Congenital malformation

Microscopic description

A. The sections shows edematous, well-vascularized stromal tissue (consisting of epitheliod cells with lightly eosinophilic cytoplasm) with abundant lymphocytes and plasma cells, focal multi-nucleated giant cells and abundant neutrophils. There are scant fragment of benign endometrial-type epithelium.
B. The sections show non-keratinized squamous (exocervical-type) epithelium with normal maturation to the surface. There is also benign columnar (endocervical-type) epithelium. The supporting stromal tissue shows no pathologic changes. There is no significant inflammation, no metaplasia, and no dysplastic change.

Final diagnosis

A. Soft tissue, right vagina, excision - granulation tissue and benign smooth muscle.
B. Soft tissue, vaginal ("septum (obstructed hemivagina)"), excision - benign cervical mucosa.
