| Dehydrated hereditary stomatocytosis (DHS) is a rare hemolytic anemia characterized by a decreased red cell osmotic fragility due to a defect in cation permeability, resulting in red cell dehydration and mild to moderate compensated hemolysis. Pseudohyperkalemia (loss of potassium ions from red cells on storage at room temperature) is sometimes observed. |

| Deletion 5q35 refers to the different congenital malformation syndromes resulting from deletions of variable extent of the terminal part of the long arm of chromosome 5 (5q), spanning the region from 5q35.1 to 5q35.3. The most significant anomaly is a recurring deletion in 5q35.2 comprising the NSD1 gene that causes Sotos syndrome that is characterized by cardinal features including excessive growth during childhood, macrocephaly, distinctive facial gestalt and various degrees of learning difficulty. Subtelomeric deletions of the terminal 3.5 Mb region on 5q35.3 are very rare, characterized by prenatal lymphedema with increased nuchal translucency, pronounced muscular hypotonia in infancy, borderline intelligence, postnatal short stature due to growth hormone deficiency, and a variety of minor anomalies such as mildly bell-shaped chest, minor congenital heart defects and a distinct facial gestalt. Larger deletions including bands 5q35.1, 5q35.2 and 5q35.3 cause a more severe phenotype that associates severe developmental delay with microcephaly, and significant cardiac defects (e.g. atrial septal defect with/without atrioventricular conduction defects, Ebstein anomaly, tetralogy of Fallot) linked to haploinsufficiency of NKX2.5 (5q35.1). Various combinations of signs may result from deletions of variable extent depending on the genes comprised in the deleted segment. |

| A rare dendritic cell tumour characterised by a neoplasm composed of spindled to ovoid cells with phenotypic features similar to those of normal indeterminate cells. The tumour cells consistently express S100 protein and CD1a, while langerin, specific B- and T-cell markers, CD30, the histiocytic marker CD163, and the follicular dendritic cell markers CD21, CD23, and CD35 are negative. Birbeck granules are absent on ultrastructural examination. Patients typically present with multiple papules, nodules, or plaques of the skin. Primary lymph node or splenic involvement is less common. Systemic symptoms are usually absent. The clinical course is highly variable. |

A proportion of patients are asymptomatic, the disease being an incidental finding during routine check-ups. Diffuse pulmonary nodules and mosaic attenuation can be detected by CT-scan however only histopathology can confirm the diagnosis detecting a multifocal hyperplasia of pulmonary neuroendocrine cells (carcinoid tumorlets). Ventilatory dysfunction can be obstructive and less often restrictive, mixed or non-specific. Symptoms can progress slowly but sometimes lead to respiratory failure. It is considered as a precursor for pulmonary carcinoid tumor. |
