Abstract
Soft tissue neoplasms pose many diagnostic challenges on fine-needle aspiration (FNA), owing largely to their rarity, large number of entities, and histologic diversity. Advances in ancillary testing now allow detection of the characteristic immunophenotypes and molecular alterations for many neoplasms and include reliable surrogate immunohistochemical markers for underlying molecular events that are highly efficient in small biopsies. A morphology-based framework is recommended to guide appropriate differentials and judicious selection of ancillary tests for small biopsies. The accurate diagnosis of soft tissue tumors is crucial for patient management and prognostication, with many potential implications in this era of precision medicine.

Application of the international system for reporting serous fluid cytopathology on pleural effusion cytology with paired pleural biopsy: A new insight and novel approach on risk of malignancy. Cytopathology 2024. [PMID: 39091111 DOI: 10.1111/cyt.13423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 06/14/2024] [Accepted: 07/02/2024] [Indexed: 08/04/2024]
Abstract
INTRODUCTION The risk of malignancy (ROM) remains an area of interest for further evaluation in reporting systems including in International System for reporting serous fluid cytopathology (TIS), which is a standardized system for reporting effusion cytology. Herein, we report our findings in further investigation of ROM in TIS by studying on paired pleural effusion specimens and corresponding pleural biopsies with emphasis on negative for malignancy, and atypia of undetermined significance categories. MATERIALS AND METHODS The Johns Hopkins Hospital pathology database was retrospectively searched for patients with a pleural biopsy (PBX) and a paired pleural effusion (PF) cytology specimens over a 4-year period. We employed the TIS categories. The following statistical parameters were evaluated: sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and ROM. RESULTS A total of 223 patient cases were included. Effusions TIS reclassification and ROM were as follows: 1.8% non-diagnostic (ROM 75%), 75.8% negative for malignancy (ROM 23%), 4.9% atypical cells of undetermined significance (ROM 45%), 2.2% suspicious for malignancy (ROM 80%), and 15.2% malignant (ROM 100%). Overall accuracy, sensitivity, specificity, PPV and NPV were calculated and were 79.4%, 45%, 97.7%, 91.2% and 77%, respectively. Among, discordant cases diagnosed negative for malignancy on PF and positive for malignancy on PBX, there were significant number of lymphomas, mesotheliomas, and sarcomas. Lung cancer was the most common carcinoma; however, rare types of carcinomas were noted. Cells blocks and immunohistochemistry (IHC) studies were utilized to confirm either malignant conditions or rule out malignancy in both cell blocks and histology biopsies. CONCLUSION This study demonstrates the high specificity and ROM for 'malignant' and 'suspicious for malignancy' categories in the TIS reporting system and highlights the modest negative predictive value for the 'negative for malignancy' category. Although Tissue biopsies are usually considered as 'gold standard', any definitive diagnosis of malignancy of body fluid should be considered positive for malignancy in further clinical decision-making.

Abstract
INTRODUCTION AND IMPORTANCE Angiosarcomas are an exceedingly rare and malignant form of soft tissue sarcoma that are derived from endothelial cells. Overall, they comprise <1 % of the total number of soft tissue sarcomas. Due to nonspecific and misleading symptoms, the subsequent clinical presentations can easily result in misdiagnosis. This leads to life-threatening complications for patients. Contemplating this tumor as a differential diagnosis during the preoperative phase allows for essential time-sensitive therapeutic interventions to be accomplished. CASE PRESENTATION Herein, we present the seldom precedented case of a 66-year-old Middle Eastern male who came to our surgical clinic chiefly complaining of an exacerbation of chronic left hypochondriac pain accompanied by gradual inexplicable abdominal distention. Our diagnostic radiological evaluation demonstrated two isolated abdominal mass formations. CLINICAL DISCUSSION Sheer excision of the neoplastic masses with safety margins was successfully executed via open surgery. The stemming histopathological examination through Hematoxylin and Eosin and immunohistochemical staining established the definitive diagnosis of an Epithelioid Angiosarcoma. CONCLUSION Epithelioid Angiosarcomas belong to the category of profoundly rare tumors. The available published literature conveys this rarity through the scarcity of epidemiological parameters and studies. It necessitates being borne in mind when facing similar clinical scenarios so that apt therapeutic interventions can be achieved. Structured diagnostic methods, timely surgical interventions and proper techniques, and comprehensive follow-up patient surveillance protocols are, therefore, merited. After thorough review of the published literature, we reckon herewith that ours is the first documented case from our country of an Epithelioid Angiosarcoma.

