What does lupus erythematosus mean

This period was marked by the discovery of the LE cell in 1948 when researchers discovered these cells in the bone marrow of patients with acute disseminated lupus erythematosus.

This progression of discovery paved the way for the application of immunology to the study of lupus. Today’s treatments are founded on these findings.

In the United States depending on race, anywhere between 20 and 150 per 100,000 women develop lupus.   In the United States, lupus is most common among African Americans. Interestingly, the prevalence of lupus among Africans may be much lower than in African Americans.

Wolf Spider Bite Treatment: Home Remedies and Prevention

We present a case of 38-year-old female patient who presented with a persistent hyperpigmented, erythematous, thickened scaly plaque over the nose for the past six years. The lesion aggravated upon exposure to sun. She also had history of recurrent swelling and redness of fingers during the winter season. Examination revealed a solitary hyperpigmented and erythematous plaque of 3×2 cm with overlying adherent scales [ Figure 1 ]. She did not have any associated complaint and there were no similar lesion anywhere else on the body. Her routine biochemical investigations were within normal range. Anti nuclear antibody and Rheumatoid Arthritis factor was negative. Venereal disease research laboratory was also non-reactive. Skiagram of chest was found to be normal. Eye examination did not reveal any abnormality. A skin biopsy done from the lesion over the nose showed atrophy of the epidermis, keratotic plugging, vacuolar degeneration of the basal layer, and dense lymphomononuclear cells infiltrate in the superficial dermis [Figures ​ [Figures2a 2a and ​ andb]. b ]. Biopsy results were consistent with pathological findings of DLE. She was advised to avoid sun exposure and to reduce stress and fatigue. She was given Hydroxychloroquine tablets 200 mg twice a day. Topical steroids were given for the lesion over the nose. She was given oral calcium channel blocker (nifedipene) for chilblains. Keeping in view the socioeconomic status of the patient and high cost of the drug, thalidomide could not be prescribed. In due course of time and on regular follow-up, we noticed similar new lesions in the triangular fossa and helix of her bilateral ears. She was continued with the same treatment and was advised to be on regular follow-up. As is found in this country the patient got lost to follow-up but arrived one day after 3 years complaining that the lower portion of her left ear was gradually getting eroded and mutilated. On examination, the lobule and adjacent lower portion of helix of her left ear were found to be mutilated and were studded with erythematous scaly lesions on the margins. Similar changes were also observed on the right ear. Her repeat biopsy from the margin of mutilated lobule, showed changes similar to what were seen on the DLE lesion, but the infiltrate extended to the subcutaneous fat favoring the diagnosis of lupus panniculitis. Prognosis was explained to the patient and her relatives. An opinion of plastic surgeon was also taken for the possibility of reconstructive surgery. The term “lupus” means “wolf” in Latin, and is attributed to Physician Rogerius Frugardi (1230 AD). It was probably thought that the damage caused by the disease resembled the result of an attack by a ravenous wolf.[2] Atrophy, liquefaction degeneration, oedema, hyalinization of connective tissue, marked lymph mononuclear cell infiltration are characteristically found in histology of DLE, such infiltration may have involved the skin with its appendages, subcutaneous tissue and vessels in the dermis and underlying cartilages of ears.[3,4] Same mechanism of dermal and subcutaneous necrobiosis with some element of vasculitis might have played leading to mutilation and deformity in our case. In 70% of patients with lupus panniculitis there will be either preceding, subsequent, or concomitant lesions of DLE. It is a chronic condition that often involves persistent lesions that subsequently heal with disfigurement.[5] Extensive literature search failed to reveal this type of mutilation involving ear lobule. The aim of reporting this case is to make dermatologists aware of this cosmetic and physical disfigurement so that timely prevention and treatment can be undertaken accordingly. This case is being reported for its rare presentation showing mutilating changes in the lesion of DLE. To conclude, rare complications like Squamous cell carcinoma and mutilative changes should always be kept in mind.

Author information

The history of lupus is divided into three periods.

This period was marked by the first description of the cutaneous disorder; it is also when the term “lupus” was coined. Thirteenth Century physician Rogerius thought that facial lesions caused by the disease looked like wolf bites, hence the name “lupus” that means wolf in Latin.
