Ny Erythema nodosum no karazana panniculitis mahazatra indrindra, miavaka amin'ny nodules mena maharary, hita indrindra amin'ny tongotra ambany. Mbola tsy fantatra ny tena antony mahatonga azy io, saingy toa vokatry ny valin-kafatra mihoa-pampana amin'ny trigger isan-karazany. Na dia tsy azo antoka aza matetika ny fiaviany, dia ilaina ny manilika ireo fepetra fototra hafa alohan'ny hamantarana ny primary erythema nodosum. Izy io dia afaka manondro ny fiandohan'ny aretina rafitra toy ny areti-mifindra, mamaivay, homamiadana, na fanehoan-kevitra amin'ny fanafody. Ny trigger mahazatra dia misy 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.

Ny Panniculitis dia manondro ireo toe-javatra mamaivay isan-karazany mahakasika ny tavy ao ambanin'ny hoditra. Tsy fahita amin’ny ankizy ireny toe-javatra ireny. Panniculitis dia mety ho olana lehibe amin'ny toe-javatra rafitra na fanehoan-kevitra faharoa amin'ny antony toy ny aretina, ratra, na fanafody sasany. Na inona na inona antony, ny ankamaroan'ny karazana panniculitis dia mampiseho soritr'aretina mitovy amin'izany, anisan'izany ny nodules manaintaina sy mena eo ambanin'ny hoditra.
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 , mamaivay ny sosona tavy eo ambanin'ny hoditra, dia toe-javatra tsy fahita firy miseho matetika toy ny nodules nivonto na patch. Erythema nodosum (EN) no karazana mahazatra indrindra, matetika ateraky ny anton-javatra samihafa. Na dia eo amin'ny 55% amin'ny tranga aza dia tsy misy antony mazava, ny trigger mahazatra dia ny aretina, ny fanafody, ny aretina sasany toy ny sarcoidose sy ny aretin'ny tsinay, ny fitondrana vohoka ary ny homamiadana. Matetika ny EN dia miseho amin'ny zatovo sy tanora, matetika amin'ny vehivavy. Matetika izy io dia ialohavan'ny fahatsapana aretina amin'ny ankapobeny maharitra iray na telo herinandro, miaraka amin'ny soritr'aretina toy ny tazo sy olana amin'ny taovam-pisefoana ambony. Avy eo, misy nodules mena, matetika eo amin'ny ilany ivelany amin'ny sandry sy ny tongotra, ka miteraka fanaintainana. Ny tena antony mahatonga ny EN dia tsy fantatra tsara, fa inoana fa tafiditra ao anatin'ny komples immune ao amin'ny lalan-dra kely amin'ny sosona tavy izy io, izay mitarika ho amin'ny fivontosana. Amin'ny ankapobeny, ny biopsy dia mampiseho mamaivay ao amin'ny sosona tavy tsy misy fahasimbana amin'ny lalan-dra. Na dia tsy misy fitsaboana manokana momba ny antony fototra aza, dia matetika ny EN dia mamaha irery. Noho izany, ny ankamaroan'ny marary dia mila fikarakarana fanohanana fotsiny amin'ny soritr'aretiny.
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.

Ny erythema nodosum dia fantatra amin'ny klinika. Ny biopsy dia azo alaina sy dinihina amin'ny mikroskopika mba hanamarina ny aretina tsy azo antoka. Tokony hatao ny X-ray amin'ny tratra mba hisorohana ny aretin'ny havokavoka, indrindra ny sarcoidose sy ny raboka.
