Assessment of elastosis in invasive ductal carcinoma of the breast compared to fibroadenoma among Sudanese patients using conventional histochemical methods.

We aimed to identify, using histochemical methods, the degree of elastosis in a malignant breast tumor compared to a benign tumor. Sixty-four tissue blocks were used in this study of which 34 (53.1%) were Invasive ductal carcinoma (IDC) (cases) and 30 (46.8%) were fibroadenomas (controls). Examination of Verhoeff's stained sections revealed different grades of elastosis in 29 (85.2%) cases compared to seven (23.3%) in controls. These findings indicated that elastosis was a prominent feature of IDC (p < 0.000). IDC was associated with more frequent occurrence of different grades of elastosis and should, therefore, be considered a valuable histological finding. Nevertheless, more advanced technology for quantitative measurements of the staining density is recommended to confirm this variation.
