Final answer:
Clinical manifestations in both Buerger's disease and Raynaud's phenomenon include sensitivity to cold temperatures, gangrenous ulcers on fingertips, and color changes of fingers and toes.
Step-by-step explanation:
The clinical manifestations seen in both patients with Buerger's disease and Raynaud's phenomenon are sensitivity to cold temperatures (B), gangrenous ulcers on fingertips (C), and color changes of fingers and toes (D). Buerger's disease, also known as thromboangiitis obliterans, is a rare disease of the arteries and veins in the arms and legs. Raynaud's phenomenon is a condition that causes some areas of your body — such as your fingers and toes — to feel numb and cold in response to cold temperatures or stress.
Both conditions can result in reduced blood flow to the extremities, leading to the mentioned symptoms. While intermittent fevers (A) and episodes of superficial vein thrombosis (E) are not commonly shared between these two conditions, they can appear in other vascular diseases.
