Ovarian Steroid Cell Tumour: Correlation of Histopathology with Clinicopathologic Features

Ovarian steroid cell tumours (not otherwise specified) are rare neoplasms of the ovary and are classified under lipid cell tumours. Their diagnosis can be considered as one of exclusion. Histopathologically, the tumour should carefully be evaluated for microscopic features of malignancy, but it is essential for the clinician and the pathologist to remember that in these tumours, pathologically benign histomorphology does not exclude the possibility of clinically malignant behaviour. Our case study focuses on the comparative findings in a postmenopausal female diagnosed with an ovarian steroid tumour (not otherwise specified). A careful correlation between clinical and surgical evaluation and microscopic analysis is necessary, as is a regular followup

Trabecular variant of juvenile aggressive ossifying fibroma

Juvenile aggressive ossifying fibroma (JAOF) is an uncommon benign lesion which is distinctly aggressive in behavior with high tendency for recurrence. It appears in early age and in 79% of patients is diagnosed before 15. It has two histological variants: psammomatoid and trabecular, with the latter being less common with a stronger tendency to recur. In this article, we present a case of trabecular JAOF, in which treatment could not be given despite the availability of all requisites for surgery and good financial status, due to parental indifference and negligence

Cytological diagnosis of multiple myeloma presenting as a jaw swelling

Multiple myeloma is a systemic B-cell lymphoproliferative disease with varied manifestations. Its diagnosis can therefore pose difficulties for both the clinicians and pathologists. Jaw lesions, though not uncommon, rarely present as the first sign in multiple myeloma. We present here the case of a 45 year-old female who presented with a swelling of the jaw and on subsequent work-up, was diagnosed with multiple myeloma. Recent research regarding this disease has also been highlighted

Evaluation of AgNOR scores in aspiration cytology smears of breast tumors

<b>Aim: </b> The aim of this study is to assess the difference in the silver-stained nucleolar organizer regions (AgNOR) scores on aspiration smears from benign and malignant breast tumors, and to determine the feasibility of AgNOR staining as part of the cytological investigation of breast tumors. <b> Settings: </b> AgNOR scores were evaluated on aspiration smears and tissue sections from 42 breast tumor cases. <b> Materials and Methods:</b> Smears from 27 breast tumor cases and tissue sections from 15 surgically resected specimens were examined. Counting was performed on a small number of tumor cells (50 cells). Both the mean (mAgNOR) score and the AgNOR proliferative index (pAgNOR index) were assessed for each specimen. <b> Statistical Analysis:</b> Statistical evaluation was carried out using the Students&#x2032; &#x2032;t&#x2032;-test. The result was considered significant when <i>P</i> &lt; 0.05. <b> Results and Conclusions:</b> The mAgNOR score and pAgNOR index were significantly higher in smears from malignant tumors than in those from benign tumors (<i>P</i> = 0.01). These results were similar to those obtained for tissue sections and were comparable to established data. The determination of AgNOR scores on cell smears in a limited cell population has practical advantages

Trichogranuloma of the external auditory canal mimicking aural polyp: A rare case report

We report a case of an 18-year-old male who presented to us with complaints of decreased hearing, ear discharge, and fullness in the right ear for last 2 months. Examination revealed a swelling of 0.5 cm × 0.5 cm in the inferior part of the external acoustic canal, tympanic membrane was found to be normal. Patient was advised antibiotic and steroids ear drops after making a provisional diagnosis of aural polyp. Surgical excision of the swelling was done when conservative treatment was unsuccessful. The excised polyp was sent for histopathological examination which revealed presence of foreign body giant cells and mixed inflammatory infiltrate around the fragments of hair shafts which confirmed the diagnosis of trichogranuloma in the external auditory canal. Owing to the rarity of such location of trichogranuloma, this case is being reported here

