Replantation of Pediatric Scalp Avulsions.

Scalp avulsions are rare but can be quite morbid clinical manifestations. Pediatric patients are different from adults as they have not completed their physical, sexual, educational, or psychosocial development. Therefore, the devastation of a failed scalp replantation is much greater on these individuals, their whole future lives, and families.

Necrotizing Fasciitis in Paroxysmal Nocturnal Hemoglobinuria.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, progressive, and life-threatening hematopoietic stem cell disorder characterized by complement-mediated intravascular hemolysis and a prothrombotic state. Patients with PNH might have slightly increased risk of infections due to complement-associated defects subsequent to CD59 deficiency. Here, we report a rare case of a 65-year-old male patient with necrotic ulcers on both legs, where the recognition of pancytopenia and microthrombi led to the diagnosis of PNH based on FLAER (FLuorescent AERolysin) flow cytometric analysis.
