    Notizen: The biopsy diagnosis of prolapsing rectal mucosa syndrome can be difficult. We present two newly described features —‘diamond-shaped’ crypts and mucosal elastin—which appear to be helpful in histological diagnosis. Of 32 biopsies of prolapsing rectal mucosa syndrome, all showed diamond-shaped crypts or mucosal elastin. and 28 contained both. Control biopsies comprised cases of normal or irritable bowel syndrome (46), irradiation colitis and ischaemic colitis (16), inflammatory bowel disease (26), and adenomas (30). Mucosal elastin and ‘diamond-shaped’ crypts with distinctive scalloped edges, which were never seen in prolapse, were observed in half the cases of irradiation and ischaemic colitis. Diamond-shaped crypts were seen in one case of inflammatory bowel disease. Diamond-shaped crypts and elastin were seen in the base of adenomas large enough to cause localized prolapse, and in four biopsies from patients with irritable bowel syndrome, all of whom had given a history of straining at stool.

    Notizen: Up to 15% of abdominal aortic aneurysms are designated as inflammatory. They are characterized by marked fibrous thickening of the aneurysmal wall, with the fibrosis extending into the adjacent retroperitoneum. Thirty-five abdominal aortic aneurysms were studied, 15 inflammatory and 20 atherosclerotic. Of the inflammatory group, 10 were symptomatic and five asymptomatic. For each resection specimen, 59 microscopic features (variables) were scored semi-quantitatively. Discriminant function analysis showed that endarteritis obliterans, fibrosis around nerves or ganglia at the outer margin of mural fibrosis, and the thickness of the combined fibrotic media and adventitia gave a satisfactory high discrimination between atherosclerotic and inflammatory aneurysms. When these three variables are used together, a histological diagnosis of inflammatory aneurysm can be made with an expected accuracy in excess of 80%.

    Notizen: A retrospective histopathological study was undertaken to determine the prevalence of mucin filled ducts and their associated mucinous proliferation in 962 breast cancers and 335 benign lesions. A total of 38 (3%) cases with mucin filled ducts was identified and 27 (2%) of these showed mucin extravasation into the adjacent stroma, changes characteristic of mucocoele-like lesions. This constitutes the largest series reported to date. Of the mucocoele-like lesions 12 were prototypic screen-detected cases; 11 of which were mammographically detected on account of suspicious microcalcification and eight cases (67%) exhibited mucinous atypical ductal hyperplasia without overt malignancy. A further 12 mucocoele-like lesions were incidental findings in screen-detected (11) and symptomatic (one) cancers, the majority of which were invasive ductal carcinomas of no special type. In six of these cases (50%), mucinous atypical ductal hyperplasia or ductal carcinoma in situ was present. Thirty mucinous carcinomas constituted 3% of all cancers and three cases had associated mucocoele-like lesions. Mucinous atypical ductal hyperplasia or ductal carcinoma in situ was also associated with 11 cases of mucinous carcinoma. In six mucinous carcinomas, amorphous microcalcification with a similar appearance to that of benign mucocoele-like lesions was identified in the mucin, suggesting a possible link between the two lesions. Mucin-filled ducts or mucocoele-like lesions were almost twice as frequent in screen-detected as in symptomatic lesions. The presence of mucinous atypical ductal hyperplasia in screen-detected mucocoele-like lesions, a decade earlier than the peak of mucinous carcinoma, is a possible risk factor for subsequent invasive malignancy. Mucin-filled ducts, mucocoele-like lesions, mucinous atypical ductal hyperplasia or ductal carcinoma in situ and mucinous carcinoma may represent different stages of the same disease process. Our findings suggest that patients with mucin-filled ducts of mucocoele-like lesions merit close follow-up.

    Notizen: We retrospectively reviewed 107 consecutive cases of radial scar and complex sclerosing lesions in a 54 month period seeking vascular lesions using archival H & E stained 5 μm thick sections. Eight showed vascular abnormalities, five being false aneurysms which were limited to 62 lesions 〉10 mm diameter; no false aneurysm was found in 45 radial scars ≤10 mm. All cases displayed arterial lesions, but two also showed associated venous fibrosis. Traumatic false aneurysms with loss or severe thinning of the media and intimal, medial or extravascular spindle cell proliferation were found in the arteries of five cases with histological evidence of local reaction to previous fine-needle aspirational biopsy and clinical documentation of aspiration 18 to 121 days before. The diameters of the false aneurysms correlated with the original widths of the arteries. The other lesions with mature intimal fibrosis in arteries or veins lacked such local post-aspiration expansile reactive changes, or a history of fine needle aspiration. We conclude that traumatic false aneurysms found in complex sclerosing lesions seem to be iatrogenic, resulting from fine needle aspiration. Mature fibrosis in veins or arteries are probably unrelated processes.

    Notizen: To investigate the prevalence of squamous epidermoid inclusion cysts after wide-core needle biopsy.〈section xml:id="abs1-2"〉〈title type="main"〉Methods and results:Epidermoid inclusion cysts were found in five of 17 surgical excisions (29%) after preliminary wide-core needle biopsies in a 7-month period. Thereafter they were not seen in 26 subsequent postwide-core surgical excisions in a period of 6 months.〈section xml:id="abs1-3"〉〈title type="main"〉Conclusions:The cysts appear to be an iatrogenic complication of wide-core biopsy, and need morphological recognition in order to avoid confusion with spontaneous squamous metaplasia of benign or malignant breast epithelium. Longer term implications are unknown.

    Notizen: Summary A solution of silver nitrate in methanol was used to assess the demonstration of the true surgical excision margin at histology of 100 skin excisions for basal cell carcinoma. In 15% of cases the true margin was not presented and deeper sections were required. The findings highlight the need for routine marking of excision specimens of neoplastic skin lesions to prevent incorrect diagnosis of incomplete excision based on a false resection margin.
