A new case of reticular hyperplasia connected with volatile oils

摘要: An additional case of "reticular hyperplasia" is described. The clinical picture trimorphic with grouped nodules, spinulosismus-like and parapsoriasiform lesions. Histologically there are dense lymphoreticular, partly eosinophilic infiltrates leucocytoclastic cell aggregates, which, however, do not resemble mycosis fungoides nor a reticulosis. causative agent was most likely the external use remedy for an amputation stump containing ethereal oils, which had been used over decades. Positive provocation tests confirmed diagnosis.
