We have read the interesting paper by Schneider and Jordaan on the histopathology of 20 cases of erythema induratum of Bazin (1); this article was a continuation of another one by Schneider et al. on the detection of Mycobacterium tuberculosis DNA in the same lesions of the same cases which was also published in The American Journal of. Erythema induratum General. Features: Uncommon. Etiology: unknown. Brinster suggests an association, in some cases, with Mycobacterium tuberculosis and hepatitis C. Clinical: Classic location: posterior shins. Ulcerates and scars. Microscopic. Features: Predominantly lobular process with: Necrotizing granulomatous inflammation Response to anti-TB was dramatic in all cases. Clinical findings were similar to those previously published. We emphasize the simultaneous occurrence of erythema induratum, associated Takayasu's disease, possible associated phlebitic tuberculid, and clinical mimicry of acute bacterial endocarditis . Slowing of the flow in the deep vessels can also encourage deposition of bacteria from the bloodstream, including tubercle bacilli, and in some patients, nodular vasculitis is a sign of tuberculosis, when it may be called erythema induratum or Bazin disease Erythema induratum (EI) is an uncommon inflammatory disorder with alterations centered upon the subcutaneous fat tissue (panniculitis). The term EI was first proposed by Ernest Bazin in the mid-19 th century, who recognized the association of the distinctive clinical and histologic changes with tuberculosis (TB) [ 1,2 ]

Erythema induratum (nodular vasculitis) is a related but distinctly different clinicopathologic reaction pattern of the subcutaneous fat. It is classically caused by an antigenic stimulus from Mycobacterium tuberculosis but may be associated with several other underlying disorders Erythema induratum is a panniculitis on the calves. It occurs mainly in women, but it is very rare now. Historically, when it has occurred, it has often been concomitant with cutaneous tuberculosis, and it was formerly thought to be always a reaction to the TB bacteria Nodular vasculitis (erythema induratum of Bazin) and thrombophlebitis can be clinically or pathologically mistaken for CPAN. 1, 2, 4 Nodular vasculitis is a lobular panniculitis and vasculitis affecting mostly venules or septal veins and less commonly arteries. 52 In contrast, CPAN is an arterial vasculitis with minimal extension of its.

An 81-year-old woman with a history of renal cell carcinoma and years of slowly, progressively enlarging pulmonary nodules of uncertain etiology presented with. Both patients were subsequently found to have malignant neoplasms. The parallel course of the neoplasia and the erythema induratum of Bazin in these 2 cases leads us to formulate the hypothesis that this pathology can sometimes manifest itself as a paraneoplastic syndrome Erythema induratum is characterized by painful, erythematous, sometimes ulcerating nodules on the lower legs that, histopathologically, show a lobular panniculitis.

The term erythema induratum (EI) was coined by Bazin in 1855, who described deep violaceous nodules on the posterior lower legs of young women.

Erythema induratum / nodular vasculitis A 29-year old Vietnamese woman was treated for erythema nodosum, but she actually had a condition called erythema induratum, which is associated with tuberculosis. EI isn't perfectly understood, but it might be a sensitivity reaction to tuberculosis antigens. (Chew et al, 2005 The diagnosis of erythema induratum should urge the clinician to search for a source of active tuberculosis, and treatment should be initiated accordingly. AB - The etiology of erythema induratum, a rare disease of the skin in the United States but occasionally seen in natives of Asian countries, remains a source of debate Based on a pathology assessment of hematoxylin and eosin-stained slides from 4-mm punch biopsy specimens, two cases were classified as erythema nodosum and 12 as erythema induratum of Bazin . Eight of the patients were tested for M. tuberculosis with QuantiFERON, seven of whom were positive (87.5%, 95% confidence interval, 46.7%-99.3%.
Enchondromas. Enchondromas are benign chondrogenic tumors composed of hyaline cartilage that typically occur in medullary cavity of the diaphysis or metaphysis, most commonly in the hands. Patients typically present between the ages of 20-50 with an asymptomatic lesion, discovered incidentally on radiographs Panniculitis 17. Erythema induratum is a panniculitis on the calves. (wikipedia.org)In 1945, Montgomery et al, while fully acknowledging the existence of tuberculosis-associated erythema induratum, coined the term nodular vasculitis to describe chronic inflammatory nodules of the legs that showed histopathologic changes similar to those of erythema induratum, that is, vasculitis of the larger.

In recent years, however, there seems to be a consensus considering erythema induratum of Bazin and nodular vasculitis as the same entity, 8,9 an opinion that we shared. 10 Like erythema nodosum, erythema induratum of Bazin is currently considered to be a reactive disorder related to several causative factors, one of which may be tuberculosis. Erythema induratum of Bazin - nodular vasculitis - is a mostly lobular panniculitis with vasculitis, which affects almost exclusively adult females. Considered in the past to be a cutaneous manifestation of tuberculosis, this pathology is now thought more likely to be the result of a cell-mediated immune response to various exogenous or.

When the lesions were present on her legs. Lyme disease is divided into three stages: early localized, early disseminated, and late. The early localized disease is distinguished by the red ring-like expanding rash of Erythema migrans at the site of a recent tick bite. Other symptoms experienced at this stage may be flu-like symptoms, malaise, headache, fever, myalgia, and arthralgia Erythema nodosum is the hallmark septal pannicullitis. While pathology can vary depending on the acuity of the lesion sampled, in nearly all cases of EN the septa are thickened and fibrotic, with an inflammatory infiltrate, which may spill over into the periseptal adipocytes (Figure 3) Erythema induratum of Bazin in an infant after Bacille Calmette-Guerin Vaccination Journal of Dermatology 33 : 268-272, 2006 CPC myopericytoma Visual Dermatology Vol.5 : 490-496, 2006 Infundibulocystic Basal Cell Carcinoma 1 60 : 744-746, 2006 60 : 808-810. 2006 2 00 5/14 2006.9.15 (B) 24(B)
Erythema nodosum (EN) is an inflammation of the subcutaneous fat characterized by painful, red swellings over the shins. The eruption may also involve the extensor aspects of the thighs and forearms. The condition is believed to be a delayed hypersensitivity reaction and occurs most often in women during their reproductive years [2, 3] Erythema nodosum is a type of panniculitis. Panniculitis occurs when there is inflammation of the layer of fat lying underneath the skin. The inflammation causes red rounded lumps (nodules) to form just below the skin surface, which are tender. Erythema nodosum most commonly affects both shins. Our picks for Erythema Nodosum Microbiological proof is the key to diagnosis and treatment, and tissue biopsy is frequently required. Other supportive findings are granulomas and positive AFB stain on pathology, and chest x-ray findings.
