Masson Tumor as a Neck mass

 

Introduction:

Masson tumor is a benign intravascular tumor, which is seen typically in the fingers. Histologically featured by endothelial papillary projection limited in the intravascular space associated with thrombi, with no pilling up of of the endothelial, Atypia or necrosis aren't usual. CD 31 and CD 34 stains were the most efficient markers to identify the vascular origin. The pathogenesis is still unknown. Surgical excision is the method of treatment.

Method:

a Case report of Masson tumor as lateral neck mass.

Results:

A 55 year old man presented with a right lateral neck mass for 3 weeks. CT scan of the neck showed an oval, well circumscribed cystic mass and measured by 20 mm × 9 mm over the right Sternocleidomastoid muscle with peripheral vessel draining into the right anterior Jugular Vein. The mass was surgically excised and pathologically reported with a thrombosed material in the intralumen of a small vein with differentiated papillary structure and there was no nuclear atypia or necrosis. The patient recovered without complications and he was followed up for 8 months without any evidence of recurrence.

Conclusion:

Masson tumor is an extremely rare presentation of masson tumor. The diagnosis of IPEH important and challenging, because it could mimic angiosarcoma.
