Pleomorphic Hyalinizing Angiectatic Tumour [Pathology Infographic]

 

Pleomorphic hyalinizing angiectatic tumors (PHATs) are non-metastasizing soft-tissue tumors of uncertain lineage occurring within the superficial subcutaneous tissues and muscles .

Presents in adults between the ages of 10 and 83 years (median age of 51 years), PHATs are more commonly observed in females than in males.

The majority of affected patients present with slowly-growing, painless masses, most commonly involving the lower extremities.

Rarer tumor sites include the arm, chest wall, axilla, popliteal fossa, buttocks, inguinal region, perineum, buccal mucosa and breast.
