Introduction: The association between neurofibromatosis type 1 (NF-1) and vasculopathy has been reported frequently, especially cerebral, intestinal, and peripheral vasculopathy. However, cutaneous vasculopathy is infrequent.
Case Report: The authors present the case of a 32-year-old man with a painful ulcer on his left thigh of 3 weeks' duration in the same location as a long-time capillary malformation associated with alopecia. The skin biopsy showed signs of perivascular fibromuscular dysplasia with proliferating myofibroblastic cells. The patient had been treated with various therapeutic options, such as topical antibiotics, oral and intralesional corticosteroids, and oral cyclosporine and intravenous prostanoids.
Conclusions: Cutaneous vasculopathy related to the skin, such as livedo reticularis and ulcers of torpid evolution due to cutaneous vasculopathy are extremely rare. Thus, it is necessary to include skin ulcers as one of the phenotypic manifestations of NF-1.

Electrolyte imbalance management is crucial in diverse clinical scenarios, with intravenous potassium repletion often required. High-concentration infusions can pose severe complications if extravasation occurs, leading to phlebitis, local tissue damage, or in severe cases, cutaneous necrosis. This risk is elevated in geriatric patients due to factors like reduced tissue elasticity and sensitivity.

Granulomatosis with polyangiitis (GPA) is a small-to-medium vessel vasculitis that can affect the skin, respiratory tract, kidneys and other organs. A rare cutaneous manifestation of GPA is pyoderma gangrenosum (PG)-like ulcerations, which can have debilitating and disfiguring consequences. We report the case of a man in his 40s with refractory PG-like ulcerations secondary to GPA, not responsive to conventional immunosuppression, who was successfully treated with rituximab.
