Abstract
The current study presents the first case of a lipomatous hemangiopericytoma (LHPC) developing in the parotid gland in a 33‑year‑old male. The patient presented with a 4-year history of a progressively growing painless and fixed mass in the left paratid gland region. The patient underwent radical parotidectomy and was followed-up for 12 months without any evidence of metastasis or recurrence. LHPC, a controversial rare HPC variant, is histologically characterized by a varying admixture of hemangiopericytomatous vasculature and the presence of mature adipocytes. To date, 51 cases of LHPC have been documented in the literature. Although the boundary between HPC and solitary fibrous tumors (SFTs) has become increasingly blurred, neither of these variant growth patterns has previously been recognized in the parotid gland.
