Utility of cytomorphology in distinguishing solid pseudopapillary neoplasm of pancreas from pancreatic neuroendocrine tumor with emphasis on nuclear folds and nuclear grooves.

Pancreatic solid pseudopapillary tumor (SPN) and pancreatic neuroendocrine tumors (Pan-NET) have close resemblance on imaging and cytomorphology, though they differ in their prognosis and treatment strategy. SPNs are low-grade indolent tumors while Pan-NETs harbor malignant potential with propensity to metastasize. We aim to differentiate SPN from Pan-NET based on cyto-morphology; to classify nuclear membrane (NM) irregularities or nuclear folds into four grades and see whether they bear any difference with...

Sclerosing mucoepidermoid carcinoma with eosinophilia of the thyroid: Case report of a rare lesion with novel genetic mutation.

Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) is a rare primary cancer of the thyroid. This tumor is analogous to other primary tumors of the salivary glands, breast, pancreas, and esophagus. We present a case of this rare tumor with characteristic clinical features, ultrasound images, cytopathology, histopathology, and a heretofore undocumented somatic gene mutation. Additionally, we provide a succinct review of the controversial literature for this uncommon lesion.

Predictive value of the anal cytology for detecting anal intraepithelial neoplasia or worse: A systematic review and meta-analysis.

Anal intraepithelial neoplasia (AIN) refers to a precancerous lesion of anal squamous cell carcinoma (SCC). Human papillomavirus (HPV) is considered a crucial risk factor for AIN. Individuals with high-risk sexual behaviour, such as receptive anal intercourse and multiple sexual partners, as well as men who have sex with men exhibit a relatively high rate of AIN. The anal cytology is a screening method for AIN in high-risk individuals, and patients with abnormal anal cytology may benefit from high-resolutio...

Role of fine-needle aspiration in post liver transplant patients: A clinical/cytological review.

Fine-needle aspiration (FNA) of superficial and deep-seated lesions has been used with high sensitivity and specificity in the diagnosis of neoplastic and nonneoplastic lesions. However, literature of FNA in posttransplant patients is sparse, especially in postliver transplant. We undertook a retrospective study to evaluate the utility of FNA in the clinical management of post liver transplant patients.

Diagnostic utility of immunohistochemical analysis and Epstein-Barr virus-encoded small RNAs in situ hybridisation of cell block sections obtained using fine-needle aspiration in nasopharyngeal carcinoma with lymph node metastasis.

This study aimed to investigate the diagnostic utility of immunohistochemistry (IHC) analysis (FNA) and Epstein-Barr virus- (EBV) encoded small RNAs (EBERs) in situ hybridisation analyses of cell block (CB) sections obtained using fine needle aspiration in nasopharyngeal carcinoma (NPC) with lymph node metastasis.

Imprint cytology of biphenotypic sinonasal sarcoma of the paranasal sinus: A case report.

Biphenotypic sinonasal sarcoma (BSNS) is a rare low-grade spindle cell sarcoma that predominantly affects middle-aged women with multiple tumors in the sinonasal tract. BSNS shows biphenotypic expression of neural and myogenic markers on immunohistochemistry (IHC) with a specific chimeric PAX3-MAML3 fusion. The cytological features of BSNS have so far not been reported. Here, we describe a case of BSNS including findings of imprint cytology, histology, IHC, and genetic analysis. A 30-year-old woman presente...

Pleomorphic and atypical multinucleated giant cells in solid pseudopapillary neoplasm of pancreas: A diagnostic pitfall in cytology and a review of the literature.

Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low-grade malignancy typically occurring in young women. Occasionally, these neoplasms present with pleomorphic to atypical multinucleated giant tumor cells which may mimic high-grade malignancy. Our patient is a 25-year-old male who presented with one year of intermittent epigastric pain. Magnetic resonance imaging showed a 3.1 × 2.5 cm mass in the pancreas body. Endoscopic ultrasound-guided fine needle aspiration of the mass showed large ...

Cell block cellularity: A comparison of two fixatives and their impact on cellularity.

Ancillary testing including immunohistochemistry and molecular diagnostics has become an increasingly important component for the evaluation of cytologic specimens. Ancillary testing is important not only for diagnosis but also for predictive and prognostic evaluation. While a number of substrates are appropriate for ancillary testing, cell block specimens are commonly utilized and the success of ancillary testing depends on cell-block cellularity.

Cervical cancer screening by molecular Pap-transformation of gynecologic cytology.

Cervical cancer is one of the common cancers in women accounting for 7.9% of all cancers. In India it is the second commonest cancer in women. The immortality of the cancer cell and the relatively long time frame from acquisition of infection to development of cervical cancer was established. As major advancements like LBC, HPV testing were introduced in the recent years, screening has taken a new avatar, the Molecular pap!! The objectives of this study were: To compare gynecologic cytology and abnormal res...

Spindle cell lipoma mimicking pleomorphic adenoma: A diagnostic challenge on cytology.

Spindle cell lipoma (SCL) is a benign neoplasm of mature adipose tissue mostly located in the neck, back, and shoulder region. It is composed of a variable admixture of adipocytes, benign spindle cells, and collagen fibres. While the histopathologic features of SCL are quite characteristic and well described, a cytologic diagnosis of SCL might be challenging. We present a case of a 36-year-old female with a swelling in the left preauricular region since last 6 mo. On fine needle aspiration, a diagnosis of l...

Mediastinal seminoma presenting as a neck mass falsely diagnosed as anaplastic thyroid carcinoma: A case report.

Germ cell tumors can occur in the mediastinum. They account for about 20% of tumors at this location. The majority are located in the anterior mediastinum and usually occur in young adult males. Extension of mediastinal germ cell tumors into the neck with mass formation is a very rare and unusual event. Herein, we report a case of a 34 year old male who presented with a progressively enlarging neck mass. Fine Needle Aspiration (FNA) was performed as initial evaluation and showed cellular smears comprising a...

We report two cases of breast cancer metastatic to the skeletal muscle, diagnosed by ultrasound guided fine needle aspiration (US-FNA) biopsy done by interventional cytopathologists at an outpatient cytopathology center. Our two patients presented with lower anterior neck firmness and chest wall mass, respectively. Ultrasound evaluation of our first case demonstrated hypo-echoic thickened anterior strap muscles while in t...

Cytomorphological features of high-grade intraepithelial neoplasia/carcinoma of the cervix following chemoradiotherapy.

Cervicovaginal cytology as a follow-up study in women with a history of a cervical carcinoma treated with chemo-radiotherapy (CRT) plays an important role; however, the cytomorphological characteristics for the diagnosis of high-grade squamous intraepithelial lesions (H-SIL) in post-CRT patients have not been established. The aim of the study is to find the cytomorphological characteristics that support the diagnosis of H-SIL by conventional cytology in these patients.
