Fibromatosis-like carcinoma-an unusual phenotype of a metaplastic breast tumor associated with a micropapilloma

BACKGROUND: Fibromatosis-like metaplastic carcinoma is a newly described metaplastic breast tumor, literature on which is still evolving. CASE PRESENTATION: A 77-year-old lady presented with a 2 × 2 cm mass with irregular margins in the upper and outer quadrant of left breast. Fine needle aspiration cytology (FNAC) from the lump was inconclusive. A lumpectomy was performed and sent for frozen section, which revealed presence of spindle cells showing mild atypia in a sclerotic stroma. The tumor cells revealed prominent infiltration into the adjacent fat. A differential diagnosis of a low-grade sarcoma vs. a metaplastic carcinoma, favoring the former, was offered. Final histology sections revealed an infiltrating tumor with predominant spindle cells in a collagenous background, simulating a fibromatosis. Adjacent to the tumor were foci of benign ductal hyperplasia and a micropapilloma. Immunohistochemistry (IHC) showed diffuse co-expression of epithelial markers i.e. cytokeratins (CK, HMWCK, CK7) and EMA along with a mesenchymal marker i.e. vimentin in the tumor cells. Myoepithelial markers (SMA and p63) showed focal positivity. A diagnosis of a low-grade fibromatosis-like carcinoma breast associated with a micropapilloma was formed. CONCLUSION: Fibromatosis-like carcinoma is a rare form of a metaplastic breast tumor. This diagnosis requires an index of suspicion while dealing with spindle cell breast tumors. The importance of making this diagnosis to facilitate an intra operative surgical planning is marred by diagnostic difficulties. In such cases, IHC is imperative in forming an objective diagnosis

Effectiveness of a national quality improvement programme to improve survival after emergency abdominal surgery (EPOCH): a stepped-wedge cluster-randomised trial

Background: Emergency abdominal surgery is associated with poor patient outcomes. We studied the effectiveness of a national quality improvement (QI) programme to implement a care pathway to improve survival for these patients. Methods: We did a stepped-wedge cluster-randomised trial of patients aged 40 years or older undergoing emergency open major abdominal surgery. Eligible UK National Health Service (NHS) hospitals (those that had an emergency general surgical service, a substantial volume of emergency abdominal surgery cases, and contributed data to the National Emergency Laparotomy Audit) were organised into 15 geographical clusters and commenced the QI programme in a random order, based on a computer-generated random sequence, over an 85-week period with one geographical cluster commencing the intervention every 5 weeks from the second to the 16th time period. Patients were masked to the study group, but it was not possible to mask hospital staff or investigators. The primary outcome measure was mortality within 90 days of surgery. Analyses were done on an intention-to-treat basis. This study is registered with the ISRCTN registry, number ISRCTN80682973. Findings: Treatment took place between March 3, 2014, and Oct 19, 2015. 22 754 patients were assessed for elegibility. Of 15 873 eligible patients from 93 NHS hospitals, primary outcome data were analysed for 8482 patients in the usual care group and 7374 in the QI group. Eight patients in the usual care group and nine patients in the QI group were not included in the analysis because of missing primary outcome data. The primary outcome of 90-day mortality occurred in 1210 (16%) patients in the QI group compared with 1393 (16%) patients in the usual care group (HR 1·11, 0·96–1·28). Interpretation: No survival benefit was observed from this QI programme to implement a care pathway for patients undergoing emergency abdominal surgery. Future QI programmes should ensure that teams have both the time and resources needed to improve patient care.

Primary cutaneous marginal zone lymphoma (immunocytoma like) with lymphoepithelioid or Lennert′s lymphoma like involvement of nodes

Primary cutaneous marginal zone lymphomas (PCMZL) have a wide range of morphology from tumors with monocytoid B cells to those composed entirely of plasma cells and the T-cell rich variants. We report a 60-year-old male with a PCMZL rich in plasma cells of the foot with a lymphoepithelioid-like pattern of dissemination to the lymph nodes posing problems in the diagnosis. The patient had a lesion on the dorsum of the foot which histologically revealed dense perivascular collections of lymphoid cells and plasma cells amidst fibrous tissue. Though the plasma cells did show light chain restriction, CD20 and CD3 did not reveal an overwhelming B/T-cell population and hence a diagnosis of a reactive process was offered. Subsequently the patient developed inguinal nodes with diffuse loss of architecture and replacement by epithelioid histiocytes and reactive T cells with few large B cells (lymphoepithelioid-like pattern). On pathology review it was realized that the two lesions may be related and clonality studies were asked for. The skin lesion showed clonally rearranged IgH receptor while the T-cell receptor rearrangement was negative. The patient developed disseminated disease and received six cycles of chemotherapy with partial response and 6 years after the initial presentation was alive with nonprogressive disease. Thus, the polymorphous background in PCMZL is evolving and an immunocytoma-like tumor can show a T-cell rich or Lennert′s like growth pattern of spread and early recognition these odd patterns may aid in appropriate management of patients
