Precise diagnosis is important due to nonspecific findings on imaging tests, its aggressive behaviour and poor response to radiotherapy. The essential point in the diagnosis of MACP is to rule out the extraprostatic malignancies, originating from the bladder or colorectum. Case Report: A 57-year-old man presented in our clinic with urinary frequency, nocturia and voiding difficulties. Digital rectal examination revealed a slightly enlarged prostate, without palpable nodules. Patient PSA was 18.0 ng/mL. Twelve-core transrectal ultrasound-guided biopsy confirmed prostate cancer with Gleason score 8 (3+4). Up to 50% of the tumor lesion consisted of neoplastic glands with isolated cells, floating in mucinous material. The metastatic work-up, including CT scan and bone scintigraphy was negative and radical retropubic prostatectomy with lymph node dissection has been performed. Periodic Acid Schiff staining confirmed the presence of mucinous prostatic adenocarcinoma. Morphological examination was negative for lymph nodes metastases. The extraprostatic extension and surgical margins were negative. Three years after surgery, patient’s serum PSA remained undetectable, without recurrence. Conclusion:  We report this case due to the rarity of primary MACP and its challenging diagnosis. Although MACP may be associated with poor outcome, its proper diagnosis and treatment significantly contribute to favorable prognosis and patient survival.","PeriodicalId":92215,"journal":{"name":"International clinical pathology journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43458788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequent somatic mutations may assist the propagation of the virus. Pathogenic determinants of malignant conversion such as smoking, concomitant infections, dietary deficiencies, hormonal changes may expedite the cellular adaptations. The specific HPV-DNA may be amply evidenced in the neoplasm.2,3 The p53 protein assists the determination of the DNA repair or the activation of programmed cell death (apoptosis),7 a characteristic of the negatively coordinated cell growth. Initiation of p53 protein may competently inhibit cell growth and signify cell death (apoptosis). Protein E6 of the transforming HPV (16/18) may efficaciously combine with protein p53. The viral protein E6 engages the cellular protein E6 AP which is employed as a Ubiquitin ligase for the p53 comprising complex. Ubiquitination of the p53 emerges due to the protein retention, followed by marked degradation. In the absence of p53 protein, the cell is deprived of the ability to discern and restore the latent, devastated DNA.

Breast cancer like many other types of cancer is a complex heterogeneous disease controlled by a multitude of genetic and epigenetic alterations.1. In Pakistani females, breast carcinoma occurs at a younger age group. Infiltrating ductal carcinoma is the most common type of tumour.2 Male breast carcinoma is an uncommon disease.3 Less than 1% of all breast carcinomas occur in men.4,5 The pathology is similar to that of female breast cancer, and infiltrating ductal cancer is the most common tumor type.6 During the past two decades the mortality rate has declined significantly, primarily due to the early use of adjuvant chemotherapy as well as detection of earlier stage tumours due to increased screening.7,8 Prognosis and management of breast cancer is influenced by the classical variables such as histological type and grade, tumour size, lymph node status, and status of hormonal receptors, Estrogen receptors (ER) and progesterone receptors (PR) of the tumour and more recently Her2Neu oncoprotein status.8,9 ER expression is undoubtedly the most important biomarker in breast cancer, because it provides the index for sensitivity to endocrine treatment. ER positive tumours (80% of breast cancer) use the steroid hormone estradiol as their main growth stimulus; ER is therefore direct target of endocrine therapies. PR expression is strongly dependent on the presence of ER. Tumours expressing PR but not ER are uncommon and represent <1 % of all breast cancer.10 The proto–oncogene(C–erb) has been localized to chromosome 17q and encodes a transmembrane tyrosine kinase growth factor receptor. The name for the Her2 Neu is derived from human epidermal growth factor receptor, as it features substantial homology with the epidermal growth factor receptor (EGFR).11,12 Amplification and/or overexpression of Her2/ Neu gene is routinely evaluated using immunohistochemistry and or/ fluorescence insitu hybridization (FISH) in all cases of invasive breast carcinoma. Her–2 Neu amplification occurs in about one quarter to one fifth of breast cancers.13 The purpose of this study was to analyze the immunohistochemical markers in invasive carcinoma of breast and to assess the relationship of hormonal receptor status and Her2 Neuoncoprotein over expression with tumour grade.","PeriodicalId":92215,"journal":{"name":"International clinical pathology journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42080673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
