Parry–Romberg Syndrome Associated with Hypothyroidism

Parry–Romberg syndrome (PRS) is a rare degenerative disorder of unknown cause, marked by progressive unilateral facial atrophy. It predominantly affects females and commonly involves the left side of the face. We report a rare case of PRS in a 14-year-old male patient involving hemiatrophy of the right side of face involving skin, subcutaneous tissue, muscles of mastication, parotid gland, right hemimandible and maxilla. There was no family history of any syndromic disorder. In our case, the condition was associated with hypothyroidism, highlighting the need for further research to investigate a potential association between PRS and hypothyroidism.
