In infants and young children, primary infection is usually asymptomatic or produces an acute illness that is often not recognized as being due to EBV. It has a well-established oncogenic potential, and has been implicated in the pathogenesis of various autoimmune diseases. Here is reported the case of a 32-months old boy, who presented with a history of two days of low-grade fever, pain in both legs, swollen ankles and inability to walk. On physical examination, the child appeared moderately ill, without fever. On both shins were observed nodules 2 - 3 cm in diameter, red to bluish in color, firm and poorly demarcated. Clinically, a diagnosis of Erythema nodosus was performed. Laboratory examinations revealed increased inflammatory parameters. After a full workup, EBV was established as the causative agent. Erythema nodosum is the most common form of panniculitis in children;however, it is relatively uncommon in the pediatric population. It is a self-limited disease, and most of infectious origin in children. Although uncommon, EBV infection is a potential cause of pediatric erythema nodosum.展开更多

Rare cases of EN caused by COVID-19 were recently reported but none due to COVID-19 vaccines were documented. We report here a case of EN occurring after COVID-19 vaccination. Patient presented with painful nodular lesions of all 4 limbs, evolving for one month. These lesions appeared 48 h after the second dose of COVID-19 vaccination. The patient reported no recent infectious episodes. The physical examination found numerous, erythematous dermohypodermatitis knots with no palpable adenopathy. Some were regressive according to biligenesis shades. Biology and radiology findings eliminated other common causes of this dermatosis. The skin biopsy was done and suggested EN. The final diagnosis was post COVID-19 vaccine EN. Patient received a symptomatic treatment and had a slight improvement of the lesions 10 days after diagnosis. Physicians should be aware of the side effects of the vaccine including skin manifestations, especially since more people are bound to be vaccinated.展开更多

Three weeks later, the mass had increased and polyarthritis and erythema nodosum had developed in both legs. A core needle biopsy led to a diagnosis of granulomatous mastitis with arthritis and erythema nodosum. Low-dose prednisolone (10 mg) rapidly improved the arthritis and the erythema nodosum. Granulomatous mastitis is a very rare, chronic inflammatory disease and only nine patients with granulomatous mastitis with erythema nodosum have been described. We reviewed the literature to determine the clinicopathological features and treatment of granulomatous mastitis. Appropriate diagnosis and steroid therapy should result in excellent outcomes.展开更多

Analysis of the presenting clinical features was done to determine the risk factors for ENL.Chi square and student t test was used for statistical analysis.Level of significance was set at 0.05.Results:ENL was present in 40%patients,all with lepromatous leprosy(LL).Clinical features that were seen more frequently in patients developing ENL include earlobe thickening(100%cf.25%,P =0.00),loss of the lateral third of the eyebrows(75%cf.16.7%,P=0.02) and mean bacteriology index(BI)(5.1 cf.2.9,P=0.03) and mean morphological index(MI)(17.8 cf.7.0,P =0.02).Number of thickened nerves(mean 2.5 cf. 1.4,P = 0.12),number of skin lesions(mean 19.4 cf.10.9,P = 0.15) and duration of illness(mean 15. 3 cf.12.8 months,P =0.68) did not predict ENL development.Conclusion:Finding LL patients with thickened earlobes,loss of lateral third of the eyebrow,high BI and MI should alert treating clinician to the possibility of ENL in a non endemic leprosy area.展开更多

Here, we report the case of a patient with repeated erythema nodosum associated with subareolar abscesses. The patient was a 34-year-old woman with painful erythematous nodules on her right shin, accompanied by an indurated lesion on her right breast 4 days before the onset of the nodules. Therefore, the patient underwent circumareolar incision, and consequently the painful erythematous nodules disappeared. However, after 39 days, the patient developed another tender, painful lesion in her right breast and painful erythematous nodules on her right shin. After another circumareolar incision, the painful erythematous nodules disappeared again. Therefore, we suggested a significant association between erythema nodosum and breast abscess in this patient. The most common underlying causative organism in breast abscess is Staphylococcus aureus;however, erythema nodosum has rarely been proven to be associated with staphylococcal infections. Therefore, the relationship between S. aureus and erythema nodosum is rather controversial. However, the resistance to the usual treatment methods and prolonged clinical course in our case suggest that the pathogenesis of erythema nodosum associated with breast abscesses might be different from that of the common form of erythema nodosum.展开更多