Retiform hemangioendothelioma of the gluteal region: A case report

Retiform hemangioendothelioma is a locally aggressive, rarely metastasizing, low-grade angiosarcoma characterized by intercommunicating vascular channels lined by hobnail or cuboidal endothelial cells, flanked by lymphocyte and hyaline sclerosis. Neoplastic endothelial cells usually express von Willebrand factor, CD31 and CD34, while the lymphocytic infiltrate shows a mixture of CD3+, T and CD20+ B cells. The authors describe a case of a 76-year-old female who presented with a soft, painless, ill-defined mass measuring 9 cm in her right gluteal region for the past 15 years, clinically suggestive of a lipoma. There was no regional lymphadenopathy. The mass was resected and sent for histopathological examination. The slow-growing lesion and the typical histomorphology led to the diagnosis of retiform hemangioendothelioma. The diagnosis was confirmed by immunohistochemistry using CD34 antibody, which strongly stained the endothelial cells. The patient was followed up for 6 months after the surgery and no recurrence was noted

FNAC diagnosis of medullary carcinoma thyroid: A report of three cases with review of literature

Medullary carcinoma of the thyroid is an unusual neoplasm, which is associated with specific supportive diagnostic markers. Despite this, its cytological diagnosis is often difficult. We report herewith three cases of medullary thyroid carcinoma. The diagnosis was established on fine-needle aspiration cytology. Plasmacytoid cell pattern was observed in two cases and spindle cell pattern in the third case

Spindle-cell ameloblastic carcinoma of the maxilla with adenoid cystic carcinoma-like areas: A new variant?

Ameloblastic carcinoma is a rare aggressive malignancy of odontogenic epithelial origin. The disease has been reported to afflict people over a wide range of age group without any sex predilection. It is characterized by rapid growth and destruction of overlying bones along with involvement of adjacent soft tissues. The overall prognosis of this cancer is poor despite radical surgery and radiotherapy. Owing to the rarity of this lesion, complete data on the biological behavior and response to different treatment modalities are still lacking. The authors hereby report a case of this uncommon tumor arising from left maxilla in a 60-year-old Indian male. Histopathological examination of the tumor showed foci of spindling intermixed with large areas of tumor cells arranged in cribriform pattern and having luminal eosinophilic material which was reminiscent of adenoid cystic carcinoma. A final diagnosis was achieved after immunohistochemical study. These unusual findings prompted this case report

Atypical Proliferating Clear Cell Adenofibroma of the Ovary: A Case Report

Clear cell adenofibromas of borderline malignancy are extremely rare tumors of theovaries. They may be associated with ovarian clear cell adenocarcinomas which typically present as large adnexal masses and are generally considered highly malignant. We describe the case of a postmenopausal female with an ovarian mass diagnosed as atypical (borderline) proliferating clear cell adenofibroma. The patient is alive and wellwithout signs of recurrence three years after surgery

Utility of cytospin and cell block technology in evaluation of body fluids and urine samples: A comparative study

Background: Cytologic examination of body fluids commonly involves the use of direct or sediment smears, cytocentrifuge preparations, membrane filter preparations, or cell block sections. Cytospin and cell block techniques are extremely useful in improving cell yield of thin serous effusions and urine samples, and ensure high diagnostic efficacy. Materials and Methods: We studied cytospin preparations and cell block sections prepared from 180 samples of body fluids and urine samples to compare the relative efficiency of cell retrieval, preservation of cell morphology, ease of application of special stains, and diagnostic efficacy. Samples were collected and processed to prepare cytospin smears and cell block sections. Results: We observed that overall, cell yield and preservation of individual cell morphology were better in cytospin preparations as compared to cell blocks, while preservation of architectural pattern was better in cell block sections. The number of suspicious cases also decreased on cell block sections, with increased detection of malignancy. It was difficult to prepare cell blocks from urine samples due to low cellularity. Conclusions: Cytospin technology is a quick, efficient, and cost-effective method of increasing cell yield in hypocellular samples, with better preservation of cell morphology. Cell blocks are better prepared from high cellularity fluids; however, tissue architecture is better studied, with improved rate of diagnosis and decrease in ambiguous results. Numerous sections can be prepared from a small amount of material. Special stains and immunochemical stains can be easily applied to cell blocks. It also provides a source of archival material
