Ed. Rosenstein et al., LANGERHANS CELL HISTIOCYTOSIS ASSOCIATED WITH ELEVATION OF ANGIOTENSIN-CONVERTING ENZYME LEVELS - CASE-REPORT, The American journal of the medical sciences, 310(2), 1995, pp. 65-67
The authors describe a 22-year-old man with osteolytic mandibular and
maxillary lesions, Biopsy substantiated the presence of Langerhans cel
l histiocytosis (eosinophilic granuloma). Levels of serum angiotensin-
converting enzyme (ACE) were elevated repeatedly. After definitive the
rapy with excision and bone grafting, ACE levels returned to normal. T
he role of histiocytes in ACE production is discussed. Langerhans cell
histiocytosis should be considered in the diagnosis of conditions occ
urring with elevation of serum ACE levels and clinical findings simila
r to sarcoidosis.
