Two Cases of Langerhans' Cell Histiocytosis: Report of Two Cases

ABSTRACT

The authors encountered two cases of Langerhans' cell histiocytosis. One, a three-year-old male, had persistent epiphora and showed exophthalmos of the left eye. A mass was detected in the left orbit and was removed subtotally; pathologic examination revealed Langerhans cell histiocytosis. The other case, a 24-year-old male, presented with a gradually growing palpable mass in the parietal area; the skull defect was punched out in shape. The mass, which was tightly attached to the outer layer of the dura mater, was completely removed. On the basis of pathologic findings, Langerhans' cell histiocytosis was diagnosed, and the patient subsequently underwent radiotherapy.
