Yellowish papules arranged in a linear fashion were noted over the ankle [Figure - 1] and [Figure - 2]. Grouped skin colored papules were also seen over the thighs, knees and buttocks [Figure - 3]. The general physical examination was normal. [ijdvl.com]
Eruptive skin xanthomas are small, erythematous-yellow nodular papules mostly seen on the buttocks, trunk, and extensor surfaces. This clinical feature is associated with chylomicronemia and occurs due to lipid deposition in the skin. [picmonic.com]
The lesions typically erupt as crops of small, red-yellow papules on an erythematous base, and they may spontaneously resolve over weeks. [namrata.co]
Affected individuals may develop multiple yellowish, lipid-filled bumps (papules) or plaques on the skin (xanthomas). [rarediseases.org]
