Scurvy Skin Manifestations: Key Findings and Clinical Insights
Introduction to Scurvy and Skin Symptoms
Scurvy, a condition caused by a deficiency in vitamin C (ascorbic acid), presents with a variety of symptoms, many of which prominently affect the skin. This article synthesizes findings from multiple research papers to provide a comprehensive overview of the skin manifestations associated with scurvy.
Classic Skin Findings in Scurvy
Perifollicular Hemorrhage and Hyperkeratotic Papules
One of the hallmark skin findings in scurvy is the presence of perifollicular hemorrhage, which is bleeding around hair follicles. This is often accompanied by hyperkeratotic papules, which are small, raised bumps on the skin. These symptoms were observed in a 43-year-old man with a history of alcohol abuse, who presented with perifollicular, hyperkeratotic papules and corkscrew hairs on his forearms, thighs, and upper abdomen . A skin biopsy confirmed perifollicular fibrosis and hemorrhage, consistent with scurvy .
Corkscrew Hairs
Corkscrew hairs, another distinctive feature, are twisted and coiled hairs that result from weakened collagen structures in the hair follicles. This symptom was also noted in the same patient, highlighting its diagnostic significance in scurvy .
Atypical and Uncommon Skin Manifestations
Ecchymoses and Xerosis
In addition to the classic signs, scurvy can present with less common skin manifestations such as ecchymoses (bruising) and xerosis (dry skin). A case study of a 2-year-old girl with scurvy revealed multiple scattered ecchymoses on her extremities and generalized xerosis . These findings underscore the variability in skin symptoms and the importance of considering scurvy in differential diagnoses, especially in patients with restrictive diets.
Gingival Bleeding and Edematous Gums
Gingival bleeding and edematous (swollen) gums are also frequently associated with scurvy. The same 2-year-old patient exhibited violaceous (purple) gums and loosening of teeth, which are indicative of severe vitamin C deficiency . These oral manifestations often accompany skin symptoms and can aid in the diagnosis of scurvy.
Pathobiology and Clinical Implications
Collagen Formation and Skin Integrity
Vitamin C is crucial for collagen synthesis, which is essential for maintaining skin integrity. Deficiency in vitamin C leads to weakened collagen structures, resulting in the skin manifestations observed in scurvy . The pathobiology of scurvy highlights the importance of adequate dietary intake of vitamin C to prevent these debilitating symptoms.
Treatment and Resolution of Skin Symptoms
Treatment with ascorbic acid leads to rapid improvement in skin symptoms. In the case of the 43-year-old man, administration of 500 mg of ascorbic acid daily resulted in the resolution of the rash within one week . Similarly, the 2-year-old girl showed dramatic improvement in her skin condition after just three days of oral ascorbic acid treatment . These cases illustrate the effectiveness of vitamin C supplementation in reversing the skin manifestations of scurvy.
Conclusion
Scurvy, though rare in modern times, can present with a variety of skin symptoms, including perifollicular hemorrhage, hyperkeratotic papules, corkscrew hairs, ecchymoses, and xerosis. Prompt recognition and treatment with vitamin C are crucial for resolving these symptoms and preventing further complications. Understanding the diverse skin manifestations of scurvy can aid in early diagnosis and effective management of this preventable condition.

Scurvy is a nutritional disorder caused by vitamin C deficiency, with atypical clinical and pathological findings in skin, blood, and bone marrow, and can be exacerbated by other comorbidities.
Scurvy: A Disease not to be Forgotten.
Scurvy should be considered in the differential diagnosis of patients with petechiae and ecchymosis, especially when food restriction, malabsorption, or psychiatric disorders are present.
