Toe Absence Related to Verrucous Carcinoma
Introduction::Verrucous carcinoma is a rare variant of squamous cell carcinoma. It generally grows exogenously and bone erosion is rare. Here we present a case of verrucous carcinoma on the foot with toe absence.Case presentation::A 64-year-old man presented with a 6-year history of a slowly growing exogenous hyperkeratotic verrucous lesion on the right fifth toe, which had been absent for 1 year. Before the lesion appeared, he had undergone nail extraction on this toe. The culture of fungi and mycobacteria were negative. Three-dimensional computed tomography showed that the fifth toe of the right foot was absent. Histopathological examination showed that the lesion was exogenous and verrucous and exhibited moderate keratinocyte hyperplasia. Combined with clinical manifestation and histopathological examination, verrucous carcinoma is suggested. The lesion was surgically excised, and the patient was followed up for more than 6 months without recurrence.Discussion::Verrucous carcinoma is an exophytic tumor with verrucous growth at the beginning, which can invade deep tissues and even cause limb mutilation. When encountering a patient with a wart-like plaque on the foot that responds poorly to conventional treatments, clinicians should maintain a high degree of clinical vigilance and a low threshold for biopsy.Conclusion::We observed a rare outcome of toe absence associated with verrucous carcinoma. Therefore, early diagnosis of verrucous carcinoma is very important. Surgical excision is an effective treatment at present. Extensive resection is usually required to avoid recurrence.
