ABSTRACT

Primary immunodeficiency diseases (PIDs) are inherited, genetic disorders. The majority of PIDs are diagnosed in infancy or early childhood, but manifestation in adulthood may also occur. Frequent, recurrent and prolonged infections, which respond poorly to treatment may be heralding signs. PID patients may have increased suspectibility to infections, that mostly affect the sino-pulmonary and intestinal tracts and the skin. PIDs are also frequently associated with autoimmune and inflammatory disorders. Cutaneous manifestations affect 40% to 70% of patients with diagnosed PID. Bacterial and fungal infections of the skin, recurrent pyogen abscesses are common complications. Severe atopy, eczema and erythroderma occurring early in childhood should raise awareness of PID. Cutaneous granulomas, pigment changes and dysplasia of skin, hair, and nails can also be seen frequently in some of these conditions. Here we overview the most frequent dermatological diseases occuring in patients with PID. Orv Hetil. 2018; 159(23) 937-947.
