Phaeohyphomycosis is an unusual granulomatous fungal infection, observed in immunocompromised or diabetic patients; however, it is even rarer in immunocompetent patients. Cytological findings of the same have been infrequently reported. The histopathological diagnosis or fungal culture helps in definitive diagnosis to identify the exact fungal species. Hereby, we report a rare case of invasive fungal infection in a breast lump in a young female, presenting as fibroadenoma breast. Fine needle aspiration cytology from the breast lesion showed the presence of septate acute-angled branching fungal hyphae with focal pigmentation, morphologically suggestive of phaeohyphomycosis which was positive with fungal stains...

Metastatic carcinoma to the pancreas is uncommon and head and neck squamous carcinoma metastatic to the pancreas is extremely rare. Metastatic squamous cell carcinoma to the pancreas presents a unique diagnostic challenge: in addition to mimicking the rare primary squamous cell carcinoma of the pancreas based on cytologic, histologic, and immunohistochemical features, it may be mistaken for a cystic neoplasm of the pancreas because of its high predilection for cystic degeneration in metastatic sites. Herein, we report a case of tonsillar squamous cell carcinoma with a cystic pancreatic metastasis diagnosed by ultrasound-guided fine needle aspiration biopsy (EUS-FNA)...

Chondrosarcoma (CS) of larynx is a rare laryngeal tumor accounting about 1% of laryngeal malignancies. When CS arises from thyroid cartilage, it may clinically present as a thyroid nodule. Here we report a rare case of CS of thyroid cartilage misinterpreted as medullary thyroid carcinoma. The main aim of this case report is to emphasize the important role of accurate clinical history, appropriate physical examination, and proper localization of the tumor and clear definitive imaging in conjunction with interpretation of cytologic smears...

Herein, we present a rare case of intracranial extramedullary hematopoiesis (EMH) diagnosed by cerebrospinal fluid (CSF) cytology and describe the clinical presentation, radiologic, and pathologic findings. A 65 year-old man with a history of progressing primary myelofibrosis was admitted for headaches and right facial numbness. A brain MRI revealed focal abnormalities that were suspicious for leptomeningeal involvement of acute leukemia. Cytologic examination of CSF demonstrated a hypercellular specimen composed of hematopoietic cells including few blasts, as well as maturing red blood cells and granulocytic cells...

BACKGROUND: Metastatic tumors to the pancreas are rarely encountered and diagnostically challenging. We aspired to determine the incidence and origin of all metastases to the pancreas at our institution, and to examine their clinicopathologic and cytomorphologic features. We also sought to ascertain the effect of endoscopic ultrasound (EUS) guidance implementation. METHODS: A search of our database was undertaken to review all pancreatic FNA and/or CNB examined from January 2000 through December 2014...

INTRODUCTION: The objective of this study was to evaluate the role of intraoperative frozen section (IFS) in determining the course of surgery in thyroid nodules with a prior fine needle aspiration (FNA) biopsy diagnosis. In addition, reliability of FNA interpretation to guide surgical management without IFS was investigated. MATERIAL AND METHODS: This is a retrospective study of all patients who had a FNA biopsy, IFS, and final pathology performed on a thyroid nodule over a 9 month period...

BACKGROUND: We previously found that the presence of atypical urothelial tissue fragments (AUTF) was associated with an increased risk of high-grade urothelial carcinoma (HGUC) but not low-grade urothelial neoplasia (LGUN) in voided urine (VU) specimens. However, we subsequently found that patients with LGUN were more likely to have cytologic atypia in urinary washing (UW) specimens, suggesting that cytologic atypia found in UW specimens might be associated with both LGUN and HGUC. In this study, we retrospectively examined UW specimens containing AUTF to determine whether they were associated with HGUC, LGUN, or both HGUC and LGUN...

The 2008 World Health Organization (WHO) classification of hematopoietic and lymphoid tissues has been recently revised, and publication of the updated 2016 version is expected soon. Given that cytopathologists are often involved in the diagnosis of primary, recurrent, and transformed lymphoproliferative disorders, knowledge of updates to the WHO lymphoma classification, including terminology, pathogenesis, ancillary techniques, and targeted therapies is necessary. Herein, we reference the last decade of cytology specific literature for seven newer B-cell disorders and provide illustrative examples of each entity from our files...

Lung cancer is one of the most common cancer types in men and women worldwide with a high mortality rate. World Health Organization (WHO) classification has accepted biopsy as the primary sample for lung cancer diagnosis, pathological classification and molecular testing for management of patients, yet, the use of alternative sampling procedures is highly encouraged. Bronchial cytological samples require a less invasive collection technique and may be suitable for pathological and molecular analysis and storage in liquid medium...

Significant changes in cervical cancer screening practice, guidelines, and prevention of cervical cancer have taken place in recent years including the raising of initial cervical cancer screening age, changes in frequency of cytology screening, and the adoption of high risk HPV and cytology co-testing for some patients; the introduction of the bivalent, quadrivalent, and 9-valent HPV vaccines; and the recent approval of high risk HPV testing as primary screening with the use of cytology as triage in positive cases...

The purpose of the Papanicolaou (Pap) smear is to detect primary squamous lesions of the uterine cervix. Although most successful at detection of squamous lesions, the Pap may also detect metastatic carcinomas, sarcomas, and melanomas. We report two rare cases of myeloid sarcoma (MS) of the uterine cervix identified on screening Pap smears with concurrent confirmatory cervical biopsies. The purpose of our study is to identify and report cytologic features of MS on Pap smears utilizing a liquid-based ThinPrep method, which has not been previously documented in literature...

Cytologic diagnosis of extra-adrenal paraganglioma presenting as a peripancreatic mass is challenging with a high error rate due to its rarity. We report two cases of peripancreatic masses identified by radiology. Endoscopic ultrasound-guided fine needle aspiration (FNA) of the masses showed a moderately cellular tumor composed of small to medium sized neoplastic cells with round to oval nuclei, arranged singly and in loose clusters. Focal rosette-like structures were present. The cells were positive for neuroendocrine markers (synaptophysin and chromogranin)...

Cells with long polar hair-like processes referred to as 'flower pot cells' are a rare but beautiful morphological feature observed in effusions of diverse etiologies. This report describes these cells in effusions seen in ovarian borderline serous tumours, malignant mesothelioma and in reactive mesothelial cells with or without accompanying malignant cells. These processes were better appreciated in air-dried May-Grunwald-Giemsa stained smears.

BACKGROUND: Cytological examination of voided urine (VU) can reliably diagnose high-grade urothelial carcinoma (HGUC) of the lower urinary tract, but its value in the diagnosis of upper tract HGUC (UTHGUC) is less well-established. To clarify the utility of VU in the setting of UTHGUC, we examined urinary specimens from patients with UTHGUC on follow-up surgical pathology. METHODS: 52 VU specimens (47 patients) with subsequent biopsy-proven UTHGUC were identified over a 12-year period; 32 had a corresponding upper tract urinary washing (UW) specimen...

Synovial sarcoma (SS) is a soft-tissue sarcoma which usually occurs in lower extremities. Less than 20 cases of SS located in shoulder or axillary region have been reported, and these studies describe histopathological features. We report a case of axillary SS diagnosed by fine-needle aspiration cytology, immunocytochemistry, and molecular techniques performed on cytology smears. A 48-year-old woman presented with a palpable and well-defined axillary mass which measured 4 cm. On-site smears showed high cellularity with spindle cells, and a mesenchymal tumor was suspected...
