Fallopian Tube and Broad Ligament: Neoplasms

Abstract

Tubal neoplasms of this type are all very rare, the least uncommon being the adenomatoid tumour which is usually small (1–2 cm across) and occurs in a subserosal site, compressing the muscularis into the tubal lumen (Figure 21.1): histologically and histogenetically this is identical to its myometrial counterpart (see Chapter 17). Benign epithelial neoplasms are exceptional and it is probable that virtually all reported papillomata or adenomata of the tube have been of either an inflammatory or hyperplastic nature: very occasionally a genuine adenofibroma (Figure 21.2) is, however, encountered. Mature cystic teratoma can occur in the tube, these presumably developing from germ cells which have become arrested during their passage through the lumen.
