Atypical Lichen Myxedematosus
Atypical Lichen Myxedematosus (pronunciation: a-typ-i-cal li-chen myx-e-de-ma-to-sus) is a rare variant of Lichen Myxedematosus, a chronic skin disorder characterized by papular and sclerodermoid lesions.
Etymology
The term 'Atypical Lichen Myxedematosus' is derived from the Greek words 'atypikos' meaning not typical, 'leichen' meaning tree moss, 'myxa' meaning mucus, and 'edema' meaning swelling. The term 'myxedematosus' refers to the mucin deposition that is characteristic of this condition.
Symptoms
Atypical Lichen Myxedematosus is characterized by the presence of firm, waxy papules and plaques on the skin. These lesions are typically distributed symmetrically on the body. The skin may also appear thickened and hardened, a condition known as sclerodermoid.
Causes
The exact cause of Atypical Lichen Myxedematosus is unknown. However, it is believed to be an autoimmune disorder, where the body's immune system mistakenly attacks its own skin cells.
Diagnosis
Diagnosis of Atypical Lichen Myxedematosus is typically made based on the clinical presentation of the skin lesions. A skin biopsy may also be performed to confirm the diagnosis and rule out other conditions.
Treatment
Treatment for Atypical Lichen Myxedematosus is aimed at managing the symptoms and may include topical corticosteroids, systemic corticosteroids, and immunosuppressive drugs. In severe cases, plasmapheresis may be considered.
