A 27-year-old woman had congenital lissencephaly syndrome and mental retardation. She had a fever of unknown origin and visited her local physician. Blood test indicated leukocytosis, so she was referred to our hospital for detailed examination. She was diagnosed to have acute myelogeneous leukemia (M5a). The chromosome analysis in blast cells revealed Robertsonian 13;21 translocation. Complete remission was obtained by induction chemotherapy. As normal karyotype (46, XX) was observed in the chromosome analysis of bone marrow cells after remission, it was considered that the patient had acquired Robertsonian 13;21 translocation complicated by acute myelogeneous leukemia.

CINCA syndrome is an autoinflammatory disease in childhood characterized by multisystemic manifestations: cutaneous, articular, and neurological including sensory organs. We report the case of homozygous twins affected by CINCA syndrome. The diagnosis was evoked on the basis of multiple systemic symptoms (multiple episodes of fever of unknown origin, mental retardation, short stature, meningitis, hearing loss, bilateral papilledema) and confirmed by the presence of a CIAS1 mutation on genetic analysis. After few months of treatment by anakinra (an interleukin-1 receptor antagonist) the children began to grow again and we noted regression of the biological inflammatory syndrome.

Congenital insensitivity to pain with anhidrosis is an autosomal recessive disorder caused by mutations in the neurotrophic tyrosine receptor kinase 1 (NTRK1) gene, which encodes the receptor for nerve growth factor. We report the clinical and radiological pitfalls in the diagnosis and treatment of two brothers, aged 5 and 8 years, with congenital insensitivity to pain with anhidrosis, the older brother having a proven NTRK1 mutation. In the neonatal period, both presented with recurrent episodes of fever of unknown origin, but their clinical problems changed later. In addition to severe mental retardation and self-harming behaviour, the older brother developed recurrent nonbacterial destructive infections of both the calcaneus and later the talus. No immunodeficiency was found. The younger brother had three complex fractures with a long history of healing problems: overwhelming production of callus, osteomyelitis and movement restrictions. He has less mental retardation than his older brother and shows no self-mutilation.