Abstract
Primary hepatic angiosarcoma (PHA) is a rare, rapidly growing, highly aggressive hepatic malignancy, primarily seen in elderly males. Establishing an accurate clinical diagnosis is challenging owing to its rarity and nonspecific presentation. Rendering a cytologic diagnosis of PHA is extremely difficult, and immunocytochemistry(ICC) on cell block(CB) sections is essential to confirm the diagnosis. The characteristic cytomorphologic features of PHA have rarely been documented, further augmenting the diagnostic challenge. A 32-year-old male presented with abdominal pain, abdominal distension, and significant weight loss over the past 9 months. On examination, the abdomen was distended, with multiple spider angiomas and a large mass in the right hypochondrium. His renal function tests, liver function tests, and serum tumor markers were within normal limits. An abdominal triphasic computerized tomography revealed a large lobulated mass in the right lobe with central necrosis. An ultrasound-guided FNA was performed from the liver lesion. The cytologic smears showed singly scattered large, markedly pleomorphic, epithelioid-elongated tumor cells having oval-elongated nuclei, irregular nuclear contours, coarse chromatin, prominent macronucleoli, and abundant finely vacuolated cytoplasm in a background of blood. ICC on the CB demonstrated diffuse positivity for vimentin, CD31, and nuclear positivity for FLI-1, confirming a vascular origin. Hence, a final cytologic diagnosis of primary hepatic angiosarcoma was rendered. The index report describes the characteristic cytomorphologic and immunocytochemical features of a rare hepatic malignancy in a young male and reiterates the usefulness of FNAC coupled with CB-ICC in the quick and precise diagnosis of such challenging cases.

Abstract
Vascular neoplasms are rare tumors with a multitude of clinical presentations and behavior, which make accurate identification and subclassification challenging on limited small biopsies. Within the spectrum of these lesions, the ones with epithelioid morphology, such as epithelioid hemangioendothelioma and epithelioid angiosarcoma, are particularly challenging given the morphologic overlap with nonvascular lesions and the limited cells due to hemodilution on sampling. Herein, we review the differential diagnosis of epithelioid vascular neoplasms, with a focus on the cytomorphology, differential diagnoses, and ancillary studies that pathologists should be aware of when evaluating small biopsies and aspirates, including novel translocations, and associated monoclonal immunohistochemistry antibodies, that can help in the diagnosis of some of these tumors. Awareness of these morphologic and ancillary study findings in these rare tumors will hopefully allow pathologists to recognize and render-specific diagnoses on limited samples of these challenging lesions.

Abstract
Epithelioid angiosarcoma (EA) is a highly aggressive vascular neoplasm. Primary mediastinal EA is extremely rare with only few cases reported in the English literature. We herein present a case of a 78-year-old patient, who was found to have a right superior mediastinal mass associated with mediastinal and hilar lymphadenopathy. Endobronchial ultrasound guided fine needle aspiration cytology of a station 4R lymph node revealed a cellular, discohesive malignant neoplasm displaying primarily epithelioid morphology with occasional spindled, plasmacytoid, and tumor giant cells. The tumor cells had ample eosinophilic cytoplasm with pleomorphic nuclei and prominent nucleoli. Vasoformative features were noted, exemplified by widespread cytoplasmic vacuoles containing neutrophils and rare red blood cells (hemophagocytosis) and vascular channels identified solely in the cell block. By immunohistochemistry, the tumor cells stained strongly positive for vimentin, positive for ERG, CD-31, FLI-1, and focally positive for pan-cytokeratin. The cytomorphological features and immunostaining patterns were diagnostic of EA. No history of malignancy was reported, and no other lesions were identified on imaging. The diagnosis of primary mediastinal EA on cytology and small biopsy specimens may be challenging due to the rarity of this tumor, limited diagnostic material, and overlapping morphologic features with other entities in the differential diagnosis. A high index of suspicion, especially in cases with vasoformative features, and utilization of ancillary studies can help establish the diagnosis.

Abstract
Angiosarcoma is a rare malignant tumor of vascular origin (<2% of sarcomas). It represents <1% of all head-neck malignancies. A cytological diagnosis on fine needle aspiration (FNA) is extremely difficult. Most tumors yield a predominantly hemorrhagic aspirate with only rare neoplastic cells, a diagnostic pitfall of aspiration cytology of vascular lesions. An 81-year-old male, 2 years status post resection of a nasal tip angiosarcoma and adjuvant radiation therapy, presented to another institution with an enlarging left neck mass of 2 months duration. Outside FNA diagnosis of cyst was made. Patient was referred to our institution for a pathologist-performed ultrasound-guided FNA. Ultrasound examination revealed a hypoechoic cystic left neck mass. Direct smears showed blood with occassional single malignant spindled to epithelioid cells, with some cells showing "spider-leg" like cytoplasmic processes/projections and "tadpole/fiber" like morphology. Immunohistochemistry performed on cell block sections revealed the tumor cells to be positive for D2-40, CD31 and CD34, supported a diagnosis of regional recurrent angiosarcoma. Left neck dissection showed recurrent high-grade angiosarcoma infiltrating periparotid soft tissues and metastatic angiosarcoma involving multiple lymph nodes. A diagnosis of angiosarcoma on FNA samples can be challenging, as the aspirate may contain only rare tumor cells hidden in a background of abundant blood. Such cases require careful screening to avoid an incorrect diagnosis of inadequate or cyst contents. This short review highlights key cytomorphologic features of angiosarcoma, includes novel cytologic features of angiosarcoma which has not been described previously and also discusses challenges and diagnostic pitfalls of FNA of vascular lesions.

