A punch biopsy revealed a sparse, focal, perifollicular, and perivascular lymphocytic inflammatory infiltrate. Extravasated erythrocytes were present in a perifollicular distribution (Figure 2), and there was overlying follicular hyperkeratosis. Deeper tissue sections showed a corkscrew-shaped hair shaft emanating from one follicle (Figure 3). Ascorbic acid levels were undetectable, confirming the diagnosis. Unfortunately, the patient ultimately refused all treatment and was subsequently lost to follow-up.
