Which deficiency is associated with corneal vascularization, angular cheilitis, stomatitis, glossitis, anemia, and seborrheic dermatitis?

The presentation of corneal vascularization, angular cheilitis, stomatitis, glossitis, anemia, and seborrheic dermatitis points toward a deficiency in Vitamin B2, also known as riboflavin. This vitamin plays a crucial role in the metabolism of various nutrients and is essential for maintaining healthy skin and mucous membranes.

Corneal vascularization can occur due to insufficient oxygen or nutrients, which is often seen in riboflavin deficiency, leading to impaired epithelial integrity. Angular cheilitis, or the inflammation and cracking at the corners of the mouth, along with stomatitis (inflammation of the mouth), glossitis (inflammation of the tongue), and seborrheic dermatitis, indicates disturbances in skin and mucosal health that have been linked to riboflavin deficiency.

Furthermore, riboflavin is involved in the production of red blood cells, which connects the deficiency to anemia. This multifaceted impact of riboflavin deficiency on the skin, mucous membranes, and hematologic system directly aligns with the symptoms presented.

Overall, Vitamin B2 deficiency is significantly associated with these common clinical manifestations, making it the most appropriate choice given the symptoms described.
