Rare clinical features of the Ellis van Creveld syndrome: A case report and literature review.

Ellis van Creveld syndrome (EVC) is a rare autosomal recessive disorder also called chondroectodermal dysplasia. This study reports on a 40-year-old woman from Iran with a syndromic appearance consisting of a coarse face, conical anterior teeth, dental agenesis and permanent teeth at birth, several small extralabial, nonmidline frenula with a high-arched palate, and a large maxillary labial frenulum. The patient had cyanosis on her lips since childhood and a history of adenoid tonsillectomy surgery. She also had androgenic alopecia, an elongated trunk with excessive lordosis and pectus excavatum, polycystic ovarian syndrome, and a history of two periods in a month. She also had multiple fibrocystic cysts in her breasts, lower extremity deformity, dysplastic genu valgum, and short limb dwarfism; she had undergone left knee surgery four times and had severe osteoporosis in some of her bones and some hyperpigmented patches on the dorsal of the left hand. Her hands and feet were also wide and markedly deformed with hypoplastic fingernails and toenails, and she had bimanual hexadactyly on the ulnar side of the hands. She also had a history of severe hypotension and cyanosis during surgery and suffered from congenital heart failure and had undergone open heart surgery for correcting her atrial heart defect. In this study pectus excavatum, Phrygian cap gallbladder, liver hemangioma, polycystic ovarian disease, and breast fibrocystic cysts was reported for first time in this case of EVC syndrome. This case was reported and all articles regarding common, uncommon, rare, and extremely rare presentations of this syndrome were reviewed.
