Abstract
피하에 존재하면서 점액성을 나타내는 양성 종양중에서 단발성이고 무증상이면서 얼굴,
체간, 사지등에 소결절로 나타나는 것을 1966년 Johnson과 Helwig등이 cutaneous focal
mucinosis라고 불렀다. 그후 1988년에는 Allen등이 표재성 혈관점액종(superficial
angiomyxoma)이라고 명명하는 것이 좋겠다는 제안과 함께 30예를 모아 보고하였다. 이들에
대한 전자현미경적 소견이 1989년 Nishiura등에 의해 기술되었다. 저자들은 그들이 보고한
소견과 일치하면서 과거에 그 부위에 외상과 감전손상을 입은 기왕력을 가졌던 한증례를 경
험하고 그 희유성에 의거하여 이를 보고한다.
#초록#
Superficial angiomyxoma is a comparatively care dermal and subcutaneous tumor. We
report a case of superficial angiomyxoma of the thumb in view of its rarity and typical
light and electronmicroscopic features.
The patient was a 46-year-old male, who presented with an asymptomatic, slowly
enlarging mass chat developed in the left thumb over the 5 years. He had a history of
trauma and electric burin in the same area 20∼30 years ago. Simple X-ray and
magnetic resonance imaging revealed 35×30 ㎜, mass with destruction of distal
phalangeal bone. On operation. the lesion was moderately well circumscribed and soft
with lobulated nodules that elevated the overflying skin and destroyed the undoγtying
bone. The cut surface of the mass was glistening and slimy The mass was whitish
gray and lobulated. Bony involvement was not present.
Microscopically, the tumor was composed of stellated and spindle shaped stromal cells
which were scattered throughout myxoid ground substance. N either nuclear
hyperchromasia nor pleomorphisam was present. Small to medium sited thin walled
blood vessels were scattered. There was a scanty infiltrate of inflammatory cells. The
S-l00 protein immunostaining was negative in tumor cells. On electron microscopy, the
cytoplasm of the stromal cells contained well developed rough endoplasmic reticulums
and other features that indicated differentiation toward fibroblasts. (Korean J Pathol
