Abstract Undifferentiated connective tissue diseases (STDs) are less common entities characterized by signs and symptoms suggestive of a systemic autoimmune disease, which do not fulfill the diagnostic criteria for a defined connective tissue disease. It is difficult to determine the prevalence of UCTD, but 10% to 20% of referrals to tertiary care clinics may be for this diagnosis. We are reporting a case without any internal organ involvement. Keywords: Connective tissue-related, undifferentiated disease, no systemic organ involvement.
