Enchondromatosis

Enchondromas are common benign cartilage tumors of bone. They can occur as solitary lesions or as multiple lesions in enchondromatosis. When hemangiomata are associated, the condition is known as Maffucci syndrome (614569). Clinical problems caused by enchondromas include skeletal deformity and the potential for malignant change to osteosarcoma (Schwartz et al., 1987). Classification of the Enchondromatoses In their classification of the enchondromatoses, Spranger et al. (1978) called Ollier disease and Maffucci syndrome types I and II enchondromatosis, respectively; metachondromatosis (156250), type III; spondyloenchondrodysplasia (607944), type IV; enchondromatosis with irregular vertebral lesions, type V; and generalized enchondromatosis, type VI. Halal and Azouz (1991) added 3 tentative categories to the 6 in the classification of Spranger et al. (1978). Pansuriya et al. (2010) suggested a new classification of enchondromatosis (multiple enchondromas). [from OMIM]

Achondrogenesis type 1B

Achondrogenesis type 1B (ACG1B), a form of achondrogenesis (see this term), is a rare lethal skeletal dysplasia characterized by severe micromelia with very short fingers and toes, a flat face, a short neck, thickened soft tissue around the neck, hypoplasia of the thorax, protuberant abdomen, a hydropic fetal appearance and distinctive histological features of the cartilage. [from ORDO]

Achondrogenesis, type IB

Clinical features of achondrogenesis type 1B (ACG1B) include extremely short limbs with short fingers and toes, hypoplasia of the thorax, protuberant abdomen, and hydropic fetal appearance caused by the abundance of soft tissue relative to the short skeleton. The face is flat, the neck is short, and the soft tissue of the neck may be thickened. Death occurs prenatally or shortly after birth. [from GeneReviews]

MedGen UID:

Congenital Abnormality; Disease or Syndrome
6.

Achondrogenesis type 2

Achondrogenesis type II is characterized by severe micromelic dwarfism with small chest and prominent abdomen, incomplete ossification of the vertebral bodies, and disorganization of the costochondral junction. This form is an autosomal dominant trait occurring mostly as new mutations. However, somatic and germline mosaicism have been reported (summary by Comstock et al., 2010). [from OMIM]
