Tumid lupus erythematosus

Tumid lupus erythematosus is a rare and less severe subtype of lupus erythematosus, a chronic autoimmune disease. It is characterized by erythematous, edematous, non-scarring plaques on sun-exposed skin, without systemic involvement.

Signs and Symptoms

Patients with tumid lupus erythematosus typically present with single or multiple erythematous, edematous, and non-scarring plaques. These plaques are often located on sun-exposed areas of the skin, such as the face, V area of the neck, and the upper trunk. The plaques may be asymptomatic or associated with mild pruritus.

Causes

The exact cause of tumid lupus erythematosus is unknown. However, it is believed to be an autoimmune disorder, where the body's immune system attacks its own cells and tissues. Exposure to sunlight may trigger the condition in susceptible individuals.

Diagnosis

The diagnosis of tumid lupus erythematosus is based on clinical features, histopathological findings, and the absence of systemic involvement. A skin biopsy is often performed to confirm the diagnosis.

Treatment

Treatment of tumid lupus erythematosus primarily involves avoiding sun exposure and using sun-protective measures. Topical corticosteroids and antimalarial drugs, such as hydroxychloroquine, may also be used.

Prognosis

The prognosis for tumid lupus erythematosus is generally good, as it does not typically progress to systemic lupus erythematosus or cause scarring. However, regular follow-up is necessary to monitor for potential development of systemic disease.
