Erythema nodosumhttps://en.wikipedia.org/wiki/Erythema_nodosum
Erythema nodosum ni hali ya uchochezi inayoonyeshwa na kuvimba kwa seli za mafuta chini ya ngozi, na kusababisha vinundu vyekundu au uvimbe ambao kwa kawaida huonekana kwenye shin zote mbili.

Erythema nodosum hugunduliwa kliniki. Biopsy inaweza kuchukuliwa na kuchunguzwa kwa hadubini ili kuthibitisha utambuzi usio na uhakika. X-ray ya kifua inapaswa kufanywa ili kuondokana na magonjwa ya mapafu, hasa sarcoidosis na kifua kikuu.

Erythema nodosum ni aina ya kawaida ya panniculitis, inayojulikana na vinundu nyekundu vya maumivu, hasa hupatikana kwenye miguu ya chini. Sababu yake halisi bado haijulikani, lakini inaonekana kutokana na majibu ya kupita kiasi kwa vichochezi mbalimbali. Ingawa asili yake mara nyingi haijulikani, ni muhimu kukataa hali zingine za msingi kabla ya kugundua primary erythema nodosum. Inaweza kuonyesha mwanzo wa magonjwa ya kimfumo kama vile maambukizo, kuvimba, saratani, au athari kwa dawa. Vichochezi vya kawaida ni pamoja na strep infections, tuberculosis, sarcoidosis, Behçet's disease, inflammatory bowel disease, certain medications, pregnancy.
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 inarejelea seti tofauti za hali ya uchochezi inayoathiri tishu za mafuta chini ya ngozi. Hali hizi sio kawaida kwa watoto. Panniculitis inaweza kuwa tatizo kuu katika hali ya kimfumo au athari inayofuatia sababu kama vile maambukizi, jeraha au dawa fulani. Bila kujali sababu, aina nyingi za panniculitis zinaonyesha dalili zinazofanana, ikiwa ni pamoja na vinundu vyenye uchungu, nyekundu chini ya ngozi.
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 , kuvimba kwa tabaka la mafuta chini ya ngozi, ni hali nadra kwa kawaida kuonekana kama vinundu au mabaka yaliyovimba. Erythema nodosum (EN) ndiyo aina inayojulikana zaidi, mara nyingi huchochewa na sababu mbalimbali. Ingawa karibu 55% ya kesi hazina sababu wazi, vichochezi vya kawaida ni pamoja na maambukizo, dawa, magonjwa fulani kama sarcoidosis na ugonjwa wa matumbo ya uchochezi, ujauzito na saratani. EN kawaida huonekana kwa vijana na vijana, mara nyingi zaidi kwa wanawake. Mara nyingi hutanguliwa na hisia ya jumla ya ugonjwa hudumu kwa wiki moja hadi tatu, na dalili kama vile homa na masuala ya juu ya kupumua. Kisha, nodules nyekundu huonekana, kwa kawaida kwenye pande za nje za mikono na miguu, na kusababisha maumivu. Sababu halisi ya EN haielewiki kikamilifu, lakini inaaminika kuhusisha kinga katika mishipa midogo ya safu ya mafuta, na kusababisha kuvimba. Kwa kawaida, biopsy inaonyesha kuvimba kwenye safu ya mafuta bila uharibifu wa mishipa ya damu. Hata bila matibabu maalum kwa sababu ya msingi, EN mara nyingi hutatua yenyewe. Kwa hivyo, wagonjwa wengi wanahitaji huduma ya kuunga mkono tu kwa dalili zao.
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.
