PURPOSE The role of step section and immunohistochemistry for diagnosing sentinel node micrometastases and the sentinel node concept in patients with prostate cancer was investigated. In patients administered neoadjuvant hormone therapy its influence on the sentinel node concept and metastasis diagnosis was also investigated. MATERIALS AND METHODS Of 62 patients without metastasis enrolled in...

This report describes a case of a well differentiated squamous cell carcinoma (SCC) of the foreskin of a dog, with metastasis in the regional lymph node. A six-year-old male intact Pit Bull dog presented a preputial ulcerated lesion with an evolution time of one year and enlarged left inguinal lymph node. Surgical resection of the preputial lesion and inguinal lymph nodes was made. The diagnosi...

conclusions abnormal e-cadherin expression is a common phenomenon in gastric adenocarcinoma. the study showed a significant correlation between abnormal e-cadherin expression and tumor grade and regional lymph node involvement; so, abnormal e-cadherin expression may be used as a predictive factor for tumor invasiveness in gastric adenocarcinoma. materials and methods a historical cohort survey ...

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon skin disease that presents as papules or nodules in the head and neck region. The pathogenesis of vascular proliferation characterizes ALHE unclear, neoplastic reactive etiologies have both been proposed. Several human polymaviruses (HPyV), including HPyV6, HPyV7, trichodysplasia spinulosa polyomavirus (TSPyV), Merkel Cell (MCPyV...

  Schwannomas are benign nerve sheath tumors that originate from any anatomical site. Most of the schwannomas are found in the head, neck or limbs. Schwannoma arising in a lymph node is extremely rare. We have found only four cases in the review of the literature. We experienced a case of intranodal schwannoma in a perigastric lymph node. A 72 year-old female underwent cholecystectomy due to ...

background : invasive ductal carcinoma is one of the most common type of tumors in females, constituting a single large group of breast cancers. there are various prognostic factors, of which tumor grade, size and axillary lymph node metastasis are among the important ones. fine needle aspiration cytology is a commonly used diagnostic technique in the initial evaluation of breast lumps. in the ...

Squamous cell differentiation (SCD) may occur in papillary thyroid carcinoma (PTC) only at metastatic sites. We have studied cytokeratin CK5/6 and P63 along with TTF1 (thyroid transcription factor 1)  and B-Raf (V-Raf murine sarcoma viral oncogene homolog B1) immunohistochemical expression in neck lymph node metastases of thyroid PTC showing SCD. The patient (21-years) presented wit...

Serial sectioning of breast cancer sentinel nodes does not significantly improve false negativity rate. Manuscript. on behalf of the Swedish Breast Cancer Group and the Swedish Society of Breast Surgeons. Axillary recurrence rate 5 years after negative sentinel node biopsy for...

Immune system plays crucial role in body and lymph nodes are essential parts of this system for combating pathogens. However, no study has ever been conducted on morphometric development of sheep lymph nodes in fetal period. Thus, this study attempted to examine the morphometric characteristics of a number of important lymph nodes of some lymphocenters of sheep during fetal period. To this end,...
