Mucoepidermoid carcinoma of the esophagus —A case report

We treated a 66-year old woman with mucoepidermoid carcinoma of the esophagus. The histologic features of this tumor seemed to originate from esophageal glands and their ducts. This deduction was based on the subepithelial growth pattern and the presence of in-situ carcinoma showing a glandular or squamous pattern at the location of the esophageal gland duct. Although the biological nature of this tumor was not elucidated, the prognosis is similar to that seen with the ordinary type of esophageal squamous carcinoma.     

The surgical management of synchronous hepatocellular carcinoma and thoracic esophageal carcinoma

A 73-year-old man was hospitalized with pathologically documented hepatocellular carcinoma and cirrhosis, and a 5.0-cm tumor located in the left lobe was resected by a left lateral segmentectomy. At the same time, metastatic squamous cell carcinoma was identified by frozen section in a perigastric lymph node in the lesser omentum. Intraoperative endoscopy revealed a 1.0-cm erosive lesion in the thoracic esophagus that was subsequently found to be primary squamous cell carcinoma. Seven weeks later, a transthoracic subtotal esophagectomy with substernal, cervical esophagogastrostomy was performed. Twenty-two months after these resections there has been no recurrence of either the hepatocellular or esophageal carcinomas.

Molecular Diagnosis in Head and Neck: What a Surgical Pathologist Must Know

Molecular alterations in tumors have become interesting targets both for diagnostic and for therapeutic and prognostic applications in tumor pathology. In the head and neck, there are a variety of different alterations, encompassing all the different types of genetic events associated with carcinogenesis. This paper reviews three different types of tumors that display a spectrum of genetic alterations: the translocation in Mucoepidermoid carcinoma, Epstein Barr virus association in nasopharyngeal carcinoma, and the HRPT2 tumor suppressor gene in parathyroid carcinoma. Basic histology is reviewed and the genetic alterations are discussed, along with a brief discussion of potential diagnostic implications.

Mucoepidermoid carcinoma of the thymus

Mucoepidermoid carcinoma of the thymus is a rare carcinoma and there is little agreement about the treatment of this tumor. According to the analysis of previously reported tumors, biologic behavior of the tumor correlated with the spread of the lesion and degree of differentiation. We report a case of this tumor in a 31-year-old man. Resection of the tumor included the left upper lobe of the lung the phrenic nerve, pericardium and disseminations in the pleura. The clinicopathological feature of this case was high-stage disease and low-grade histology. Postoperative chemotherapy and radiotherapy were performed, and the patient is alive without recurrence 14 months after surgery.

Flowcharts for the management of biliary tract and ampullary carcinomas

No strategies for the diagnosis and treatment of biliary tract carcinoma have been clearly described. We developed flowcharts for the diagnosis and treatment of biliary tract carcinoma on the basis of the best clinical evidence. Risk factors for bile duct carcinoma are a dilated type of pancreaticobiliary maljunction (PBM) and primary sclerosing cholangitis. A nondilated type of PBM is a risk factor for gallbladder carcinoma. Symptoms that may indicate biliary tract carcinoma are jaundice and pain in the upper right area of the abdomen. The first step of diagnosis is to carry out blood biochemistry tests and ultrasonography (US) of the abdomen. The second step of diagnosis is to find the local extension of the carcinoma by means of computed tomography (CT), magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), percutaneous transhepatic cholangiography (PTC), and endoscopic retrograde cholangiopancreatography (ERCP). Because resection is the only way to completely cure biliary tract carcinoma, the indications for resection are determined first. In patients with resectable disease, the indications for biliary drainage or portal vein embolization (PVE) are checked. In those with nonresectable disease, biliary stenting, chemotherapy, radiotherapy, and/or best supportive care is selected.     

Apocrine carcinoma of the breast —A case report

A case of apocrine carcinoma of the breast is reported herein. Apocrine carcinoma is a rare tumor characteristically composed of large cells with eosinophilic cytoplasm. This case involves a 34-year old woman who underwent a modified radical mastectomy and is now doing well with no evidence of recurrence, 10 months after her surgery.     