Abstract
Thyroid tumors can be classified into epithelial, nonepithelial, and nonprimary lesions. Nonepithelial thyroid tumors are rare. They can be of primary origin within the thyroid gland, arise secondary to contiguous growth from adjacent tissues, or represent metastatic disease. The incidence of nonepithelial tumors of the thyroid is only 1% to 2%, most of which are lymphomas; the remainder includes mesenchymal and histiocytic tumors. This review examines the cytohistological features of various nonepithelial and nonlymphoid tumors of the thyroid, including vascular lesions, neural tumors (including granular cell tumor and paraganglioma), smooth muscle tumors, solitary fibrous tumor, histiocytic neoplasms (eg, Langerhans cell histiocytosis and Rosai-Dorfman disease), and follicular dendritic cell sarcoma. Their differential diagnosis is discussed, including recommendations to prevent the pitfall of mistaking these rare tumors for more common epithelial thyroid neoplasms.

Abstract
Fine needle aspiration (FNA) cytology is a sparsely used diagnostic method in the evaluation of mediastinal sarcomas in most medical centers worldwide with most literature citations regarding this category of malignancies consisting of small series and individual case reports. Most of these published studies highlight vascular sarcomas such as epithelioid hemangioendothelioma, and angiosarcoma, various subtypes of liposarcoma including well-differentiated liposarcoma, myxoid liposarcoma, and pleomorphic liposarcoma, malignant peripheral nerve sheath tumor, and sarcomas of uncertain differentiation, primary synovial sarcoma and the Ewing sarcoma family of tumors. This paucity of cytopathology reports regarding mediastinal sarcomas is in marked contrast to the almost daily application of endobronchial ultrasound (EBUS)-guided FNA biopsy for sampling mediastinal lymph nodes and mediastinal masses for primary and metastatic carcinomas which, of course, are considerably more common that any type of sarcoma in this location. EBUS, endoscopic ultrasound-guided (EUS) needle biopsy, and percutaneous image-guided biopsy using either core needle, fine-needle, or both can serve a potentially useful role for diagnostic sampling of mediastinal sarcomas, be they primary or metastatic. This review catalogues much of the published data regarding FNA cytopathology and its application to mediastinal sarcomas. An attempt is made to primarily highlight case series rather than individual case reports; however, due to the paucity of these, case reports are cited and discussed where appropriate.

Abstract
INTRODUCTION As a rare soft tissue malignancy, epithelioid sarcoma (EpS) is infrequently subjected to cytopathologic analysis. With the exception of a few series, the cytology literature regarding EpS is largely limited to single case reports. Our purpose was to evaluate our experience with EpS, and review the literature regarding its cytopathology. MATERIALS AND METHODS A search was made of our cytopathology and surgical pathology databases for cases diagnosed as EpS. Fine-needle aspiration biopsy smears and imprint smears were performed and examined using standard technique. Effusion samples were processed using liquid-based slides. RESULTS Twenty cases of EpS were retrieved from 10 patients (M:F 1:1; mean age = 36 years). One patient had 5, 1 patient had 3, and 3 patients had 2 separate specimens. All patients had prior or subsequent tissue confirmation of EpS; all were of the classic/distal type. Seven were new patient cases, 7 were locally recurrent, and 6 were metastases. Sites included lower extremity (8 cases), upper extremity (4), trunk (4), serous effusion (2), scalp (1), and mediastinum (1). Specific cytologic diagnosis were EpS (13 cases), sarcoma not otherwise specified (5), and malignant neoplasm (2). All cases where cell-block SMARCB-1 staining was used were specifically recognized as EpS. Cytomorphology was composed primarily of epithelioid/plasmacytoid cells having eccentrically positioned nuclei, moderate cytoplasm, and variable nuclear pleomorphism. CONCLUSION The cytopathology of EpS is somewhat variable, morphologically non-specific, and mimics that of other neoplasms with epithelioid features. Ancillary immunostaining is necessary for a specific diagnosis in newly encountered patients.

Abstract
Soft tissue neoplasms are increasingly being sampled by core needle biopsy and fine-needle aspiration (FNA), and these small biopsy specimens pose unique diagnostic challenges. Many advances in ancillary testing enable detection of characteristic immunophenotypes and molecular alterations, allowing accurate classification of soft tissue tumors in these small biopsy samples. This review outlines pattern-based diagnostic approaches to core biopsies and FNAs of soft tissue neoplasms, including formulation of practical differential diagnoses and relevant application of ancillary tests.

Abstract
Epithelioid hemangioendothelioma (EHE) is a rare mesenchymal tumor of vascular origin with variable morphological features and unpredictable biological behavior. EHE occasionally involves the pleural fluid. However, the cytomorphology of EHE found in pleural fluid has not been well characterized in the literature. Herein we describe a case of EHE, initially presenting as multiple liver lesions plus several small nodular densities at the bases of the lungs followed by bilateral pleural effusions.
