RESUMEN

Papillary carcinoma is the most common malignant tumor of the thyroid, especially in countries with adequate or excess iodine in diet. Many studies indicate that a sizable number of papillary cancer cases occur in a setting of chronic thyroiditis. But the tumor that arises more frequently in thyroiditis is malignant lymphoma. We report a rare association of papillary carcinoma of thyroid in an elderly lady with adult T-cell lymphoma/leukemia. Fine needle aspiration of the thyroid, neck nodes and evaluation of the bone marrow and peripheral blood helped in the diagnosis of papillary cancer coexisting with adult T-cell lymphoma/leukemia.

RESUMEN

Five hundred endometrial specimens were studied to document the changes in blood vessels in various phases of menstrual cycle, menstrual disturbances and in unexplained infertility. Sixty-three cases were taken as control and 437 cases as study group which included cases of dysfunctional uterine bleeding (DUB), endometrial polyps, fibroids, adenomyosis, infertility and atrophic endometrium. Using light microscopy, the vascular morphology was studied. The blood vessels were concentrated more in basal layer in the proliferative phase and in functional layer in the secretory phase. Cases of complex hyperplasia and pill endometrium had significantly higher vessel concentration. Congestion and dilatation of blood vessels were significantly higher in cases of DUB. The present study showed a positive correlation between endometrial angiogenesis and menstrual disorders. The alteration in blood vessel morphology has significant role in prognosis and in various anti-angiogenic therapies.

RESUMEN

Solitary rectal ulcer syndrome is a rare disorder of childhood and usually goes unrecognised or misdiagnosed because it can mimic various other rectal entities. Here a 9-year old boy presented with bleeding per rectum and altered bowel habits. Colonoscopy revealed multiple ulcers which on histopathological examination showed features of SRUS with severe reactive changes of regeneration mimicking malignancy.

RESUMEN

The aim of the study is to compare the histologic quality of the microwave histoprocessing with that of conventional method and to determine its positive impact on turnaround times and reduction of costs of tissue processing. One hundred and eighty-five paired tissue sections from different organs were taken. Each tissue sections were of size of 15 mm x 10 mm x 3 mm and divided into two; one set as experimental group and the other as control group. The tissues in the experimental group were further divided into six groups and processed by vacuum-microwave method according to six protocols from I to VI. Other tissues in the control group were processed by the conventional method and compared. Overall, the quality of microscopic tissue from both the methods was identical. Microwave processing shortened the time of processing without compromising the overall quality of the histologic section and was cost-effective.

RESUMEN

A 46-year-old man had primary pulmonary symptoms of intermittent fever, cough and dyspnoea. Radiological investigations revealed a mass at right hilum with right upper lobe collapse. Bronchoscopy showed a luminal mass of which the biopsy showed a tumour with predominantly clear cell change. Subsequent investigations revealed primary renal adenocarcinoma. The differential diagnosis of clear cell lung tumour is discussed. This case of endobronchial metastasis from renal cell carcinoma is being presented because of its rarity.
