Erythema Induratum
Bazin Disease

Erythema induratum represents a chronic skin disease most often caused by Mycobacterium tuberculosis, consisting of chronic inflammatory nodules commonly located on the lower limbs of the patient. Similarities exist between this condition and nodular vasculitis, but at this time the two are considered separate entities.

Presentation

Erythema Induratum (EI) more often affects middle-aged women [1], but men and children can also acquire this illness.

An EI case usually suffers from pulmonary tuberculosis, but other sites of infection, like cervical lymphadenitis [2], renal parenchyma [3], epididymo-orchitis [4] or aortic valvular lesions of the same etiology [5] are possible. One study [6] even describes EI after Bacillus Calmette–Guérin (BCG) vaccine administration. In addition, it is important to evaluate the existence of human immunodeficiency virus (HIV) concomitant infection clinical traits [7].

The patients show erythematous or violaceous nodules, 1 - 4 cm in size, or plaques with a scaly surface located on the lower limbs, that may be tender and have a recurrent character, reappearing once every 3 or 4 months. Nodules sometimes cause shallow ulcers that heal, leaving scars and hyper pigmented areas. The affected regions, like calves, ankles, thighs, buttocks, but also trunk and arms are edematous. Disseminated forms have been described [8]. Pruritus is absent. The disease may worsen with cold weather. The clinical picture may be completed by the presence of distal painful peripheral neuropathy [9], cutis marmorata or erythrocyanosis. Systemic complaints are usually absent, but other dermal manifestations of tuberculosis, such as papulonecrotic tuberculids may coexist.

  • Inflammation

    Additional workup did not indicate any other conditions including latent tuberculosis. 1, 2 Fig 1: Healed lesions on the posterior aspect of leg Fig 2: Skin biopsy (subcutaneous fat): a- Inflammation of fat lobules; b- Inflammation of septae; c- Inflammation [chanrejournals.com]

    Both groups showed varying combinations and degrees of acute and chronic inflammation, coagulative and caseation-like necrosis, and granulomatous inflammation. [ncbi.nlm.nih.gov]

    The vasculitis is of the larger vessels with panniculitis - an inflammation involving subcutaneous fat and occasionally muscle, with or without vasculitis. [patient.co.uk]

    However, vaccine risks include complications, such as subcutaneous abscesses including EIB, localized or generalized cutaneous tuberculids, local inflammation, fever, and spread of TB to distant organs. [unboundmedicine.com]

    The exact cause is unknown but the patchy inflammation in the blood vessels and lymphatics in the deep dermis and subcutaneous fat appears to relate to a slowed circulation. [americandragon.com]

    Often there are also systemic symptoms, including chills, fever, headache, vomiting, backache, and stiff neck. [medical-dictionary.thefreedictionary.com]

    She reported minimal coughing and a 25-lb weight loss over the last year, but she denied night sweats, fever, or chills. Figure 1. Disseminated erythema induratum in a patient with a history of tuberculosis. [mdedge.com]

    Key symptoms include chest pain, chills, chronic cough, fatigue, fever, hemoptysis, night sweats, and weight loss. Individuals may also have abnormal chest radiography or a positive sputum smear or culture [14]. [cureus.com]

Skin

  • Erythema

    Erythema Induratum of Bazin Nodular Vasculitis Currently, the terms erythema induratum of Bazin and nodular vasculitis are used as synonyms by most authors to describe the most common form of lobular panniculitis with vasculitis. [dermaamin.com]

    Erythema Induratum of Bazin is a topic covered in the 5-Minute Clinical Consult. [unboundmedicine.com]

    DISCUSSION Erythema induratum is synonymous with nodular vasculitis. [nursingcenter.com]

    Therefore, erythema induratum/nodular vasculitis complex is classified into 2 variants: erythema induratum of Bazin type and nodular vasculitis or erythema induratum of Whitfield type. [emedicine.com]

  • Ulcer

    Usually, subcutaneous nodules become adherent to the skin surface, ulcerate, and then heal with scarring. [dermaamin.com]

    The nodules may ulcerate with bluish borders, and cold weather may be the precipitating factor. [patient.co.uk]

    There are very few cases of EIB presenting as annular plaques.[3] Nodules generally ulcerate in EIB, but in this case, the nodules did not ulcerate. [e-ijd.org]

    2004 in Revista do Instituto de Medicina Tropical de Sao… Erythema induratum of Bazin is a disease that usually affects women, in whom erythematous subcutaneous nodules and plaques appear on the posterior part of the lower extremities, some of which ulcerate [semanticscholar.org]

    They break down to form small and multiple ulcers. Fresh crops of nodules appear in periphery of ulcer and ultimately break down. [ipfs.io]

  • Skin Lesion

    The histopathology of the skin lesion was suggestive of erythema induratum. She had complete resolution of her skin lesions and fever following 6 months of treatment with antitubercular drugs. [ijmyco.org]

    The skin lesions showed improvement at one month and remitted mostly at two months. After 6 months, the skin lesions have subsided and no obvious side effects were observed. [ncbi.nlm.nih.gov]

