Image-guided fine-needle aspiration cytology of ovarian tumors: An assessment of diagnostic efficacy
Ghazala Mehdi, Veena Maheshwari, Sheerin Afzal, Hena A Ansari, Maryem Ansari
July-September 2010, 27(3):91-95
DOI:10.4103/0970-9371.71872  PMID:21187883
Background : Image-guided fine-needle aspiration cytology (FNAC) of ovarian lumps is being increasingly used for the successful diagnosis of ovarian tumors, although borderline cases may be difficult to diagnose by this method. Aim : To demonstrate the efficacy of image-guided FNAC in diagnosing ovarian tumors (benign and malignant) and to evaluate the usefulness of cytology as a mode of easy and rapid diagnosis of ovarian lumps. Materials and Methods : The study was conducted on 42 female patients. Clinical evaluation and relevant investigations were carried out. Diagnosis was established by FNAC performed under image guidance (ultrasonography/computed tomography). The cytological diagnosis was confirmed by histopathological examination. Results : Cytological diagnosis was rendered on all the 42 ovarian lesions, with a correct diagnosis in 34 cases, resulting in a diagnostic accuracy of 80.9%. Most of the cases with discordant diagnoses were surface epithelial tumors of low malignant potential and required histopathological examination for a final diagnosis. Conclusions : Image-guided FNAC is an inexpensive, rapid and fairly accurate procedure for the diagnosis of ovarian lesions. It provides a safe alternative to the more expensive, time consuming and cumbersome surgical route to diagnosis.

Squash preparation: A reliable diagnostic tool in the intraoperative diagnosis of central nervous system tumors
Sumit Mitra, Mohan Kumar, Vivek Sharma, Debasis Mukhopadhyay
July-September 2010, 27(3):81-85
DOI:10.4103/0970-9371.71870  PMID:21187881
Background : Intraoperative cytology is an important diagnostic modality improving on the accuracy of the frozen sections. It has shown to play an important role especially in the intraoperative diagnosis of central nervous system tumors. Aim: To study the diagnostic accuracy of squash preparation and frozen section (FS) in the intraoperative diagnosis of central nervous system (CNS) tumors. Materials and Methods : This prospective study of 114 patients with CNS tumors was conducted over a period of 18 months (September 2004 to February 2006). The cytological preparations were stained by the quick Papanicolaou method. The squash interpretation and FS diagnosis were later compared with the paraffin section diagnosis. Results : Of the 114 patients, cytological diagnosis was offered in 96 cases. Eighteen nonneoplastic or noncontributory cases were excluded. Using hematoxylin and eosin-stained histopathology sections as the gold standard, the diagnostic accuracy of cytology was 88.5% (85/96) and the accuracy on FS diagnosis was 90.6% (87/96). Among these cases, gliomas formed the largest category of tumors (55.2%). The cytological accuracy in this group was 84.9% (45/53) and the comparative FS figure was 86.8% (46/53). In cases where the smear and the FS diagnosis did not match, the latter opinion was offered. Conclusions : Squash preparation is a reliable, rapid and easy method and can be used as a complement to FS in the intraoperative diagnosis of CNS tumors.

Scar endometriosis
Zaheer Abbas Ali Khan Pathan, US Dinesh, Ravikala Rao

Endometriosis is the presence of functioning endometrium outside the uterus. Endometriosis rarely occurs in the abdominal wall. Majority of abdominal wall endometriosis occur in or adjacent to surgical scars, following caesarean section or hysterectomy. Laparotomy scar endometriosis following salpingectomy for ectopic pregnancy has rarely been reported. We report a case of scar endometriosis following laparotomy for chronic ectopic, and diagnosed by fine needle aspiration cytology (FNAC). Excision biopsy confirmed the FNAC diagnosis of scar endometriosis.

