Evaluation of lumpectomy surgical specimen radiographs in subclinical, in situ and invasive breast cancer, and factors predicting positive margins.

Purpose: To determine the diagnostic performance of radiological evaluation of the margins of surgical specimens from lumpectomies for subclinical malignant breast lesions.

Materials And Methods: Retrospective study in two French hospitals including all patients who had a non-palpable in situ (ISDC) or invasive (IDC) ductal carcinoma treated by lumpectomy after radiological localisation. For the analysis, the lesions were divided into two groups depending on the majority component in the definitive histological examination: ISDC or IDC.

[Cytological diagnostic challenge: two hyalinizing trabecular tumor case reports].

Hyalinizing trabecular tumors (HTT) are very rare thyroid tumors whose diagnosis is difficult, particularly in cytology. They are frequently diagnosed as papillary carcinomas due to the cytological similarities between those two tumors (anisocariosis, intranuclear cytoplasmic inclusions, nuclear grooves and nuclear overlapping). Here, we report two HTT cases which were initially diagnosed as papillary carcinoma, on the preoperative cytology and for which the patients underwent total thyroidectomy with lymph node dissection.

[Specimen radiography assessment of surgical margins status in subclinical breast carcinoma: a diagnostic study].

Objective: This study aimed to determine the accuracy of specimen radiography in evaluating the surgical margins of impalpable breast carcinoma.

Design And Setting: Retrospective study from June 2009 to June 2010 in Orleans Hospital Center.

Patients And Methods: The study involved patients with impalpable in situ breast carcinoma diagnosed by mammography.

Preoperative US-guided hook-needle insertion in recurrent lymph nodes of papillary thyroid cancer: a help for the surgeon.

Objective: The objective of this study is to investigate whether preoperative ultrasound guided insertion of a hook-needle is useful in reoperations for cervical recurrent lymph node metastases of papillary thyroid cancer.

Patients And Methods: 8 patients with operated papillary thyroid cancer were included in this study. They all had suspicious nonpalpable cervical lymph nodes discovered during follow-up.

Mastectomies after vacuum core biopsy procedure for microcalcification clusters: value of clip.

Purpose: The study was performed to substantiate the value of detecting clips in mastectomy specimens as a guide to taking pathological samples.

Material And Methods: We performed a retrospective review of 4 cases of mastectomy required after biopsies of microcalcifications. In each case a metallic clip had been inserted at the end of the vacuum core biopsy procedure.
