RESUMO

Mast cells (MCs) can release a variety of biologically active mediators under different circumstances, such as fever or vaccination. Our aim was to evaluate the incidence and severity of MC activation symptoms induced by SARS-CoV-2 virus (COVID-19) infection and vaccination in a cohort of 92 pediatric patients with cutaneous mastocytosis. Our findings support previous evidence on the safety of COVID-19 infection and vaccination in patients with MC disorders.

RESUMO

Acral persistent papular mucinosis (APPM) is a rare subtype of localized lichen myxedematosus. It consists of small papules localized exclusively on the back of the hands, wrists and extensor aspects of distal forearms with no other clinical or laboratory manifestations. The lesions tend to persist and may increase slowly in number. Histologically, hematoxylin-eosin and Alcian blue staining demonstrate mucin accumulation in the upper reticular dermis with separation of collagen fibers as a result of hyaluronic acid deposition. Treatment is rarely necessary due to the absence of symptoms. We present a 27-year-old healthy woman with asymptomatic papules on her upper extremities, which adequately meet clinical and pathological criteria of acral papular mucinosis.
