Parachordoma is an extremely rare soft tissue tumor of unknown lineage. Parachordoma develops most often on the extremities. Only 2 cases have been reported as pelvic parachordoma. A 46-year old Egyptian woman with a huge painful pelvic mass was found to have a parachordoma with ectopic pelvic right kidney. There is only one report in the literature of fine needle aspiration cytology in this setting. The microscopic picture of parachordoma is not new to pathologists but the gross picture of this rare tumor has not previously been published; not even in the World Health Organization classification of soft tissues tumors. Diagnosis was confirmed by immunohistochemistry. The patient is in good clinical condition without any evidence of recurrence or metastasis after 84 months of follow up.

Needle Aspiration Cytology

Context The World Health Organization system for lymphoma classification relies on histologic findings from excisional biopsies. In contradistinction to expert guidelines, practitioners increasingly rely on fine-needle aspiration cytology and core needle biopsies rather than excisional biopsies to diagnose lymphomas. Objective To determine a rate at which fine-needle aspiration cytology and core needle biopsies, combined with flow cytometry and/or genetic techniques, can provide a diagnosis sufficient for optimal medical management of lymphoma. Data Sources The English-language literature on fine-needle aspiration cytology and core needle biopsies for lymphoma was reviewed to identify studies that provided interpretations of all specimens regardless of whether these were deemed diagnostic. Conclusions Forty-two studies (1989–2012) specified the lymphoma subtypes for each diagnosis or indicated a rate at which the methods failed to provide a diagnosis. The median rate at which fine-needle aspiration cytology and core needle biopsies yielded a subtype-specific diagnosis of lymphoma was 74%. Strictly adhering to expert guidelines, which state that follicular lymphoma cannot be graded by these techniques, decreased the diagnostic yield further to 66%. Thus, 25% to 35% of fine-needle aspirates and/or core biopsies of nodes must be followed by an excisional lymph node biopsy to fully classify lymphoma.

Carcinoma showing thymic-like differentiation (CASTLE) is a rare tumor most commonly occurring in the thyroid and soft tissues of the neck. We report the first case of CASTLE occurring in the sublingual gland. The patient, a 35-year-old healthy man, presented with a submucosal lesion located in the anterior right floor of the oral cavity and an ipsilateral neck mass. The lesion had been previously investigated by neck computed tomography and ultrasound-guided fine needle aspiration cytology and diagnosed as metastatic squamous cell carcinoma. After oral cavity magnetic resonance imaging, positron emission tomography, and a non-diriment, fine needle aspiration cytology of the sublingual mass, the patient was treated as affected by a sublingual gland malignancy with removal of primary tumor and neck dissection. Morphological and immunohistochemical findings were diagnostic for primary sublingual gland CASTLE. The patient received adjuvant radiotherapy and is free of disease 2 years after treatment. We describe the pathological features of the lesion and discuss the possible differential diagnoses.

Objective: To evaluate the role of Fine Needle Aspiration Cytology in the preoperative diagnosis of malignancy in parotid and submandibular gland neoplasm. Methods: This cross sectional study on 50 cases was conducted in the Department of Otolaryngology and Head-Neck Surgery of Sir Salimullah Medical College Mitford Hospital and Dhaka Medical College Hospital from January’2009 to June 2010. Results: Fine needle aspiration cytology findings of our all 50 cases were compared with postoperative histopathological reports. Out of the 50 cases, in 36(72%) cases of benign neoplasm and 7(14%) cases of malignant neoplasm, pre-operative FNAC findings and post operative histopathological findings were same. In 7 cases, FNAC and post operative histopathological findings did not matched. These were 2 (4%) false positive and 5 (10%) false negative result.In our study sensitivity of FNAC for reporting malignancy was 58.33%, specificity to rule out malignancy was 94.73% and overall accuracy in detecting malignant tumour was 86%. Positive predictive value and negative value were 77.77% and 87.80% respectively. It can be concluded that fine needle aspiration cytology is a safe, cheap and useful preoperative diagnostic tool in the diagnosis of malignancy in parotid and submandibular gland, but as fine needle aspiration cytology partly depends on operator skill, it may give false negative and false positive result. Conclusion: FNAC is a useful preoperative diagnostic tool for malignant parotid and submandibular glands with high specificity and sensitivity.
