Microvenular hemangioma is a rare, benign vascular lesion that typically presents as a slowly growing, solitary, red or purple papule or plaque. It was first described in 1980 by Winkelmann and Muller. The lesion is characterized by a proliferation of small, thin-walled venules in the superficial dermis.
Clinical Presentation[edit]
Microvenular hemangioma usually presents as a solitary, slowly growing, red or purple papule or plaque. The lesion is typically less than 1 cm in diameter, but larger lesions have been reported. The most common location is the extremities, but it can occur anywhere on the body. There is no gender or age predilection.
Histopathology[edit]
Histologically, microvenular hemangioma is characterized by a proliferation of small, thin-walled venules in the superficial dermis. The venules are lined by a single layer of flat endothelial cells. There is usually a sparse perivascular lymphocytic infiltrate. The overlying epidermis and dermis are usually normal.
Diagnosis[edit]
The diagnosis of microvenular hemangioma is based on the clinical presentation and histopathological findings. Other vascular lesions, such as capillary hemangioma and venous lake, should be considered in the differential diagnosis.
Treatment[edit]
Treatment is usually not necessary as microvenular hemangioma is a benign lesion. However, if the lesion is bothersome or cosmetically unacceptable, it can be removed by surgical excision or laser therapy.
