Scurvy. A forgotten pseudovasculitis

Scurvy is a nutritional disease caused by ascorbic acid (vitamin C) deficiency. Althought currently it is a rare disease, we should considerer it in the differential diagnosis of purpura and arthritis in patients with restrictive diets. We present the case of a 49-year-old man with a history of a nutritional disorder presented to our hospital with generalized purpura and hemarthros. Following the anamnesis and laboratory findings, rheumatological, infectious and hematological etiologies were excluded. Finally, the diagnosis of scurvy was made upon demostration poor levels of vitamin C and a spectacular response to nutritional supplements. We compare this case with 19 similar cases reported in the medical literature.

Scurvy: A Rare Disease or a Rare Diagnosis?

Introduction

Scurvy, the disease state caused by ascorbic acid deficiency, was once an extremely common disease but is now thought to be a rare disease in postmodern societies. Physicians are not trained to consider scurvy as a possible diagnosis in patients at risk; rather, it is considered a rare diagnosis to add to a differential for completeness's sake.

Methods

We sought to describe the scorbutic patients seen by one physician during a busy academic emergency medicine career. Case series of patients seen by one physician between 1993 and 2023 at five academic teaching hospitals with Emergency Departments (EDs) in the mid-Eastern United States. Presenting signs and symptoms, known scurvy risk factors, Vitamin C levels, clinical course, and outcome for each patient are described.

Results

There were 14 presentations by 12 patients diagnosed with scurvy who were initially evaluated in the ED between 1993 and 2023. Each patient had a known risk factor for inadequate Vitamin C intake. All had clinical findings suggestive of scurvy and all but one had a subnormal serum Vitamin C level detected on serum samples sent from the ED.

Conclusion

The detection of 12 cases of scurvy by one physician over a three-decade period highlights the importance of screening for scurvy in at-risk populations and generates the hypothesis that scurvy is not a rare disease but rather a rare diagnosis. This research hypothesis should be investigated in further studies.

A Rare Presentation of Scurvy in a Well-Nourished Patient

Vitamin C deficiency, otherwise known as scurvy, is a rare diagnosis among populations with adequate nutritional resources. We present a 37-year-old female patient with bilateral lower extremity edema, episodic anasarca, petechiae, and easy bruising who was diagnosed with scurvy. Given the clinical presentation, a broad differential was investigated with no findings suggestive of hematologic or cardiovascular pathology. Initial laboratory studies were unremarkable. Progression of cutaneous symptoms and subsequent laboratory findings demonstrating low vitamin C levels supported a diagnosis of scurvy. Classical symptoms of scurvy include mucocutaneous petechiae, poor wound healing, ecchymosis, hyperkeratosis, corkscrew hair, gingival swelling, and bleeding gums. Following standard enteral supplementation of vitamin C, repeat vitamin C levels failed to adequately respond with the patient remaining to be symptomatic. Given a lack of insufficient nutritional intake or known systemic illness, gastrointestinal malabsorptive etiology was suspected. Though rare in the United States, scurvy should be considered in patients with manifestations of a bleeding disorder. A gastrointestinal workup may be indicated if other nutritional deficiencies are identified, or a source of inadequate intake cannot be established.

Suspicion of Munchausen syndrome by proxy with a child's presentation of undernutrition, scurvy, and an apparent Avoidant Restrictive Food Intake Disorder

PURPOSE

Avoidant Restrictive Food Intake Disorder (ARFID) was recently characterized in the DSM-5 classification. Potential differential diagnoses remain poorly reported in the literature. Our purpose was to present a possible Munchausen syndrome by proxy with undernutrition and scurvy, presenting as ARFID in a child.

METHODS

We describe here a case of an 8-year-old boy who presented with severe undernutrition (BMI = 11.4) and scurvy leading to joint pains. The boy had had a very selective diet since early childhood, and his condition required hospitalization and enteral refeeding. Because of his specific eating behaviour, an ARFID was initially suspected. However, observation of the mother-child relationship, analysis of the child's eating behaviour, and retrospective analysis of his personal history suggested that this was not a true ARFID, and that the selective eating behaviour had probably been induced by the mother over many years, who probably maintained a low variety diet.

CONCLUSION

Munchausen syndrome by proxy is a difficult differential diagnosis, which may also affect patients with ARFID symptoms, which may also present in the affected child as apparent ARFID.

Scurvy: A Diagnosis Not to Be Missed

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.

Sailing the ship of life: scurvy and autoimmunity

Celiac disease (CD) is a multisystem disorder known to manifest in a multitude of ways to include diarrhea, anemia, and nutritional deficiencies. The malabsorptive state can present as certain classical conditions such as autoimmune gastritis and osteopenia/osteoporosis but scurvy is less recognized within the literature. In this case, we present a unique presentation of scurvy as a result of an undiagnosed CD.
