Extraskeletal myxoid chondrosarcoma is a rare subtype of sarcoma that affects the soft tissue and bones in middle-aged and elderly adults. Its diagnosis can be challenging, with the differential diagnoses including a wide variety of mesenchymal tumors. The line of differentiation of extraskeletal myxoid chondrosarcoma has been controversial, but recent evidence suggests a neuroendocrine phenotype. INSM1 is a zinc-finger transcription factor that plays a pivotal role in neuroendocrine differentiation, and has been proposed as a promising immunohistochemical marker of neuroendocrine carcinoma...

BACKGROUND: The nucleolus is an organelle that is an ultrastructural element of the cell nucleus observed in H&E staining as a roundish body stained with eosin due to its high protein content. Changes in the nucleoli cytomorphology were one of the first histopathological characteristics of malignant tumors. The aim of this study was to assess the relationship between the cytomorphological characteristics of nucleoli and detailed clinicopathological parameters of melanoma patients. Moreover, we analyzed the correlation between cytomorphological parameters of nucleoli and immunoreactivity of selected proteins responsible for, among others, regulation of epithelial-mesenchymal transition (SPARC, N-cadherin), cell adhesion and motility (ALCAM, ADAM-10), mitotic divisions (PLK1), cellular survival (FOXP1) and the functioning of Golgi apparatus (GOLPH3, GP73)...

Carcinosarcoma of the salivary gland is an extremely rare tumor that is composed of both malignant epithelial and mesenchymal components. Diagnosing carcinosarcoma with fine needle aspiration cytology is challenging because of its overlapping cytomorphologic characteristics with other high-grade malignant salivary gland tumors. Among the many features, including pleomorphic oncocytoid epithelial components, necrotic background, and mitoses, recognizing the singly scattered atypical spindle cells is most essential in carcinosarcoma...

Clear cell tumor of the lung (CCTL) is an extremely rare neoplasm with about 50 cases reported in the literature so far. CCTL belongs to a family arising from putative perivascular epithelioid cells and is otherwise named as "sugar tumor" due to its high cellular glycogen concentration. Due to its rarity, diagnostic features of this entity are not widely known and this usually leads to misdiagnosis. Herein, we report a case of benign CCTL, which was primarily evaluated intraoperatively by FNA cytology and then by a pathological examination of the resected tumor...

BACKGROUND: Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm arising from follicular dendritic cells of germinal centers. The most common site of origin is lymph nodes and it may mimic a variety of tumors at that location, including carcinomas and sarcomas. Diagnosis is frequently missed on cytology as there are very few case reports describing the cytological characteristics of the lesion. Even on histology, a high degree of suspicion is required for an appropriate diagnosis...

OBJECTIVE: Cytomorphologic differentiation of metastatic breast carcinoma from non breast metastases in cytological materials can be difficult. Current breast immunocytochemical markers have low sensitivities. Transcription factor GATA 3 is a promising marker for detecting breast differentiation in cytological materials. The aim of the study was to assess the diagnostic value of GATA 3 as a breast differentiation marker in metastatic cytological materials and to compare it with expression of mammaglobin and gross cystic disease fluid protein-15 (GCDFP-15)...

Transitional cell carcinoma (TCC) arising from renal pelvis rarely gives rise to cutaneous metastasis. Due to the insufficient literature, the exact incidence is not known till date. Moreover, the diagnosis is confirmed on histopathological examination with the aid of immunohistochemistry wherever needed. We are presenting a case of a 70-year-old female with metastatic TCC from the renal pelvis to the abdominal skin, which was diagnosed on cytology alone along with the cell block preparation. We also highlight the important cytomorphological and immunohistochemical features noted, which need to be known to avoid any diagnostic delay...

We herein report a rare case of acute basophilic leukemia with t(16;21)(p11;q22) generating the FUS-ERG fusion gene. The basophilic nature of leukemia blasts was demonstrated by cytomorphology, toluidine blue metachromasia, mature basophil-associated antigen expression, and characteristic granules under electron microscopy. The molecular link between t(16;21)/FUS-ERG and basophilic differentiation remains unclear.

ALK-positive histiocytosis is a recently described rare histiocytic proliferative disorder of early infancy. When infants present with anemia, thrombocytopenia, and hepatosplenomegaly, this entity should be included in the differential diagnosis along with hemophagocytic lymphohistiocytosis, metabolic/storage diseases, hematopoietic malignancies, and autoimmune thrombocytopenia. We report 2 new cases of ALK-positive histiocytosis, one with kidney involvement and the other with extensive bone marrow involvement in addition to an overt liver disease...

Lymphoepithelioma-like carcinoma (LELC) is a rare variant of cervical squamous cell carcinoma with unclear HPV and EBV association. Due to the accompanying and often obscuring lymphocytic inflammation, malignant cells may be difficult to recognize on cytologic samples and can mimic several more common benign and atypical cervical lesions. In this case report, we describe the cytomorphologic findings of LELC by liquid-based cytology in a 59-year-old Caucasian woman who was positive for high risk HPV but had no visible cervical lesions...

The gold standard for diagnosis of central nervous system lymphomas still regards a stereotactic brain biopsy, with the risk of major complications for the patient. As tumor cells can be detected in cerebrospinal fluid (CSF), CSF analysis can be used as an alternative. In this respect, mutation analysis in CSF can be of added value to other diagnostic parameters such a cytomorphology and clonality analysis. A well-known example of targeted mutation analysis entails MYD88 p.(L265P) detection, which is present in the majority of Bing Neel syndrome and primary central nervous system lymphoma (PCNSL) patients...

Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue tumors commonly arising from nerve roots in the extremities with a predilection in neurofibromatosis (NF) patients. MPNSTs are known to behave aggressively, with worse prognosis in nonresectable cases, and a 5-year survival of about 52% and 15% in resectable and unresectable cases, respectively. Although cytological diagnosis in a known case of NF-1 is possible, however, in the absence of any associated syndrome in a sporadic case, it is very challenging to accurately diagnose this tumor...

Acral melanoma occurring on the palms, soles, and nails is the most common subtype of cutaneous melanoma in Asians. Genetic alterations in acral melanoma and acral melanocytic nevus are not well known. We performed next-generation sequencing and evaluated the correlations between genetic information and the clinicopathologic characteristicsfrom 85 Korean patients with acral melanocytic neoplasms. Of the 64 patients with acral melanoma, most had ≥ T2 stage, and the heel was the most common anatomical site of melanoma (n = 34, 53...

BACKGROUND: Fine-needle aspiration (FNA) is routinely performed to evaluate salivary gland lesions, and provides valuable information regarding the cytomorphologic features of the lesions. Occasionally, there are overlaps between benign and malignant conditions due to heterogeneity of the cell types, metaplastic changes, and sampling issues. Herein, the authors present a retrospective study of diagnostic pitfalls in salivary gland cytology and the simulating conditions. METHODS: A 20-year retrospective review (1995-2015) of medical records was performed searching for the cytology reports of patients who underwent FNA of the salivary gland with the words "amendment" or "revision...
