What is the diagnosis for a patient presenting with periorbital edema, hematuria, and hypertension following cellulitis?

The correct diagnosis for a patient exhibiting periorbital edema, hematuria, and hypertension following cellulitis is post streptococcal glomerulonephritis.

This condition often arises as a sequela to infections caused by certain strains of Streptococcus bacteria, particularly after skin or throat infections. The hallmark symptoms of post streptococcal glomerulonephritis include swelling (such as periorbital edema), blood in the urine (hematuria), and elevated blood pressure (hypertension). These manifestations are related to the immune response that ensues after the streptococcal infection, leading to inflammation of the glomeruli in the kidneys.

In this scenario, the temporal relationship between the recent cellulitis and the onset of kidney symptoms supports this diagnosis, as the kidneys can be affected by the immune response to the infection, even if the infection itself was localized. The presence of hematuria and significant edema, combined with hypertension, particularly in a young child or individual who has recently had a streptococcal infection, strongly indicates post streptococcal glomerulonephritis.

Other conditions, such as minimal change disease or chronic glomerulonephritis,
