Solitary fibrous tumour of round ligament mimicking a leiomyoma.

摘要

Dear Sir,Here we describe a 41-year-old female who was referred in 2004 with a fibroid uterus initially noted during pregnancy. On examination she had an 18-week sized uterus, which subsequent radiological investigation confirmed as two uterine leiomyomas. The masses continued to enlarge and were unresponsive to hormonal therapy. Embolisation was unsuitable, and so a hysterectomy was performed, which revealed a single large mass arising from the left round ligament.Macroscopically, received separately from the main hysterectomy specimen, was a firm, well-circumscribed mass measuring 80 x 60 x 40 mm, with a uniform, white/yellow, whorled cut surface, typical of a leiomyoma, labelled mass from round ligament. The uterus was otherwise unremarkable.Histologically, the tumour was composed of haphazardly arranged round to spindle-shaped cells with vesicular nuclei and little cytoplasm, forming a well-circumscribed, encapsulated mass. There were alternating hypercellular and hypocellular areas, with intervening small, branching vascular channels (Figure 1).