Presence of a micropapillary pattern in mucinous carcinomas of the breast and its impact on the clinical behavior

Infiltrating micropapillary carcinomas (IMPC) of breast are highly angioinvasive tumors with poor prognosis. This study is based on the observation that a similar micropapillary pattern is also observed in mucinous carcinomas of breast. About 102 mucinous carcinomas were evaluated for the presence and impact of this micropapillary pattern on the clinical behavior. Of these, 68 were mucinous carcinomas with a micropapillary pattern (MUMPC), 20 had MUMPC mixed with an infiltrating duct carcinoma component, two were solid variants of papillary carcinoma with mucin (SVPCMU), five had collision of the MUMPC and SVPCMU patterns and seven were mucinous carcinomas with signet ring cells (MUS). The factors negatively affecting overall survival (OAS) and disease-free survival (DFS) included the histological type of mucinous carcinoma, nodal metastases, an irregular tumor border, <50% mucin and an IMPC type of local recurrence or metastases. In the multivariate analysis, the histologic type of mucinous carcinoma and an irregular tumor border were most significant for OAS and DFS. Thus, 86% of mucinous carcinomas in this study were mucinous variants of the angioinvasive infiltrating micropapillary carcinomas. These tumors can produce IMPC type of metastases and thus should be treated aggressively.     

Small cell carcinoma of the cystic duct: A case report

Small cell carcinoma usually involves the lung and rarely affects the biliary tract, especially the cystic duct. In this article we report a case of small cell carcinoma of the cystic duct in a 46-year-old Japanese man. The patient presented with abdominal pain and jaundice. Imaging showed a small nodule in the cystic duct invading the common bile duct with dilatation of the proximal biliary tree. The hepatic artery and portal vein were free from invasion. Extended right hepatic lobectomy, cholecystectomy, and resection of the extrahepatic proximal bile ducts were performed together with lymph node dissection under the tentative diagnosis of carcinoma of the cystic duct. Histopathologic examination of the resected specimen revealed small cell carcinoma arising in the cystic duct and extending into the common bile duct. The postoperative clinical course was uneventful, and the patient is doing well without any signs of recurrence 1 year after the operation. To our knowledge this is the first documented case of a small cell carcinoma arising in the cystic duct.

Adenoid cystic carcinoma of the esophagus: Report of a case

The case of a 70-year-old Japanese woman with adenoid cystic carcinoma (ACC) of the esophagus is presented herein. The patient presented with progressive dysphagia, and an upper gastrointestinal series and esophagogastroscopy revealed a protruding tumor located in the middle portion of the esophagus. Ultrasonography (US) and computed tomography (CT) suggested a lymph node metastasis between the left lobe of the liver and the esophagocardiac junction. Histopathologic examination of a biopsy specimen showed squamous cell carcinoma (SCC) and a subtotal esophagectomy was performed under the preoperative diagnosis of esophageal carcinoma. However, the histopathologic diagnosis of the resected specimen proved to be ACC of the esophagus with a lymph node metastasis around the left gastric artery. We report the clinicopathological findings of this case and briefly discuss the clinical implications of ACC.     

Clinico-pathological features of bladder carcinoma: Experience from a tertiary care hospital of Pakistan

Bladder carcinoma is most common urological malignancy in Pakistan. The objective of the study was to determine the clinico-pathological characteristics of histologically confirmed bladder carcinoma at a tertiary care hospital of South Punjab, Pakistan. Methods: In two hundreds and twenty one patients (172 male and 49 female) bladder carcinoma was diagnosed from Jan 1998 to June 2005. All patients were evaluated with regards to clinical presentation, cystoscopic findings and histo-pathological data. Results: Male female ratio was 3.5:1. The median age was 58 years (range 18–87 years). 65% men had history of cigarette smoking while 51% women had long history of smokeless tobacco (nasal snuff or chewable) use. Most patients presented with painless hematuria. Primary transitional cell carcinoma was the most common (i.e. 96%) histological variety of bladder carcinoma. 63% patients had muscle invasive disease at the time of presentation. Even in superficial bladder carcinoma, most patients had invasion of lamina propria (pT1 disease). Conclusion: More than 90% of primary bladder carcinoma are of transitional cell variety and over 60% having muscle invasive disease at the time of diagnosis. Even in patients with superficial disease, majority (i.e. 98%) have invasion of lamina propria.     

