Causes of erythema induratum

It is believed that erythema induratum is a subcutaneous arteriovenous vasculitis that causes adiponecrosis. However, it is also believed that erythema induratum results from a local allergic reaction initially, followed by a delayed hypersensitivity reaction, caused by release of mycobacterium tuberculosis from the blood vessels What are the Causes of Erythema Induratum? (Etiology) The exact cause of Erythema Induratum is currently unknown. It is a type of nodular vasculitis that is caused by abnormal inflammation of the subcutaneous fat. On a tissue biopsy, the condition shows a pattern of lobular panniculitis, which is a microscopic findin

First described by Bazin, the rare entity of erythema induratum was thought to be of tuberculous origin or a tuberculid reaction. Opinion has varied, and some authors have classified this condition as a vasculitis involving subcutaneous vessels Infection with M tuberculosis is considered to be an etiologic factor for erythema induratum that is associated with tuberculosis (Bazin disease), and, based on published reports, latent or active.. Erythema induratum (also referred to as erythema induratum of Bazin (EIB) or nodular vasculitis) is a chronic nodular skin disease that is thought to represent a hypersensitivity response to Mycobacterium tuberculosis or its antigens However, even when cultures for tuberculosis are negative, molecular evidence suggests that at least some cases of erythema induratum are due to a hypersensitivity reaction to fragments of mycobacterial organisms, as demonstrated by polymerase chain reaction (DNA) analysis in lesional tissue. 23 Erythema induratum of Bazin should be considered as a separate entity of nodular vasculitis caused by latent foci of tuberculous infection.

Erythema Nodosum - Causes, Symptoms and Treatment | Health

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 ] Hypertension (high blood pressure). 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 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. It is now considered a panniculitis that is not associated with just a single defined pathogen. The medical eponym Bazin disease was historically synonymous, but it applies only to the tuberculous form and is dated Erythema induratum, which is associated with tuberculosis; Erythema infectiosum (also called the Fifth disease), which is commonly caused during childhood The causes of erythema vary in.

Panniculitides encompass a great number of different entities; however, once a vasculitis has been detected histopathologically within the subcutaneous tissue, the differential diagnosis is mainly restricted to polyarteritis (panarteritis) nodosa (PAN), nodular vasculitis (NV), and Bazin's erythema induratum (EI) Nodular vasculitis/erythema induratum in which ulcerated, draining nodules affect the posterior calves Lipodermatosclerosis , which is a consequence of venous insufficiency Infection of the subcutaneous fat with bacteria , mycobacteria or fungi , which may cause ulcerated, fluctuant, and draining abscesse

Histopathology of erythema induratum often reveals lobular panniculitis with granuloma formation, vasculitis, and necrosis. Although it is generally believed that a delayed-type hypersensitivity reaction to TB is the most common underlying cause of erythema induratum, other etiologies may also exist Examples of nontuberculous causes include infections such as Nocardia, Pseudomonas, Fusarium, or other Mycobacterium species. 10 Medications such as propylthiouracil also have been implicated. 11 The classification of erythema induratum as a tuberculid suggests that the nodules are a reaction pattern rather than a primary infection, though the.
