Enteropathy associated T cell lymphoma (EATL) is a rare type of T-cell lymphoma, often associated with a history of celiac disease. It usually arises in the jejunum, but can involve other gastrointestinal tract sites such as stomach and colon. Monomorphic variant of EATL often occurs without a history of celiac disease, has variable histologic evidence of enteropathy, and is usually CD56+. We report a case of EATL in a 49-year-old female presenting as bilateral ovarian masses. The morphology and immunophenotypic features were compatible with monomorphic variant of EATL.

Melanotic neuroectodermal tumor of infancy or melanotic progonoma is an uncommon tumor, presenting in infants. The epididymis and testis are rare sites of occurrence. This tumor can be confused with round cell tumor (RCT). Since the treatment modality and prognosis of melanotic progonoma and RCT are very different, it is imperative to make a correct diagnosis.

BACKGROUND: The microscopic features of medullary carcinoma have been described in world literature, together with its behavior and molecular biology. However, no large study has been reported from India. AIMS: This study aims to analyse the clinical, and especially the pathological features of medullary carcinoma of the thyroid, and the surrounding thyroid. MATERIALS AND METHODS: In this study a total of 234 cases of medullary thyroid carcinoma (MTC) were gathered over a period of 3 decades. The clinical presentation, the microscopic features and the clinical outcome were analyzed. RESULTS: MTC was found to be twice as common in men as in women and for some reason it occurred 10 years earlier in women. The histology revealed certain interesting features like the presence of apoptosis in over half of the tumors, in addition to the other common and not so common histological findings (encapsulated variant, small cell variants, follicular pattern, rosettes, oncocytic change, osteosarcoma-like pattern, and cribriform pattern). The adjacent thyroid in about 19% of the cases showed optically clear nuclei in the follicles that were close to the tumor cells. These features were similar to those seen in papillary thyroid carcinoma. CONCLUSIONS: The thyroid adjacent to MTC showed nuclear changes, which are also found in papillary carcinoma of the thyroid. The occasional concurrent occurrence of these two tumors and the involvement of the RET gene in both medullary and papillary carcinomas, makes this observation worth discussing and studying further.

Papanicolaou (Pap) staining procedure has achieved worldwide acceptance in cytology practice due to its crisp cytological details. There are many centres or private laboratories in our country which cannot fulfill the economic requirement of Pap staining and hence employ comparatively cheaper haematoxylin and eosin (H & E) stain. Although routine H & E cannot replace Pap, this study is an attempt to modify H & E staining that would offer comparable diagnostic results. The present study is restricted to FNAC material from palpable lesions i.e.breast and lymph nodes. For this purpose 50 lymph nodes ( LN) and 18 breasts were aspirated. Out of two fixed smears, 1 was stained by Pap technique for routine reporting and other by modified H & E method which was examined and reported by other pathologist, Dr.Sangeeta B.Desai ( SBD) The diagnosis of both the techniques were compared. Emphasis was also given on cytomorphological characteristics. Out of fifty lymph node aspirates from various sites, no diagnostic discrepancy was observed in 46 cases. Three out of 4 had sampling errors whereas, poor nuclear staining was noticed in a single case. Out of eighteen breast aspirates concordant diagnosis was achieved in 16 cases. Out of two discrepant diagnosis 1 was due to sampling error, and the other was an interpretative error. All the cases were confirmed histologically. In conclusion, modified H & E staining is useful for common sites of aspirations of superficial lesions.

The prognosis and overall outcome of solid growth pattern in differentiated papillary carcinoma of thyroid is controversial. While general consensus suggest outcomes similar to typical papillary carcinomas others demonstrate a more aggressive biology. We present a case of differentiated papillary carcinoma of thyroid with solid growth pattern presenting with neck swelling and widespread skeletal metastases. The areas of bone lesions showed avid 131I concentration on a postoperative large dose 131I whole body scan and was treated with 131I subsequently. The present case suggest that the solid architecture in a papillary thyroid carcinoma may be indicative of an aggressive clinical course, contrary to the common opinion that it does not adversely influence its biologic behaviour and thus emphasize the need to reexplore the prognostic significance of histopathologic subclassification along with an assessment of histologic grade and expression of molecular risk factors in this particular tumour subtype.
