Cutaneous angiomyolipoma
Singh Kulwant,Pai Radha,Kini Hema,Kini Ullal
Indian Journal of Pathology and Microbiology , 2009,
Abstract: Cutaneous angiomyolipomas are rare. We report a case in a 45-year-old male with a well circumscribed lesion located on the chin. This lesion, probably hamartomatous in nature, differs from renal angiomyolipoma in terms of nonassociation with tuberous sclerosis, circumscription, and male predominance. Another characteristic feature is the absence of epithelioid cells. Differential diagnosis includes angiolipoma, angioleiomyoma, hemangioma, and myolipoma. It is distinguished from the abovementioned entities by the presence of a combination of thick-walled blood vessels, smooth muscle, and fat.

Morphological evaluation of cystitis glandularis
Rau Aarathi,Kini Hema,Pai Radha
Indian Journal of Pathology and Microbiology , 2009,
Abstract: Cystitis cystica and cystitis glandularis (CG) are relatively common appearances in the urinary bladder though CG may occasionally mimic a neoplasm. Microscopically, two types of CG are recognized, the usual type and intestinal type. This study was undertaken to study the morphology of CG and to highlight the differences in morphology between CG and adenocarcinoma. Eleven cases of CG were seen, of which 3 cases showed predominantly CG, usual type and eight cases showed CG of intestinal type. One case of primary adenocarcinoma was included in this study, where the adjacent bladder mucosa showed CG. Evaluation of the histological features of CG, especially intestinal type helps in correct categorization of this lesion and differentiation from adenocarcinoma of the bladder.
HIV lymphadenitis of the salivary gland: A case with cytological and histological correlation
Tiwari Avani,Kini Hema,Pai Radha,Rau Aarathi
Journal of Cytology , 2009,
Abstract: Human immunodeficiency virus infection associated lymphadenitis of the salivary glands (HIVLSG) and benign lymphoepithelial cysts are described as early events in HIV patients. The diagnosis is not usually made clinically as it mimics a salivary gland tumor. We present here a patient with two painless nodules in the right parotid and submandibular glands. The cytological diagnosis was florid reactive lymphoid hyperplasia. Histopathology revealed features of HIVLSG with multiple, small, cystic, benign lymphoepithelial lesions.
Cytological diagnosis of a rare case of solid pseudopapillary neoplasm of the pancreas
Pailoor Kirana,Kini Hema,Rau Aarthi,Kumar Yogesh
Journal of Cytology , 2010,
Abstract: A 23-year-old woman presented to our hospital with nonspecific pain in the abdomen. She underwent radiological investigations, which revealed a solid and cystic mass in the tail end of the pancreas. The mass was diagnosed to be solid pseudopapillary neoplasm of the pancreas on intraoperative scrape cytology. This was further confirmed by histopathology. The cytological diagnosis enabled appropriate surgical treatment to be planned and carried out without undue delay. It is important to distinguish this rare tumor from other pancreatic tumors with similar cytohistologic features because, if diagnosed correctly and managed surgically, this neoplasm is associated with a good prognosis.
Bone marrow biopsy in non-Hodgkin lymphoma: A morphological study
Kumar Suneet,Rau Aarathi,Naik Ramadas,Kini Hema
Indian Journal of Pathology and Microbiology , 2009,
Abstract: Context: Bone marrow (BM) biopsy is an integral part of staging work-up for non-Hodgkin lymphoma (NHL). Aims: To study the characteristics of BM involvement in NHL with respect to incidence, histologic pattern and morphology of infiltration and its discordance with the histology of primary anatomic site. Settings and Design: Forty-nine cases of NHL in which BM biopsy was performed for staging were included in this study, the primary site being classified according to the WHO classification for NHL. Materials and Methods: A prospective study of 49 cases was conducted. Bilateral BM biopsy was obtained from the posterior superior iliac spine. The biopsies were fixed in 10% buffered formalin solution and decalcified using 10% formal - formic acid for 4 - 6 h followed by routine processing. The serial sections were stained by hematoxylin and eosin and reticulin stains. Results: BM biopsy showed involvement by lymphoma in 27 cases (55.10%). Unilateral positivity was found in four cases (14.81% cases). The overall incidence of marrow involvement by NHL was 55.1%. The incidence of involvement was higher in T-cell lymphomas when compared with B-cell lymphomas and predominant pattern of involvement was mixed. Diffuse large B-cell lymphomas had the lowest incidence in all the B-cell lymphomas. A discordant histology between BM and primary anatomic site was found in 29.63% (8/27) of the cases, where it was seen more in follicular lymphomas and diffuse large B-cell lymphomas. Conclusions: Critical examination of BM biopsies can increase the diagnostic accuracy, thereby contributing to the prognosis and appropriate treatment modalities.
Giant hanging melanoma of the eyelid skin
Pai Radha,Kini Hema,Kamath Sai,Kumar Suneet
Indian Journal of Ophthalmology , 2008,
Abstract: Cutaneous melanoma of the eyelid is a rare entity. We present a 53-year-old male who had a nevus on the left upper eyelid skin since childhood, which transformed into a huge ulcerated hanging mass in the same region. Excision of the mass was done and histopathology confirmed the diagnosis of nodular malignant melanoma. A small preauricular lymph node showed metastatic melanoma on fine needle aspiration cytology.
Summaries of certain spatial patterns retrieved from multidate remote-sensing data
Hema Nair
Discrete Dynamics in Nature and Society , 2004, DOI: 10.1155/s1026022604402027
Abstract: This paper presents an approach to describe patterns in remote-sensed images utilising fuzzy logic. The truth of a linguistic proposition such as “Y is F” can be determined for each pattern characterised by a tuple in the database, where Y is the pattern and F is a summary that applies to that pattern. This proposition is formulated in terms of primary quantitative measures, such as area, length, perimeter, and so forth, of the pattern. Fuzzy descriptions of linguistic summaries help to evaluate the degree to which a summary describes a pattern or object in the database. Techniques, such as clustering and genetic algorithms, are used to mine images. Image mining is a relatively new area of research. It is used to extract patterns from multidated satellite images of a geographic area.
Transesophageal echocardiaography evaluation of thoracic aorta
Nair Hema
Annals of Cardiac Anaesthesia , 2010,
Abstract: Trans-esophageal echocardiaography is a sensitive, minimally invasive, diagnostic tool which gives real time functional image of the aorta. It helps in the diagnosis of pathologies of aorta like atherosclerosis, aneurysm and aortic dissection.
Markers for population genetic analysis of human Plasmodia species, P. falciparum and P. vivax
Hema Joshi
Journal of Vector Borne Diseases , 2003,
Abstract: Present report deals with the genetic diversity existing among the field isolates of Plasmodium falciparumand P. vivax in India. Isoenzymes and molecular markers were used to analyse field isolatesof P. falciparum and P. vivax. High level of length polymorphism was observed in repeat nucleotidesequences of MSP-1, MSP-2 and GLURP in P. falciparum isolates and CSP, GAM-1 andMSP-3α in P. vivax isolates. In study populations a high proportion of isolates (up to 60%) werecomprised of more than one genetically distinct parasite type—multiclonal. Presence of identicalallelic forms of enzyme and DNA variations in different geographical areas and in different yearssuggest that isolates belong to a single random mating population of P. vivax and P. falciparum.Observed random combination of alleles in the field isolates suggest the unlinked nature of locistudied. Study supports the feasibility of using molecular markers for the identification of recrudescencein P. falciparum from fresh infection.
