A 52-year-old male was admitted because of an hourglass transmural lipoma penetrating his left first intercostal muscle, and growing to intra-and extra-thorax areas. Only three hourglass transmural lipomas in adults have been reported in Japan. Combined left collar incision with partial upper median sternotomy provided a good surgical view, and the lipoma was completely resected from intra-and extra-thorax areas. Pathology revealed infiltrating type intramuscular lipoma, which has a tendency for recurrence. Combined left collar incision with partial upper median sternotomy was found to be useful for complete resection of the tumor existing intra-and extra-thoracically in the antero-superior thorax.
