ReferencesIs e Erythema nodosum an seòrsa panniculitis cho cumanta, air a chomharrachadh le nodules dearg goirt, a lorgar sa mhòr‑chuid air na casan as ìsle. Tha an dearbh adhbhar fhathast neo‑aithnichte, ach tha e coltach gu bheil e mar thoradh air freagairt àibheiseach do dhiofar luchd‑brosnachaidh. Ged a tha e gu tric mì‑chinnteach cò às a thig e, tha e riatanach na suidheachaidhean bunaiteach eile a thoirt air falbh mus dèan thu breithneachadh air primary erythema nodosum. Faodaidh e nochdadh mar shìmpilear aig galaran siostamach leithid galaran a’ bhroinn, sarcoidosis, galar Behçet (Behçet's disease), galar nan gàineanan tinnealaich (inflammatory bowel disease), streptococcal infections (streptococcal infections), tuberculosis, agus toradh.
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.

Tha Erythema nodosum (EN) a’ toirt iomradh air seata de shuidheachaidhean inflammatoire a bhuaileas an fàth fon chraiceann, a’ leantainn gu nodulan dearg is cruaidh a tha duilich air an dà shìnear. Faodaidh Erythema nodosum a bhith na phrìomh chùis ann an staid siostamach no mar fhreagairt do ghluasadan leithid galar, leòn, no cungaidhean sònraichte. Ge bith dè an adhbhar, tha a’ mhòr-chuid de sheòrsan Erythema nodosum a’ nochdadh comharraidhean coltach ris, a’ toirt a-steach nodulan cruaidh, dearg fon chraiceann.
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, sèid den ìre geir fon chraiceann, a tha mar as trice a’ nochdadh mar nodules sgòthanach no bodhaig. Is e Erythema nodosum (EN) an seòrsa as cumanta, gu tric air a bhrosnachadh le diofar fhactaran. Ged nach eil adhbhar soilleir aig timcheall air 55 % de chùisean, tha adhbharan cumanta a’ toirt a-steach galar, cungaidhean‑leigheis, galar sònraichte leithid sarcoidosis, tuberculosis, agus galar an trachais bhroilleach (inflammatory bowel disease), torrachas, agus aillse. Bidh EN mar as trice a’ nochdadh ann an deugairean is inbhich òga, nas trice ann am boireannaich. Gu tric bidh faireachdainn coitcheann air tinneas a mhaireas aon no trì seachdainean roimhe, le comharran mar fìon is cùisean analach àrd. An uairsin, nochdaidh nodules dearga, mar as trice air taobhan a-muigh nan gàirdeanan agus na casan, a’ cur pian. Chan eil fìor adhbhar EN air a thuigsinn, ach tha e ’ga chreidsinn a ghabhas a’ toirt a-steach iom‑fhilltean dìon ann an soithichean fala beaga den ìre geir, a’ leantainn gu sèid. Mar as trice, bidh biopsy a’ sealltainn sèid anns an ìre geir gun mhilleadh air soithichean fuil. Fiù ’s às aonais làimhseachadh sònraichte airson an adhbhar bunaiteach, bidh EN gu tric a’ fuasgladh le fhèin. Mar sin, chan fheum a’ mhòrchuid de dh’ euslaintich ach cùram taiceil airson na comharran aca.
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.

Tha erythema nodosum air a dhearbhadh gu clinigeach. Faodar biopsy a ghabhail agus a sgrùdadh gu microscopach ma tha an diagnos neo‑chinnteach. Bu chòir X‑ray ciste a dhèanamh gus cuir às do ghalaran sgamhain, gu sònraichte sarcoidosis agus tuberculosis.
