Sarcoidosis, an inflammatory condition, has the potential to impact different organs, with the lungs and lymph nodes being the most commonly affected. The exact cause of sarcoidosis remains unknown. Inflammation of an organ can lead to the development of lumps or nodules called granulomas. These clusters of immune system cells can disrupt organ function and alter its natural structure. The symptoms of sarcoidosis differ based on the affected organ, often leading to misdiagnosis.
Understanding Swollen Lymph Nodes
When your lymph nodes become swollen and enlarged, it typically means that your immune system is actively combatting an infection. However, in the case of sarcoidosis, the nodes themselves may be directly impacted. Specifically, lymph nodes located in the neck, armpits, and groin may enlarge when inflamed, resulting in tenderness and redness of the overlying skin. Sarcoidosis can also affect other lymph nodes, such as those in the chest and around the lungs, which can lead to discomfort and persistent coughing.
Red Patches or Bumps
In about 25% of cases, sarcoidosis can affect the skin, resulting in the development of skin lesions. These lesions often appear at the time of diagnosis. One common symptom is the presence of rash-like red bumps on the skin, which can feel warm to the touch. Typically found on the shins and ankles, these tender areas can cause significant discomfort. The size and shape of the bumps can vary greatly, sometimes resembling an allergic reaction. Additionally, sarcoidosis may cause certain sections of the skin to become either lighter or darker than the person’s natural skin tone.
