized by abnormal keratinization, which can lead to multiple needle-sized to pea-sized papules on the skin. Papules often occur on the face, chest, abdomen, legs, arms, and other parts of the body, sometimes resulting in many dense small dots on the lower legs. Patients can use topical medications such as tretinoin cream and salicylic acid cream for treatment, which can help improve papule symptoms. Laser and cryotherapy are also treatment options that can alleviate papule symptoms. The prognosis of keratosis follicularis is good. Patients should bathe regularly and change clothes frequently. After bathing, they can apply body lotion appropriately to prevent skin from drying and cracking.
3. Contact Dermatitis
If the lower legs come into contact with animal fur, catkins, toxic chemicals, etc., it may cause contact dermatitis, papules, or papules, manifesting as many dense papules on the lower legs. Patients can use topical medications such as calamine lotion and mometasone furoate cream for treatment. If topical medications are ineffective, oral medications such as loratadine and cetirizine can be used. It is also important to avoid contact with allergens to prevent recurrent episodes.
4. Allergic Purpura
Allergic purpura is a vascular allergic disease that can be accompanied by capillary dilation. Clinically, it manifests as local subcutaneous bleeding points and skin ecchymosis, resulting in many dense small spots on the lower legs. Patients with allergic purpura should actively seek and remove the causative factors. At the same time, anti-allergic medications such as loratadine and montelukast sodium can be used for treatment. If accompanied by joint pain, medications such as ibuprofen and acetaminophen can be used for relief. During severe disease flares, any physical activity is prohibited, and only after the condition stabilizes can appropriate exercise be performed.
