Madame Dimanche and Her Horn
In the early 19th century, Parisian widow Madame Dimanche had a wax model created depicting a mysteriously appearing human horn, known as a cornu cutaneum, which had grown on her body for six years before being successfully removed. These horn-like protrusions are composed of keratin, the same protein found in hair and nails, and can vary in size and appearance. Although typically benign, these horns can be a cause for concern as they may signal underlying skin conditions or skin cancer in some cases. Medical attention is crucial for proper diagnosis and treatment.
