The patient was treated by tumor excision with wide margins. Pathologically, the margins were negative for tumor cells. The patient is now healthy 1 year after the excision. The tumor measured 3 cm × 2 cm × 2 cm and arose from the epidermis. The percentage of the occupying area was 60% in BCC, 20% in SCC, and 20% in PC. Histologically, BCC was characterized by basalioma cells, melanin pigmentation, peripheral palisading, and cleft formation, SCC by ample acidophilic cytoplasm, individual keratinization and cancer pearls, and PC by poroma cells and tubular structures containing cuticles. Cystic changes in BCC and SCC, keratotic nature of BCC, and acatholytic features of SCC were also seen in places. There were gradual merges among the three components. Immunohistochemically, BCC component was characterized by strong and diffuse expression of KIT, PDGFRA and p63, weak expressions of cytokeratin (CK) AE1/3, CK CAM5.2, CK34BE12, and negative expressions of CK18, CK19, CEA and CA19-9. SCC component was characterized by strongly positive expressions of p63, CEA, CK34BE12, CK7 and CK8, and negative expressions of CK18, CK19, and CA19-9. PC was characterized by strongly positive expressions of KIT, PDGFRA, CK34BE12, CK7, CK8, CK18, CK19, CEA, S100 protein, CA19-9, MUC1, and negative expression of p63. The present case revealed that there are primary cutaneous keratinocytic primordial carcinomas with triple differentiations into BCC, SCC, and PC. The present case is the first example of such tumors. It is thought that KIT and PDFRA-positive stem cells or cancer stem cells in the BCC component give rise to the SCC and PC components in the present case.","PeriodicalId":90463,"journal":{"name":"Case reports in clinical pathology","volume":"4 1","pages":"7"},"PeriodicalIF":0.0,"publicationDate":"2016-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/crcp.v4n1p7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71210894","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}

After 12 years, he developed lymphadenopathy and had an axillary lymph node biopsy which showed transformation to Diffuse Large B-cell lymphoma (DLBCL) with background FL. The patient was treated with chemotherapy and his course was complicated by cellulitis/abscess formation of the right thigh. Computerized Tomography scan showed a large necrotic nodal conglomerate within the right inguinal region measuring 7.8 cm × 5.1 cm and an excisional biopsy was performed. The lymph node architecture was effaced by sheets of large, atypical, pleomorphic cells with open/vesicular chromatin and scattered prominent nucleoli. Focal areas showed residual/recurrent FL, grade I-II. Immunohistochemical stains showed that the large neoplastic cells express CD4, CD68, CD163, BCL-6, lysozyme, CD45 and S-100. The morphologic and immunophenotypic findings are consistent with histiocytic sarcoma (HS). Fluorescence in-situ hybridization studies of the HS showed translocation t(14;18)(q32;q21), a gene rearrangement involving 3q27(BCL6), and gain of 14q32(IgH). The patient’s prior FL and DLBCL were shown to have the same translocation t(14;18)(q32;q21). The molecular findings show a common cell lineage between all three diagnoses confirming that FL can transform into DLBCL and transdifferentiate into HS.","PeriodicalId":90463,"journal":{"name":"Case reports in clinical pathology","volume":"3 1","pages":"45"},"PeriodicalIF":0.0,"publicationDate":"2016-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/CRCP.V3N4P45","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71210036","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}

Case: A 10-year-old girl was referred to us from the emergency ward with the complaints of abdominal pain and vomiting. After detailed examination, we decided to conduct an abdominal exploration in suspicion of potential acute appendicitis. During the laparotomy, an acute simple appendicitis was found and appendectomy was performed. We further explored the abdomen to rule out a possible Meckel diverticulitis, during which an ileal intraluminal mass was palpated about 10 cm proximal to the intestinal ileocecal valve. We performed enterotomy and resected the polypoid mass completely. The histopathological reports were lymphoid hyperplasia for the appendicitis and intestinal hyperplastic polyp for the polypoid mass. Follow up of the patient after 6 months was eventless. Conclusions: Comorbidities like intestinal polyps should be part of the considerations during the abdominal explorations for acute appendicitis. Missing an ileal polyp may lead to a second operation.","PeriodicalId":90463,"journal":{"name":"Case reports in clinical pathology","volume":"3 1","pages":"37"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/CRCP.V3N4P37","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71209931","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}

A 68-year-old man presented with dysuria. Laboratory data did not indicate malignancy in the prostate with serums PSA of 4.6 ng/ml. Imaging techniques identified no tumors and lympho-adenopathy other than the prostatic enlargement. The patient was clinically diagnosed as prostatic hyperplasia, and trans-urethral resection of prostate (TURP) (65 g) was done. Histologically, the TURP-specimens showed severe nodular proliferation of atypical small lymphocytes consisting of small centrocytic lymphocytes and large centroblastic lymphocytes, the number of the latter being 2/HPF. Immunohistochemically, the tumor cells and nodular areas were positive for CD45, CD20, CD79a, bcl-2, bcl-6, and CD10. They were negative for pan-cytokeratin (AE1/3, CAM5.2), CD3, CD45RO, CD56, PSA, chromogranin-A, synaptophysin, NSE, CD138, CD15, CD30 and cyclin D1. No significant number of plasma cells were seen by immunohistochemistry for light chains and CD138. A pathological diagnosis of primary FL (grade 1) of the prostate was made. No tumors were identified by various imaging techniques, and the prostatic FL was diagnosed as primary.
