Abstract
OBJECTIVE
Hajdu-Cheney syndrome (HCS), first described in 1948 by Hajdu and independently in 1965 by Cheney, is an extremely rare disorder characterized by severe and excessive bone resorption leading to osteoporosis, with a wide range of other systemic complications from connective tissue and bone dysplasia. Currently there are approximately 50 distinct cases reported in the literature. There have been several reports associating polycystic kidneys with HCS and several other connective tissue disorders, suggesting a possibility of a hyperproliferative component to the syndrome. No articles exist in the current literature describing a case of HCS with concurrent carcinoma. Here, we present a case of a 54-year-old nonimmune compromised woman with multiple stigmata of HCS and recently diagnosed anal squamous cell carcinoma.
METHOD
This is a case report of HCS and stage T3N0 squamous cell carcinoma of the anus.
RESULTS
This is the first report of a patient with HCS with malignancy.
CONCLUSIONS
We present a patient with HCS who developed anal squamous cell carcinoma. The mechanism of HCS, which is still unknown, may either make patients more susceptible to carcinoma or may just be a reflection of the normal incidence of anal squamous cell carcinoma given attributable risk factors.
