What lesions are noted while inspecting the abdomen of an obese Caucasian patient with silvery white, linear, jagged marks, about 4 cm long?

Striae distensae result from the dermal collagen rupture following rapid skin stretching or hypercortisolism. In the initial phase, they appear pink or violaceous but eventually evolve into atrophic scars with a silvery appearance. They are common in obesity, pregnancy, and puberty. These marks signify previous mechanical stress on the integumentary system. A. Umbilical hernias: This condition involves the protrusion of omental fat or bowel loops through a weakened umbilical ring. It manifests as a soft, skin-covered mass or bulge at the navel. It is a structural defect rather than a linear, silvery skin lesion or mark. B. Striae: Commonly known as stretch marks, these are linear, jagged markings that occur when elastic fibers in the reticular dermis are overstretched. In Caucasian patients, older striae appear silvery-white. They are frequently observed on the abdomen, breasts, and thighs of individuals who have experienced weight changes. C. Spider nevi: These are vascular lesions consisting of a central red arteriole with radiating capillary "legs." They blanch with pressure and are associated with liver disease or pregnancy. They are small, focal vascular structures and do not present as long, linear, silvery scars. D. Cutaneous angiomas: Also known as cherry angiomas, these are small, smooth, slightly raised bright red dots. They are common vascular lesions that increase in number with age. They are not linear or silvery and do not result from skin stretching or obesity-related dermal stress.
