Masson’s tumor of the neck: A rare case report

Masson’s tumor is a rare, benign, vascular lesion, commonly affecting the head, neck and peripheries. It is usually asymptomatic and can be confused with malignant tumors. We report a 56-year-old male who presented with a solitary swelling in the right side of neck which was clinically diagnosed as a benign cystic lesion, hence complete excision of the lesion was done. Histopathology demonstrated the papillary proliferation of endothelial cells, in favour of Masson’s tumor.

Masson’s Tumor-Case Report

Intravascular papillary endothelial hyperplasia or Masson’s tumor is a rare benign vascular pathology. It mainly affects the lower limbs and is not related to the gender or age of the patients. Evaluation by clinical history and imaging exams can be confused with other soft tissue tumors. The purpose of this article is to describe a case attended at a university hospital in Porto Alegre, Brazil. In the present study, the authors report a case of a 54-year-old male patient with the presence of nodulation on the back of the right foot. After inconclusive biopsy, the treatment of choice was surgical resection of the tumor with free margins. Anatomopathological study of the surgical specimen was compatible with Masson’s tumor. A 6-month follow-up did not show any recurrence of the lesion. With this case, the authors wish to highlight this pathology among the differential diagnoses for soft tissue tumors.

A Case of Masson’s Tumor in Lateral Neck

Masson’s tumor, also known as intravascular papillary endothelial hyperplasia (IPEH), is a rare, benign vascular tumor characterized by the proliferation of endothelial cells with papillary formations. Differential diagnosis between IPEH and angiosarcoma is important because both have microscopic similarity. Herein, we report a rare case of IPEH on the right lateral neck of a 50-year-old female presenting with a neck mass, which was completely removed without complication.
