Abstract: 
The parathyroid adenoma can be located in an "ectopic" situation in 10% of cases, secondary to "embryonic migration" anomalies. Retroclavicular location of an ectopic parathyroid adenoma is exceptional. Therefore, its diagnosis can be particularly difficult. We report the case of a 51-year-old female patient with no previous history who consulted for asymptomatic hypercalcemia and whose investigations, in particular Technetium Tc 99m Sestamibi scintigraphy, revealed a right retroclavicular parathyroid adenoma measuring 2.7x3.2 cm in an ectopic situation, confirmed on histological examination after surgery.