Breast Intracystic Papillary Carcinoma: An Update

Abstract:  Intracystic papillary carcinoma (IPC), a breast tumor mainly occuring in the elderly, has long been considered as a variant of ductal carcinoma in situ (DCIS). This is now debated since metastatic cases have been reported. In this study, surgical pieces of 20 IPCs were reassessed, and markers of myopepithelial layer (p63, CD10 and Smooth Muscle Actin) as well as estrogen receptors (ER) and progesterone receptors (PgR) and C-erb-B2 oncoprotein expression were systematically performed and quantified. In 10 cases, an associated unequivocal invasive component was found. In all 20 cases, no myoepithelial layer was found. Eighteen tumors were ER positive, 14 were PgR positive. Moreover, none of the tumors over-expressed C-erb-B2 oncoprotein. Therefore this study showed that in all cases of IPC there were microscopic features of invasive carcinoma despite good clinical prognostic indicators, and that precise characterization of tumors requires extensive paraffin embedding of surgical pieces.     

Significance of Linear Extent of Breast Carcinoma at Surgical Margin

Background: Our objective was to correlate the extent of margin positivity and the findings on re-excision specimens of infiltrating mammary carcinoma.Methods: We selected 50 consecutive cases of infiltrating mammary carcinoma, including both infiltrating ductal carcinoma and infiltrating lobular carcinoma, with positive margins followed by re-excision. Margin positivity was defined as the presence of cancer at the inked margin. The extent of margin positivity was assessed by measuring the linear involvement of the inked margin by the carcinoma.Results: Twenty-one of 50 cases (42%) showed positive findings on re-excision, including either infiltrating carcinoma or carcinoma in situ or both. Nine of 14 cases (64%) with ductal carcinoma in situ or infiltrating ductal carcinoma on re-excision and 4 of 7 cases (57%) with lobular carcinoma in situ or infiltrating lobular carcinoma on re-excision had initial linear margins >1.0 cm, whereas 28 of 29 cases (96%) with negative findings on re-excision had initial linear margins &<1.0 cm.Conclusions: Linear measurement of the inked margin involved by infiltrating mammary carcinoma can be used as a predictor of findings on re-excisions.     

Ber-EP4, CK1, CK7 and CK14 are Useful Markers for Basaloid Squamous Carcinoma: A Study of 45 Cases

Diagnosis of basaloid squamous carcinoma (BSCC) currently relies mainly on histological criteria, with variable immunohistochemical results reported in small series. We explored the use of a battery of immunohistochemical stains to elucidate this diagnosis on 45 cases of BSCC. To further elucidate the immunohistochemical profile of BSCC, to explore potential genetic pathways of malignant transformation using proliferation markers, and to investigate a possible link with Human Papillomavirus (HPV). Forty-five cases of BSCC and 34 site-matched cases of squamous cell carcinoma (SCC) were obtained from the archives of the pathology department at our institution. Extensive literature review was undertaken utilizing Medline. Ber-EP4 is a useful diagnostic marker for BSCC, positive in 82% (37/45) of the cases and in 68% (23/34) of SCC. An alternative is the combination of cytokeratins CK14 and CK7, known to be negative, and CK1, known to be positive, which achieves an accuracy of 73% (33/45) in BSCC and 88% (30/34) in SCC. The two diagnostic approaches were in agreement in 66% of the cases; both methods were equally accurate in the divergent cases. Increased expression of the proliferation markers supports the concept that BSCC is a rapidly growing tumor. Results of p16 stains support an etiological link between BSCC and HPV; interestingly, HPV was present significantly more in BSCC (71% (32/45)), than in SCC (59% (20/34)) in this study (P = 0.02). This data has been presented, in abstract form, at the 2008 United States and Canadian Academy of Pathology Annual Meeting, March 4, in Denver, Colorado.
