The immunohistochemical (IHC) staining of the human epidermal growth factor receptor 2 (HER2) biomarker is widely practiced in breast tissue analysis, preclinical studies, and diagnostic decisions, guiding cancer treatment investigation pathogenesis. HER2 demands laborious chemical processing performed by a histotechnologist, which typically takes one day to prepare laboratory, increasing analy...

Background : Lung cancer is the leading cause of cancer-related mortality over worldwide. Although pathological diagnosis lung carcinoma limited as only small specimen available for diagnosis, availability targeted therapies has created a need precise subtyping non-small cell carcinoma. Several recent studies have demonstrated that use immunohistochemical markers can be helpful in differentiati...

BackgroundSolid pseudopapillary neoplasms (SPNs) are uncommon tumors of low malignancy with a generally favorable prognosis, mostly originating from the pancreas. To date, 12 cases SPNs primary ovarian origin (SPN–Os) have been reported globally, and their detailed characteristics not fully elucidated.Case descriptionWe 13th SPN-O case, which occurred in 52-year-old woman an 18.5 cm left mass. ...

Objectives Graft-versus-host disease (GVHD) is an important complication of bone marrow transplantation. Recent reports suggest the significance T-cell subsets (Th1, Th17, and cytotoxic CD8+ T cells) as well CD163+ macrophages in development cutaneous GVHD. produce various chemokines to establish immunological microenvironment following stimulation by stromal factors lesional skin. Thus, purpos...

BACKGROUND Mutations in the p53 tumor suppressor gene (also known as TP53) have been detected in a wide variety of human cancers. In breast cancer, the presence of p53 gene alterations has been associated with worse prognosis. PURPOSE We compared a complementary DNA (cDNA)-based sequencing method and an immunohistochemical (IHC) method for their abilities to detect p53 mutations in breast can...

Abstract Introduction/Objective T-cell-associated antigens (TCA) are rarely expressed by Hodgkin/Reed-Sternberg (HRS) cells of classical Hodgkin lymphoma (cHL) and is associated with uncertain clinical significance. Methods/Case Report We present a very recent case 68 year-old female no significant past medical history presented large right groin mass for 1 month. She denied any fever, night sw...

subcutaneous panniculitis-like t-cell lymphoma (sptcl) is an infrequent cytotoxic t-cell lymphoma of the skin with a unique immunophenotypic profile. here we describe this lymphoma in a 30-year-old iranian woman. she presented with periorbital edema, mandibular swelling with edematous areas on her face and two small lymph nodes (6-7mm) in the cervical area. histopathological findings revealed l...

BACKGROUND Histopathological diagnosis is important for prognostication and choice of treatment in patients with cancer in the lung. Metastases to the lungs are common and need to be distinguished from primary lung cancer. Furthermore, cases with synchronous or metachronous primary lung cancers (although infrequent) are often handled differently than cases with lung cancer with intrapulmonary m...

Primary meningeal sarcoma is a rare tumor in pediatric age group. Here we were reporting an extremly rare case report of an 11 year old boy presented with quadriparesis and bladder involvement. MRI revealed a cervical dural based tumor with extension to cord parenchyma and neural foramina involving paravertebral tissue. The histopathology revealed mesenchymal tumor with malignant potential whic...

Any diagnostic method for detection of occult metastases in sentinel lymph node (SLN) could change postoperative therapeutic management. In this study, we attempted to evaluate the usefulness of immunohistochemical (IHC) studies for histopathological SLN examination and their impact on the diagnosis of metastatic lesions. Analyzed data concerned 1358 breast cancer patients referred for sentinel...
