Introduction
Pigmented Tricholemmal Nevus: This condition predominantly affects males and is benign. It manifests as rough skin surfaces with coloration ranging from light to dark brown. Most patients are asymptomatic, though a minority may experience pruritus. Specific treatment is generally unnecessary; however, if the brown macules on the lower legs progressively increase in number, laser therapy or surgical excision may be considered.
An increasing number of brown spots on the lower legs may result from conditions such as hyperpigmentation, pigmented tricholemmal nevus, or seborrheic keratosis. It is advisable to seek prompt medical evaluation at a hospital to determine the underlying cause and receive appropriate treatment.
Why Are Brown Spots on the Lower Legs Increasing—and What Should Be Done?
Hyperpigmentation: This may be triggered by dietary factors, endocrine imbalances, electromagnetic radiation, or ultraviolet (UV) exposure from sunlight, leading to brown discoloration on the lower legs. In most cases, no specific treatment is required; maintaining a healthy diet and lifestyle, along with consistent sun protection, is usually sufficient.
Pigmented Tricholemmal Nevus: This benign condition occurs more frequently in males and presents as rough-surfaced skin lesions ranging in color from light to dark brown. Most patients are asymptomatic, though some may experience mild pruritus. Generally, no intervention is needed; however, if the brown spots progressively increase in number, laser therapy or surgical excision may be considered.
Seborrheic Keratosis: A common benign epidermal tumor, possibly associated with natural skin aging, genetic predisposition, or infection. Clinically, it manifests as slightly raised, flat, light-brown papules or plaques. Occasionally, affected areas may become pruritic or painful. While treatment is typically unnecessary, removal via cryotherapy, laser ablation, or surgical excision may be pursued if the brown spots continue to proliferate.
Maintain a light, balanced diet rich in vitamin-containing vegetables and fruits—such as tomatoes and kiwifruit.