    Some skin lesions showed superficial ulcers on deep skin atrophy covered with crusts and scales (Figure 1). [dovepress.com]

  • Eruptions

    Papulonecrotic tuberculid occurs predominantly in young adults and is characterized by eruptions of necrotizing papules that heal with varioliform scars. [ncbi.nlm.nih.gov]

    The conditions in the complex are characterized by the sudden onset of a reddened macular, bullous, papular, or vesicular eruption, the characteristic lesion being the iris, bull's eye, or target lesion, which consists of a central papule with two or [medical-dictionary.thefreedictionary.com]

  • Subcutaneous Nodule

    Usually, subcutaneous nodules become adherent to the skin surface, ulcerate, and then heal with scarring. [dermaamin.com]

    On physical examination, multiple deep subcutaneous nodules were scattered on the bilateral lower extremities. There was a hyperpigmented patch overlying a crop of nodules on the left calf ( Figure 1 ). [nursingcenter.com]

    nodules and plaques appear on the posterior part of the lower extremities, some of which ulcerate. [semanticscholar.org]

    Subcutaneous nodule histology was compatible with erythema induratum of Bazin, and liver biopsy evidenced granulomatous hepatitis. [ncbi.nlm.nih.gov]

    Bazin disease - recurrent, hard, subcutaneous nodules that frequently break down and form necrotic ulcers, usually on the calves; lesions are sterile and probably a form of nodular vasculitis. [medical-dictionary.thefreedictionary.com]

Workup

Workup should include a complete cell blood count with differential, inflammatory markers (such as the erythrocyte sedimentation rate) and liver function tests. M. tuberculosis infection can be diagnosed in may ways: interferon-gamma release assays [10] such as QuantiFERON--tuberculosis (TB) Gold In-Tube test and the T-SPOT-TB test [11]. The manifestation of pathognomonic lesions and a positive QuantiFERON exam establish the diagnosis, even if acid-fast bacilli are not detected or the thoracic radiography is normal [12]. The purified protein derivative tuberculosis skin test is positive in these patients and an exaggerated host immunologic response and hypersensitivity reaction are to be expected after administration. In case an underlying active disease is suspected, the physician should order urine, early morning sputum, and gastric aspirates microbiological examination.

Imaging modalities include thoracic radiographs (posteroanterior and lateral) that may show aspects of active or inactive tuberculosis. If the diagnosis cannot be established otherwise, an excisional biopsy should be done. The tissue will then be analyzed using hematoxylin-eosin, specific stains for acid-fast bacilli, but also for bacteria and fungi. In cases with negative tuberculosis findings, hepatitis C and HIV infection should be searched for. Furthermore, a histological analysis will depict a granulomatous panniculitis with possible inflammatory vasculitis [13], noncaseating granulomas and caseation-like necrosis. Other cell types, like giant, epithelioid cells or histiocytes are also encountered in late stages, while fresh lesions mainly contain lymphocytes. The presence of M. tuberculosis deoxyribonucleic acid in the excised tissue can be proven using polymerase chain reaction [14]. However, its absence does not confirm the non-existence of the ailment.

Treatment

Potassium iodide is also an effective and rapid treatment for erythema induratum of Bazin. [dermaamin.com]

After treatment of any identified potential etiologies, therapeutic options are similar for both EIB and EN, which are forms of panniculitis. [unboundmedicine.com]

One patient had concurrent active pulmonary tuberculosis, and the other had a history of previous treatment for pulmonary tuberculosis. The treatment regimen for these patients is outlined. [ncbi.nlm.nih.gov]

We plan to continue the treatment for another 3 months, and follow-up the patient thereafter. During the course of treatment, no side-effects such as nausea and vomiting were observed. [journals.lww.com]

Prognosis

In non-tuberculous type (Whitfield type), treatment of the associated (underlying) condition is necessary The prognosis of Erythema Induratum is good in a majority of cases. [dovemed.com]

Prognosis The prognosis is good if treated properly. To date, no fatal cases of erythema induratum have been reported. However, the chronic, recurrent, painful nodules and resultant scarring can be a source of significant morbidity. [emedicine.com]

Prognosis If TB is the cause, the lesions will disappear with appropriate TB treatment. Spontaneous resolution of lesions is common within a few months, leaving areas of postinflammatory hyperpigmentation and atrophic scarring. [patient.co.uk]

Etiology

Some investigators, however, prefer to retain the name erythema induratum of Bazin for those cases in which an etiologic relationship with tuberculosis is demonstrated and refer to the remainder of cases as nodular vasculitis. [dermaamin.com]

After treatment of any identified potential etiologies, therapeutic options are similar for both EIB and EN, which are forms of panniculitis. [unboundmedicine.com]

In many countries, tuberculosis is still the main etiologic factor. We report a case of a 40-year-old woman who presented a course of protracted and recurrent episodes over five years of cutaneous lesions on her legs. [semanticscholar.org]
