RESUMO
Vitamin C deficiency, one of the oldest-known nutritional disorders, is now uncommon in high-income countries. Recently, however, there has been an increase in cases of vitamin C deficiency, also known as scurvy. We report three adult patients with histories of homelessness, food insecurity, and poor nutrition, making them particularly vulnerable to restrictive diets and at increased risk for scurvy. After proper diagnosis and treatment, favorable outcomes can be rapidly obtained. This case series emphasizes the importance of keeping a broad differential diagnosis and inquiring about nutritional history in patients presenting with purpura, gingival bleeding, and body hair changes.
RESUMO
Sweet syndrome (SS), or acute febrile neutrophilic dermatosis, is a rare painful skin condition that is characterized by hyperpyrexia, peripheral blood and skin neutrophilia, and edematous skin lesions. Necrotizing SS (NSS) is a severe and locally aggressive condition that histopathologically resembles a necrotizing soft tissue infection. As opposed to necrotizing soft tissue infections, NSS responds to systemic steroids. SS is divided into three subtypes: classical SS, malignancy-associated SS, and drug-induced SS. Within the malignancy-associated SS subtype, both solid tumor and hematologic malignancies have been precursors to developing SS. Here, we present a case of acute myeloid leukemia-associated NSS.
