Intravascular papillary endothelial hyperplasia (IPEH) also known as Masson's hemangioma is a rare benign reactive vascular lesion of the skin and subcutaneous tissue. It is usually confined to the lumen of preexisting vessels/vascular malformations. It is characterized histologically by papillary fronds lined by proliferating endothelial cells. This lesion is often misinterpreted as soft-tissue tumors and other benign and malignant lesions. We present a case of 13-year-old female with IPEH of scalp causing bony defect because of its rarity and diagnostic challenge, it posed due to nonspecific clinical and radiological findings.
A 64-year old male presented in ophthalmology OPD for follow up for refractive errors. He had been wearing bifocal lenses from last 1 year. On local examination, medial canthus of left eye showed a pale yellowish plaque. The rest of the ocular examination and contralateral eye were normal. Slit lamp examination showed a confluent fusiform papule (Figure 1A,B).
