Background: Poikiloderma with neutropenia is a rare genetic disorder primarily characterized by the presence of poikiloderma and congenital chronic neutropenia. Mutations in the C16orf57 gene, which encodes the USB1 protein, are implicated as the underlying cause of poikiloderma with neutropenia.
Case Presentation: Our patient, an 11-year-old Syrian male child who presented with poikiloderma, palmoplantar keratoderma, pachyonychia, recurrent infections, and neutropenia, is considered to be the first documented case in Syria.

However, subsequent investigations, including an oral examination, radiographic studies, and blood cultures, ruled out dental infection as the cause of the septic shock.

: In clinical practice, neutropenia is frequently accompanied by other cytopenia; isolated non-chemotherapy-induced severe neutropenia is less frequent and its differential diagnosis can be challenging. In this real-world study with data collected over a 5-year period in a tertiary referral hospital, we primarily sought to identify underlying causes of isolated severe neutropenia (<0.5 × 10/L).
