Verrucous hemangioma (also known as verrucous venous malformation): A vascular anomaly frequently misdiagnosed as a lymphatic malformation.

Verrucous hemangioma or verrucous venous malformation is a superficial venous malformation frequently misdiagnosed as a lymphatic malformation because of its classical hyperkeratotic appearance. Clinical characteristics of VVM were studied in patients with a histologically confirmed VVM, and validated in a prospective study of 18 patients. VVM was made of separated vascular elements with irregular shape, in a linear disposition, with variable thickness and keratosis. Its specific vascular pattern consisting of an erythematous patch with scattered small red to violet dots was easily identified using dermoscopy. In many cases, the typical clinical presentation of verrucous hemangioma is sufficient to establish the diagnosis and a biopsy may not be required.
