Primary hepatic lymphoma: A case report.

Primary non-Hodgkin lymphoma of the liver is a very rare malignancy. In this case report, we describe a case of primary hepatic lymphoma (PHL) in a 60-year-old man who presented with lump and pain in the abdomen of 2 months' duration. The patient had altered liver function, normal serum alfa fetoprotein level (AFP), normal hemogram and bone marrow.

Atypical carcinoid of the esophagus.

Occurrence of carcinoid tumors in the esophagus is exceedingly rare. We present a case of an atypical carcinoid in the mid esophagus in a 56-year-old male, presenting with dysphagia. Esophagectomy was performed followed by postoperative chemotherapy.

Axillary node metastasis from primary ovarian carcinoma.

Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion.

Cancer stem cells and stemness markers in oral squamous cell carcinomas.

Head and neck squamous cell carcinoma (HNSCC) is one of the world top ten most common cancers with its highest occurrence in the Indian subcontinent and different aggressive and etiological behavioural patterns. The scenario is only getting worst with the 5 year survival rates dropping to 50%, persistent treatment failures and frequent cases of relapse/recurrence. One of the major reasons for these failures is the presence of cancer stem cells (CSCs), a small population of cancer cells that are highly tumourigenic, capable of self-renewal and have the ability to differentiate into cells that constitute the bulk of tumours.

Evaluation of central nervous system metastases with immunohistochemistry correlation.

Context: Brain metastases are the most common intracranial neoplasms. They are often the first symptom of systemic malignancy. Hence, immunohistochemistry (IHC) is of importance in evaluating the origin of brain metastases.

Plasma cell leukemia: a retrospective study of 10 cases.

Background: Plasma cell leukemia (PCL) is a rare aggressive variant of multiple myeloma (MM) characterized by a fulminant course and poor prognosis. Flow cytometry (FCM) is very useful in the diagnosis of the plasma cell leukemia. Herein, we present 10 cases of PCL.

Granular cell ameloblastoma of mandible.

Ameloblastoma is a neoplasm of odontogenic epithelium, especially of enamel organ-type tissue that has not undergone differentiation to the point of hard tissue formation. Granular cell ameloblastoma is a rare condition, accounting for 3-5% of all ameloblastoma cases. A 30-year-old female patient presented with the chief complaint of swelling at the right lower jaw region since 1 year.

Small cell variant of renal oncocytoma with liver metastases: a case report.

Renal oncocytoma is a renal neoplasm considered to be benign. A small cell variant comprising predominantly of oncoblasts is rare. Metastases from a renal oncocytoma are extremely rare.

Nasopharyngeal metastasis of follicular carcinoma of the thyroid with extensive clear cell change: a case report.

Thyroid carcinoma metastatic to the maxillofacial area is extremely rare. Other carcinomas can metastasize to this area, but very few cases of follicular thyroid carcinoma metastasizing to the nasopharynx have been reported. Carcinoma from the kidney, liver, large bowel, prostate, and thyroid are known to have the potential for clear cell differentiation, and all of them can metastasize to the sinonasal area.

Cytokeratin and vimentin expression in breast cancer.

Background: The transition from epithelial keratin to mesenchymal vimentin expression marks an important step in the malignant progression of breast cancer. This study analyzed the clinical significance of cytokeratin and vimentin in patients with breast cancer.

Materials And Methods: Expression of cytokeratin and vimentin was evaluated by immunohistochemistry on paraffin-embedded tissue sections of patients with breast cancer.

Flow cytometric DNA analysis for determination of malignant potential in adrenal pheochromocytoma or paraganglioma: an Indian experience.

Background: We analyzed the histological features and DNA flow cytometric results in 34 patients with pheochromocytoma and paragangliomas and attempted correlation with the biological behavior for determination of the malignant potential of these tumors.

Methods: DNA analysis was done on a FACSort flow cytometer using paraffin-embedded tissues. Histopathological analysis was performed using parameters, i.
