RESUMO
Masson's tumor, also named intravascular papillary endothelial hyperplasia (IPEH), is a rare, benign vascular tumor. Evaluation by clinical features can be confused with other soft tissue tumors. Therefore, the diagnosis should be confirmed by histopathological examination. The patient reported here is 67 years old and came to us with a small painful lesion over the left thumb of about two months duration. Histopathological examination was consistent with Masson's tumor (IPEH) following excisional biopsy, with good functional outcomes. To the best of our knowledge, this is the first report of this entity from Kuwait. Dermatologists and surgeons should know about this rare entity and its unusual presentation, to be able to distinguish it from similar presenting serious conditions, especially angiosarcoma. Through this report, we purport to facilitate recognition of this condition apart from some other conditions it may mimic.
