Abstract: We present autopsy studies in 4 unrelated fetuses with the lethal multiple pterygium syndrome (LMPS) with special emphasis on the neuromuscular system. The data suggest that LMPS combines the manifestations of a jugular lymphatic obstruction sequence with those of an early severe fetal akinesia sequence. The jugular lymphatic obstruction sequence with resultant edema and cystic hygroma colli causes fetal lethality usually in the second trimester of pregnancy. Generalized amyoplasia appears to be an important mechanism in the pathogenesis of fetal akinesia as part of LMPS and is not associated with dysgenesis or degeneration of the central nervous system (CNS) but is apparently the result of an early fetal muscular "dystrophy." We propose a genetically determined insult affecting the early embryonic development of both lymph vessels and muscles as the basic defect in LMPS. Placental structure, studied in all 4 cases, demonstrated that triploidy-like placental lesions are specific to LMPS. The present findings suggest that LMPS may be a less heterogeneous entity than previously proposed.
