ReferencesEritema nodoso é o tipo mais comum de paniculite, caracterizado por nódulos vermelhos e dolorosos, encontrados principalmente na parte inferior das pernas. Sua causa exata permanece desconhecida, mas parece resultar de uma resposta exagerada a vários fatores desencadeantes. Embora sua origem seja frequentemente incerta, é essencial descartar outras condições subjacentes antes de diagnosticar eritema nodoso primário. Pode indicar a presença de doenças sistêmicas, como infecções, inflamações, câncer ou reações a medicamentos. Os gatilhos mais comuns incluem infecções estreptocócicas, tuberculose, sarcoidose, doença de Behçet, doença inflamatória intestinal, alguns medicamentos e gravidez.
Erythema nodosum is the most common form of panniculitis and is characterized by tender erythematous nodules mainly in the lower limbs on the pretibial area. The exact cause of erythema nodosum is unknown, although it appears to be a hypersensitivity response to a variety of antigenic stimuli. Although the etiology is mostly idiopathic, ruling out an underlying disease is imperative before diagnosing primary erythema nodosum. Erythema nodosum can be the first sign of a systemic disease that is triggered by a large group of processes, such as infections, inflammatory diseases, neoplasia, and/or drugs. The most common identifiable causes are streptococcal infections, primary tuberculosis, sarcoidosis, Behçet disease, inflammatory bowel disease, drugs, and pregnancy.

Panniculitis refere‑se a um conjunto diversificado de condições inflamatórias que afetam o tecido adiposo subcutâneo. Essas condições são incomuns em crianças. Panniculitis pode ser o problema principal em uma doença sistêmica ou representar uma reação secundária a fatores como infecção, lesão ou determinados medicamentos. Independentemente da causa, a maioria dos tipos de panniculitis apresenta sintomas semelhantes, incluindo nódulos vermelhos e dolorosos na pele.
Panniculitides form a heterogenous group of inflammatory diseases that involve the subcutaneous adipose tissue. These disorders are rare in children and have many aetiologies. As in adults, the panniculitis can be the primary process in a systemic disorder or a secondary process that results from infection, trauma or exposure to medication. Some types of panniculitis are seen more commonly or exclusively in children, and several new entities have been described in recent years. Most types of panniculitis have the same clinical presentation (regardless of the aetiology), with tender, erythematous subcutaneous nodules.

Panniculitis, uma inflamação da camada de gordura sob a pele, é uma condição rara que geralmente se apresenta como nódulos ou manchas inchadas. Erythema nodosum (EN) é o tipo mais comum, geralmente desencadeado por vários fatores. Embora cerca de 55 % dos casos não tenham causa clara, os gatilhos mais frequentes incluem infecções, medicamentos, certas doenças como sarcoidose e doença inflamatória intestinal, gravidez e câncer. A EN costuma aparecer em adolescentes e adultos jovens, com predomínio em mulheres. Muitas vezes é precedida por um mal‑estar geral que dura de uma a três semanas, com sintomas como febre e alterações respiratórias superiores. Em seguida surgem nódulos vermelhos, geralmente nas regiões laterais externas dos braços e das pernas, que podem ser dolorosos. A causa exata da EN ainda não é totalmente compreendida, mas acredita‑se que envolva processos imunológicos nos pequenos vasos sanguíneos da camada de gordura, levando à inflamação. Normalmente, a biópsia revela inflamação na camada de gordura sem dano aos vasos sanguíneos. Mesmo sem tratamento específico da causa subjacente, a EN costuma resolver‑se espontaneamente. Portanto, a maioria dos pacientes necessita apenas de cuidados de suporte para os sintomas.
Panniculitis, an inflammation of the fat layer under the skin, is a rare condition usually showing up as swollen nodules or patches. Erythema nodosum (EN) is the most common type, often triggered by various factors. While around 55% of cases have no clear cause, common triggers include infections, medications, certain diseases like sarcoidosis and inflammatory bowel disease, pregnancy, and cancer. EN usually appears in teens and young adults, more often in females. It's often preceded by a general feeling of illness lasting one to three weeks, with symptoms like fever and upper respiratory issues. Then, red nodules appear, usually on the outer sides of arms and legs, causing pain. EN's exact cause isn't fully understood, but it's believed to involve immune complexes in small blood vessels of the fat layer, leading to inflammation. Typically, a biopsy shows inflammation in the fat layer without damage to blood vessels. Even without specific treatment for the underlying cause, EN often resolves on its own. So, most patients need only supportive care for their symptoms.

O eritema nodoso é diagnosticado clinicamente. Quando o diagnóstico não for claro, pode ser realizada biópsia para exame microscópico. Também deve ser feita radiografia de tórax para descartar doenças pulmonares, especialmente sarcoidose e tuberculose.