Role of scrape cytology in the intraoperative diagnosis of tumor
Sachin S Kolte, Rahul N Satarkar
July-September 2010, 27(3):86-90
DOI:10.4103/0970-9371.71871  PMID:21187882
Background : Rapid diagnosis of surgically removed specimens has created many controversies and a single completely reliable method has not yet been developed. Histopathology of a paraffin section remains the ultimate gold standard in tissue diagnosis. Frozen section is routinely used by the surgical pathology laboratories for intraoperative diagnosis. The use of either frozen section or cytological examination alone has an acceptable rate (93-97%) of correct diagnosis, with regard to interpretation of benign versus malignant. Aim : To evaluate the utility of scrape cytology for the rapid diagnosis of surgically removed tumors and its utilisation for learning cytopathology. Materials and Methods : 75 surgically removed specimens from various organs and systems were studied. Scrapings were taken from each specimen before formalin fixation and stained by modified rapid Papanicolaou staining. Results : Of the 75 cases studied, 73 could be correctly differentiated into benign and malignant tumors, with an accuracy rate of 97.3%. Conclusions : Intraoperative scrape cytology is useful for intraoperative diagnosis of tumor, where facilities for frozen section are not available. The skill and expertise developed by routinely practicing intraoperative cytology can be applied to the interpretation of fine needle aspirate smears. Thus, apart from its diagnostic role, intraoperative cytology can become a very useful learning tool in the field of cytopathology.

Plasmacytoma of tonsil diagnosed by fine-needle aspiration cytology
Ramachandra V Bhat, KM Prathima, ML Harendra Kumar, GK Narayana
July-September 2010, 27(3):102-103
DOI:10.4103/0970-9371.71875  PMID:21187876
Extramedullary plasmacytoma of tonsil is rare. Even though biopsy is necessary for final diagnosis, fine-needle aspiration cytology (FNAC) can provide useful information in the management of such cases. We report a case of plasmacytoma of tonsil diagnosed by FNAC in a 43-year-old man who presented with a swelling in the right tonsillar area. FNAC smears revealed sheets of plasma cells at various stages of maturation. Subsequent histopathological and immunohistochemical studies confirmed the diagnosis of plasmacytoma. This case is reported for the rarity of site for extramedullary plasmacytoma and to highlight the usefulness of FNAC in lesions of tonsil.

The cytology of giant solitary trichoepithelioma
Jayashree Krishnamurthy, KN Divya
July-September 2010, 27(3):99-101
DOI:10.4103/0970-9371.71874  PMID:21187885
Giant solitary trichoepithelioma (GST) is a rare trichogenic tumor, which may present as a pigmented lesion. An 80-year-old man was diagnosed to have giant solitary trichoepithelioma on fine-needle aspiration cytology. The cytological findings represented the histological features. The recognition of GST is important because of its close resemblance to basal cell carcinoma and other skin adnexal tumors - clinically, cytologically and histologically.

Vaishali A Walke, Suprita P Nayak, Maitreyee M Munshi, Sudhakar K Bobhate
July-September 2010, 27(3):96-98
DOI:10.4103/0970-9371.71873  PMID:21187884
Chondromyxoid fibroma (CMF) is an unusual tumor that predominantly affects long bones of young adults. We present two cases of CMF that were diagnosed on cytology. The specific cytological features included varying combinations of chondroid, myxoid and fibroid elements. These features when correlated with clinico-radiological findings helped to arrive at a correct diagnosis. Thus a definitive diagnosis of CMF can be made on cytology based on which further line of treatment can be planned.

Aggressive digital papillary adenocarcinoma diagnosed by fine needle aspiration cytology
Jayashree Krishnamurthy, Bindu Patil
July-September 2010, 27(3):109-111
DOI:10.4103/0970-9371.71878  PMID:21187879
Aggressive digital papillary adenocarcinoma is a rare variant of eccrine sweat gland malignancy with a propensity for metastases and recurrence. We report a 45-year-old female with aggressive digital papillary adenocarcinoma diagnosed by fine needle aspiration cytology (FNAC). The cytological findings were representative of the histological features. The recognition of aggressive digital papillary adenocarcinoma as a distinct clinicopathological eccrine sweat gland neoplasm is important because of the potential for aggressive local growth and distant metastasis. FNAC plays an important role in the preoperative diagnosis and management of these lesions.

Cytodiagnosis of glomus tumor
Sumana Mukherjee, Gautam Bandyopadhyay, Sandeep Saha, Manoj Choudhuri
July-September 2010, 27(3):104-105
DOI:10.4103/0970-9371.71876  PMID:21187877
Glomus tumors are uncommon, with an estimated incidence of 1.6%. Cytological descriptions of this tumor are few. We report a 15-year-old boy presenting with a painful subungual swelling. Fine needle aspiration cytology showed uniform cells with homogeneous chromatin and scanty cytoplasm. Cytology was reported as "suggestive of glomus tumor". Histopathological examination confirmed the diagnosis. Careful cytomorphological examination supported by appropriate clinical history should suggest the diagnosis of glomus tumor and help in preoperative diagnosis.
