INTRODUCTION: Neurofibromatosis Type 1 (NF1) or Von Recklinghausen’s disease, is a rare genetic disease characterized by multiple benign tumors of nerves and skin (neurofibromas), and skin decorations. However, it is multisystem and can affect each organ in the body, leading to debilitating effects. CLINICAL CASE: We present a case of an 18-year-old girl with NF1. The disease onset started in childhood at the age of 3 years with the appearance of hyperpigmented skin macules. Her mother also presented with multiple nodules on the face and trunk, and her little brother was reported to have disseminated macules. She had poor performance at school and delayed menses. The diagnosis of NF-1 was made, and a multidisciplinary team was involved in management of the patient CONCLUSION: Although genetic testing and confirmation are available, NF1 remains a clinical diagnosis and requires management by multidisciplinary team

| description | INTRODUCTION: Although Treacher-Collins syndrome has to be considered a differential diagnosis
in congenital craniofacial abnormalities, the clinical diagnosis and research related to it still present
a gap, especially in African regions. Thus, this work aims at highlighting this syndrome's clinical
features for raising medical awareness.
CLINICAL CASE: We reviewed a 1-year-old patient referred to our clinical genetic unit at Rwanda
military hospital, Kigali, Rwanda. Physical examinations indicated severe craniofacial abnormalities,
including downward-sloping eyes, slight notching of the lower lids, small and underdeveloped
eyebrow bones, vision problems, small outer ears, small and underdeveloped cheekbones, and
jaw. Within the limits of the techniques used in our laboratory, the cytogenetic analysis revealed
a normal karyotype, 46, XY.
CONCLUSION: The patient was diagnosed with Treacher-Collins syndrome based on clinical
manifestations of craniofacial features. Nevertheless, laboratory tests performed were limited to
karyotyping and should not detect any gene defect. Long-term follow-up of the patient and his
family was recommended. Further molecular analyses should be performed to identify causing
genetic mutation mainly in the TCOF1, POLR1C, or POLR1D genes. |
