Effective Treatment of Cornu Cutaneum With Pachaieruvai: A Traditional Siddha Medicine

A cutaneous horn, also known as cornu cutaneum, is a rare and usually benign growth that forms on the skin, extending outward from the outermost layer known as the stratum corneum. These growths are most often seen in older adults, particularly men, and are commonly linked to prolonged sun exposure, which can increase the risk of underlying conditions like squamous cell carcinoma (SCC). Other factors, such as infections caused by the human papillomavirus (HPV), have also been associated with their development. Treatment for cutaneous horns typically involves surgical excision, which is effective but may lead to issues such as scarring or infection. Other methods, like cryotherapy, laser therapy, topical treatments, and electrodesiccation with curettage, are also available. However, these approaches come with potential downsides, including pain, blistering, changes in skin pigmentation, and high costs, which can discourage some patients from seeking care. An alternative option is Siddha medicine, a traditional form of healing that offers a more natural, affordable, and well-tolerated approach to treating cutaneous horns. A 51-year-old male presented with a conical projection measuring 1 cm in height, located on the palmar aspect of the proximal interphalangeal joint of his right second finger, which had been present for three years. Based on clinical examination, the lesion was diagnosed as a cutaneous horn. The patient underwent treatment with a Siddha formulation called Pachaieruvai, which was applied externally for five consecutive days. In the end, the treatment proved effective, successfully destroying the growth within just 10 days. No adverse reactions or recurrence were observed during subsequent follow-ups, underscoring the intervention's effectiveness and safety.
