Histopathologic findings in a case of recurrent parotitis in adulthood

Most cases with recurrent parotitis in childhood (RPC) can be cured before puberty.^1–3 A few of them, however, may continue to adulthood.^1–4 To distinguish this condition from other types of chronic parotitis in adults, such as chronic obstructive parotitis,⁵ we suggest that the diagnosis of recurrent parotitis in adults (RPA) be reserved for the cases derived from RPC.⁶ The pathophysiology and development of RPA is still not well known. To our knowledge, there are few reports of RPA in the literature, especially concerning its histopathology. This report describes a cases of RPA studied with sialography and light and electron microscopy.
