ABSTRACT
A 91-year-old man presented with pruriginous tense blisters and erosions on the upper and lower extremities (Figures 1A and 1B). Mucous membranes were unaffected and Nikolsky's sign was negative. These lesions appeared 48 hours after the administration of the second dose of the Pfizer-BioNTech COVID-19 vaccine. The patient had received the first dose of the same vaccine 23 days prior to the onset of lesions. He did not suffer from any other post-vaccination adverse effects.

Alopecia neoplastica is a rare type of cutaneous metastasis. The most frequent presentation consists of red-violaceous nodular scarring alopecia located at the parietal area. The most frequent primary tumor locations are the breast and gastrointestinal tract. We report a case of alopecia neoplastica that induced an underlying lytic bone metastasis. After a rigorous literature search, we could not find another case showing this mechanism.
