Research paper thumbnail of Primary Synovial Sarcoma of the Pharynx: A Series of Five Cases and Literature Review

Although synovial sarcoma has been reported in practically every organ, the extremities are the commonest site of occurrence followed by the head and neck. Primary synovial sarcoma of the pharynx is rare and only case reports have been published. We report a series of five cases of primary synovial sarcoma involving the pharynx.

Research paper thumbnail of Sinonasal teratocarcinosarcoma: a clinicopathologic and immunohistochemical study of 6 cases

Patients are predominantly adults with a male predominance. The aim of this study was to describe clinicopathologic and immunohistochemical features of 6 cases of TCS. The ages ranged from 18 to 67 years (mean, 33 years) with a male-to-female ratio of 5:1. Most tumors were located in the nasal cavity. Nasal obstruction and epistaxis were the common presenting symptoms. Histologically, all tumors exhibited a heterogeneous morphology with varying proportions of benign and malignant epithelial, mesenchymal, and neuroepithelial elements. Adenocarcinoma was the malignant epithelial component in all cases. The mesenchymal elements were composed of benign to malignant spindle cells. Osteosarcomatous areas were seen in 2 cases and rhabdomyosarcoma in 1 case. Rhabdoid differentiation was also seen in 1 case. Immunohistochemical stains CKAE1/AE3 and CK Cam 5.2 were positive in the epithelial elements, vimentin in mesenchymal, and CD56 and neuron-specific enolase in neuroepithelial elements. Follow-up was available in 4 patients and ranged from 21 to 40 months (mean, 31 months). Lung and dura metastasis, respectively, were seen in 1 patient each. However, all 4 patients are alive and free of disease to date. In conclusion, TCS is a rare but highly malignant tumor with aggressive behavior characterized by benign and malignant epithelial, mesenchymal, and neuroepithelial components. Two patients in our series were younger than 20 years. The occurrence of rhabdoid differentiation and osteosarcomatous component seen in our series were rarely described in literature. Recognition of all the components requires adequate sampling, which is crucial for a correct diagnosis.

Research paper thumbnail of How our practice of histopathology, especially tumour pathology has changed in the last two decades: reflections from a major referral center in Pakistan

Asian Pacific journal of cancer prevention : APJCP, 2014

Continued advances in the field of histo-pathology (and cyto-pathology) over the past two decades... more Continued advances in the field of histo-pathology (and cyto-pathology) over the past two decades have resulted in dramatic changes in the manner in which these disciplines are now practiced. This is especially true in the setting of a large university hospital where the role of pathologists as clinicians (diagnosticians), undergraduate and postgraduate educators, and researchers has evolved considerably. The world around us has changed significantly during this period bringing about a considerable change in our lifestyles and the way we live. This is the world of the internet and the world-wide web, the world of Google and Wikipedia, of Youtube and Facebook where anyone can obtain any information one desires at the push of a button. The practice of histo (and cyto) pathology has also evolved in line with these changes. For those practicing this discipline in a poor, developing country these changes have been breathtaking. This is an attempt to document these changes as experienced ...
