Winchester syndrome (WNCHRS) presents with severe osteolysis in the hands and feet and generalized osteoporosis and bone thinning, similar to multicentric osteolysis, nodulosis, and arthropathy (MONA; 259600), but subcutaneous nodules are characteristically absent. Various additional features including coarse face, corneal opacities, gum hypertrophy, and EKG changes have been reported (summary by Zankl et al., 2007). Reviews Winter (1989) provided a review of Winchester syndrome. De Vos et al. (2019) reviewed Winchester syndrome, Frank-Ter Haar syndrome (249420), and MONA, tabulating the clinical features of 63 reported patients and noting significant overlap, including craniofacial malformations, reduced bone density, skeletal and cardiac anomalies, and dermal fibrosis. Because the protein products of all 3 causative genes (MMP14; SH3PXD2B, 613293; MMP2, 120360) are involved in collagen remodeling, the authors suggested grouping them together in a revised nosologic classification, designated 'defective collagen-remodeling spectrum (DECORS).'

Multicentric osteolysis nodulosis and arthropathy (MONA) is a skeletal dysplasia characterized by progressive osteolysis (particularly of the carpal and tarsal bones), osteoporosis, subcutaneous nodules on the palms and soles, and progressive arthropathy (joint contractures, pain, swelling, and stiffness). Other manifestations include coarse facies, pigmented skin lesions, cardiac defects, and corneal opacities. Onset is usually between ages six months and six years (range: birth to 11 years).

Multicentric carpotarsal osteolysis syndrome is a rare skeletal disorder, usually presenting in early childhood with a clinical picture mimicking juvenile rheumatoid arthritis. Progressive destruction of the carpal and tarsal bone usually occurs and other bones may also be involved. Chronic renal failure is a frequent component of the syndrome. Mental retardation and minor facial anomalies have been noted in some patients. Autosomal dominant inheritance has been documented in many families (Pai and Macpherson, 1988).
