Isolated Lower Limb – a Rare Limb Malformation pregnancy. First born baby died at the age of 10 postnatal day, cause is unknown, but he was apparently not having any congenital Priyanka Bansal*, MD; Akhil Bansal, MD, and malformation. Physical examination revealed Shitalmala Devi, MD weight 4.8 kg, length 54.5 cm, head circumference 36.5 cm, no facial dysmorphism, spine normal. Only deformity was phocomelia of Jawaharlal Nehru Medical College, Department of Pathology, India Jan 29, 2011 Mar 24, 2012 left lower limb (Fig. 1). Systemic examination was normal. X ray pelvis with both lower limbs Received: ; Accepted: showed left lower limb showed absent femur, tibia and fibula, a single tarsal bone visualized, Phocomelia, ie the absence or severe hypoplasia distal foot appears grossly normal. Right and of the long tubular bones with more or less femur do not reveal any abnormality. Chest X ray intact hands and or feet, is widely known to be was absolutely normal and abdominal the most spectacular[1] finding of sonography abdomen and cranianl showed no embryopathy . It may be complete in the form abnormality. 2-dimensional echocardiography that proximal and distal bones of limb are absent was done to rule out congenital heart defect, or may be incomplete when either proximal or which was also[2] normal. distal bones are missing. It is known to occur in Phocomelia in the complete form, the some familial[10] syndromes such as Roberts[8] and forearm are absent in the upper limb and syndrome , the DK Phocomelia syndrome the thigh and leg are absent in the lower limb and in a few other extremely rare syndromes. (the hands and feet sprout directly from the Phocomelia syndromes are multiple malforma- trunk). The deficiency may be proximal ( tions syndrome that includes skeletal, and thighs missing) or distal (forearms and legs genitourinary such as renal agenesis, gastro- missing). This malformation was seen with intestinal system, eye abnormalties eg cloudy thalidomide embryopathy or could be a part of corneas, craniofacial abnormalities including some pseudo–thalidomide syndromes, which silvery blonde hair, extensive[11] hemangiomas and could be familial. Certain syndromes are hypoplastic nasal cartilage . These syndromes reported where phocomelia is one of the include autosomal recessive form of VACTERL- features along with other congenital[3] hydrocephaly syndrome (David-O’Callaghan malformations ie Roberts[4] syndrome , DK syndrome), X-linked recessive form (Hunter Phocomelia syndrome Odontotrichomelic[5] MacMurray) syndrome, DK-phocomelia (von tetramelic ectodermal dysplasia , congenital
