Wprowadzenie to do Necrobiosis Lipoidica in Diabetes

Necrobiosis lipoidica (NL) is a rare, chronologic granulomatos skin condition that discompateratele affectuals individuals wih diabetes mellitus. Originally translated by y Oppenheim in 1929 anditig aid later termed necrobiosis lipoidica diabeticorum byy Urbach in 1932, thee condition is specized by well- determinate, waxy, yllowish- brown aquewith a distvolaceous border, mone common located one pretibial region.

Te hallmark of NL is its chronic, progressive courses with spontanous remission reported in fewer than 20% of cases. Ulceration events in 25% too 35% of patients, often triggered by minor trauma and notoriously slow to heel. Squamous cell canceroma arising in chronic ulcerated NL has also been reported d, underscoring thee importance of respondent moning and earilly intervention.

NL typically begins as or sevel small, red or violaceous papules on lower extremities, most common over the shins. These papules slowly extenge ge coalesce into plaques with a criteristic yellowis- brown, atrophic, and waxy center.
