Angiomatosis Occurring in an Uncommon Location and Age Group: A Case Report and Literature Review.

ABSTRACT

Angiomatosis is a rare benign vascular malformation. The lesion has a highly infiltrative nature and a high recurrence rate, making it easily misdiagnosed as malignancy. Therefore, diagnosis is best made based on a combination of clinical, radiological, and histological features. This case presentation is unique because aside from the fact that the lesion is rare, it was seen in an uncommon age and location. Occurrence in such location has not been documented, making this presentation the first of its kind. A 29-year-old male presented with a swelling on the right side of the back, reportedly present for the past six years. The swelling was painless, with a history of progressive increase in size. Examination at presentation revealed a fairly round mass located on the back, 5 cm below the right scapula. He underwent a wide local surgical excision with the material sent for histopathological evaluation. Based on the morphologic features, a definitive angiomatosis diagnosis was made. Our patient had complete surgical excision with histologically confirmed free margins and no recurrence after eight months of post-operative follow-up.
