Parathyroid hemangioma

Area of Science:

• Endocrinology
• Surgical Pathology
• Vascular Neoplasms

Background:

• Hemangiomas are benign capillary neoplasms resulting from developmental anomalies.
• While common in the head and neck, parathyroid hemangiomas are exceptionally rare.
• Only five prior cases of parathyroid hemangiomas have been documented in medical literature.

Purpose of the Study:

• To report an additional case of parathyroid hemangioma.
• To emphasize the clinical and radiographic mimicry of this rare entity.
• To raise awareness among surgeons regarding this differential diagnosis.

Main Methods:

• Case presentation of a 68-year-old male patient.
• Detailed gross pathological description of the parathyroid hemangioma.
• Association with primary hyperparathyroidism was noted.

Main Results:

• A hemangioma was found to almost entirely replace the right upper parathyroid gland.
• The tumor measured 1.3 × 1.3 × 1.2 cm and weighed 700 mg.
• The patient presented with primary hyperparathyroidism.

Conclusions:

• Parathyroid gland enlargement caused by vascular neoplasms can resemble hyperplasia or adenomas.
• Surgeons must consider parathyroid hemangiomas in the differential diagnosis of hyperparathyroidism.
• Awareness of this rare entity is crucial for accurate diagnosis and management.
